800KW Solid state high frequency welder — dual function Pipe welding machine set
The solid-state high frequency welding machine uses the German IXYS company IXFN38N100Q2 38A/1000V high-power MOSFET and DSEI 2×61-12B 60A/1200V fast recovery diode to form a series inverter circuit. The inverter device is installed in a bolt crimping method, which is different from the parallel type. The circuit board welding method of the inverter device of the solid-state high-frequency welding machine.

The welding of steel tube, stainless steel tube, aluminum tube, copper tube, H-beam and special section tube.
Solid state high frequency welder is mainly applied to high frequency straight seam tube mill line. The high frequency power supply adopts AC-DC-AC frequency-variable structure. The rectifier adopts 3-phase 6-pulse thyristor rectifying, IGBT DC chopping or 3-phase 12-pulse thyristor rectifying. Inverter adopts high voltage large power MOSFET to form full bridge resonant inverter. Inverter output adopts high efficiency ferrite matching transformer to accomplish power synthesis, impedance matching and electric isolation. Resonant tank circuit adopts secondary side series resonance.
The whole set equipment is composed of switch gear rectifying cabinet, inverter output cabinet, circulation soft water cooling system, console and positioning table.
