The thermal joining of different materials such as steel and aluminium is of crucial importance in automotive lightweight construction. However, this process is particularly challenging due to the different physical and chemical properties of the materials.

It is difficult to achieve high-quality, stable results and the options for further working of the semi-finished parts are significantly restricted. The solution to these challenges is a welding process with reduced heat input – the Cold Metal Transfer (CMT) process developed by Fronius.

The low level of spattering coupled with the constant and extremely stable arc deliver optimum welding results. International automotive industry supplier Magna Steyr has taken CMT and developed a technology that not only makes it possible to manufacture bodywork parts much more cost-effectively, but also allows weight savings to be achieved too.
