METHOD resistance welding of wire products, valves, pipes, steel and a lengthy Contact spot welding machines with shaped top electrode PROCESS

摘要

1. A method of resistance spot or projection welding wire products, valves, pipes, metal bands and different elongated metal wherein the welded parts arranged on the welding table, these parts are compressed between the welding electrodes and welding current is supplied, characterized in that the upper electrode nominate of the welding table is moved to the intersection of the welded parts, and then compressed welded parts between electrodes, weld, after which the upper electrode is removed in a welding stol.2. A method of resistance welding according to claim 1, characterized in that, after addition, when the upper electrode is pushed from the welding table, produce two or more splices, wherein after each welding upper electrode is not removed in a welding table, and after a series of welds upper electrode clean the welding stol.3. A method of resistance welding according to any one of claims 1 and 2, characterized in that the welding table of the pushing two or more upper elektrodov.4. Method sided contact spot or projection welding wire products, valves, pipes, metal bands and different elongated metal wherein the welded parts arranged on the welding table is compressed parts between the electrodes and the conductive lining and fed to the welding current electrodes, wherein the electrodes extended from the welding table and fed to the top of the welded parts, and the bottom is pressed against the conductive pad welded parts, weld, and then clean the electrodes in quarrels intramural stol.5. A method of resistance welding according to claim 4, characterized in that, after addition, when the electrodes are pushed out of the welding Art
