The present study discusses direct resistance projection welding of a multi-core copper cable to a discharge brass terminal. Resistance welding was carried out with a conventional machine. The upper tungsten electrode, which comes into contact with the multi-core copper cable, and the lower copper electrode, on which the brass terminal is lying during welding, are described.In the experimental research, the optimum welding parameters for direct welding (i.e.welding without an intermediate layer or a brazing filler material) of the two workpieces concerned were found. The welded joints obtained were subjected to a strength test, and metallurgical and resistance investigations. The strength test showed that the welded joint was quality welded and had higher strength than the brazed joint. With a heat resistance test during current conduction, it was found that the joint heated much less than the brazed joint. Metallographic investigations of macro-specimens and a chemical analysis at the copperžbrass joining line are described.
