Aluminum 6066 is widely used for applications such as aircrafts and boat and ship building. Thusconsidering the applications, the joining of the metals must be such that minimum residual stresses anddistortion must occur. Two different welding methods i.e. Stir friction welding and metal inert gas welding(MIG) have been compared by making a butt type of joint. Investigations have been carried out to comparethe mechanical properties i.e. tensile strength, hardness and micro-structural properties. The resultsobtained showed that FSW welded joint possessed greater tensile strength and hardness whereas there wasa general decay in the mechanical properties for MIG welded joints. The micro-structural images under SEMshowed that the HAZ region for FSW welded joint is narrower than that for MIG. This is because of the hightemperatures during MIG. Thus considering all these factors FSW is an optimum process for industrialapplications as it saves energy and does not show any fusion related problems.
