AI Technical Summary
In existing technologies, welding the side plates of excavator booms requires flipping the sides for welding, which results in low efficiency, easy deformation of the weld, and high cost of custom tooling.
A welding auxiliary device including a base, slide rail, slider, pad, and support plate was designed. Double-sided welding is achieved by setting weld support components and guide grooves. Combined with movable weld support components, it can adapt to side plates of various specifications.
It achieves double-sided welding in one step, improving welding efficiency, avoiding weld deformation, and reducing production costs.
