Friction Stir Welding

Friction stir welding is the process of cylindrical – shouldered tool rotates and traverses at pre-determined rpm and velocity according to material either similar or dissimilar along the metal joining line from a plasticized metal results in severe solid state deformation involving dynamic recrystallization of the base material.

The co-efficient of friction and co-efficient of heat generated by mechanical mixing process of the tool and work pieces cause adiabatic heat and plasticize material where clamping force assists in a forged consolidation for metallic bonding.
