Resistance Projection Welding (RPW) ❖ One of metal sheets to be welded, has to be put through a punch press which makes small projection or buttons in the metal sheet
❖ Projection welds are produced at localised points in work pieces help under pressure between suitable electrodes
❖ Welds are made simultaneously

Resistance Projection Welding (RPW)
â?– A resistance welding process in which coalescence occurs at one or more small contact points on parts
â?– Contact points determined by design of parts to be joined .May consist of projections, embossments, or localized intersections of parts
