Nowadays, the abrasive water jet (AWJ) technology
is much in use for cutting materials into complex shapes
with high dimensional accuracy. The objective of the present
paper is to study the topography as well as the roughness of
the surfaces in friction stir welded (FSW) joints, machined by
AWJ. It discusses machinability of the FSW joints by AWJ.
Subsequently, this paper makes a critical analysis of the surface
properties by optical profilometer. Top and bottom surfaces,
created by FSW, have also been analyzed using an
optical 3D measurement system to determine the morphology
and topographic parameters. FSW possesses favourable joining
properties and generates a minimum heat-affected zone
(HAZ) because of its comparatively low temperature coalescence.
Three friction stir welding samples were prepared at
500, 710 and 1000 rpm with a welding speed of 40 mm/min
on AA 6101-T6. After analysis, it was found that the sample
prepared at 500 rpm and with welding speed of 40 mm/min
produces a surface fit for industrial applications in terms of
surface roughness and dimensional accuracy. It has also been
observed that unlike other conventional or non-conventional
processes, no HAZ is generated during the cutting of FSW
joints by using the AWJ technology.
