dc.description.abstractThe aim of this work is to study the metallurgical and mechanical properties of dissimilar assemblies of 2024 T351 and 6082 T6 aluminum alloy by the TIG process. Aluminum alloy 6082 T6 is well weldable by classical fusion welding processes (MIG and TIG), while aluminum alloy 2024-T351 is almost non-weldable. Base metals were sheets with a thickness of 8 mm. The assembly of the plates was carried out by filler wire of an aluminum alloy type 4043A (AlSi5) with 2 mm of diameter. For the welding of these two Al alloys by TIG welding process in argon a shielding gas. The microstructural evolution across the welded joint dissimilar AA6082-T6 to AA2024-T351 aluminum alloy was characterized using optical and scanning electron microscopy (SEM). The hardness welded joint is the smallest in the melted area and the biggest on the side of 2024 alloy in HAZ. The fracture surface section of the tensile specimen is in the HAZ zone on the BM side - 6082-T6. The tensile strength of the welded joint is 166 MPa compared to 310 MPa for alloy 6082-T6 which is a weaker welded joint material, i.e. the reduction is about two times.
