摘要：
A method for welding copper or a copper base alloy and iron or an iron base alloy characterized in that an element for enhancing the mutual miscibility of copper and iron and an element for refining the crystal grains of the weld metal is added to weld metal in a total amount of 1 to 25 percent by weight based on the weld metal, thereby preventing the welded portion from crack formation and segregation.
