The joining technology of similar and dissimilar materials plays a crucial role in various areas,
include manufacturing. Many conventional welding techniques have been used over the years to
successfully join various materials. Friction stir welding (FSW) is a solid-state welding process.
This thesis discusses the investigation of mechanical characteristics of butt weld joints of aluminum
alloy AA6061 along with AA5083. An experiment was conducted for different tool rotational
speeds of 600 rpm, 1000 rpm and 1400 rpm. Using the vertical milling machine and welding speed
of 40 mm/min. Friction stir welded (FSW) joints of higher tensile strength, lower flexural strength,
and lower impact strength with maximum hardness, for the work piece fabricated at 1000 rpm
using a high-speed steel tool with a cylindrical profile was observed. Better understanding of the
effect of tool rotational speed and mechanical properties was illustrated through the experimental
result.
