PROBLEM TO BE SOLVED: To solve such a problem that copper material is not satisfactorily dissolved when two kinds of different metals of copper material and steel material are welded to each other.SOLUTION: A welding method of copper and steel and an application of the welding method are provided. The welding method includes a butting method or a fitting method of weld end parts on two kinds of materials of copper and steel. A heating part of a heat source supply facility welds a weld end part of copper material and a weld end part of steel material under the protection of shield gas, a tip of the heating part is biased to a direction on which the copper material is located, the weld end part of the copper material and the weld end part of the steel material are dissolved at the same time and, further, are alternately molten.SELECTED DRAWING: Figure 1a |
