Furthermore, manual welding is greatly affected by human factors; different welders have varying welding experience, operating habits, and skill levels. Even when welding the same material, differences in welding techniques can lead to inconsistent weld quality, making it difficult to guarantee the stability of welded product quality. Summary of the Invention

[0005] Preferably, each row of wheels has at least two wheels.

[0006] Preferably, the clutch has two states: closed and disengaged. When the clutch is closed, the motor drives the drive shaft to rotate, thereby dragging the traveling wheels. When the clutch is disengaged, the welding device can be manually pushed.

Its features include: a drive shaft 3 is arranged between the two rows of traveling wheels 1; a support frame 4 is mounted on the drive shaft 3; the support frame 4 is fixedly connected to the drive shaft 3 by connecting bolts 2, which are arranged perpendicular to the axis of the drive shaft 3 to limit the displacement of the support frame 4 relative to the drive shaft 3; a crossbeam 5 is connected to the upper end of the support frame 4 by fastening bolts A12; a connecting plate 7 is mounted on the crossbeam 5 and fixed to the crossbeam 5 by fastening bolts B6; a connecting disc 9 is connected to the connecting plate 7 by pins 8; and a welding torch 10, which can rotate at any angle, is mounted on the connecting disc 9. The walking control mechanism 11 includes a motor 111, a turbine 112, a clutch 113, a handle 114, and a worm gear 115. The clutch 113 is connected to the handle 114, the worm gear 115 is connected to the turbine 112, the turbine 112 is connected to the motor 111, and the two ends of the worm gear 115 are respectively connected to two rows of walking wheels 1 to transmit power to the walking wheels 1 and drive them to rotate.

[0017] In this preferred embodiment, each row of walking wheels 1 is provided with at least 2 wheels.

[0018] In this preferred embodiment, the clutch 113 has two states: closed and disengaged. When the clutch 113 is closed, the motor 111 drives the transmission shaft 3 to rotate, thereby dragging the traveling wheel 1. When the clutch 113 is disengaged, the welding device can be manually pushed. In this preferred embodiment, the rotation speed of the motor 111 is adjustable, and the walking speed of the walking wheel 1 is controlled by changing the rotation speed of the motor 111.

[0019] In this preferred embodiment, when the fastening bolt A12 is loose, the horizontal frame 5 adjusts its position along the height direction of the vertical frame 4, and when the fastening bolt A12 is tightened, the horizontal frame 5 and the vertical frame 4 are relatively fixed.

[0020] In this preferred embodiment, when the fastening bolt B6 is loosened, the connecting plate 7 slides along the length of the crossbeam 5, and when the fastening bolt B6 is tightened, the connecting plate 7 and the crossbeam 5 are fixed.

[0021] In this preferred embodiment, the connecting disc 9 is provided with an oblong hole, and the connecting plate 7 is provided with an elliptical hole. By adjusting the relative positions of the oblong hole on the connecting disc 9 and the elliptical hole on the connecting plate 7, the distance between the welding torch 10 and the workpiece can be adjusted.

[0022] In practice, the workpiece to be welded is fixed on the welding platform, and the welding start point and end point are marked according to the welding path of the workpiece to ensure that the workpiece is flat and without deviation; the operating handle 114 puts the clutch 113 in the "disengaged" state, and the welding device is manually pushed to the vicinity of the welding start point; If it is necessary to fine-tune the distance between the welding torch 10 and the workpiece, loosen the fastening bolt B6 between the connecting disc 9 and the connecting plate 7. Using the fit clearance between the elongated hole on the connecting disc 9 and the elliptical hole on the connecting plate 7, push the connecting disc 9 to move along the extension direction of the hole. At the same time, loosen the fastening bolt B6 and push the connecting plate 7 to slide left and right along the length of the crossbeam 5 until the nozzle of the welding torch 10 is precisely aligned with the welding start point. Then tighten the fastening bolt B6 to lock the position of the connecting plate 7 and ensure that the position of the welding torch 10 is stable.

[0023] If the vertical height of welding torch 10 needs to be adjusted, loosen the fastening bolt A12, push the horizontal frame 5 to move up and down along the height direction of the vertical frame 4, and tighten the fastening bolt A12 after reaching the target height to fix the horizontal frame 5. After the welding torch position is adjusted, the operating handle 114 switches the clutch 113 to the "closed" state, so that the transmission link between the motor 111 and the traveling wheel 1 is connected; press the welding start switch of the welding torch 10, and at the same time start the motor 111. At this time, the welding torch 10 generates an electric arc and feeds wire. The welding device moves at a constant speed along the set welding path and starts automatic welding. After welding is completed, the operating handle 114 switches the clutch 113 to the "disengaged" state, and the welding device is manually pushed away from the welding area and moved to the designated storage location; the spatter in the nozzle of the welding torch (10) is cleaned, and the main welding power switch is turned off; the problems of unstable welding quality and low work efficiency of traditional manual CO2 gas shielded welding are solved.
