Abstract:

This paper considers mechanical properties of the welded joints of aluminium alloy AW6082 under varying metal inert gas welding conditions, determined by tensile and microhardness tests. The test joints were produced at different welding current and welding speed. Cross sections of the welding zones have been analysed. The influence of heat input on the tensile strength properties and hardness of the base metal, heat affected and fusion zones were studied. The behaviour of double-V butt weld joints was investigated by tensile tests. Static tensile test and metallographic examination results showed minimum strength in the heat affected zone (HAZ). It was found that the lowest hardness values were obtained in the fusion zone and near the fusion line where rupture occurred.
