SQ/AS
SQ/AS models are suitable for butt welding solid materials, tubes, profiles and closed sections, producing high-quality joints. They are particularly suitable for high-volume production, with fully automatic controls supporting speed and efficiency.
SQ/AS machines begin the welding operation by slowly bringing the two parts to be joined close together without touching; an electric arc is then generated between them, bringing them to a pre-molten state in a very short time. At this point, the two ends, in a semi-solid state, are pressed firmly together by the upsetting force, producing a high-quality joint completely free of contamination. read more…
