Common types of resistance welding are as follows:

● Resistance spot welding: stacked welding materials, connected with the welding power supply with copper electrodes clamped welding part and energized, with the heat generated by resistance (Joule heat) for melting joint welding method.

● Resistance welding projection welding: with resistance welding electrode against the protrusion of unilateral welding material, by focusing the heat on the protrusion, softening the base material, start crimping. As the crimping progresses, the resistance point will increase. At this point, the current density will decrease, the temperature will increase, the resistance will increase, can maintain a state of easy heating, welding.

● Resistance welding roll welding: use the electrode of roll welding wheel to clamp the welding material, rotate the welding wheel at the same time, through resistance heating, continuous welding of the welding material welding method. Linear welding can be carried out to achieve air tightness. Welding does not produce flash at the same time has the advantages of fast welding speed, no use of gas welding cost.

● Resistance butt welding, flash butt welding: alignment of the joint end face, apply pressure and power, relying on the heat generated by resistance (Joule heat) joint welding method.

Application:It is widely used in automobile, aircraft, instrument, home appliance, steel bar used in construction and other industries, with a wide range of materials. However, resistance welding of easily oxidized metals has poor weldability and is mainly used for welding thin plate components with thickness less than 3mm. All kinds of steel, aluminum, magnesium and other non-ferrous metals and their alloys, stainless steel and so on can be welded.
