摘要
PROBLEM TO BE SOLVED: To provide a flux cored wire and a method for joining different materials, by which flux cored wire and method, the joined strength and welding efficiency can be improved in the case of strongly joining different materials, such as high tensile strength steel and 6000 series aluminum alloy, by a fused welding operation.;SOLUTION: The flux in the flux-cored wire has a fluoride composition which contains a specified amount of AlF3 and does not contain chloride. Further, an outer shell of aluminum alloy contains 1 to 13 mass% of Si. As a result, the high joined strength is achieved in the case of strongly joining different materials, such as high tensile strength steel and 6000 series aluminum alloy, by the fused welding operation.;COPYRIGHT: (C)2008,JPO&INPIT
