Inspecting projection welded nuts. Creating multiple projections allow simultaneous welding of multiple weld spots. When projection welding high impact will damage the projection before welding and result in poor projection welds even when all other settings are correct.
Measurement and inspection after welding should check both the surface and inside of welds.
Embossed projection welding uses projections worked on the base material to concentrate current flow on the projections. Projection welding has fewer variables that affect the resistance welding process as compared to spot welding. Projection welding is a form of resistance welding which uses pressure and electrical current to join two or more metal parts that have been designed to meet at one or more specific points with the maximum amount of contact.
