Composite material with explosion welded intermediate part

摘要

The method involves producing an intermediate piece (4), which consists of an area made of steel or a titanium-based-material and another area made of a copper or aluminum based material. The areas are connected under formation of a connecting zone (7) by explosion welding. A section is connected with the former area under formation of a welding seam and another section is connected with the latter area under formation of another welding seam by a fusion-or diffusion welding process. The sections and the areas consist of a material with same base metal.
