Abstract
In the indirect spot welding apparatus, a lower limit in a stable pressing force region where the pressing force of the spot welding electrode against the metal sheets can be controlled within a tolerance of ±10% ranges from 70 N to 200 N and an upper limit in the stable pressing force region ranges from 800 N to 2000 N, and an overshoot OS(%)=(PL−AL)/AL×100 of the pressing force occurring when the spot welding electrode is pressed against the metal sheets is controlled to be 10% or less.
