Claim:
1. A resistance welding electrode comprising: a shaft-shaped holder having an annular wall with a conical blind receiving recess formed inside the wall and increasingly reducing up to a bottom of the recess; and an electrode part including an electrode cap and a rod electrode, said electrode part having an annular circumferential lip facing the holder, wherein the electrode part and the holder are configured so that they are removably connected with one another by inserting the annular circumferential lip into the conical blind receiving recess formed inside the wall of the holder so that the annular circumferential lip reduces, and press-joining establishing an interference fit between an outer conical surface of the annular circumferential lip of the electrode part and an inner conical surface adjoining the conical blind receiving recess in the wall of the holder having a cone angle in a range of about 1 to about 3 degrees, with the annular circumferential lip of the electrode part contacting the holder being restrained in the conical blind receiving recess disposed in the holder through conical deformation of the annular circumferential lip inside the conical blind receiving recess as a result of the press-joining so as to retain the electrode part on the holder, and wherein the electrode part and the holder have at least one cooling bore, wherein the holder and the electrode part are additionally in axial contact with each other via a radial support surface which forms a stop when the holder and the electrode part are press-joined.
