Title: Resistance spot welding - where electrodes are lifted off workpieces when the welding current it switched off, reducing electrode wear
Inventor: SCHERUEBL DIETER
IPC: B23K11/11
Filed: 1979-02-13
Abstract: The workpieces which are to be welded are pressed together by at least one welding tool to form a joint surface, through which an electric current is fed for a brief period of time, followed by switching off the current. When the current is switched off, the welding tool is simultaneously lifted off the welded zone. Spot welding uses currents of ca. 10,000 amps. at below 10 volts, and causes wear of the electrodes. This wear results in a change in the spot dia. and thus a change in the electrode current and pressure so uniform welds are not obtd. The invention appreciably increases the working life of the electrodes by about four times in comparison with the life obtd. in similar conventional processes.
