The Development of a Technology for the Welding of Dissimilar Joints of Copper and Austenitic Steel

Welded joints made of copper alloys and austenitic steels are commonly used in heat exchangers, pipelines and other equipment typical of the power industry. The above-named materials are difficult to weld because of their varying thermal properties. The obtainment of proper welded joints necessitates the performance of tests aimed to develop a technology enabling the welding of copper and austenitic steels. This article provides insight into research dedicated to the development of a TIG welding-based technology enabling the joining of copper and austenitic steel.
