Document Type and Number:
Japanese Patent JP2012179655
Kind Code:
A
Abstract:
To provide a method of introducing compressive stress in a welded joint having at least one weld toe.
The method includes the steps of: covering the weld toe of the welded joint with a resistance wire (206); heating the weld toe by the resistance wire, where the weld toe is heated to a predetermined temperature (208); maintaining the weld toe at the predetermined temperature for a predetermined amount of time (210); removing the resistance wire from the weld toe (212); and quenching the weld toe with a cooling medium (214), wherein compressive stress is introduced to the weld toe during the quenching.
