Abstract
PURPOSE: To provide the subject process comprising welding a weld metal and a heat while subjecting the same to compulsory pressure forging in the cooling step directly after the welding, thereby making tenacious the joint portion of a large size weld structure and a restraint member.
CONSTITUTION: In the cooling step where a weld metal directly after welding is cooled, the variation in the temperatures of weld metal and the heat influenced part are detected by a temperature senser 5 fitted to the side surface of a pressure forging blow part 1, and pressure forging is carried out by a blow hammer 2. By the application of the forging and plastic processing, reduction of residual stress of the weld metal and conversion of compression stress are attempted, and the joint part comes to have high strength and high tenacity. Also, high temperature cracks are difficult to be generated. Further, when the head part of the blow hammer 2 is rendered into a flat head conical type, crotching in a workpiece 9 and spraying are effectively prevented
