AI Technical Summary

Technical Problem

Existing handheld laser welding devices have limited field of view and lack effective thermal management in complex curved surface welding conditions, which affects the stability of welding parameters.

Method used

The continuous displacement adjustment of the protective plate is achieved by using a sliding module of the sliding mounting bracket and a spring positioning ball positioning mechanism. It also integrates a composite heat dissipation channel, which dissipates heat through heat dissipation fins and axial flow fan, and exhausts hot air with honeycomb heat dissipation holes.

Benefits of technology

It expands the visible welding area, improves temperature stability, reduces the temperature rise rate of the welding torch, and enhances welding efficiency and safety.
