Projection Welding

Projection welding is a resistance welding technique where localized welds are formed at predetermined points by embossing projections on one of the metal pieces. When current and pressure are applied, these raised areas concentrate heat, allowing multiple welds to be made simultaneously. This method ensures precise weld placement, reduced deformation, and strong joints, making it ideal for fasteners, brackets, and components in the automotive and electronics industries. Projection Welding is a type of resistance welding where small projections or embossed points on one workpiece localize the welding heat, allowing for precise, high-strength welds. When pressure and current are

applied, the projections collapse and form a weld at defined points. This process is ideal for welding fasteners (like nuts, bolts, and studs) to metal sheets, and is frequently used in the automotive, electrical, and appliance industries. It offers high consistency, minimal material distortion, and excellent automation compatibility.
