METHODS OF WELDING DIFFERENT MATERIALS

Abstract

The invention relates to a method for welding different materials, used to solve the problem of poor weld strength of existing welds of different materials. The method includes: placing the first and second workpieces in a vacuum environment, with an intermediate material containing copper at the interface between the first and second workpieces; and heating the vacuum environment to 960-1060℃ and then maintaining it for 5-15 minutes to bond the first and second workpieces together. This makes it possible to achieve a bond with higher strength.
