Features

Resistance welding is a type of welding method that uses resistance heat as the energy source, including electroslag welding that uses slag resistance heat as the energy source and resistance welding that uses solid resistance heat as the energy source.

Resistance welding is generally a welding method in which the workpiece is placed under a certain electrode pressure and the contact surface between the two workpieces is melted by the resistance heat generated when the current passes through the workpiece to realize the connection. Generally, a larger current is used. To prevent arcing on the contact surfaces and to forge the weld metal, pressure must always be applied during the welding process. When performing this type of resistance welding, the surface quality of the welded workpiece is of paramount importance for obtaining stable welding quality. Therefore, the contact surface between the electrode and the workpiece and between the workpiece and the workpiece must be cleaned before welding.
