Corrosion is always a limiting factor for deciding life of a material. The 6xxx series Al alloys are consideredto have better corrosion resistance compare to other grades. Even then welded samples has some effect of pitting in saltbath. In present paper the welding of plates was carried out using a well-known solid state welding process called asFriction Stir Welding (FSW). The process is widely used for joining Al alloys in marine, aerospace, automobile andrailway industries. The welding was carried out on conventional milling machine with different tool rotational speedsand traversing speeds. The corrosion tests of base metal and welded samples were carried out in 3.5% NaCl solution atroom temperature using cyclic polarization measurement. The pitting effect at different zones like heat affected zone(HAZ) and thermo mechanically affected zone (TMAZ) was studied and results were presented graphically. The impact ofprocess parameters was observed on corrosion resistance after FS welding than base metal. The materialcharacterization of welded samples was also done.
