In many industrial sectors, it is necessary to combine different materials due to the different requirements, e.g. for deformability or also due to the level of material costs.
Welding, as one of the oldest and established joining processes, proves to be very well suited for this purpose. Depending on the material to be joined, however, it poses challenges in terms of the parameters to be selected, process control, and the effects of the aforementioned on strength and corrosion resistance, but also with regard to cleanliness (in the sense of freedom from particles). In particular, new challenges often arise in practice when joining dissimilar materials.
