Abstract
There is an increase in reducing the weight of structures through the use of aluminium alloys in different industries like aerospace, automotive, etc. This growing interest will lead towards using dissimilar aluminium alloys which will require welding. Currently, tungsten inert gas welding and friction stir welding are the well-known techniques suitable for joining dissimilar aluminium alloys. The welding of dissimilar alloys has its own dynamics which impact on the quality of the weld. This then suggests that there should be a process which can be used to improve the welds of dissimilar alloys post their production. Friction stir processing is viewed as one of the techniques that could be used to improve the mechanical properties of a material. This paper reports on the status and the advancement of friction stir welding, tungsten inert gas welding and the friction stir processing technique. It further looks at the variation use of friction stir processing on tungsten inert gas and friction stir welded joints with the purpose of identifying the knowledge gap.
Highlights
Aluminium alloys are known to be good candidates for different applications in various fields like aerospace, food packaging, automotive industries, etc
One of the most critical factor to consider for tungsten inert gas (TIG) welding is the filler metal, which mainly depends on the alloys to be welded
It is noticed that the common mechanical properties analyzed include the tensile test, fatigue and microhardness
Summary
Aluminium alloys are known to be good candidates for different applications in various fields like aerospace, food packaging, automotive industries, etc. There have been some challenges that were involved in joining dissimilar alloys through TIG technique Those challenges include porosity, solidification cracking, thermal residual stresses, etc. Friction stir processing (FSP) is a technique used to modify the microstructure of a metal through the use of a non-consumable rotating tool.
