Abstract
PURPOSE: To deprive a tension remaining stress by applying heat or bead pad on an outer surface of a backplate after repairing by a fillet weld. CONSTITUTION: A backplate 3 is attached to an outer surface 8 having a crack 2 on a pipe 1. After repairing by a fillet weld on an edge of the backplate 3 and the outer surface 8 on the pipe 1, the heat 5 is applied to an outer surface 10 of the backplate and a surface of a fillet weld 4. When the heat 5 is applied to the outer surface 10 of the backplate or when a bead pad is applied to the outer surface 10 of the backplate, a temperature distribution 11 from a high temperature at the outer surface 10 of the backplate to a lower temperature at a surface 7 within a mother pipe can be obtained.
