ERW Welding Machine

Product Name:  ERW Welding Machine

The ERW 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.

It has following advantages:

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

For example 100kw solid state welder, the traditional welder installation cost is around USD800(purchasing cable, nozzles, cable bridge and brackets), moreover, welder room or elevated platform is necessary, all the cost will be about USD800-1600.

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.
