AB The present paper expands the knowledge in the field of welding of age hardening aluminium alloys using MIG method. Aluminium alloy AW 6082 (AlSi1MgMn) according to the specification standard CSN 42 4400 was used for the experiment. This type of alloy is used in industrial practice e.g. for medium stressed parts in railway and motor vehicles and in water, oil or petrol pipes. For the purpose of assessing the impact of multiple cycles on the properties in the heat affected zone the weld was designed as a multi-layer weld. The objective of this paper is not only the impact assessment of the degradation of the mechanical properties, but also the possibility of recovery of these properties by heat treatment. During the experiment, the effect of temperature holding time by solution annealing and artificial hardening on the mechanical properties of the base material, HAZ and weld was studied. The effect of heat treatment was evaluated by Vickers hardness test.
