Induction welding machines facilitate small-dimension tube welding

Patented switching technology on EFD Induction's Weldac induction welding machines now allows the machines to use IGBT transistors at frequencies up to 500 kHz for small-dimension tube welding.

The improvements have led to lower stress and power loss in the transistors and the inverter module across the frequency range used for tube and pipe welding, the company reports.
