AI Technical Summary

Technical Problem

During the maintenance of the hydraulic support top beam, it is difficult to accurately control the angle of the welding torch with a handheld welding machine, resulting in inconsistent weld depth, unstable operation, and easy to cause safety accidents.

Method used

A welding device comprising a support structure, a clamping structure, and a suspension assembly was designed. The welding machine angle is adjusted by casters and telescopic rods, the welding machine posture is fixed by the clamping structure, and the welding machine position is stabilized by the suspension assembly, ensuring welding consistency and safety.

Benefits of technology

This achieves stability and consistency in the welding process, avoids uneven weld depth, improves operational safety and efficiency, and reduces the risks associated with hand-held shaking.
