Solid State High Frequency Welding Machine

Product Name: Solid State High Frequency Welding Machine

The Solid State High Frequency Welding Machine (all-in-one machine) is designed for straight seam induction (contact) welding of steel tubes. It mainly uses IRFP460 (MOSFET) and DSEI60-06A (fast recovery diode), rectifier diodes, and modular Power component consisting of high-power IGBT and other power devices. The high-power capacitor bank C and the inductance coil L form the current-mode parallel boost resonant circuit. This kind of circuit adapts to the high-frequency welded pipe with low load impedance and does not require the output transformer. This not only improves the efficiency but also increases the reliability of the whole machine.

Modular power module consisting of high-power IGBT and other power devices

The IGBT module used in the automatic pipe welding machine (all-in-one machine) combines the advantages of the high input impedance of the MOSFET and the low conducting voltage drop of the GTR, so that it can directly convert the rectified direct current of the ordinary three-phase 380V AC power into controllable alternating current. It overcomes the shortcomings of low voltage regulation efficiency and low power factor in traditional solid-state high-frequency welder isolation transformer and thyristor .

Compare to the traditional solid state high frequency welding machine, the Solid State High Frequency Welding Machine (all-in-one machine) has the advantages as following:

High Efficiency

Comparing to traditional solid state welder, save power for 15%-25%.

Less Area Covered

Easy installation

Less installation cost

Welding Quality

Benefitted from PWM precise control voltage and three level of filtering, the voltage output is stable, ripple coefficient is 50% lower than solid state welder. The welding quality is obviously better than traditional solid state welder.

The ERW pipe welding machine always packed by strong export standard wooden case, protected the machine perfectly.
