Description

Technical Field

[0001] The invention relates to the field of steel pipe welding, and in particular to an automated welding device for steel pipe production and a production system thereof. Background Art

[0002] Steel pipe is a common industrial material, widely used in construction, petroleum, chemical industry, machinery manufacturing and other fields.

[0003] Steel pipes often need to be welded during the production process. Before welding, the welding position of the steel pipe needs to be grooved. The groove processing should be mechanically carried out to reduce the defects in the heat-affected zone. Therefore, the cross-section of the steel pipe needs to be grooved in advance before welding. The steel pipe needs to be repositioned for welding after the groove processing is completed. If the steel pipe is not welded in time after the groove processing, the groove position of the steel pipe will be re-contaminated or rusted, thereby affecting the welding quality of the steel pipe. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an automated welding equipment and a production system for steel pipe production.

[0005] In a first aspect, the present invention provides an automated welding device for steel pipe production, comprising a bracket, and further comprising:

[0006] The annular frame is rotatably mounted inside a circular hole penetrating through the side wall of the bracket through a first rotation drive assembly;

[0007] Two vertical movable frames are installed inside the annular frame through a position adjustment component. The position adjustment component drives the vertical movable frames to perform planar movement adjustment. The outer rings of the two vertical movable frames are sleeved with a rotating movable frame.

[0008] A fixed box, fixed on the side wall of the rotating and moving frame;

[0009] A groove processing assembly is installed on the side wall of the fixed box, and is used to automatically identify the cross-sectional shape of the end of the steel pipe and perform groove processing on the end of the steel pipe before welding according to the cross-sectional shape;

[0010] A welding assembly is installed on the bracket and is used to drive the welding assembly to move along a shape track for welding according to the cross-sectional shape of the steel pipe end portion identified by the groove processing assembly;

[0011] A switching drive assembly is installed at the bottom of the bracket, and is used to drive the bracket to move, thereby driving the groove processing assembly and the welding assembly to perform switching processing;

[0012] The staff will position and install the steel pipes to be welded on both sides of the bracket through the feeding assembly, and then control the feeding assembly to push the steel pipes to move toward the bracket, so that the two ends of the two steel pipes to be welded contact the groove processing assembly. After the groove processing assembly is started, it automatically identifies the cross-sectional shape of the steel pipe, so that the groove processing assembly can move along the cross-sectional edge path of the steel pipe to perform groove processing on the cross section of the steel pipe, thereby automatically realizing the groove processing of the cross section of the steel pipe. After the cross-sectional groove processing of the steel pipe is completed, the feeding assembly pushes the two steel pipes away from each other for a distance, and then controls the switching drive assembly to start. After the switching drive assembly is started, it drives the bracket to move, so that after the bracket moves, it drives the groove processing assembly and the welding assembly to move, so that the groove processing assembly is far away. The welding assembly is away from the steel pipe and close to the steel pipe, the welding assembly moves to the position of the groove processing assembly, and then the feeding assembly pushes the two steel pipes closer to each other, so that the ends of the two steel pipes to be welded fit together and the grooves on the two steel pipes overlap, and then the welding assembly is controlled to start, and the welding assembly copies the moving path of the groove processing assembly to weld the steel pipe, so that after the groove processing of the steel pipe, the welding of the steel pipe is seamlessly connected, so that the groove processed by the groove processing assembly can be used for welding of the steel pipe later, which is beneficial to avoid the process of transferring the steel pipe to welding after the groove processing is completed, and the transfer process after the steel pipe is stored is interfered, causing the groove position of the steel pipe to be contaminated or rusted, thereby affecting the welding stability of the steel pipe.

[0013] Preferably, the groove processing assembly comprises:

[0014] A movable box is slidably mounted on the bottom of the fixed box through a reversing drive mechanism, and a slope is provided on one side of the movable box;

[0015] A grinding disc is rotatably mounted on the inclined plane, and a grinding drive assembly for driving the grinding disc to rotate is installed inside the moving box;

[0016] A straight tube is fixed on a side wall of the fixed box facing away from the rotating movable frame, and a plurality of notches are formed on the side wall of the straight tube in a circumferential array;

[0017] A plurality of pressure sensors are arranged corresponding to the notches one by one and fixed inside the notches;

[0018] The straight pipe is placed inside the steel pipe, and the moving box drives the grinding disc to be located outside the steel pipe. When the steel pipe approaches the grinding disc, the outer wall edge of the steel pipe gradually contacts the grinding disc. Since the grinding disc is inclined along the inclined surface, the closer the steel pipe is to the grinding disc, the larger the groove formed by processing the edge of the steel pipe. Therefore, the size of the groove processed by the steel pipe can be controlled by controlling the movement drive of the feeding assembly to the steel pipe, which is conducive to controlling the size of the groove.

[0019] The grinding drive assembly drives the grinding disc to rotate, and the grinding disc grinds the outer surface edge of the steel pipe to form a groove. Then, the rotating moving frame drives the moving box to move through the fixed box, thereby driving the grinding disc to move to perform groove processing.

[0020] The pressure sensor on the straight pipe is squeezed by the inner wall of the steel pipe. If the steel pipe is a circular cross-section, the pressure sensor on the straight pipe remains unchanged. At this time, the first rotating drive component is controlled to drive the annular frame to rotate, so that the grinding disc rotates along the outer wall of the steel pipe to perform groove processing on the outer wall edge of the steel pipe. If the steel pipe is a square cross-section, when the straight pipe moves along one side edge of the steel pipe, one of the pressure sensors on the straight pipe is continuously pressurized. When the straight pipe moves to the edge of the steel pipe, a pressurized pressure sensor is added to the straight pipe. At this time, the position adjustment component is controlled to drive the rotating movable frame to move in the direction of the straight pipe away from the continuously pressurized rotating movable frame. At the same time, the reversing drive mechanism is controlled to start. When the pressure sensor with increased pressure is located in the clockwise direction of the rotating movable frame that is continuously under pressure, the rotating movable frame is driven to rotate 90° in the clockwise direction. When the pressure sensor with increased pressure is located in the counterclockwise direction of the rotating movable frame that is continuously under pressure, the rotating movable frame is driven to rotate 90° in the counterclockwise direction. The rotating movable frame is then continued to be moved to perform bevel processing on the other side of the steel pipe, so that the grinding disc can perform bevel processing along the edge of the steel pipe, and automatically turn to the other side for processing after the edge processing on one side is completed, thereby realizing automatic recognition and processing of the edge of the steel pipe.

[0021] Preferably, the welding assembly comprises:

[0022] A second annular frame is rotatably mounted inside a through slot provided on the side wall of the bracket via a second rotation drive assembly;

[0023] A welding gun, mounted on the inner wall of the second annular frame via a telescopic rod;

[0024] The second rotation drive assembly drives the second annular frame to rotate, and the telescopic rod can drive the welding gun to move along the direction of the telescopic rod. Through the movement control of the telescopic rod and the rotation control of the second annular frame, the welding gun can be driven to move to any position of the inner circle of the second annular frame, so that the welding gun can move along the moving trajectory of the groove processing assembly, and the edge of the steel pipe is welded by the welding gun.

[0025] Preferably, it also includes two feeding assemblies, which are symmetrically arranged on both sides of the bracket and are used to drive the steel pipe to move toward the bracket for groove processing and welding;

[0026] The feeding assembly comprises:

[0027] Two lifting platforms are aligned and placed on the same side of the bracket;

[0028] Two groups of second fixing frames, two of the second fixing frames form a group, one group of the second fixing frames corresponds to one lifting platform, and the second fixing frames in the same group are symmetrically fixed to the top of the lifting platform;

[0029] Four cylinders are respectively fixed on the side walls of the four second fixing frames;

[0030] Two groups of clamping frames, two of the clamping frames form one group, the clamping frames are respectively fixed to the ends of the telescopic rods of the four cylinders, and the clamping frames in the same group are located between the second fixing frames in the same group;

[0031] The lifting end of the lifting platform can adjust the height of the steel pipe, and the translation end of the lifting platform can adjust the lifting end horizontally, thereby driving the steel pipe to move and adjust. The lifting end and the translation end of the lifting platform are driven by the lifting push rod and the translation push rod respectively, which are mature existing technologies and will not be repeated here. The steel pipe can be adjusted to the center position corresponding to the center position of the annular frame, thereby facilitating the groove processing of the steel pipe. The second fixed frame can install the cylinder, so that after the cylinder is started, it pushes the clamping frame to move to clamp and position the steel pipe, which is beneficial to maintain the stability of the steel pipe during the processing.

[0032] Preferably, the reversing drive mechanism comprises:

[0033] A fourth motor is fixed inside the fixing box, and a first gear is fixed to an output shaft of the fourth motor;

[0034] A rack fixed to the bottom of the moving box, the rack meshing with the first gear;

[0035] A fifth motor is fixed inside the fixed box, and an output shaft of the fifth motor passes through the rotating movable frame and is fixed with a second gear;

[0036] a third gear, fixed on a side wall of the vertical movable frame, the third gear meshing with the second gear;

[0037] After the fourth motor is started, it can drive the first gear to rotate, and the first gear drives the rack meshing with it to move, so that the rack drives the moving box to move, thereby driving the moving box to move back and forth a short distance after turning, which is beneficial to fully beveling the edge of the steel pipe. After the fifth motor is started, it can drive the second gear to rotate through the output shaft, and the second gear meshes with the third gear, so that the second gear rolls around the third gear, thereby driving the rotating moving frame to rotate around the vertical moving frame, thereby realizing the rotation drive of the rotating moving frame.

[0038] In a second aspect, a production system method of an automated welding device for steel pipe production is provided, wherein a control unit is installed on the bracket, and the pressure sensor includes four corresponding to the four positions of right, lower and left in the clockwise rotation direction, and the production system includes the following steps:

[0039] A1. The control unit obtains pressure information and pressure change information from the pressure sensor, wherein the pressure information includes upper pressure information, lower pressure information, right pressure information and left pressure information corresponding to the four pressure sensors;

[0040] A2. The control unit generates drive control information and steering control information according to the pressure information and the pressure change information, wherein the drive control information includes upward control information, downward control information, leftward control information and rightward control information, and the steering control information includes clockwise steering information and counterclockwise steering information;

[0041] A3. The control unit sends the drive control information to the groove processing component and the position adjustment component to control the groove processing component and the position adjustment component to cooperate in the groove processing reversal;

The upper pressure sensor generates upper pressure information after being pressurized, the lower pressure sensor generates lower pressure information after being pressurized, the right pressure sensor generates right pressure information after being pressurized, and the left pressure information after being pressurized. The pressure sensor sends the generated pressure information to the control unit. The pressure sensor generates pressure change information when the pressure it receives increases. For example, originally only the upper pressure sensor in the pressure sensor is pressurized to generate upper pressure information, and now a right pressure sensor is added to be pressurized to generate right pressure information. At this time, the pressure sensor generates pressure change information at the same time, and then the pressure sensor sends the pressure change information to the control unit. After obtaining the pressure information and the pressure change information, the control unit generates drive control information and steering control information according to the pressure information and the pressure change information, and sends the drive control information and steering control information to the groove processing component and the position adjustment component to control the groove processing component and the position adjustment component to cooperate in groove processing reversing.

[0043] Preferably, the step A2 specifically includes:

[0044] The pressure change information includes constant pressure information and newly added pressure information, wherein the constant pressure information is the pressure information before the pressure sensor generates the pressure change information, and the newly added pressure information is the pressure information newly added after the pressure sensor generates the pressure change information;

[0047] The control unit acquires the newly added pressure information from the pressure change information;

[0048] When the pressure sensor corresponding to the newly added pressure information is located in the clockwise direction of the pressure sensor corresponding to the constant pressure information, the control unit generates clockwise turning information; when the pressure sensor corresponding to the newly added pressure information is located in the counterclockwise direction of the pressure sensor corresponding to the constant pressure information, the control unit generates counterclockwise turning information;

[0049] The pressure change information includes constant pressure information and newly added pressure information. The constant pressure information is the pressure information received before the pressure sensor generates the pressure change information, and the newly added pressure information is the pressure information received after the pressure sensor generates the pressure change information. For example, originally only the upper pressure sensor in the pressure sensor was pressurized to generate the upper pressure information, and now a right pressure sensor is added to be pressurized to generate the right pressure information. At this time, the constant pressure information is the upper pressure information, and the newly added pressure information is the right pressure information. At this time, the control unit generates a downward movement control information according to the constant pressure information (the upper pressure information at this time). Information, and at the same time, the newly added pressure information (the right pressure information at this time) is in the clockwise direction of the constant pressure information (the upper pressure information at this time), then the control unit generates clockwise steering information at this time, and vice versa, so that the control unit generates drive control information (the downward control information at this time) and steering control information (the clockwise steering information at this time) to control the movement and adjustment of the groove processing component and the position adjustment component, so as to realize the groove processing component automatically identifying the trajectory of the steel pipe cross section, thereby automatically moving along the trajectory of the edge of the steel pipe cross section for processing, which is beneficial to improve the convenience and processing efficiency of the steel pipe groove processing.

[0050] Preferably, it also includes:

[0051] The control unit obtains the moving path information from the groove processing assembly;

[0052] The control unit generates welding path control information according to the moving path information;

[0053] The control unit sends the welding path control information to the welding assembly to control the welding assembly to install the path of the moving path information for mobile welding;

[0054] When the groove processing component automatically identifies the trajectory of the steel pipe and performs groove processing along the trajectory, the groove processing component records and generates the moving trajectory to generate the moving path information, and the groove processing component sends the moving path information to the control unit. After obtaining the moving path information, the control unit generates welding path control information according to the moving path information, and sends the welding path control information to the welding component to control the welding component to move according to the moving trajectory of the moving path information to perform welding processing on the steel pipe.

[0055] Preferably, a visual sensor is fixedly mounted on the inclined surface, and the control unit includes a user end and further includes:

[0056] The control unit acquires image information from the visual sensor;

[0057] The control unit obtains the notch comparison information from the user terminal;

[0058] The control unit identifies the notch information in the picture information according to the notch comparison information, and when the control unit identifies the notch information, the control unit generates selected information, wherein the selected information includes position information of the notch information;

[0059] The control unit generates welding control information according to the selected information, and the welding control information is used to control the welding assembly to stop welding at the position information corresponding to the selected information;

[0060] The control unit sends the welding control information to the welding assembly;

[0061] The visual sensor takes a picture and obtains the picture, and sends the picture to the control unit in the form of picture information. The staff inputs the notch comparison information from the user end, and the user end sends the notch comparison information to the control unit, so that the control unit obtains the picture information and the notch comparison information. The control unit compares the picture information with the notch comparison information, identifies the notch information in the picture information, and then generates selected information. The selected information includes the position information of the notch information. Then the control unit generates welding control information according to the selected information, and sends the welding control information to the welding assembly to control the welding assembly to perform stop welding at the position information corresponding to the selected information, so that the notch position at the edge of the steel pipe can be briefly stopped for welding, thereby improving the stability of the steel pipe welding.

[0062] Preferably, it also includes:

[0063] The control unit acquires steel pipe cross-section information from the user terminal, wherein the steel pipe cross-section information includes square pipe information and round pipe information;

[0064] When the steel pipe cross-section information is the square pipe information, the control unit does not perform switching control, and when the steel pipe cross-section information is the round pipe information, the control unit generates round pipe switching control information;

[0065] The control unit sends the round pipe switching control information to the first rotation drive assembly to control the first rotation drive assembly to drive the annular frame to rotate to perform round steel pipe groove processing;

[0066] The staff inputs the steel pipe cross-section information of the steel pipe from the user end, inputs the round pipe information when the steel pipe is a round pipe, and inputs the square pipe information when the steel pipe is a square pipe. The user end sends the steel pipe cross-section information to the control unit. After the control unit obtains the steel pipe cross-section information, if the steel pipe cross-section information is square pipe information, the control unit does not perform switching control. When the steel pipe cross-section information is the round pipe information, the control unit generates round pipe switching control information and sends the round pipe switching control information to the first rotating drive component to control the first rotating drive component to drive the annular frame to rotate to perform round steel pipe groove processing.

DETAILED DESCRIPTION

[0083] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0084] like Figures 2 to 12 An automated welding device for steel pipe production shown includes a bracket 1 and also includes:

[0085] The annular frame 3 is rotatably mounted inside a circular hole penetrating through the side wall of the bracket 1 through a first rotation driving assembly;

[0086] Two vertical moving frames 402 are installed inside the annular frame 3 through a position adjustment component. The position adjustment component drives the vertical moving frames 402 to perform planar movement adjustment. The outer rings of the two vertical moving frames 402 are both sleeved with a rotating moving frame 403.

[0087] The fixed box 7 is fixed on the side wall of the rotating movable frame 403;

[0088] The groove processing assembly is installed on the side wall of the fixed box 7, and is used to automatically identify the cross-sectional shape of the end of the steel pipe and perform groove processing on the end of the steel pipe before welding according to the cross-sectional shape;

[0089] The welding assembly is installed on the bracket 1 and is used to drive the welding assembly to move along the shape track for welding according to the cross-sectional shape of the steel pipe end portion identified by the groove processing assembly;

[0090] A switching drive assembly is installed at the bottom of the bracket 1 and is used to drive the bracket 1 to move, thereby driving the groove processing assembly and the welding assembly to perform switching processing;

[0091] Steel pipes often need to be welded during the production process. Before welding, the welding position needs to be grooved. The groove processing should be done by mechanical methods to reduce the defects in the heat-affected zone. Therefore, the cross section of the steel pipe needs to be grooved in advance before welding. The steel pipe needs to be repositioned for welding after the groove processing is completed. If the steel pipe is not welded in time after the groove processing, the groove position of the steel pipe will be re-contaminated or rusted, thereby affecting the welding quality of the steel pipe;

[0092] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: the staff positions and installs the steel pipes to be welded on both sides of the bracket 1 through the feeding assembly, and then controls the feeding assembly to push the steel pipe to move toward the bracket 1, so that the two ends of the two steel pipes to be welded contact the groove processing assembly. After the groove processing assembly is started, it automatically identifies the cross-sectional shape of the steel pipe, so that the groove processing assembly can move along the cross-sectional edge path of the steel pipe to perform groove processing on the cross section of the steel pipe, thereby automatically realizing the groove processing of the cross section of the steel pipe. After the cross-sectional groove processing of the steel pipe is completed, the feeding assembly pushes the two steel pipes away from each other for a distance, and then controls the switching drive assembly to start. After the switching drive assembly is started, it drives the bracket 1 to move, so that after the bracket 1 moves, it drives the groove processing assembly and the welding The connecting assembly moves so that the groove processing assembly is away from the steel pipe and the welding assembly is close to the steel pipe, the welding assembly moves to the position of the groove processing assembly, and then the feeding assembly pushes the two steel pipes closer to each other, so that the ends of the two steel pipes to be welded fit together, and the grooves on the two steel pipes overlap, and then the welding assembly is controlled to start, and the welding assembly copies the moving path of the groove processing assembly to weld the steel pipe, so that after the groove processing of the steel pipe, the welding of the steel pipe is seamlessly connected, so that the groove processed by the groove processing assembly can be used for welding of the steel pipe later, which is conducive to avoiding the process of transferring the steel pipe to welding after the groove processing is completed, and the interference of the transfer process after the steel pipe is stored, causing the groove position of the steel pipe to be contaminated or rusted, thereby affecting the welding stability of the steel pipe.

[0093] The switch drive components include:

[0094] The threaded bracket 201 is fixed to the bottom of the bracket 1;

[0095] A first fixing frame 202 is disposed on the ground;

[0096] The first motor 203 is fixed inside the first fixing frame 202. The output shaft of the first motor 203 passes through the first fixing frame 202 and is fixed with a first screw rod 204. The first screw rod 204 is threadedly connected to the threaded frame 201.

[0097] After the first motor 203 is started, the output shaft drives the first screw 204 connected thereto to rotate. After the first screw 204 rotates, it drives the threaded frame 201 threadedly connected thereto to move. The threaded frame 201 drives the bracket 1 to move, thereby realizing the movement drive of the bracket 1. By driving the bracket 1, the groove processing component and the welding component are further switched.

[0098] The first rotation drive assembly has the same structure as the second rotation drive assembly;

[0099] The first rotation drive assembly comprises:

[0100] The second motor 303 is fixed to the top of the bracket 1, and the output shaft of the second motor 303 is fixed with a second bevel gear 302;

[0101] The first bevel gear 301 is fixed on the side wall of the annular frame 3, and the second bevel gear 302 is meshed with the first bevel gear 301;

[0102] After the second motor 303 is started, the output shaft drives the second bevel gear 302 connected thereto to rotate, the second bevel gear 302 drives the first bevel gear 301 meshing therewith to rotate, and the first bevel gear 301 drives the annular frame 3 to rotate, thereby driving the annular frame 3;

[0103] It should be noted that the first bevel gear 301 in the second rotation drive assembly is fixed on the side wall of the second annular frame 12 , and the structural principles of the second rotation drive assembly are the same as those of the first rotation drive assembly, which will not be described in detail here.

[0104] The position adjustment components include:

[0105] Two transverse moving frames 401 are symmetrically and transversely slidably mounted on the slide rails fixed on the inner wall of the annular frame 3 through a first screw drive mechanism;

[0106] The two vertical moving frames 402 are symmetrically and vertically slidably installed on the two horizontal moving frames 401 through a second screw drive mechanism;

[0107] The first screw drive mechanism and the second screw drive mechanism are both commonly used screw drive mechanisms, which are mature existing technologies and will not be described in detail here;

[0108] The first screw drive mechanism drives the transverse moving frame 401 to move transversely along the slide rail, and the second screw drive mechanism drives the vertical moving frame 402 to move vertically along the transverse moving frame 401, thereby driving the vertical moving frame 402 to any position on the horizontal plane, so as to facilitate the vertical moving frame 402 to adapt to the cross-section of the steel pipe for moving processing.

[0109] As an optional embodiment, the groove processing assembly includes:

[0110] The movable box 5 is slidably mounted on the bottom of the fixed box 7 through a reversing drive mechanism, and a slope is provided on one side of the movable box 5;

[0111] The grinding disc 6 is rotatably mounted on the inclined plane, and a grinding drive assembly for driving the grinding disc 6 to rotate is installed inside the moving box 5;

[0112] The straight tube 8 is fixed on the side wall of the fixed box 7 facing away from the rotating movable frame 403, and a plurality of notches are formed in a circular array on the side wall of the straight tube 8;

[0113] A plurality of pressure sensors 801 are arranged corresponding to the notches one by one and fixed inside the notches;

[0114] The straight pipe 8 is placed inside the steel pipe, and the moving box 5 drives the grinding disc 6 to be located outside the steel pipe. When the steel pipe approaches the grinding disc 6, the outer wall edge of the steel pipe gradually contacts the grinding disc 6. Since the grinding disc 6 is arranged along the inclined surface, the closer the steel pipe is to the grinding disc 6, the larger the groove formed by processing the edge of the steel pipe. Therefore, the size of the groove processed by the steel pipe can be controlled by controlling the movement drive of the feeding assembly to the steel pipe, which is conducive to controlling the size of the groove.

[0115] The grinding drive assembly drives the grinding disc 6 to rotate, and the grinding disc 6 grinds the outer surface edge of the steel pipe to form a groove. Then, the rotating movable frame 403 drives the movable box 5 to move through the fixed box 7, thereby driving the grinding disc 6 to move and perform groove processing.

[0116] The pressure sensor 801 on the straight tube 8 is squeezed by the inner wall of the steel tube.

[0167] The working principle of the present invention is as follows: the staff positions and installs the steel pipes to be welded on both sides of the bracket 1 through the feeding assembly, and then controls the feeding assembly to push the steel pipes to move toward the bracket 1, so that the two ends of the two steel pipes to be welded contact the groove processing assembly. After the groove processing assembly is started, it automatically identifies the cross-sectional shape of the steel pipe, so that the groove processing assembly can move along the cross-sectional edge path of the steel pipe, and groove the cross section of the steel pipe, thereby automatically realizing the groove processing of the cross section of the steel pipe. After the cross-sectional groove processing of the steel pipe is completed, the feeding assembly pushes the two steel pipes away from each other for a distance, and then controls the switching drive assembly to start. After the switching drive assembly is started, it drives the bracket 1 to move, so that after the bracket 1 moves, it drives the groove processing assembly and the welding assembly to move, so that The groove processing assembly is far away from the steel pipe and the welding assembly is close to the steel pipe. The welding assembly moves to the position of the groove processing assembly, and then the feeding assembly pushes the two steel pipes closer to each other, so that the ends of the two steel pipes to be welded fit together and the grooves on the two steel pipes overlap. Then the welding assembly is controlled to start, and the welding assembly copies the moving path of the groove processing assembly to weld the steel pipe. After the groove processing of the steel pipe, the welding of the steel pipe is seamlessly connected, so that the groove processed by the groove processing assembly can be used for welding of the steel pipe later, which is beneficial to avoid the process of transferring the steel pipe to welding after the groove processing is completed. If the transfer process is disturbed after the steel pipe is stored, the groove position of the steel pipe will be contaminated or rusted, thereby affecting the welding stability of the steel pipe.
