Welding method of steel band

Abstract

Abstract PURPOSE:To weld plural pieces of steel bands having high strength at one time by cutting the weld zone of steel bands at about 45 deg. angle, arraying plural sheets of the bands closely in parallel on the support plate of a laser working machine, and welding continuously the inclined surfaces under blowing of Ar. CONSTITUTION:Steel bands 2a-2f of, for example, 0.25mm. thickness and 9mm. width, which are cut of weld zones at about 45 deg. relative with the longitudinal direction are arrayed closely in parallel on the pedestal 2 of a welding machine, and are correctly fixed by means of retaining metals 4a, 4b. Gaseous Ar 9a, 9b are ejected to weld zones 2', 2'' for the purpose of preventing oxidation and the weld zones are continuously welded by a laser light 8. The steel bands 2a, 2f having the burn-through of weld at both ends are removed after the welding and the other steel bands are used as a belt for welding.
