Power Electronics Devices Of Resistance Welder

Resistance welding is to press the work?piece to be welded between the two electrodes by high current?penetrated. It’s a method that the resistance heat generated by the current flowing through the work?piece contact surface and the adjacent area is used to heat it to molten or plastic state to bond?the?metal. The main resistance welding is?in the form of spot welding, seam welding, projection welding and butt welding.

The development of modern?industries such as automotives, vessels, planes, and high-speed railways,?require the medium and high frequency ultra-high current resistance welding machines?and the ultra-high current diode?work as the vital component is extremely required.

With constant innovation and strong research ability, Runau Electronics had developed the ultra-high current diode?featured in optimized high current density,?very low on-state voltage and very low?thermal resistance?which can parallel connect directly, thin silicon wafer, low?threshold voltage, small slope resistance, high junction temperature, gold or?platinum diffusion?combined with electron irradiation?to control minority life, apply?low anode concentration?and dual-bases zone?technology?to achieve the purpose of high frequency soft and fast recovery. The diode packaged in housed?and housing-less. The ultra-high current welding diode can be adopted in resistance welder with frequency from 1KHz to 5 KHz.
