Abstract

PURPOSE: To perform the captioned prevention and obrain the sound weld zone by performing continuous welding while adding one or more kinds of Te, Se, S, Sb or compounds of their elements to the portions to be heated of both edges of a strip.
CONSTITUTION: In high-frequency electric welding, the welding is done continuously while one or more kinds of Te, Se, S, Sb or compounds of their elements are being added to the portions to be heated of both edges 1 of a strip, that is, to the portions near strip both edges 1 which are heated by the electric power supplied through power feed contactors 2 and partly melt as well as onto the molten metal A. These make the production of weld defects obsolete and improve the butt part impact characteristic, production yield, etc. of the products.
