IPC: B23K20/12
Filed: 2003-10-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide a joining structure of dissimilar materials in which joining quality is secured, production cost is suppressed, and decomposition can be conducted when scrapping or recycling it, and to provide a method for joining dissimilar materials.  <P>SOLUTION: A aluminum material 1 and an aluminum material layer 3a of a clad material 3 are joined by friction stir welding, and a steel material 2 and a steel material layer 3b of the clad material 3 are bonded since an adhesive 4 applied on the clad material 3 is cured by friction heat, which is generated when the friction stir welding is conducted. In this way, the aluminum material 1 and the aluminum material layer 3a of the clad material 3 are joined by the friction stir welding, which is suitable for mutually joining aluminum materials, so that the joining quality is secured. Resistance welding of a combination of aluminum materials is abolished and thereby pretreatment for the aluminum material 1 is not required, so that the production cost is reduced. Furthermore, an alloy of the aluminum material 1 and the steel material 2 is not produced between the materials 1, 2, so that, when scrapping or recycling, the clad material 2 can be decomposed into an aluminum material part and a steel material part, by separating the clad material 2 into the aluminum material layer 3a and the steel material layer 3b by, for example, keeping the joined part at a high temperature.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
