Title:
GAS SHIELDED ARC WELDING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/189632
Kind Code:
A1
Abstract:
Provided is a gas shielded arc welding method that allows for an increase in fatigue strength of a welded spot, and thus allows for a reduction in thickness and a reduction in weight of a component. This gas shielded arc welding method comprises welding a steel material by melting a welding material and a portion of the steel material under a flow of shielding gas. The steel material has a tensile strength of greater than or equal to 1180 MPa. The welding material contains Cr in an amount of 6.00%-15.50% by mass and Ni in an amount of less than 9.00% by mass relative to the total mass of the welding material.
