Netherlands Variable frequency flash butt welding machine

The inverter welding machine controller is divided into two kinds of intermediate frequency and frequency conversion. The output frequency of the intermediate frequency controller is 1KHz, and the welding current is DC. It has the advantages of high control accuracy, stable output current, small inductive reactance, light welding transformer and less welding spatter. The output frequency of the variable frequency controller can be adjusted, which can adapt to transformers of different frequencies. The secondary of the transformer does not need rectification, and the structure is simple and reliable.

Product Description

Variable frequency flash butt welding machine

Key features:

1 inverter welding controller is divided into two kinds of intermediate frequency and frequency conversion, intermediate frequency controller output frequency is 1KHz, welding current is DC, with high control accuracy, stable output current, inductive reactance effect is small, welding transformer light weight, welding less spatter and other advantages. The output frequency of the variable frequency controller can be adjusted, which can adapt to transformers of different frequencies. The secondary of the transformer does not need rectification, and the structure is simple and reliable.
2.
will butt the workpiece, automatic clamping,Then through the gas-liquid control, the first power-on slowly push the workpiece welding surface oxidation and convex uneven flash to remove the welding workpiece end face thermal plasticization,The welding area becomes hotter and hotter, and the speed of butt welding also accelerates.,Flash and spatter make the two contact surfaces completely welded together,.Finally againRapid pressurizationTop forgingWelding both end faces of welding, cut off the current and the welding is completed.This kind of welding has high strength, good compactness, no false welding, no slag inclusion and no pores.

Main applications:
1. All kinds of tableware, knives;
2. Bicycle rims, motorcycle rims, car rims or similar belt rings;
3. All kinds of steel belt, steel bar, construction steel bar, round pipe, square pipe;
