AI Technical Summary

Technical Problem

Existing handheld welding heads are difficult to precisely control the angle and distance when welding small-diameter metal pipes, which affects the welding quality. At the same time, the welding heads are easily damaged when not in use.

Method used

A welding head including a rotating steering arm and a steering assembly is designed, with the angle defined by a guide rail and a locking device, and a protective sleeve to protect the welding head from collisions.

Benefits of technology

It enables precise control of welding angle and distance for small-diameter metal pipes, improving welding quality and protecting the welding head from damage.
