    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.
