Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a steel structure welding device for building construction. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of steel profiles and plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components are usually connected by welds, bolts, or rivets. Due to their light weight and ease of construction, they are widely used in large factories, stadiums, and high-rise buildings. Steel structures are prone to corrosion, and generally require rust removal, galvanizing, or painting, as well as regular maintenance. During the construction and installation of steel structure buildings, some steel structures need to be pre-welded and spliced ​​on the ground. Existing steel structure welding equipment used in building construction cannot effectively inspect the joints of the steel structures, resulting in welding misalignment and uneven welding.

[0003] Chinese Patent Publication No. CN117066798A discloses a steel structure welding device for building construction, including a base, a portal-shaped fixed seat mounted on the top of the base, a prompter on the side wall of the fixed seat, and a welding component mounted on the top of the fixed seat; movable seats are movably mounted at both ends of the top of the base, and a second through hole is opened on the top of the movable seat, with a rotating housing slidably mounted inside the second through hole, and a pressing mechanism is provided inside the rotating housing; it also includes a driving mechanism. In use, one end of the steel structure to be welded is inserted into the rotating housing, and the steel structure is pressed and fixed by the pressing mechanism. The horizontal position of the movable seat is adjusted by a fourth telescopic component, so that the welding ends of the two steel structures are joined at the bottom of the welding component, facilitating accurate detection of the joining condition of the steel structure welding ends and ensuring the welding effect of the steel structure; however, the following defects still exist in the implementation process:

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Example 1, as Figure 1-2As shown, a steel structure welding device for building construction includes an auxiliary transport component 1. A base assembly 3 is fixedly connected to the lower end of the auxiliary transport component 1. A motor component 2 is provided on the upper left side of the base assembly 3. A clamping mechanism 4 is provided on the upper side of the base assembly 3. The output end of the motor component 2 is connected to the clamping mechanism 4 located on the left side via a belt. A transport assembly 5 is provided in the middle of the base assembly 3. An I-beam 7 is provided on the upper side of the transport assembly 5 and between the two clamping mechanisms 4. A welding mechanism 6 is provided on the upper right side of the base assembly 3 and the lower right side of the transport assembly 5.

[0032] It should be noted that auxiliary transport component 1 consists of a fixed frame, rolling wheels, and a conveyor belt, which is used to assist in the guiding and transporting of the I-beam. Motor component 2 consists of a motor body and a pulley. The specific installation method, circuit connection method, and control method of the motor body in motor component 2 are all conventional designs and are standard design methods used by designers.

[0033] The I-beam 7 is a type of steel structure. Before construction, some I-beams 7 require additional welding of reinforcing bases (i.e., steel plates). First, one end of the I-beam 7 is hoisted onto the auxiliary transport component 1 using external hoisting equipment. The auxiliary transport component 1 allows the I-beam 7 to be smoothly pushed between the two clamping mechanisms 4 and onto the transport group 5. Next, an appropriate amount of steel plate is placed into the welding mechanism 6, and the I-beam 7 is clamped and fixed by the two clamping mechanisms 4. Then, the welding mechanism 6 is operated, and with the cooperation of the base group 3, the steel plate in the welding mechanism 6 is placed onto the bottom wall of the inner cavity of one side of the I-beam 7 and welded. According to the requirements, equidistant welding is performed from the right side of the I-beam 7 to the left side. After welding on one side is completed, with the cooperation of the base group 3, the transport group 5 begins to extend back and forth. After extension is completed, the motor component 2 is started, and with the cooperation of the belt, the two clamping mechanisms 4 drive the I-beam 7... The steel beam 7 rotates 180 degrees, causing the welded side to flip downwards, and welding begins on the other side. After the flip is complete, the transport group 5 retracts with the cooperation of the base group 3, supporting the lower end of the I-beam 7. Then, the welding mechanism 6 is activated to begin equidistant welding from left to right. During this process, the welding mechanism 6 can also grind and remove the weld slag on the already welded side. Finally, after the other side is welded, the transport group 5 extends again, and the motor component 2, in conjunction with the belt, causes the clamping mechanism 4 to rotate the welded I-beam 7 again. The welding mechanism 6 then cleans the weld slag on the other side. After all cleaning is completed, the clamping mechanism 4 releases its grip on the I-beam 7, and with the cooperation of the transport group 5, it is transported out from the right side, completing the entire welding work. The entire process requires no manual welding or hand-holding of the steel plate, saving time and effort. Furthermore, the weld slag can be removed after welding.

[0034] To assist the clamping mechanism 4, the transport assembly 5, and the welding mechanism 6 in completing the welding of the I-beam 7, such as... Figure 3As shown, the base assembly 3 includes a base body 31. The upper end of the base body 31 is provided with a front-to-back symmetrical slide rail 35. The middle of the upper end of the base body 31 is provided with two left-to-right symmetrical slide rails 37. The upper left rear part of the base body 31 is provided with a mounting groove 32. The inner cavity of the mounting groove 32 is rotatably connected to a rotating shaft 34. The left end of the rotating shaft 34 is fixedly connected to a transmission wheel 33, and the right end of the rotating shaft 34 is fixedly connected to a transmission wheel 36. The upper left side of the base body 31 is fixedly connected to the lower end of the auxiliary transport component 1. The upper left rear part of the base body 31 is fixedly connected to the lower end of the motor component 2. The outer surface of the transmission wheel 33 is connected to the output end of the motor component 2 via a belt.

[0035] First, the transmission wheel 33 is composed of two transmission wheels 36, and the transmission wheel 33 is compatible with the pulley in the motor component 2 and connected by a belt. The slide rail 35 is fixedly installed on the front and rear sides of the upper end of the base body 31, so that the welding mechanism 6 can slide left and right on the slide rail 35. The two slide rails 37 are fixedly installed on the left and right sides of the upper end of the base body 31, so that the transport group 5 can extend or retract on the four slide rails 37. By starting the motor component 2, the transmission wheel 33 drives the rotating shaft 34 to rotate in the cavity of the mounting groove 32, which in turn drives the transmission wheel 36 to rotate. Since the transmission wheel 33 and the transmission wheel 36 rotate simultaneously, the clamping mechanism 4 on the left and right sides will operate, and the I-beam 7 will rotate 180 degrees. Through the cooperation between the clamping mechanism 4, the transport group 5 and the welding mechanism 6, the welding work of the I-beam 7 is finally completed.

[0036] Example 2: In order to achieve the purpose of clamping and flipping the I-beam 7, such as... Figure 4 As shown, both clamping mechanisms 4 include limiting brackets 41. Clamping groups 42 are rotatably connected to the inner cavities of both limiting brackets 41. Mounting brackets 44 are fixedly connected to the lower rear side of the outer surfaces of both limiting brackets 41. Gears 45 are rotatably connected to the inner cavities of both mounting brackets 44. Transmission wheels 43 are fixedly connected to the ends of the two gears 45 that are far apart from each other. The outer surfaces of the two gears 45 are respectively meshed with the two clamping groups 42. The lower ends of the two limiting brackets 41 are respectively fixedly connected to the left and right sides of the upper end of the base body 31. The outer surface of the transmission wheel 43 on the left side is connected to the transmission wheel 33 via a belt, and the outer surface of the transmission wheel 43 on the right side is connected to the transmission wheel 36 via a belt.

[0037] First, one end of the I-beam 7 is hoisted onto the auxiliary transport component 1 using external hoisting equipment. The auxiliary transport component 1 allows the I-beam 7 to be smoothly pushed between the two clamping mechanisms 4 and onto the transport assembly 5. Next, the clamping assemblies 42 on both sides clamp and fix the I-beam 7. With the cooperation of the base assembly 3, the welding mechanism 6, and the transport assembly 5, the welding work on one side of the I-beam 7 is completed. When welding is required on the other side, the motor component 2 is started, and with the help of the belt, the transmission wheel 33 drives the rotating shaft. 34 rotates within the mounting slot 32, thereby driving the second transmission wheel 36 to rotate. This causes the first transmission wheel 33 and the second transmission wheel 36 to rotate simultaneously. With the assistance of the belt, the third transmission wheels 43 on both sides rotate. The rotation of the third transmission wheel 43 causes the first gear 45 on both sides to rotate within the two mounting brackets 44 respectively, and drives the clamping assembly 42 to rotate 180 degrees within the limiting bracket 41, thus completing the flipping of the I-beam 7. Ultimately, this achieves the purpose of clamping and flipping the I-beam 7.

[0038] As further explained in Figure 5, both clamping groups 42 include rotating gear rings 421. The inner surfaces of the two rotating gear rings 421 are provided with symmetrical hydraulic cylinders 422. The output ends of the two hydraulic cylinders 422 on the same side are fixedly connected to clamping blocks 423. The outer surfaces of the two clamping blocks 423 on the same side are respectively attached to the upper and lower sides of the outer surface of the I-beam 7 on the same side. The outer surfaces of the two rotating gear rings 421 are respectively rotatably connected to the inner cavities of the two limiting brackets 41. The outer surfaces of the two rotating gear rings 421 are respectively meshed with the outer surfaces of the two gears 45.

[0039] It should be noted that the specific installation method, circuit connection method, and control method of the hydraulic cylinder 422 in this invention are all conventional designs and are standard design methods used by designers.

[0040] When the I-beam 7 is transported to the middle of the two rotating gear rings 421, the four hydraulic cylinders 422 are activated simultaneously, which drives the two clamping blocks 423 on the same side to move closer to each other to a suitable position, so that the two clamping blocks 423 on the left and right sides clamp the I-beam 7 on the left and right sides respectively, thus completing the clamping and fixing of the I-beam 7 and preventing it from moving. When the I-beam 7 needs to be rotated 180 degrees, the gears 45 on the left and right sides rotate, which at the same time drives the rotating gear rings 421 on the left and right sides to rotate 180 degrees in the inner cavity of the limit bracket 41, thus completing the clamping, fixing and placement operation of the I-beam 7.

[0041] Example 3: Based on Examples 1 and 2, this example uses an auxiliary welding mechanism 6 to complete the welding of the I-beam 7, such as... Figure 6 and Figure 7As shown, the transport assembly 5 includes symmetrical side support plates 51 and symmetrical protective shells 591. Two symmetrical sliding sleeves 52 are provided on the lower side of the ends of the two side support plates 51 that are far apart from each other. Several rollers 55 are provided on the upper part of the sides of the two side support plates 51 that are close to each other. The movement of the several rollers 55 on the front and rear sides, which are far apart from each other, passes through the side support plate 51 on the same side and is fixedly connected to a gear 56. The outer surfaces of the several gears 56 on the same side are connected by a chain. A motor 59 is provided on the lower rear end of each of the two side support plates 51. A transmission wheel 58 is fixedly connected to the output end of each of the two motors 59 and the end of the rightmost gear 56 on the front and rear sides that is far apart from each other. The two transmission wheels 58 on the same side are connected by a belt. Symmetrical toothed plates 593 are provided on the lower side of the ends of the two side support plates 51 that are close to each other. Two toothed plates 593 on the same side have their outer surfaces close to each other and are connected to gear 3 592. The inner cavities of the two gear 3 592 are rotatably connected to each other. The lower ends of the two protective shells 591 are fixedly connected to the left and right sides of the upper end of the base body 31. A hydraulic cylinder 2 57 is fixedly connected to the lower side of the middle of the rear end of the front side support plate 51. The lower end of the hydraulic cylinder 2 57 is fixedly connected to the middle of the upper end of the base body 31. A rectangular through groove 53 is opened on the lower side of the two side support plates 51 close to each other. A sliding groove 54 is opened in the middle of the two side support plates 51 close to each other. The inner cavities of the four sliding sleeves 52 on the front side are slidably connected to the front side of the outer surface of the four sliding rails 2 37. The inner cavities of the four sliding sleeves 52 on the rear side are slidably connected to the rear side of the outer surface of the four sliding rails 2 37.

[0042] It should be noted that the specific installation method, circuit connection method, and control method of the hydraulic cylinder 57 and motor 59 in this invention are all conventional designs and are standard design methods used by designers.

[0043] First, the I-beam 7 is clamped and fixed by two clamping groups 42, and the lower front and rear sides of the I-beam 7 are respectively attached to the upper surface of several rollers 55 on the front and rear sides. The connecting plate 61 in the welding mechanism 6 passes through the inner cavity of the rectangular through slots 53 on the front and rear sides and connects to the drive seats 62 on the front and rear sides. The side support plates 51 on the front and rear sides are provided with sliding grooves 54 for installing the grinding group 64 and making sliding connection. When the I-beam 7 needs to be flipped, the second hydraulic cylinder 57 is started first, so that the second hydraulic cylinder 57 drives the side support plate 51 located on the front side to move in the cooperation of the sliding sleeve 52 and the slide rail 2. As the outer surface of 37 moves forward, it drives the toothed plate 593 fixed on the front side support plate 51 to slide forward in the inner cavity of the protective shell 591 and the outer surface of the gear 3 592. This causes the gear 3 592 to rotate in the inner cavity of the protective shell 591, which in turn causes the toothed plate 593 installed on the rear side support plate 51 to slide backward relative to each other. This pushes the rear side support plate 51 to slide backward relative to the outer surface of the slide rail 2 37 under the cooperation of the sliding sleeve 52, so that the front and rear side support plates 51 move away from each other, completing the extension. This ensures that the front and rear side support plates 51 do not affect the rotation of the I-beam 7. As the side support plates 51 move away from each other, the grinding assembly 64 retracts downwards under the action of the sliding groove 54, ensuring that the grinding assembly 64 does not affect the rotation of the I-beam 7. At this time, the rotation of the I-beam 7 is completed through the clamping mechanism 4 in cooperation with the motor component 2, the base assembly 3, and the belt. After rotation, the hydraulic cylinder 57 is activated, and with the cooperation of the sliding sleeve 52, the gear 592, and the toothed plate 593, the two side support plates 51 move closer together to return to their initial positions. Simultaneously, the grinding assembly 64 extends upwards to return to its initial height. Finally, the auxiliary welding mechanism 6 completes the welding of the I-beam 7. After the welding and slag removal of the I-beam 7 are completed, the clamping group 42 releases the clamp on the I-beam 7, and the motors 59 on the front and rear sides are started. With the cooperation of the belt, the drive wheel 58 and the chain, several gears 56 on the front and rear sides rotate simultaneously, thereby driving several rollers 55 on the same side to rotate. Through the rotation of the rollers 55 on the front and rear sides, the I-beam 7 is transported to the right. With the cooperation of the external unloading equipment, the operation of the I-beam 7 being transported out of the device is completed.

[0044] To achieve the purpose of welding and removing weld slag from 7, such as Figure 8 and Figure 9As shown, the welding mechanism 6 includes a connecting plate 61. Two rectangular through slots 53 penetrate the inner cavities of the front and rear sides of the outer surface of the connecting plate 61. A grinding assembly 64 is fixedly connected to the middle of the upper end of the connecting plate 61. Drive seats 62 are fixedly connected to both the front and rear ends of the connecting plate 61. A welding robotic arm 63 is fixedly connected to the upper end of the rear drive seat 62. A feeding platform 68 is fixedly connected to the upper end of the front drive seat 62. A second motor component 69 is fixedly connected to the left side of the middle of the lower end of the feeding platform 68. A first rotating component 691 is provided in the middle of the bottom wall of the inner cavity of the feeding platform 68. The output end of the second motor component 69 is connected to the left side of the outer surface of the first rotating component 691 via a belt. A symmetrical pusher is engaged on the outer surface of the first rotating component 691. A mechanical clamping arm 65 is fixedly connected to the rear side of the upper end of the feeding platform 68. An L-shaped plate 66 is fixedly connected to the middle of the upper end of the feeding platform 68, and the rear side of the L-shaped plate 66 is located directly below the mechanical clamping arm 65. A rotating component 695 is rotatably connected to the inner cavity of the L-shaped plate 66. A threaded slide 694 is provided on the front side of the inner cavity of the L-shaped plate 66 and the front side of the outer surface of the rotating component 695. A spring rotating plate 693 is rotatably connected to the inner cavity of the threaded slide 694. A motor component 692 is fixedly connected to the front side of the middle of the bottom wall of the inner cavity of the feeding platform 68. The output end of the motor component 692 is connected to the front side of the outer surface of the rotating component 695 via a belt. The inner cavities of the two drive seats 62 are slidably connected to the outer surfaces of the two slide rails 35 respectively.

[0045] It should be noted that the drive base 62 is composed of a base, drive motor, controller, sensor, reducer, chain, and other components, which work together to allow the drive base 62 to move left and right on the slide rail 35. Motor components 69 and 692 are both composed of small motors and pulleys. The specific installation methods, circuit connections, and control methods of the small motors in the welding robotic arm 63, mechanical gripper 65, motor components 69 and 692, as well as the drive motor, controller, sensor, and reducer in the drive base 62, are all conventional designs and standard design practices. The welding robotic arm 63 is composed of a base, joints, arm and wrist, welding torch, wire feeding mechanism, control system, and sensor system. These components cooperate to achieve automation and intelligence. The welding operation is efficient and accurate. In addition, the rotating component 691 is composed of a long rod, a pulley, and reciprocating threaded grooves symmetrically opened on the outer surface of the long rod. The rotating component 695 is composed of a reciprocating threaded rod and a pulley. The pulley in the rotating component 691 is connected to the pulley in the motor component 69 by a belt. The pulley in the motor component 692 is connected to the pulley in the rotating component 695 by a belt. The bottom wall of the inner cavity of the feeding table 68 has a groove for installing the rotating component 691. When the rotating component 691 rotates, it can drive the push plates 67 on the left and right sides to move back and forth in the inner cavity of the groove. The mechanical gripper 65 is composed of a base, a horizontal hydraulic telescopic rod, a vertical hydraulic telescopic rod, and a hydraulic claw. It is a conventional design and a common design method for designers. It can complete the gripping of steel plates.

[0046] First, a suitable amount of steel plate is placed into the inner cavity of the feeding platform 68 and clamped between the two push plates 67. When the two clamping groups 42 clamp and fix the I-beam 7 onto the transport group 5, the motor component 692 is started. With the cooperation of the belt, the rotating component 695 rotates in the inner cavity of the L-shaped plate 66. The rotation of the rotating component 695 drives the threaded slide 694 to slide backward in the inner cavity of the L-shaped plate 66, which in turn drives the elastic rotating plate 693 to push the front end of the steel plate located in the middle of the inner cavity of the feeding platform 68, so that the steel plate moves backward in the inner cavity of the feeding platform 68 to the underside of the mechanical clamping arm 65, where it is clamped by the mechanical clamping arm 65. The steel plate is placed in a suitable position on the bottom wall of the inner cavity of the I-beam 7. The connection between the steel plate and the I-beam 7 is welded by the welding robot arm 63. While the mechanical clamping arm 65 holds the steel plate, the second motor component 69 is started. With the help of the belt, the first rotating component 691 rotates, driving the push plates 67 on both sides to push the steel plate in the inner cavity of the feeding table 68 closer to each other and move to a suitable position. The second rotating component 695 then rotates, and the threaded slide 694 drives the elastic rotating plate 693 to move forward. At this time, the elastic rotating plate 693 rotates backward in the inner cavity of the threaded slide 694, along the upper end of the steel plate. When the slide reaches its forwardmost position, the elastic rotating plate 693 rotates forward and becomes perpendicular to the threaded slide block 694. The elastic rotating plate 693 returns to its initial position, and the next push pushes the middle steel plate to the underside of the mechanical clamping arm 65. When a weld is completed, the two drive seats 62 move to the left side of the outer surface of the front and rear slide rails 35 respectively to a suitable distance. At the same time, the connecting plate 61 drives the grinding assembly 64 to move to the left side of the inner cavity of the slide groove 54 with the cooperation of the rectangular through groove 53. This cycle continues until the welding operation on one side of the I-beam 7 is completed. Then, the motor component 2, in cooperation with the base assembly 3 and the belt, flips the I-beam 7. Beforehand, the grinding group 64 is retracted downwards by the transport group 5, so that the height of the grinding group 64 does not affect the flipping of the I-beam 7. After the flipping is completed, the steel plate is placed in the appropriate position of the I-beam 7 by the mechanical clamping arm 65, and welding is performed by the welding robotic arm 63. In addition, by starting the grinding group 64, the welding slag at the welding point on the lower side of the I-beam 7 can be ground and removed, ultimately achieving the purpose of welding the I-beam 7 and removing the welding slag. The welding mechanism 6 not only realizes the automatic feeding of the steel plate to complete the welding, but also removes the welding slag. There is no need for the staff to hold the steel plate by hand during welding, and the welding slag at the welding point does not need to be handled manually.

[0047] To further explain, such as Figure 10As shown, the grinding assembly 64 includes a telescopic support rod 641. Auxiliary support rods 642 are fixedly connected to both the front and rear sides of the outer surface of the telescopic support rod 641. A base plate 648 is fixedly connected to the upper end of the telescopic support rod 641 and the upper ends of the two auxiliary support rods 642. Connecting rods 644 are rotatably connected to both the front and rear sides of the lower end of the base plate 648. Slider blocks 643 are rotatably connected to the sides of the two connecting rods 644 that are far apart from each other. The outer surfaces of the two sliders 643 are slidably connected to the inner cavities of the two sliding grooves 54, respectively. A rotating component 649 is rotatably connected to the middle of the inner cavity of the base plate 648. A sliding seat 646 is provided on the front side of the inner cavity of the base plate 648 and the front side of the outer surface of the rotating component 649. A symmetrical grinding component 647 is provided on the upper end of the sliding seat 646. A motor component 645 is fixedly connected to the front side of the lower end of the base plate 648. The output end of the motor component 645 is connected to the front side of the outer surface of the rotating component 649 via a belt.

[0048] It should be noted that motor component 4 645 consists of a small motor and a pulley, and rotating component 3 649 consists of a reciprocating threaded rod and a pulley. The pulley in motor component 4 645 and the pulley in rotating component 3 649 are connected by a belt. Grinding component 647 consists of a grinding wheel, a housing, and a motor, and they work together to grind and remove the welding slag at the weld joint. The specific installation methods, circuit connections, and control methods of the small motor in motor component 4 645, rotating component 3 649, and the motor in grinding component 647 in this invention are all conventional designs and are standard design methods used by designers.

[0049] In detail, when the I-beam 7 is flipped, the side support plates 51 on the front and rear sides move away from each other. This movement, via the sliding grooves 54 on the front and rear sides, causes the sliders 643 on the same side to move away from each other as well. The movement of the two sliders 643 pulls the connecting rods 644 on the front and rear sides, causing the connecting rods 644 to drive the base plate 648 downwards, compressing the telescopic support rods 641 and auxiliary support rods 642 to a suitable position. This ensures that when the clamping assembly 42 flips the I-beam 7, it will not collide with the grinding component 647, thus unaffecting the flipping of the I-beam 7. After the flipping is complete, the side support plates 51 on the front and rear sides move closer to each other. With the coordinated use of the slide 54 and slider 643, connecting rod 644 and telescopic support rod 641, and auxiliary support rod 642, the base plate 648 moves upward to return to its initial position. Then, the mechanical clamping arm 65 clamps the steel plate and places it on the appropriate position of the I-beam 7. Welding is then performed by the welding mechanical arm 63, with the base plate 648 positioned below the welded steel plate. The starting motor component 645, in conjunction with the belt, causes the rotating component 649 to rotate, driving the sliding seat 646 to slide back and forth within the cavity of the base plate 648. This, in turn, drives the two grinding components 647 to grind the welded areas on the left and right sides of the steel plate. After welding is completed at one point on the welding robot arm 63 and grinding is completed on the lower grinding component 647, the next step is to weld the steel plate and remove the lower welding slag. Hydraulic cylinder 2 57, in conjunction with gear 3 592, gear 3 592, gear plate 593, side support plate 51, and slide groove 54, causes slider 643 and connecting rod 644 to drive base plate 648, compressing telescopic support rod 641 and auxiliary support rod 642. This causes the two grinding components 647 to move downwards and detach from the steel plate after slag removal. Through drive seat 62 and connecting plate 61, the grinding assembly 64 and the supply... The material platform 68 and the telescopic support rod 641 move equidistantly together as needed. During the movement, the sliders 643 on the front and rear sides slide in the inner cavities of the two grinding groups 64 respectively. After moving to the appropriate position, the side support plates 51 on the front and rear sides move closer to each other. With the cooperation of the sliding groove 54, the slider 643 and the connecting rod 644, the base plate 648 moves upward. At the same time, the two grinding components 647 are stuck on both sides of the next steel plate with unremoved welding slag, and grinding and removing the slag and welding the upper steel plate are performed. The automatic feeding and welding of the steel plate is completed, and the welding slag at the welding point can also be removed.
