  • Method of forming fillet arc welded joint and fillet arc welded joint
    Patent number: 10035208
    Abstract: Stiffening beads (55A, 55B) are formed in turned portions in a region of a fillet bead (53) formed in a single stroke manner. At this time, it is set in such a manner that welding start positions of the stiffening beads (55A, 55B) are in a region near the fillet bead and do not exist independently without mixing with other weld beads.
    Type: Grant
    Filed: November 28, 2013
    Date of Patent: July 31, 2018
    Assignee: NIPPON STEEL & SUMITOMO METAL CORPORATION
    Inventors: Shoko Tsuchiya, Shinji Kodama, Yuuichi Yosida, Yoshinari Ishida, Masahiro Ogawa
  • Fillet arc welded joint and method of forming the same
    Patent number: 9943922
    Abstract: At least one stiffening bead (32) is formed by arc welding on a surface of at least one of metal members in addition to a fillet bead (3) formed by fillet arc welding. The stiffening bead (32) is formed to have an angle of 45° to 135° with respect to the fillet bead (3) and to overlap with the fillet bead (3). The sum total l1 of lengths of stiffening beads (32) can be, for example, 0.5 times or more of a length L of the fillet bead (3).
