Description

Technical Field

[0002] With the acceleration of industrialization, welding, as an important connection process, occupies a pivotal position in the manufacturing industry. Traditional manual welding has problems such as low efficiency, unstable quality, high labor intensity and poor working environment safety.

[0003] When welding parts in traditional welding methods, it is basically done manually using a welding head, holding the workpiece manually, and then using a foot switch to complete the welding of the workpiece. Since the workpiece has four welding points, manual welding requires four weldings, and the double-column welding machine and the welding points need to be accurately positioned.

[0004] At present, such equipment and methods are manually operated, resulting in low operating efficiency and lack of automation. Secondly, the operating safety risks are high. The workpiece is held in hand and started by foot switch, and there are safety risks in the coordinated operation of hands and feet.
