Title:
WELDING METHOD AND JOINING MEMBER
Document Type and Number:
WIPO Patent Application WO/2019/049792
Kind Code:
A1
Abstract:
The present invention realizes a welding method with which it is possible to manufacture a joining member having superior toughness. The welding method includes: a first heat-inputting step for forming a joined section in which ferrite-based single-phase stainless steels are joined with each other by inputting heat from a first heat source; and a second heat-inputting step for inputting heat to the joined section from a second heat source so that the cooling speed of the joined section reaches 500ºC/s. or less while the temperature of the joined section is in a range of 1300ºC to 700ºC after the first heat-inputting step and before the temperature of the joined section decreases to 700ºC.
