Abstract
There are provided an electrode tip dressing apparatus and an electrode tip dressing tool for resistance welding, which are miniaturized by reducing a rotational driving-force of a dressing tool. By adjusting a curvature radius of a dressing portionof a dressing tool, a contact width, wherein a top electrode tipabuts to the dressing portionof the dressing tool, is adjusted from a rotational center of the dressing toolto the outer side of the dressing tool. Dressing work done with the dressing toolis thus made to be constant at the whole area of the dressing portion, from the rotational center of the dressing toolto the outer side of the dressing tool. Accordingly, excess dressing work, which brings decline of productivity, can be avoided, thus enabling to dress the top electrode tipwith the minimal dressing work. A rotational driving-power of the dressing toolis thereby reduced, enabling to labor-save and miniaturize the electrode tip dressing apparatus.
