Abstract

PURPOSE:To make the method for repair in the title easy by forming a groove for welding on a cut off wire element and welding the groove for welding after providing a backing sleeve for welding. CONSTITUTION:A turbine bucket is formed by making a moving blade group 5 by connecting adjacent plural moving blades 1 by a lacing wire 3 and arranging scores of this moving blade group 5 along the circumferential direction of a turbine rotor. In this case, when the wire 3 is cut off and repaired, a welding connection part 9 between a cut wire element 3a and its appropriate moving blade 1 is melted by heating and the concerned element 3a is moved to the left. And then cut parts 15a, 15b are processed flatly and grooves for welding 17a, 17b are formed with a preset angle. Then, after inserting a reinforcing sleeve 19 for backing, both elements 3a, 3b are brought in contact with each other and entire outer circumference of both grooves 17a, 17b are welded and then, its repair is over.
