FIELD: metal welding processes and equipment, namely butt fusion welding of hot rolled steel designed for cold rolling.
SUBSTANCE: method of flash welding of strips with thickness 1.5 - 6.00 mm comprises steps of placing ends of strips to be butt welded under electrodes and joining them by welding at predetermined parameters; selecting main parameters of welding process according to nominal thickness H of metal; setting flash value , mm; setting upset value δ = 2.0*H0.7 mm and time period of flash upset τ = 0.33*H0.45 s.
EFFECT: enhanced efficiency and quality of welded seams, lowered metal consumption.
