METHOD OF REINFORCEMENT WELDING TO SUPPRESS WELD CRACK

摘要

PROBLEM TO BE SOLVED: To provide a method of welding in which the fatigue strength is improved and the weld crack is prevented in a reinforcement welding in which a welding material having a low transformation temperature is used. SOLUTION: The welding is performed by suppressing a thermal history in a welding material having a low transformation temperature by moving a weld line in a straight line in the method of the reinforcement welding in which a welding material having a low transformation temperature is used.
