Abstract
The invention relates to a device for protecting an electrode during the resistance welding of workpieces, in particular sheet metal. Said device comprises a strip that is placed over the electrode and can be displaced in relation to the latter, a backing material of said strip having an electrically conductive coating. To improve the welding quality, the coating is applied to the opposite side of the strip from the electrode and consists of a material, whose hardness is less than that of the backing material of the strip. The soft, electrically conductive coating improves the transfer of current from the electrode to the workpiece, thus preventing weld spatter and improving the welding quality.
