Projection Welding What Is. While it can be also used to join thinner metal pieces together that tends to be a. Projection welding is one kind of resistance weld where the shape or design of the part is used to make subtle point contacts to concentrate the current during welding.
Projection welding is a resistance welding process that produces coalescence by the heat obtained from the resistance to the flow of the welding current. The electrodes are placed on work piece and current passed between them. This page introduces projection welding a method that adopts resistance welding principles.
The electrodes are flat.
While it can be also used to join thinner metal pieces together that tends to be a. Mostly in almost all applications with various small projections are molded on single parts surfaces which need to weld. One of the main differences between conventional sheet-to-sheet resistance welding and projection welding is that projection welding is a dynamic process involving considerable movement of the upper electrode. Projection welding uses the same equipment as spot welding.
