WELDING OF CONSTRUCTIONS FROM NON-FERROUS METALS AND ALLOYS

Abstract

This work is devoted to considering the technological features of welding structures made of non-ferrous metals and alloys. It analyzes the main welding methods used in the manufacture of structures made of aluminum, magnesium, titanium, copper, and their alloys (TIG/MIG), electron-beam welding, laser welding, diffusion welding, and friction welding). Physicochemical processes occurring during welding, the influence of various parameters on the quality of the welded joint, and problems related to the formation of defects are considered. Recommendations for choosing optimal welding materials, welding modes, and methods for quality control of welded joints are presented. The work is intended for engineers, technologists, and specialists in the field of welding, and can also be useful for students of relevant specialties.
