A method for producing a spark plug for internal combustion engines, having a metallic shell, a ceramic insulator held in the shell, a center electrode embedded in the insulator, and a ground electrode implemented as a bridge attached to the front end of the shell, wherein an end piece made of a precious metal is attached to the front end of the center electrode and a counterpart is attached to the bridge opposite the end piece, between which is formed a spark gap. A cylindrical body made fully or partially of the precious metal or precious metal alloy intended for the end piece and that is longer than the end piece is welded onto the front end of the center electrode. A bridge is used that has, in the center, a hole, the cross-section of which is matched to the cross-section of the cylindrical body. The bridge is placed on the front end of the shell in such a manner that the forward-facing end of the cylindrical body enters the hole in the bridge. The cylindrical body is welded to the bridge, and lastly the spark gap is created by cross-cutting the cylindrical body.
