Resistance Welding

Projection welding is a form of resistance welding that utilizes projections to concentrate the current and welding force on a small area. This allows for more efficient welding with reduced energy consumption and enhanced weld strength. This welding process offers various competitive advantages as it guarantees high-quality outcomes at a cost-effective rate. 

Spot welding is the most commonly employed form of resistance welding. This method involves passing an electrical current through electrodes attached to two separate metal surfaces pressed together. This process generates heat, which causes the pieces to melt and fuse together, resulting in the formation of spot welds at one or more specific locations. Consequently, this method necessitates a higher amount of current and pressure.

Seam welding is a variant of spot welding, with the primary distinction being that the welding electrodes consist of motor-driven wheels instead of stationary rods. The disc-shaped electrode wheels generate heat, which in turn produces a continuous weld as the parts are fed between them, resulting in a rolling resistance weld or a non-hermetic seam weld.

Butt welding is one of the simplest and adaptable forms of weld joint designs. The type of joint is create by placing two metal pieces end-to-end and subsequently welding them together along the joint. It is crucial to note that in a butt joint, the surfaces of the parts being joined are on the same plane and weld metal remains within the planes of these surfaces. Consequently, the parts are nearly parallel and do not overlap, unlike lap joints.
