Abstract

Electrode tip for resistance spot welding appts of the type in which two steel plates are superposed, held between the electrode tip and the counter electrode, and submitted to a high intensity current, has a cavity e.g. >=1 annular (concentric) groove in the press. applying surface, which absorbs pressurised molten metal produced by thermal expansion.
