Basic Knowledge of Sheet Metal Processing - Welding Processing (7)

We will introduce the basic knowledge of sheet metal processing.

"Welding processing" refers to the process of joining two or more metal parts. This page introduces the welding methods implemented at Tsubota Technica, specifically "stud welding" and "projection welding." ○ Stud Welding Studs or bosses are welded onto a flat plate. Specialized equipment is used for the studs, bosses, and welding machine. The welded studs are used to attach components, but due to the small welding area, the strength of the weld is not very high, making it suitable for fixing lighter items such as circuit boards. ○ Projection Welding The edges of sheet metal or the corners of nuts (using horned nuts) are pressed against the base material, and concentrated electrical current is passed through to melt and join them. This is also processed with specialized welding equipment. It can achieve greater strength than stud welding, making it suitable for welding large-diameter nuts that support adjusters or casters. Other processes such as brazing have also been successfully implemented, but they will not be covered here.
