| description | PURPOSE:To remelt a penetration bead part and correct it exactly by converging and deflecting an electron beam that penetrated a joining part and irradiating the penetration bead part. CONSTITUTION:When a material is welded by an electron beam 20 emitted from an electron gun, a penetration bead 18 of irregular shape is formed along the weld line by the electron beam that penetrates the joint plane. The penetrated electron beam 21 is converged to beam diameter about twice as large as that of electron beam 20. It is then deflected by the first deflecting coil 34 and the second deflecting coil 35 and irradiated to the penetration base 18 as a forming electron beam 22 at an angle of incidence of theta. The forming electron beam 22 moves along the weld line with movement of electron beam 20 in the direction of plate width and melts smooths the penetration bead formed at the joint part successively and continuously and corrects irregular shape. |
