Aa6061 Aluminium Alloy

Aluminium and its alloy has very wide area of application i.e. aerospace, automobile and structural industries. The present investigation aimed to study the effect of MIG welding on microstructural and mechanical properties of AA6061 aluminium alloy. The characteristics of fusion zone is typical coarse columnar grains structure because of the prevailing thermal conditions during weld metal solidification. In this work, plates of 5mm thickness have been used as the base material for preparing single pass butt welded joints at different-different current values. The filler wire used for joining the plates is AA4043 (Al-5%Si by wt.) grade aluminium alloy. From this investigation, it was found that the hardness of fusion zone was degraded significantly due to usage of lower hardness filler metal. The precipitation evolution in the heat-affected zone was characterized by XRD which improves the tensile properties of the welded AA6061 alloy.

Active Soldering

Active soldering is an emerging technology of joining a range of materials, which utilizes Sn-Ag composition solder alloy other than conventional Sn-Pb solder, along with reactive element additions (like Ti, Ta, Hf and Zr). In the present study, active soldering is employed for bonding AA6061 aluminium alloy using S Bond 220-50 and S Bond 220M active solders. Soldering was achieved by direct active soldering of AA6061 plates each other using S Bond 220-50 and PEO coated AA6061 aluminium alloy using S Bond 220M, taking into consideration of the application of active solder alloy in joining ceramics. Mechanical properties were evaluated using hardness and lap shear test. Microstructure analysis is carried out by SEM microscopy. The soldered area is examined using EDS giving fair idea regarding the composition of elements present in the solder. It is observed that direct bonding of aluminium alloy using S Bond 220-50 showed better bond strength and hardness when compared with joining using S Bond 220M of the PEO coated aluminium plate.
