Abstract

PURPOSE:To shorten the repairing time by welding a padding for repair after removing cracks generated in a tie-wire hole of a moving blade, and inserting a plug slightly smaller than the hole diameter into the hole. CONSTITUTION:When any crack is generated in a tie-wire hole 2 of a moving blade 1, the crack is removed, and a round bar-shaped assistant plug 5 for welding slightly smaller than the hole diameter of the tie-wire hole is inserted into the hole. Then, a multilayer padding 7 is formed on the area where the crack is removed, using a welding rod 6. The shaping operation is performed by once reaming the tie-wire hole 2. The amount of the padding is thus reduced, and the repairing time can be shortened.
