What is 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.

Features of resistance welder

It is used for welding of electronic components and car electronics.
The welding power supplies available are AC type, capacitor discharge type, inverter type, transistor type and a unique hybrid (DC+inverter) type which is most suitable for battery tab welding.

Application examples

  • Fusing welding of winding wire of small motors used in automobiles or mobile phones.
  • Insulated wire welding of electronic components, such as resistor, capacitor, coil, transformer and IC card.
  • Resistance welding of solar battery, lamp, connector, switch and battery tab.
  • Resistance welding of ECU, EFI, air bag and other car electronic items.
  • Resistance welding of various sensors, such as printed wiring board, gas sensor, temperature sensor, magnetic sensor, pressure sensor, strain sensor, ultrasonic sensor and acceleration sensor.
