Hybrid car bodies, doors and seat frames are increasingly used to exploit the comparative advantages of steels and aluminum alloys for car lightweighting. Adhesives and mechanical methods are commonly used to join aluminum and steel in hybrid car parts, while welding have been used in a few cases so far. However, aluminum-to-steel welding is well established in other industries; for example, in shipbuilding it is often performed by using transition joints, which are fabricated by solid state welding (such as explosion welding). Solid state methods are preferred because the low temperature hinders the formation of brittle intermetallic compounds. Several hybrid welding methods, which could be used for car building, including resistance spot welding and continuous arc welding with or without transition joints, were examined and are reported. Both explosion-welded and roll-bonded transition joints are considered. Welded specimens were subjected to metallurgical and mechanical characterization, and to corrosion tests.
