Abstract
An electrode whose electrode surface is a substantially convex curved surface and which has at a center portion a recess set at a predetermined depth allowing a welding trace formed on a metal body surface to reach a deepest portion when a nugget is formed in a satisfactory manner by the spot welding is used as at least an electrode for performing the spot welding. The spot welding quality is judged based on a shape of the welding trace formed on the metal body surface by the spot welding in correspondence with the recess.
