PROCESSING TOOL FOR ELECTRODE FOR RESISTANCE SPOT WELDING, PROCESSING DEVICE FOR ELECTRODE FOR RESISTANCE SPOT WELDING, AND PROCESSING METHOD FOR ELECTRODE FOR RESISTANCE SPOT WELDING

摘要

A transfer processing unit of a processing tool for an electrode for resistance spot welding that is configured to mold, through transfer processing, a projection portion and a plurality of recess portions at an electrode tip portion bulging into a projecting shape is provided with a plurality of protrusions that are configured to mold the plurality of the recess portions respectively. A virtual plane that links tips of the plurality of these protrusions with one another assumes a shape coinciding with a surface shape of the electrode tip portion bulging into the projecting shape before transfer processing.
