The all-transistor (solid-state) high-frequency welding machine is designed for the straight seam induction welding of steel pipes. The module composed of MOS high-power devices constitutes the oscillation part, and the power capacitor bank C, the inductor coil L and the reliable protection control circuit constitute a constant current type inverse Changer. The solid-state high frequency is realized by the sequential control system to realize the equipment chain control and fault display function.

The three-phase input voltage is stepped down and isolated by a step-down transformer, and then rectified into a DC voltage of 250 volts through a three-phase fully controlled rectifier bridge. After two-stage LC filtering, it is sent to the inverter bridge, inverted into alternating current of the required frequency, and finally output to the load through the tank circuit.
High-frequency welding machines can be used for welding metal pipe fittings, such as: copper pipes and copper pipes, copper pipes and steel pipes, steel pipes and steel pipes, steel pipes and iron pipes, copper pipes and iron pipes, iron pipes and iron pipes, copper pipes and aluminum pipes , Butt welding, plug welding, sleeve welding of steel pipe and aluminum pipe, aluminum pipe and aluminum pipe, etc., used for welding metal pipe fittings
