Abstract
PURPOSE: To prevent the occurrence of phenomena such as weld crack owing to the quenching of weld portions, and machining difficulty as with conventional welding, by radiating an electron beam again to the portion welded by an electron beam thereby delaying the rate of cooling of said welded portion.
CONSTITUTION: In welding the points AWE on the weld one of the welding works 4 on a truck 4 by the electron beam 2 of an electron gun 1, first the A-B points are welded at the power density of welding, after which the electron beam 2 is returned to the A point, is set at the power density of postheating and is moved up to the B point. Thence, again the B-C points are welded at the power density of the welding, after which it is returned to the B point. From this point on, the foregoing similar operations are repeated and the entire length AE is welded. By delaying the rate of cooling of the welded portion in this way, the weld crack owing to quenching is eliminated and the defect of conventional method that working becomes difficult on account of increased hardness of the weld zone is improved.
