What Is High Frequency Welding

High-frequency welding is a common solid phase resistance welding method in the machinery industry. The principle of this method is as follows: high frequency current will produce resistance heat through steel, the heat generated can heat the surface of the steel to be welded to melt or close to the plastic state, and then apply the top forging force to realize the welding of steel.
