New Techniques for Joining Steel and Aluminum | 2017

The type of welding process used to join steel and aluminum parts is typically dictated by the design requirements of the joint “Solidstate welding offers the best joint strength when welding aluminum to steel,” says Eff “The friction welding family (inertia, direct drive and linear friction welding ) have produced aluminum to steel joints that exceed the strength of the aluminum alloy Resistance spot welds are also capable of joining aluminum

Joining of automotive sheet materials by frictionbased

01022018· Although the dominant welding method for joining steel car bodies is resistance spot welding (RSW), it does not necessarily produce a robust joint to weld aluminum to steel This is mainly attributed to the poor performance of the weld because of the formation of a thick intermetallic compound (IMC) reaction layer between the aluminum and steel during RSW
