Dissimilar Joint Welding: A Comprehensive Guide
Mixed joints are all weldable material combinations in which the components to be joined have different properties. In many constructions, a wide variety of materials are used for cost reasons or due to physical or chemical stresses. It is therefore often necessary to carry out welded joints with these different materials. When welding different steels or non-ferrous metals, a number of points must be observed to ensure that the weld seam meets the requirements placed on it under operating conditions.
Welding different metals poses a number of challenges. These are the differences in physical properties, such as thermal conductivity and expansion, magnetic properties, metallurgical structure and corrosion resistance. Nevertheless, welding has evolved considerably and there are specific processes that allow even the most diverse metals to be welded.
