Abstract
Grades and general characteristic of weldability of new high-strength aluminium alloys, physical-metallurgical processes occurring in their welding, causes of porosity formation and measures for its prevention in weld metal during fusion welding, peculiarities of solidification of welds in multicomponent alloys, as well as formation of hot cracks and measures for their prevention, chemical and structural inhomogeneity are considered. Structural transformations leading to weakening of metal in the HAZ are analysed. Characteristics of new and improved methods and technologies for welding using the electric arc, electron beam and laser heat sources are presented. Keyworks: arc welding, aluminium, alloys, systems of alloying, microstructure, mechanical properties, weldability, porosity, hot cracks, strength of joints, aerospace engineering, transport systems
