The paper gives the results of investigation of the features of formation of D16 aluminium alloy welds in consumable electrode welding with application of two insulated fi ller wires or embedded elements of diff erent chemical composition. Wires of Zv1201, ZvАК5, ZvАК12 grades of 1.6 mm diameter and embedded elements cut out of V92, V96 and 7056 alloy blanks with diff erent content of zinc were evaluated. It is shown that ZvАК5 wire ensures reduction of the length of solidifi cation cracks and quantity of pores in welded joints, and welded joint strength becomes higher at addition of zinc into the welds. 15 Ref., 5 Tabl., 5 Fig.
Keywords: aluminium alloy, arc welding, consumable electrode, welded joints, fi ller wires, structure, solidifi cation cracks, mechanical properties, investigations
