Steel Pipe HF Welder

Product Name: Steel Pipe HF Welder

The steel pipe HF welder (all-in-one machine) is mainly composed of full-bridge rectifier, filter, modular power module (consisting of high-power IGBT and other power devices), secondary rectifier circuit, inverter circuit (consisting of MOS pipe), load and other components.

The steel pipe HF welder (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.

The advantages of the Steel Pipe HF Welder:

High Efficiency

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

Less Area Covered

Saving 60% area than traditional solid state welder.

Easy installation

Comparing to the 5-7 days for traditional solid state welder installation, high efficiency switch welder installation is 1 day.

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.
