Electrode life tests were conducted in resistance spot welding of organic composite coated steel sheets. The electrode lives obtained were almost equivalent to those of ordinal coated steels despite the fact that electrodes during the tests rapidly wore out. The long electrode lives can be attributed to a high contact resistance between the material coated with an organic film and an electrode. That is to say, although the high contact resistance leads to the rapid wear of electrodes caused by a frequent surface flash, this in turn effectively restricts a current path into a specific contact area between the material surface and the electrode and maintains a high current density sufficient to form a nugget even when the electrode wears out.
