Title:
METHOD FOR REMOVING WELDING DISTORTION
Document Type and Number:
Japanese Patent JP3944006
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a removing method of welding distortion by which welding distortion generated in the vicinity of a weld bead formed in the weld zone between steels is surely removed so that the steels after welding are in the target welding position and also welding is performed with high safety.
SOLUTION: In the removing method of the welding distortion which is generated in the vicinity of the weld bead formed in the weld zone of the steel, by using a TIG ( tungsten inert gas ) welding machine, setting the amount of heat input to the weld bead by an arc from the TIG welding machine by using the measured value of the deformation caused by welding the steel and heating conditions including an electric current and voltage to be imparted to the electrode of the TIG welding machine, the welding distortion in the vicinity of the weld zone of the steel is removed by heating the weld bead with the arc from the TIG welding machine.
