Brief introduction of flash butt welding machine

Flash butt welding is widely used for the longitudinal connection of steel bars and the welding of prestressed steel bars and screw end rods. The principle of flash butt welding of steel bars is to use a butt welder to bring the two steel bars into contact with each other. After the steel bars are heated to a certain temperature and softened by a strong current of low voltage, they are subjected to axial pressure upsetting to form a butt welded joint. Continuous flash welding, preheating flash welding and flash-preheating-flash welding are commonly used in flash butt welding of steel bars. For grade IV steel bars, energization heat treatment is sometimes carried out after welding.

Flash butt welding machine application

The performance characteristics of the UNS flash butt welding machine of Zhongbang welding machine:

Adopt a new generation of TCW-33EII series controller

It can realize the optimal control of the entire welding process of flashing and upsetting, and is reliable and high in accuracy. Compared with ordinary resistance welding machines, the power supply capacity required for welding workpieces of the same cross section is small and the energy consumption is low.

A precise regulating valve is installed in the hydraulic system of the welding machine

The flashing speed can be adjusted steplessly to ensure the stability of the flashing process, so that the welding workpiece joints have less slag, good metallography, firm and beautiful appearance.
