Document Type and Number:
WIPO Patent Application WO/2021/039866
Kind Code:
A1
Abstract:
Provided is a resistance spot welding method which enables stable achievement of a desired nugget diameter without occurrence of scattering even when an influence of disturbance is great. In accordance with the mean value or the time integration value RA of inter-electrode resistance from an energization start time to an intermediate energization time Ta of a main energization, compressing force FA is set in the main energization after the intermediate energization time Ta.
