| Abstract: | A method for spot-welding of aluminum and copper with a transition joint (a joint ithout potential difference) was put forward. Spot-welding aluminum and copper with an AC welder can revent the oxide film of Al2O3 from breaking and heat activation, pressure and electro-magnetic tirring force can be made use of to cause solid solution of aluminum and copper and their diffusion and the ovement of the surface of liquid aluminum so as to spot-weld aluminum and copper and achieve a weld oint that has a higher strength than aluminum. A special way for the application of substitution of luminum for copper is given. |
