发明名称 SPOT WELDING TOOL
摘要 PROBLEM TO BE SOLVED: To provide a spot welding tool capable of achieving a high-quality welding joint part while preventing electrode wear. SOLUTION: The spot welding tool is used for resistance welding of a workpiece and is provided with at least one electrode (4). Pressing elements (9) for pressing the workpiece are arranged on the electrodes (4) in the area of an electrode cap (5) and prevent the process-dependent warpage or bending of the workpiece. By such arrangement of the pressing elements additional pressure acts on the workpiece, specifically metal sheet and accordingly dispersed pressure application to the workpiece through the electrodes is generated and the bending of the workpiece is also prevented.
