Abstract
PURPOSE: To prevent the peculiar spiking defect of deep penetration electron beam welding at weld joint, by irradiating the second electron beam from different direction after irradiating the fitst electron beam to the extent not to penetrate through the material to be welded.
CONSTITUTION: The member to be welded, 1, 1 are butted and welding by the first weld bead 2 is carried out by the first electron beam to the extent not to penetrate the member 1. Next, the second electron beam by vignetted focus is irradiated from the opposite side so as to surround the tip end part 5 of the above bead 2 and the second weld bead 4 having a wide bead width, is formed by remelting. By the above method, spiking defect is prevented and also, perfect penetration electron beam welding of thick plate butt joint is able to carry out because backing strip is not used.
