Abstract

Optimal conditions of laser welding providing qualitative welded joints are established. It was revealed that mechanical properties of aluminium alloys are influenced favourably by specific macro-heterogeneity of the structure of welded joint. Based on the investigations for 1460 alloy, filler wire can be recommended.
