摘要: An apparatus and method for fastening dissimilar metals like steel aluminum utilizes a rivet spot welding machine. The are stacked the heat from welder's electric current softens lower melting point allowing to penetrate weld layer. fastener may be used join stacks with several layers of different materials apply threaded socket or stud made titanium an magnesium alloy structure. Layers non-conductive plastic ceramics also affixed conductive layer using compatible material that extends through pilot hole.
