Abstract

PURPOSE:To weld a steel material to be welded by a welding material having a strength lower than the strength of said steel undergoing restraint by welding, to cool the same, and thereafter to heat the welded part and to subject the welded parts to aging thereby to increase the strength of the soft welding joint more than the strength of the material to be welded. CONSTITUTION:A steel material to be welded such as a structure steel or the like is welded by a welding material having a strength lower than that of the steel material. In this case, welding is carried out preferably by use of a shield gas prepared by mixing 0.2 to 5% by volume of a nitrogen gas into a gas consisting more than a member selected from the group consisting of argon, helium and a carbonic acid gas. Then, the welded steel is cooled, and thereafter the welded part is heated and held at a temperature in the range of from 200 to 300 deg.C and then subjected to aging.
