Production Mixed-metal Joints

Aluminium parts are welded to steel in the flange zones, which in turn allows the application of conventional spot-welding in the assembly line. This means that no additional joining techniques like punch riveting in the line are necessary. An important step towards affordable lightweight design. In addition Magna Steyr has optimised the CMT welding for single-sided welding of zinc coated steel sheets with aluminium sheets. Suitable welding wires were developed jointly with Light Metals Technologies Ranshofen (LKR).

Today’s car body manufacturing is increasingly fostering the combination of different materials. The lightweight potential of a car body is optimised according to the material properties. Therefore, it is necessary to apply cold joining techniques (i.e. punch-riveting), as aluminium and steel cannot be welded easily. Conventional car body manufacturing is, however, becoming more complex and expensive through the use of such additional joining techniques. The choice of parts...
