in this study, it has been tried to understand the tool shapes and parameters play an
important role to determine the tensile strength of weld joints by FSW.
Kush P. Mehta and Vishvesh J. Badheka (2016) reported maximum irregular and
large copper particles in welds made by triangular pin proles. Polygonal pin shape
has defects such as fragmental cracks and voids irrespective of its static and dynamic
areas. The defects decreased with the increase in polygonal. Defect-free macrojoint
was reported for cylindrical tool pin prole.
