Abstract
The paper deals with the features of weld formation in fusion welding of aluminium alloys under the impact of hightemperature heating, and friction stir welding, ensuring weld formation due to plastic deformation of the metal in the welding zone. Technological sequence of friction stir welding process is given and the main principles of its implementation using the designed laboratory unit are described. Strength and ductility indices of welded joints on sheet (1.8–2.4 mm) high-strength aluminium alloys produced by nonconsumable-electrode argon-arc and friction stir welding have been analyzed.
Keywords: friction stir welding, aluminium alloys, nonconsumable electrode argon-arc welding, hardness, bend angle
