SPW Welding Machines

Projection welding, often abbreviated as SPW (Spot Projection Welding), is a specialized welding process used in metal fabrication and manufacturing. This process is primarily used to join two or more pieces of metal together by creating a series of spot welds at predetermined points along the seam or joint. Projection welding is a resistance welding process, which means it relies on the resistance of the materials to electric current flow to generate heat and create welds. The weld is formed at specific, pre-designed projection points on one of the workpieces.
