EVALUATION OF ELECTRON BEAM WELDED JOINTS PROPERTIES OF ADDITIVELY MANUFACTURED AND CONVENTIONAL ALUMINIUM ALLOYS

Presented paper is focused on the experimental welding of aluminium alloys – the additively manufactured material AlSi10Mg and the conventional alloy AW-5754. The experimental electron beam welding was conducted in collaboration with First welding company, Inc. The objective of the experiment was to create a weld joint between aluminium alloys prepared by additive and conventional methods, evaluate the base materials, the heat-affected zones (HAZ), and the weld joint in terms of microstructure, as well as measure and assess microhardness.
