Flash Butt Welding Machines

RANGE: [ 1 – 250 kVA ]

Flash Butt Welding is a resistance welding process used for joining two metal workpieces by generating heat through electrical resistance at the joint interface. The components to be welded are clamped between electrically conductive electrodes and brought together under controlled pressure. In Keje Electric Flash Butt Welding Machines, one platen remains stationary while the other moves hydraulically. As the parts approach each other, flashing occurs due to electrical resistance, raising the temperature of the mating surfaces. Once the required temperature is reached, an upsetting force is applied to forge the joint, producing a strong and uniform weld.

These machines are designed for high productivity, consistent weld quality, and minimal material loss, making them ideal for industrial manufacturing applications.
