Resistance seam welding
Work was conducted to develop the capability to produce miniature resistance seam welds at the Bendix Kansas City Division (BKC) of Allied Corporation. This effort was initiated to weld aluminum foil to polyimide-backed copper foil on a flat cable. A parallel gap resistance welding head capable of accessing material from one side only was designed and fabricated for this purpose. Welds were made between aluminum and copper foils using the parallel gap resistance seam welding head. Bonds were made proving the welding head design was feasible. Aluminum to copper weld joints were analyzed by cross sectioning, electron beam microprobe analysis, and environmental testing. As expected with this material combination, testing indicated the presence of brittle, crack sensitive intermetallics in the weld zone. Work was expanded to develop a general resistance seam welding process capable of welding metal foils where there was access to both sides of the material. An opposed electrode welding head was designed and fabricated for this purpose. 11 figs.
