Optimization of process parameter of wear behaviour in friction stir welded Aluminium AA6101- T6 Alloy Taguchi Method

Resumen

Due to the high electrical conductivity of aluminium alloys, they find widespread use in sectors
dealing with electricity. A common use for AA6101-T6 is in electrical bus bars. The
conductive area has shrunk as a result of the mechanical fasteners used to unite the various
alloys that make up the electrical bus bars. In order to prevent this issue, it is recommended
that they be linked without any metal or their qualities being removed. The friction stir welding
process is primarily researched for its wear characteristics on specified joints made of
aluminium alloys with identical compositions. Within the scope of this study, AA6101-T6
aluminium alloys were subjected to friction stir welding by adjusting the tool's transversal
speed, rotating speed, and tilt angle respectively. In order to investigate the influence of the
aforementioned factors on the mechanical characteristics of welded joints, an analysis of
variance was carried out. Based on the findings of the experiments, it has been determined that
a welded joint with the combination of a rotating speed of 180–200 rpm and an axial force of
20, 30, or 40 N offers superior mechanical qualities. According to the results of an analysis of
variance, the most significant influence on tensile strength and micro hardness is created by
variations in the tool's rotating speed, while the most important impact on wear strength is
made by variations in the tool's tilt angle.
