摘要：

AZ31 magnesium alloy which are difficult to join by the traditional fusion welding techniques because of the production of porosity in the joint resulting in the weakening of its mechanical properties have been fabricated by friction stir welding. The friction stir welding is a technique that welds the work piece in solid state. During friction stir welding process the heat is generated by friction. Post weld heat treatment (PWHT) is carried on the work piece after friction stir welding is done. Metallurgical and mechanical characteristics of AZ31 magnesium alloy after post weld heat treatment is determined. At a rotational speed of 1100 rev/min and transverse speed of 48mm/min the yield tensile strength of 128.1MPa and 162.2 MPa ultimate tensile strength of this joint achieved. The influence of the welding parameters on the welding quality was shown by the result. Stainless steel of grade 24 (SS24) was used as a stir tool. Joining of the two AZ31 magnesium alloy plates by Friction stir welding is done successfully.
