Abstract
PURPOSE:To obtain sufficient weld-joint characteristics, when T-type or L-type joint is welded using a high output high density beam, by repairing weld defects generated after the welding work at the weld zone on the side of incidence of the beam and on the opposite side. CONSTITUTION:A T-type joint is made of parts 4 and 5 by the electron beam 6 welding, and the weld zone 7 is formed. Hereupon, a part of molten metal spouts out opposite against the direction of incidence of the beam, and forms the molten metal drop 9; as a result, an undercut zone is formed at the corner on the incidence side depending on the lack of molten metal. In case of circumstances, a lack of penetration is caused. For the purpose of efficiently repairing above stated defects at the weld zone and of forming good reinforcement weld, an additional welding is carried out on the corner of above stated weld zone 7 depending on the unfocused electron beam; hereby, the reinforcement weld 11 is formed. Moreover, the filler metal 10 is preferable to be used for the corner where the undercut is caused. For the L-type joint, the welding is performed similarly to above case.
