PROBLEM TO BE SOLVED: To obtain good joining by preventing defective joining, deformation or the like in the vicinity of the bottom of a hole part and also preventing the retention of a oxidized film. ;SOLUTION: This method for building up the hole part 3a passing through a base metal 3 has a process where a bottom is formed by stopping up one side of the hole part with a liner member 5, a process where weld metal 4 is put on the bottom of the hole part and a process where a friction bar 1 is forcefitted into the hole part while rotating the bar whose outside diameter is smaller than the bore diameter of the hole part. A plate-like spacer 6 having a through hole 6a of an approximately same diameter as the hole part is inserted between the base metal and the liner member making the through hole coincide with the hole part.;COPYRIGHT: (C)2001,JPO
