Resistance Welding
Resistance welding is a method in which the welding works are heated by resistance heat generated by sandwiching the welding workpieces with welding electrodes, passing current through them, and the metal is welded while pressurizing the works.A resistance welding machine composed of welding power supply, a weld head and an electrode. The welding power supply controls a welding current,the weld head exerts a pressure on the material to weld and the electrode provides welding current and pressurization force to the part under welding. We have been providing various kinds of welding power supplies and welding heads to meet these requirements.
