The friction stir welding (FSW) is used in many industries like aerospace and automobiles etc due to many advantages like no chance of formation of second phases, porosity, brittleness and cracking. It comes under category of solid state joining method since materials are joined below their melting point temperature. So, its vast applicability in industries there is a need of a machining process which can produce complex shape products with exact dimensions. For this a problem i.e. generation of heat affected zone (HAZ) is encountered during cutting by any conventional and non conventional cutting method. So, abrasive water jet (AWJ) cutting method is suitable to cut FSW joint without generation of HAZ. In this paper Friction stir welded joint is prepared for aluminium alloy AA 6101-T6. Then comb profile is cut by AWJ cutting method. The surface which is exposed to water jet is analysed under field emission scanning electron microscope (FESEM) to study the surface morphology. Three distinctive zone i.e. initial damage region (IDR), smooth cutting region (SCR) and rough cutting region (RCR) is observed under FESEM.
