Friction stir welding is used as a solid state joining process for soft materials such as aluminium alloys and also for hard materials like steels. It avoids many of the common problems obtained in fusion welding. In mechanical, civil, automobile, naval, and aeronautical engineering beams are widely used of the magnesium alloys for different applications and that are joined by conventional inert gas welding process. Magnesium has less density and low melting point so due to that large heat generation in the conventional welding process so adaptation of new welding process is essential. By using frictional stir welding process enhancement of weld is observed under different mechanical testing which improves weld quality. Also by using different tool size; we implement new techniques of weld.
