Abstract
An overview of laser welding methods and additive technologies used in modern mechanical engineering is given, and the main trends and aspects of these technologies are discussed. Processes of laser welding of thermally hardened aluminum alloys and problems of obtaining high-strength welded joints are considered. The additive growth of heterogeneous materials is analysis taking into account the dimensionless parameters that determine the structure of materials formed using additive technologies.
