4 Conclusion
After done by the detailed investigation, the mechanical properties and the effect
of friction stir welding parameters of two different aluminum alloys on AA
6082–AA7075 were successfully evaluated. Hence, we accomplished the following
conclusions,
• The tool rotational speed and tool pin profiles play a vital role in getting the quality
of the weld joint.
• The grain size and density of the weld specimen are to decide the joint strength
and efficiency.
• The cylindrical tool pin profile produced successfully defectless weld joints with
a low amount of flash during the joining process.
• The ordinary cylindrical pin profile (Straight cylindrical) gives the greatest tensile
strength value of the weld joint in the tool revolving speed of 1300 rpm and the
tool traveling speed is 60 mm/min.
• The amongst hardness value of the weld joint is obtained by the straight cylindrical
pin-shaped tool at revolving speed is 1000 rpm and the tool traveling speed is
20 mm/min.
• Further, the particle size (grain) of the nugget zone is much better while comparing
with parent material which strengthens the weld pool area.
