[0042] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0043] Example 1

[0044] A method for automatically constructing hull welds, such as Figure 1 As shown, the method includes:

[0045] Step 10: Generate configuration files, which include welding position configuration files, welding foot height configuration files, and welding default value configuration files;

[0046] Step 11: Store the configuration file in the directory specified by the environment variable corresponding to the ship.

[0047] In this embodiment, step 10 specifically includes:

[0048] At least one of a welding type, a limit range of a weld rotation angle and a weld inclination angle corresponding to different welding types, and a calculation rule of a welding position is defined to generate a welding position configuration file.

[0049] Specifically, user-defined welding positions are based on, for example, standard Z3003-1963, "Definition of welding positions." This standard specifies how to calculate the rotation and inclination angles of the weld, described in the local coordinate system of the assembly. With these angles, it is possible to establish rules for calculating the basic welding position.

[0050] A weld position configuration file is a plain text file containing a single statement (POSITION) that can be repeated any number of times. However, the order of the input files is important because the system will check the rules in that order until it finds the weld position. For example, the file might be named weldPosition.def and must be placed in the directory specified by the SB_SHIP environment variable. The format is as follows, with the <> parts filled in according to your needs.

[0051] POSITION,<pos name> / WELD_TYPE=<weld type>

[0052] / DESCRIPTION=<user description>

[0053] / MIN_ROT=<minimum rotation angle>

[0054] / MAX_ROT=<maximum rotation angle>

[0055] / MIN_INCL=<minimum inclination angle>

[0056] / MAX_INCL=<maximum inclination angle>

[0057] in<pos name> It is a string showing the welding position, with a maximum of 26 characters.<weld type> is the type of welding, which can be "fillet" or "butt". MIN_ROT, MAX_ROT, MIN_INCL and MAX_INCL define the limits of rotation angle and tilt angle respectively. For example Figure 2 shown.

[0058] At least one of a welding type, welding parts corresponding to different welding types, a thickness limit of the welding part, and a grade limit is defined to generate a weld leg height profile.

[0059] Specifically, the weld leg height can be calculated in two different ways: it can be done using an input file that defines some simple rules, or it can be done using an execution unit.

[0060] The input file for weld leg height is an ordinary text file with only one statement (LEGLENGTH) which can be repeated any number of times. The file name is weldLegLength.def and must be placed in the directory specified by the SB_SHIP environment variable. The format is as follows. The <> part is filled in according to the actual situation.

[0061] LEGLENGTH,<leg length> / WELD_TYPE=<weld type>

[0062] / PART1_THICK=<thickness 1>

[0063] / PART2_THICK=<thickness 2>

[0064] / PART1_QUAL=<quality 1>

[0065] / PART2_QUAL=<quality 2>

[0066] in<leg length> Weld leg height;<weld type> The type of weld, which can be "fillet" or "butt";<thickness 1> The thickness of the first part. If the value is -1, the thickness will not be checked;<thickness 2> The thickness of the second part. If the value is -1, the thickness will not be checked;<quality 1> The grade of the first part. If the value is *, the thickness will not be checked;<quality 2> The grade of the second part. If the value is *, the thickness will not be checked; for example Figure 3 shown.

[0067] Define at least one of the triggering conditions for weld automatic construction, weld screening conditions, welding type default values, weld data calculation execution conditions, and weld report triggering conditions to generate a welding default value configuration file.

[0068] Specifically, the welding defaults input file is a plain text file with a single statement for each default parameter. The order of the input file is irrelevant. The file is named weldDefaults.def and must be placed in the directory specified by the SB_SHIP environment variable. The format is as follows, with the <> parts filled in as needed.

[0069] ADD_RETURN_WELD, <yes separate no>;

[0070] If this default setting is set to "Yes" or "Separate", return welds (i.e. short welds along the thickness of the end of the part) will be created automatically. In the former case, the welds will be connected into one weld, while in the latter case, the welds will remain separate.

[0071] MINIMUM_WELD_LENGTH,<min weld length> ; All welds shorter than <minimum weld length> will be deleted.

[0072] MIXED_WELD_TYPE,<mixed weld type> ; In some cases, the welds on each side of a part may be different. If this default value is given, <Mixed Weld Type> will be used as the weld type for weld joints.

[0073] WELD_TYPE_TOLERANCE,<weld tolerance> ; If the angle to the plate is less than <weld tolerance>, the weld type will be a butt weld, otherwise it will be a fillet weld.

[0074] CALCULATE_LEGLENGTH, <yes no>; If this default setting is "Yes, leg length will be calculated.

[0075] CALCULATE_POSITION, <yes no>; If this default setting is "Yes, the position will be calculated.

[0076] CALCULATE_SUSPENSION, <yes no>If this default setting is "Yes, the calculation will be paused.

[0077] REMOVE_FULL_SUSPENSION, <yes no>; If this default setting is "Yes", completely hanging welds will be removed.

[0078] CREATE_WELD_REPORT, <yes no>If this default setting is Yes, a welding report will be created automatically. Figure 4 shown.

[0079] Step 20: Obtain the hull model;

[0080] Step 30: Identify the hull model to obtain weld data, where the weld data includes joint information of at least one weld joint and weld information corresponding to each weld joint;

[0081] Among them, such as Figure 5 As shown, step 30 specifically includes:

[0082] Step 301: Select a node to be created in the hull model; the node to be created includes any one of a segment node, a large group node, a medium group node, and a small group node;

[0083] Step 302: Determine the weld detection range based on the node to be created;

[0084] Step 303: Detect any two welded parts in the detection range to obtain a weld joint by corner or butt joint, and obtain the joint information of the weld joint. Figure 6 , the joint information includes one or more of a welding joint number, a first welding part name, a second welding part name, a weld type, and a weld length;

[0085] Step 304: Obtain two welds based on each weld joint and obtain weld information of the welds, see Figure 7 The weld information includes one or more of weld name, welding position, weld leg height, weld length, first weld part groove code, first weld part thickness, second weld part groove code and second weld part thickness.

[0086] Therefore, see Figure 8 , and assembled the relationship diagram of WeldTable (weld table), WeldedJoint (weld joint), and Weld (weld).

[0087] Step 40: Generate a weld model of the ship hull based on the configuration file and the weld data, so as to perform ship hull welding based on the weld model.

[0088] Step 50: Generate an extraction instruction; the extraction instruction includes a node path corresponding to the target weld detection range;

[0089] Step 60: Generate a weld information list corresponding to the target weld detection range according to the extraction instruction and the weld model.

[0090] Specifically, the extraction instructions may include the need for batch input of welding plans, through a welding plan batch program such as (sg011.exe), whose input file is a normal text file. This language has only one statement and can be given multiple times. The <> part is filled in according to actual needs. The file format is as follows.

[0091] ASSEMBLY,<assembly name>

[0092] / CALC_WELD / ROBOT_CTRL / WELD_REPORT;

[0093] If the given assembly <assembly name> ends with an asterisk *, CALC_WELD / ROBOT_CTRL / WELD_REPORT will also be generated for all subassemblies, from top to bottom. It should be noted that the equipment name is the node path within the target weld inspection range, such as the specific path of the segment-large group-medium group-small group to which it belongs.

[0094] If CALC_WELD is given, weld calculations will be performed.

[0095] If ROBOT_CTRL is given, generation of the robot control file will be performed.

[0096] If WELD_REPORT is given, a weld report will be created by Vitesse, an example is shown below:

[0097] ASSEMBLY'-525-G9000-S9BL1A' / CALC WELD / ROBOT CTRL;

[0098] ASSEMBLY,'-525*' / WELD_REPORT;

[0099] The output weld information list is as follows: Figure 9 shown.

[0100] The above-mentioned hull weld automatic construction method of this embodiment can be implemented based on Tribon software. Open the WeldPlanning module of Tribon (a computer software integration system that assists ship design and construction), locate the node where the weld model needs to be created in the Production assembly node, and locate it to any segment, large group, medium group, or small group. Then right-click the mouse to pop up the following dialog box: Figure 10 The menu shown is shown in the figure. Detect Welds detects welds by searching all subassemblies and immediately starting the weld calculation for each assembly within the calculation limit box. These boxes are used to minimize the range of parts / part connections to be checked.

[0101] Detect All Welds (Top-Down) detects all welds (top-down). It performs a recursive weld calculation through the specified nodes in the assembly tree. It starts the weld calculation immediately by retrieving all sub-assemblies below the selected assembly. Then it performs the calculation like "Detect Welds", first for all sub-assemblies and then for the selected assembly. Using recursive functions will save users a lot of time.

[0102] In the above implementation, the creation of the assembled weld model can be completed by clicking "Detect Welds" or "Detect All Welds (Top-Down)".

[0103] This embodiment proposes an automated hull weld construction method to extract weld data based on the weld model, breaking down data statistical silos and improving refined management. After completing a single configuration file, weld creation and weld leg calculation are automatically and rapidly completed based on rules. This method rapidly extracts segmented or grouped weld data, providing data and support for welding material procurement, labor time calculation, and chemical plan compilation, improving the efficiency and accuracy of data statistics and enhancing information technology development capabilities.
