Flash butt welding process

SQ/AS models are suitable for flash butt welding solid material, pipes, profiles and hollow sections by obtaining high quality joints. They are particularly suitable for mass production with fully automatic controls aiding speed and efficiency.

SQ/AS machines start the welding operation by slowly approaching, without contact, the two parts to be joined; then an electric arc strikes between them and in a very short time they are brought to a pre-melting condition. At this point the two ends, in a semi-solid status, are heavily pressed one against the other by the upsetting force, which results in a totally impurity free high quality joint.
