Abstract
PURPOSE: To make preventable the cracking to be generated at the toe of weld, when the carbon steels of dissimilar carbon content are to be welded along the closed curve, by gradually displacing the position of irradiation of the electron beam to the side of low carbon steel, after finishing one turn of the welding.
CONSTITUTION: First, the electron beam 5 is directed to the seam 3 of the butt face of materials 1 and 2 to be welded, which are then rotated for finishing one turn of the welding along the entire circumference. And then, after the time t0 passes, the current of electron beam is held at Ib0 while the time ti; under this condition, the gradually increasing deflecting current IR is supplied to the deflecting coil 8, until the current is increased up to IRO. Hereby, the tip of the electron beam 5 displaced from 5a to 5b, and heats and melts the position along the outer circumference of the formerly formed welding bead 6; hereupon, the electron beam 5 gradually attenuates, so that the shape of bead at the toe of weld becomes smooth. This displacement is carried out gradually transferring to the low carbon steel material 1 to be welded. Hereby, the concentration of impurities gradually decreases, so that the cracking generated at the toe of weld of the second layer can be reduced.
