STOPGAP WELDING METHOD IN RE-WORKPIECE

摘要

PROBLEM TO BE SOLVED: To reduce a deformation of a mother metal due to a welding distortion, in the case where an existing hole is buried by a welding thereby to perform a re-work for forming a novel hole in said buried part.;SOLUTION: An inner ring 4 of ceramics having a smaller column shape than that of a novel bolt hole 6 is so disposed in an existing bolt hole 1 as is positioned in the axial core of the novel hole 6, and the existing bolt hole 1 is so buried by welding with a molten metal 5 that said inner ring 4 is disposed, and a novel bolt hole 6 is worked and formed by removing the inner ring 4 after said burying operation.;COPYRIGHT: (C)2015,JPO&INPIT
