Welding diodes are designed for medium and high frequency welding equipment and optimized for high current rectifiers. The on-state voltage is very low and the output current is high.
ABB is selling both normal housed and housing-less welding diodes. The latter is becoming more and more important in high current welding applications for joining of high refractory materials.
