Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, specifically to a method and system for welding ship weld markings. Background Technology

[0002] With the development of global trade, maritime transport has gradually become an important mode of transportation for trade. At the same time, in order to respond to market demand, more and more large shipping companies have begun to produce different types of ships. In order to identify and manage their own ships in a unified manner, different shipping companies usually set ship name signs or other types of signs on the outer plating or stern plate of the ship.

[0003] The existing construction method for installing the ship weld mark is to first mark the positioning on the ship plate, then paste the plastic or paper lettering with a 1:1 printing scale onto the ship plate according to the positioning requirements, and then outline the mark on the ship plate by manually tapping and connecting the lines. Welding is then carried out along the outline to obtain the weld mark.

[0004] However, the above construction methods have many drawbacks. First, when performing manual welding, welders need to wear welding masks to avoid strong arc light stimulation, which limits their welding field of vision. This not only makes manual operation unstable, causing the weld to easily deviate from the outline, but also requires welders to constantly remove the welding mask to check, resulting in uneven manual welds, a large number of joints, and a huge amount of grinding work. Second, there is a lot of pre-welding preparation work, such as printing marks and outlining the outline. Third, the above welding operations are generally carried out after the hull assembly is completed, involving welding operations in various positions, high-altitude operations, and poor safety. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention discloses a method and system for welding ship weld markings, which improves the welding effect and speed of weld markings and reduces labor costs.

[0006] To achieve the above objectives, the present invention discloses a method for welding ship weld bead markings, comprising:

[0007] Based on the appearance parameters of the logo and the welding position of the logo on the ship, the welding area of ​​the logo on the ship is obtained, and the origin corresponding to the welding area is marked.

[0008] Obtain the stroke range of a single welding operation of the welding machine, and divide the mark pattern according to the stroke range to generate several sub-mark patterns, and generate the position coordinates corresponding to each sub-mark pattern according to the origin;

[0009] Obtain the geometric state of the welding area, and generate the welding direction corresponding to each sub-marker pattern based on the geometric state;

[0010] The welding instructions corresponding to each sub-marker pattern are generated according to the welding direction, and the welding machine is controlled to weld each sub-marker pattern sequentially on the welding area of ​​the ship according to the welding instructions and the position coordinates, thereby completing the welding of the marker pattern.

[0011] This invention discloses a method for welding ship weld markers. When welding the marker pattern, the welding area on the ship is first determined based on the appearance parameters and welding position of the marker pattern, ensuring accurate welding of the marker pattern to the correct area on the ship. Further, after forming the welding area, the origin coordinates of the welding area are determined so that the position coordinates of each subsequently generated sub-marker pattern can be accurately pieced together to form the final marker pattern, ensuring welding precision. When generating each sub-marker pattern, the stroke range of a single welding operation is used to divide the marker pattern. This process ensures that the welding machine does not stop midway during the welding of each sub-marker pattern, thus avoiding uneven welding and wasted welding time, thereby improving the smoothness and speed of welding. After determining each sub-marker pattern and its corresponding position coordinates, the welding sequence of each sub-marker pattern is determined according to the geometric state of the marker pattern, thereby reducing the number of welding joints and improving the smoothness and speed of welding. Finally, based on the welding direction and position coordinates of each sub-marker pattern, a welding instruction corresponding to each sub-marker pattern is generated. The welding machine is controlled according to the welding instruction to perform welding of the marker pattern, completing the automatic welding of the marker pattern, reducing the labor cost of welding and increasing the welding speed.

[0012] As a preferred example, obtaining the welding area of ​​the logo pattern on the ship based on the appearance parameter information of the logo pattern and the welding position of the logo pattern on the ship includes:

[0013] The appearance parameter information of the logo pattern is obtained, and the welding area of ​​the logo pattern on the ship is determined by a preset CAD software based on the appearance parameter information and the welding position; wherein, the appearance parameter information includes the length and width information of the logo pattern.

[0014] This invention utilizes the CAD software to simulate and determine the welding area based on the appearance of the pattern and its welding position on the ship. This avoids the need for manual determination of the welding area, reducing labor costs, while ensuring the accuracy of welding during automatic welding.

[0015] As a preferred example, the step of splitting the sign pattern according to the travel range to generate several sub-sign patterns includes:

[0016] Obtain the outline of the logo pattern, compare the range of the outline with the travel range, and determine whether to split the logo pattern;

[0017] When the range of the contour line is greater than the travel range, the turning points and continuous line segments of the contour line are collected, and the contour line is split according to the turning points, the continuous line segments and the travel range to obtain the sub-marker pattern corresponding to each sub-contour line; wherein, the contour line is split at the turning points, not split on the continuous line segments, and the range of each sub-contour line is less than or equal to the travel range.

[0018] This invention splits the sub-outlines based on the contour lines, and splits at turning points while not splitting on continuous line segments to ensure the aesthetics of the welded and assembled sub-marks. The range of the sub-outline obtained by each split is less than or equal to the travel range to ensure that the welding of the sub-marks does not stop and improves the smoothness of the welding.

[0019] As a preferred example, generating the position coordinates corresponding to each sub-marker pattern based on the origin includes:

[0020] Establish a coordinate system corresponding to the welding area based on the origin, and mark several vertices corresponding to each sub-marker pattern;

[0021] Calculate the vertex coordinates of each of the plurality of vertices in the coordinate system, and generate the position coordinates of each sub-marker pattern on the welding area based on the vertex coordinates.

[0022] This invention establishes a coordinate system with the origin of the welding area and generates the position coordinates of each sub-marker pattern in the welding area, ensuring that the sub-marker patterns can be perfectly assembled into the marker pattern when welded according to the position coordinates, thereby improving the welding accuracy.

[0023] As a preferred example, the process of obtaining the geometric state of the welding area and adjusting the welding direction of each sub-marker pattern according to the geometric state includes:

[0024] Based on the geometric state, the position state of each sub-marker pattern when it is welded in the welding area is obtained;

[0025] When the position state corresponding to the sub-marker pattern is planar during welding, the welding direction of each sub-marker pattern is adjusted according to the preset minimum empty travel principle;

[0026] When the position of the sub-marker pattern is vertical during welding, the welding direction of the sub-marker pattern is adjusted according to the welding principle of welding from top to bottom.

[0027] The present invention takes into account that the position of the sub-marker pattern welded on the ship may be planar or vertical. Therefore, the welding direction of each sub-marker pattern is adjusted according to the position to ensure the smoothness of the welding.

[0028] As a preferred example, the step of generating the welding instructions corresponding to each sub-marker pattern based on the welding parameters includes:

[0029] The outline of each sub-marker pattern is input into a preset conversion software, and welding instructions for each sub-marker pattern are generated by combining the welding direction corresponding to each sub-marker pattern.

[0030] This invention generates welding instructions corresponding to each sub-marker pattern, which are used to control the welding machine to perform automatic welding, avoiding manual welding and improving the welding speed and smoothness.

[0031] As a preferred example, the step of controlling the welding machine to sequentially weld each sub-marker pattern on the welding area of ​​the ship according to the welding command and the position coordinates includes:

[0032] The position coordinates of the origin and each sub-marker pattern are sequentially marked on the plate corresponding to the welding area to form a mark point corresponding to each sub-marker pattern.

[0033] The welding instructions corresponding to each sub-marker pattern are sequentially input into the welding machine, and the welding machine is moved according to the position coordinates of the sub-coordinate pattern corresponding to each welding instruction so that the tip of the welding wire of the welding machine is on the mark point of the sub-coordinate pattern;

[0034] When the tip of the welding wire is determined to be on the marked point, the welding machine is started according to the welding command to weld each sub-mark pattern, thus completing the welding of the mark pattern.

[0035] This invention sequentially imports the welding instructions of the sub-marker pattern into the welding machine. When the sub-marker instruction is activated in the welding machine, the position coordinates of the sub-marker pattern are first determined, and then the welding machine is moved so that the tip of the welding wire is on the corresponding mark point in the welding area. In this way, the position coordinates on the system and the mark point in the welding area are positioned and corresponded, which can realize the positioning welding of the welding instruction in the welding area and improve the welding accuracy.

[0036] On the other hand, the present invention discloses a ship weld marking welding system, including an area division module, a pattern splitting module, a geometric determination module and a marking welding module;

[0037] The region division module is used to obtain the welding area of ​​the logo pattern on the ship based on the appearance parameter information of the logo pattern and the welding position of the logo pattern on the ship, and to mark the origin corresponding to the welding area;

[0038] The pattern splitting module is used to obtain the stroke range of a single welding operation of the welding machine, and to split the mark pattern according to the stroke range to generate several sub-mark patterns, and to generate the position coordinates corresponding to each sub-mark pattern according to the origin.

[0039] The geometric determination module is used to obtain the geometric state of the welding area and generate the welding direction corresponding to each sub-marker pattern according to the geometric state;

[0040] The marking welding module is used to generate welding instructions corresponding to each sub-marking pattern according to the welding direction, and to control the welding machine to sequentially weld each sub-marking pattern on the welding area of ​​the ship according to the welding instructions and the position coordinates, thereby completing the welding of the marking pattern.

[0041] This invention discloses a welding system for ship weld markings. When welding marking patterns, the system first determines the welding area on the ship based on the appearance parameters and welding position of the marking pattern, ensuring accurate welding of the marking pattern to the correct area. Furthermore, after forming the welding area, the system determines the origin coordinates of the welding area. This origin coordinates are then used to determine the position coordinates of each subsequently generated sub-marking pattern, ensuring that each generated position coordinate accurately assembles into the final marking pattern, guaranteeing welding precision. When generating each sub-marking pattern, the system uses the stroke range of a single welding pass to delineate the marking pattern. This process ensures that the welding machine does not stop midway during the welding of each sub-mark pattern, thus avoiding uneven welding and wasted welding time, thereby improving the smoothness and speed of welding. After determining each sub-mark pattern and its corresponding position coordinates, the welding sequence of each sub-mark pattern is determined according to the geometric state of the mark pattern, thereby reducing the number of welding joints and improving the smoothness and speed of welding. Finally, based on the welding sequence and position coordinates of each sub-mark pattern, a welding instruction corresponding to each sub-mark pattern is generated. The welding machine is controlled according to the welding instruction to perform welding of the mark pattern, completing the automatic welding of the mark pattern, reducing the labor cost of welding and increasing the welding speed.

[0042] As a preferred example, the pattern splitting module further includes a splitting determination unit and a coordinate construction unit;

[0043] The splitting determination unit is used to obtain the outline of the logo pattern and compare the range of the outline with the travel range to determine whether to split the logo pattern; when the range of the outline is greater than the travel range, the turning points and continuous line segments of the outline are collected, and the outline is split according to the turning points, the continuous line segments and the travel range to obtain the sub-logo pattern corresponding to each sub-outline; wherein, the outline is split at the turning points, not split on the continuous line segments, and the range of each sub-outline is less than or equal to the travel range;

[0044] The coordinate building unit is used to establish a coordinate system corresponding to the welding area based on the origin, and to mark several vertices corresponding to each sub-marker pattern; calculate the vertex coordinates of each vertex in the coordinate system, and generate the position coordinates of each sub-marker pattern on the welding area based on the vertex coordinates.

[0045] This invention splits the sub-marks based on their outlines, specifically at turning points, while avoiding splitting on continuous line segments to ensure the aesthetic appeal of the welded sub-marks. The range of each sub-outline obtained from the split is less than or equal to the travel range, ensuring uninterrupted welding and improving weld smoothness. Furthermore, a coordinate system is established with the origin of the welding area, generating position coordinates for each sub-mark pattern within that area. This ensures that the sub-mark patterns can be perfectly assembled into the final mark pattern when welded according to these position coordinates, thus improving welding accuracy.

[0046] As a preferred example, the geometry determination module includes a state acquisition unit, a sequence adjustment unit, and a direction adjustment unit;

[0047] The state acquisition unit is used to acquire the position state of each sub-marker pattern when it is welded in the welding area, based on the geometric state.

[0048] The direction adjustment unit is used to adjust the welding direction of each sub-marker pattern according to the preset minimum empty travel principle when the position state corresponding to the sub-marker pattern is a plane during welding; and to adjust the welding direction of the sub-marker pattern according to the welding principle of welding from top to bottom when the position state corresponding to the sub-marker pattern is a vertical plane during welding.

[0049] The present invention takes into account that the position of the sub-marker pattern welded on the ship may be planar or vertical. Therefore, the welding direction of each sub-marker pattern is adjusted according to the position to ensure the smoothness of the welding. Attached Figure Description

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0059] Example 1

[0060] This embodiment discloses a welding method for ship weld bead markings. For the specific implementation process of the welding method, please refer to [reference needed]. Figure 1 The process mainly includes steps 101 to 104, which mainly include:

[0061] Step 101: Based on the appearance parameter information of the logo pattern and the welding position of the logo pattern on the ship, obtain the welding area of ​​the logo pattern on the ship, and mark the origin corresponding to the welding area.

[0062] In this embodiment, the step mainly includes: obtaining the appearance parameter information of the logo pattern, and determining the welding area of ​​the logo pattern on the ship using preset CAD software based on the appearance parameter information and the welding position; wherein, the appearance parameter information includes the length and width information of the logo pattern.

[0063] In this embodiment, the step utilizes the CAD software to simulate and determine the welding area based on the appearance of the pattern and the welding position on the ship. This avoids manually determining the welding area, reducing labor costs, and ensures the accuracy of welding during automatic welding.

[0064] Step 102: Obtain the stroke range of a single welding operation of the welding machine, and divide the mark pattern according to the stroke range to generate several sub-mark patterns, and generate the position coordinates corresponding to each sub-mark pattern according to the origin.

[0065] In this embodiment, the step mainly includes: obtaining the outline of the logo pattern, comparing the range of the outline with the travel range, and determining whether to split the logo pattern; when the range of the outline is greater than the travel range, collecting the turning points and continuous line segments of the outline, and splitting the outline according to the turning points, the continuous line segments, and the travel range to obtain the sub-logo pattern corresponding to each sub-outline; wherein, the outline is split at the turning points, not split on the continuous line segments, and the range of each sub-outline is less than or equal to the travel range.

[0066] Simultaneously, a coordinate system corresponding to the welding area is established based on the origin, and several vertices corresponding to each sub-marker pattern are marked; the vertex coordinates of each vertex in the coordinate system are calculated, and the position coordinates of each sub-marker pattern on the welding area are generated based on the vertex coordinates.

[0067] In this embodiment, the step involves splitting the sub-outline based on the contour line, specifically at turning points. Splitting is not performed on continuous line segments to ensure the aesthetic appeal of the welded sub-markers. The range of each sub-outline obtained from the split is less than or equal to the travel range to ensure uninterrupted welding of the sub-markers, improving welding smoothness. Simultaneously, a coordinate system is established with the origin of the welding area, generating the position coordinates of each sub-marker pattern within the welding area. This ensures that the sub-marker patterns can be perfectly assembled into the final mark pattern when welded according to these position coordinates, improving welding accuracy.

[0068] Step 103: Obtain the geometric state of the welding area, and generate the welding direction corresponding to each sub-marker pattern based on the geometric state.

[0069] In this embodiment, the step mainly includes: obtaining the position state of each sub-marker pattern when welding in the welding area according to the geometric state; when the position state corresponding to the sub-marker pattern during welding is a plane, adjusting the welding direction of each sub-marker pattern according to the preset minimum empty travel principle; when the position state corresponding to the sub-marker pattern during welding is a vertical surface, adjusting the welding direction of the sub-marker pattern according to the welding principle of welding from top to bottom.

[0070] In this embodiment, this step takes into account that the position of the sub-marker pattern welded on the ship may be either planar or vertical. Therefore, the welding direction of each sub-marker pattern is adjusted according to the position to ensure the smoothness of the welding.

[0071] Step 104: Generate welding instructions corresponding to each sub-marker pattern according to the welding direction, and control the welding machine to sequentially weld each sub-marker pattern on the welding area of ​​the ship according to the welding instructions and the position coordinates, thereby completing the welding of the marker patterns.

[0072] In this embodiment, the step mainly includes: inputting the outline of each sub-marker pattern into a preset conversion software, and generating a welding instruction corresponding to each sub-marker pattern by combining the welding direction corresponding to each sub-marker pattern.

[0073] Then, the origin and the position coordinates of each sub-marker pattern are sequentially marked on the plate corresponding to the welding area, forming a mark point corresponding to each sub-marker pattern; the welding command corresponding to each sub-marker pattern is sequentially input into the welding machine, and the welding machine is moved according to the position coordinates of the sub-marker pattern corresponding to each welding command so that the tip of the welding wire is on the mark point of the sub-marker pattern; when it is determined that the tip of the welding wire is on the mark point, the welding machine is started according to the welding command to weld each sub-marker pattern, thus completing the welding of the marker pattern.

[0074] In this embodiment, this step generates welding instructions corresponding to each sub-marker pattern, which are used to control the welding machine to perform automatic welding, avoiding manual welding and improving the welding speed and smoothness. The welding instructions of the sub-marker patterns are sequentially imported into the welding machine. When the sub-marker instructions are opened in the welding machine, the position coordinates of the sub-marker pattern are first determined, and then the welding machine is moved so that the tip of the welding wire is on the mark point corresponding to the welding area. In this way, the position coordinates on the system and the mark point of the welding area are positioned and corresponded, which can realize the positioning welding of the welding instructions in the welding area and improve the welding accuracy.

[0075] On the other hand, this embodiment also provides a ship weld bead marking welding system, the specific structural composition of which can be found in the following reference. Figure 2 It mainly includes a region division module 201, a pattern splitting module 202, a geometric determination module 203, and a mark welding module 204.

[0076] The region division module 201 is used to obtain the welding area of ​​the logo pattern on the ship based on the appearance parameter information of the logo pattern and the welding position of the logo pattern on the ship, and to mark the origin corresponding to the welding area.

[0077] The pattern splitting module 202 is used to obtain the stroke range of a single welding operation of the welding machine, and split the mark pattern according to the stroke range to generate several sub-mark patterns, and generate the position coordinates corresponding to each sub-mark pattern according to the origin.

[0078] The geometry determination module 203 is used to obtain the geometric state of the welding area and generate the welding direction corresponding to each sub-marker pattern according to the geometric state.

[0079] The mark welding module 204 is used to generate welding instructions corresponding to each sub-mark pattern according to the welding direction, and control the welding machine to weld each sub-mark pattern sequentially on the welding area of ​​the ship according to the welding instructions and the position coordinates, thereby completing the welding of the mark pattern.

[0080] In this embodiment, the pattern splitting module 202 further includes a splitting determination unit and a coordinate construction unit.

[0081] The splitting determination unit is used to obtain the outline of the logo pattern and compare the range of the outline with the travel range to determine whether to split the logo pattern; when the range of the outline is greater than the travel range, the turning points and continuous line segments of the outline are collected, and the outline is split according to the turning points, the continuous line segments and the travel range to obtain the sub-logo pattern corresponding to each sub-outline; wherein, the outline is split at the turning points, not split on the continuous line segments, and the range of each sub-outline is less than or equal to the travel range.

[0082] The coordinate building unit is used to establish a coordinate system corresponding to the welding area based on the origin, and to mark several vertices corresponding to each sub-marker pattern; calculate the vertex coordinates of each vertex in the coordinate system, and generate the position coordinates of each sub-marker pattern on the welding area based on the vertex coordinates.

[0083] In this embodiment, the geometry determination module 203 includes a state acquisition unit and a direction adjustment unit.

[0084] The state acquisition unit is used to acquire the position state of each sub-marker pattern when it is welded in the welding area, based on the geometric state.

[0085] The direction adjustment unit is used to adjust the welding sequence of each sub-marker pattern according to the preset minimum empty travel principle when the position state corresponding to the sub-marker pattern is planar during welding; and to adjust the welding direction of the sub-marker pattern according to the welding principle of welding from top to bottom when the position state corresponding to the sub-marker pattern is vertical during welding.

[0086] This embodiment discloses a method and system for welding ship weld markings. When welding the marking pattern, the welding area on the ship is first determined based on the appearance parameters and welding position of the marking pattern, ensuring accurate welding of the marking pattern to the correct area on the ship. Further, after forming the welding area, the origin coordinates of the welding area are determined so that the position coordinates of each subsequently generated sub-marking pattern can be accurately pieced together to form the marking pattern, ensuring welding precision. When generating each sub-marking pattern, the stroke range of a single welding operation is used to refine the marking pattern. The process involves dividing the process into rows to prevent welding machine downtime during the welding of each sub-marker pattern, thus avoiding uneven welding and wasted welding time. This improves the smoothness and speed of the welding process. After determining each sub-marker pattern and its corresponding position coordinates, the welding direction of each sub-marker pattern is determined based on its geometric state. This reduces the number of weld joints and improves the smoothness and speed of the welding process. Finally, based on the welding direction and position coordinates of each sub-marker pattern, a welding instruction is generated for each sub-marker pattern. The welding machine is then controlled according to the welding instruction to perform the welding of the marker pattern, completing the automatic welding of the marker pattern. This reduces the labor cost of welding and increases the welding speed.

[0087] Example 2

[0088] In a specific implementation, this embodiment provides a method for welding ship weld bead markings. The detailed implementation process of this method is described in [reference needed]. Figure 3 It mainly includes steps 301 to 305, the steps being:

[0089] Step 301: In the CAD software, determine the welding area of ​​the logo pattern and the origin corresponding to the welding area based on the length and width of the logo pattern and the welding position of the logo pattern on the ship.

[0090] In this embodiment, the main steps are: obtaining the CAD drawing of the completed logo pattern; determining the forming area, i.e. the welding area, of the logo pattern on the ship using CAD software based on the CAD drawing and the determined welding position of the logo pattern on the ship; and marking an origin point 0 on the logo pattern or the welding area for positioning the logo pattern.

[0091] Step 302: Decompose the outline of the mark pattern according to the single stroke range of the welding machine to obtain several sub-mark patterns, and determine the position coordinates of each sub-mark pattern according to the origin.

[0092] In this embodiment, the main steps are: obtaining the outline of the logo pattern, comparing the range of the outline with the stroke range of the welding machine used to weld the logo pattern, and determining whether to split the logo pattern.

[0093] Specifically, this embodiment uses a portable automatic welding machine, which functions similarly to a digital cutting machine for welding logo patterns. The portable automatic welding machine has a longitudinal track and a horizontal arm, and can control the welding torch (cutting torch) to move along the longitudinal track and the horizontal arm according to the welding instructions (similar to cutting instructions), thereby controlling the welding torch to weld the logo pattern.

[0094] In this embodiment, the determination of whether to split the logo pattern is based on the stroke range of the welding machine. The basis for splitting is that the outline of the sub-logo pattern does not exceed the stroke range of the welding machine. It is also best to split at the turning point of the logo outline, and it is best not to break the split on continuous line segments to ensure that the logo is aesthetically pleasing after the sub-logo patterns are spliced ​​together, and a certain amount of coordinate error is allowed.

[0095] Specifically, refer to Figure 4 To divide the mark according to the maximum stroke range of the automatic welding process, sub-marker 1 and sub-marker 2 are obtained. When the mark pattern is divided into several sub-marker patterns, two points O1, X1(Y1), O2, and X2(Y2) are marked at the vertices of sub-marker 1, 2, ... patterns, i.e., the bottom left and bottom right (or top left) corners, respectively. (Refer to...) Figure 4 For coordinate labeling of the decomposed markers, please refer to [reference needed]. Figure 5 At the same time, a unified coordinate system is established with the origin O, and the position coordinates of O1, X1(Y1), O2, and X2(Y2) in the coordinate system are marked.

[0096] Step 303: Determine the position state of each sub-marker pattern based on the geometric state of the welding area, and input the outline of each sub-marker pattern and the position state into the conversion software to generate the welding instruction corresponding to each sub-marker pattern.

[0097] In this embodiment, the main steps are as follows: Based on the geometric state, obtain the positional state of each sub-marker pattern when it is welded in the welding area, i.e., obtain the positional state of the welding area corresponding to each sub-marker pattern when it is welded. When the sub-marker pattern is on a plane during welding, adjust the welding direction of each sub-marker pattern according to a preset minimum idle travel principle. When the positional state of the sub-marker pattern is on a vertical surface during welding, readjust the welding direction of part of the contour to ensure that all welds in the vertical welding direction are welded from top to bottom. The welding direction when the mark is on a plane or vertical surface can be referenced... Figure 6 ,like Figure 6 As shown, the welding directions of the plane and the elevation are different.

[0098] When determining the welding sequence and welding direction corresponding to each sub-marker pattern, the outline of each sub-marker pattern is input into the conversion software to generate welding instructions for each sub-marker pattern.

[0099] Step 304: Remove impurities from the welding area and mark the position coordinates of the origin and each sub-marker pattern on the plate in the welding area of ​​the marking pattern to form several marking points.

[0100] In this embodiment, the main step is to use mechanical grinding to clean the welding area of ​​rust, moisture, oil, and other impurities. On the welding area of ​​the marking pattern, the positions of point O and the On and Xn (Yn) positions of each sub-marker are marked on the plate according to coordinates. Simultaneously, the sub-marker patterns are written above the marked points in the correct direction. No 1:1 outlining is required; this is merely for confirming the work. Point O is the origin of the marking area, which corresponds to the plate to be welded; the plate is a single piece.

[0101] Step 305: Input the welding instructions into the welding machine in sequence. According to the position coordinates and welding instructions corresponding to each sub-mark pattern, control the welding machine to weld each sub-mark pattern to complete the welding of the mark pattern.

[0102] In this embodiment, the main steps are as follows: The welding instructions corresponding to each sub-marker pattern are sequentially input into the welding machine. Specifically, the welding instructions 1, 2, 3… for sub-marker patterns 1, 2, 3… are sequentially imported into the portable automatic welding machine. When sub-marker instruction 1 is activated in the portable automatic welding machine, the portable automatic welding machine is moved according to the position coordinates of the sub-marker pattern corresponding to welding instruction 1, so that the tip of the welding wire is on the marked point of the sub-marker pattern. Specifically, the position of point O1 of the sub-marker is first determined on the portable automatic welding machine, and then the portable automatic welding machine is moved so that the tip of the welding wire is on the marked point of the forming area O1. This aligns the positioning of O1 on the portable automatic welding machine with the forming area O1. When the tip of the welding wire is confirmed to be on the marked point, the welding machine is started according to the welding instruction to weld each sub-marker pattern, completing the welding of the marker pattern. Specifically, after confirming O1, the positions of X1 (Y1) are aligned, thus achieving the positioning alignment of instruction 1 in the forming area. Welding is then started, completing the welding of sub-marker 1. Sub-marks 2, 3... Complete the welding operation of the mark pattern by following the above steps.

[0112] A welding method for ship weld beads logo provided in this embodiment first cuts the logo pattern into several sub - logo patterns, and then converts them into sub - logo welding instructions through software. At the same time, position the lower left corner and lower right corner (or upper left corner) of the sub - logo pattern on the logo, and mark the coordinates in the logo formation area. After importing the welding instructions into the automatic welding equipment, open them, make the instructions on the system correspond to the marked coordinates one by one, and start welding. Complete the welding of each sub - logo in turn, and the automatic welding of the logo can be realized. On the one hand, there is no need to print the logo pattern in a 1:1 ratio, nor is it necessary to manually punch and connect lines in the logo formation area to outline the logo on the ship plate. Only several coordinate points need to be positioned, saving a large amount of pre - welding preparation work and reducing the construction difficulty. On the other hand, using automatic welding instead of manual welding, the weld beads are smooth, improving the aesthetic degree of the logo formation, reducing the number of joints, reducing the amount of post - welding repair and grinding, and improving work efficiency.
