<p>PROBLEM TO BE SOLVED: To provide a joining method of aluminum and copper having the joining strength higher than that of the conventional method. SOLUTION: This joining method of the aluminum and the copper is composed of a tin coated layer forming process, which the joining surface is covered with tin by allowing molten metal containing tin to contact at least joining surface of copper member with aluminum member, and tin coated layer is formed producing solid solution at the interface between copper member and tin, and a weld joining process which electric current is supplied between electrodes and welding is executed, while allowing tin coated layer of copper member to contact aluminum member and pressurizing copper member and aluminum member with each separate electrode.</p> |
