Flash Butt Welding

Flash Butt Welding Process:
Flash Butt Welding machines start the welding operation by slowly approaching, without pressure, the two parts to be joined: when these two ends come into contact, an electric arc strikes between them and in a very short time they are brought into a pre-melting condition; at this point the two end, in a semi-solid status, are heavily pressed one against the other by the upsetting force, which results in a high quality joint with the welded area totally impurity free.
