Title

Effect of Tool Rotational Speed on the Tensile and Microstructural Properties of Friction Stir Welded Different Grades of Stainless Steel Joints

Pages

  141-147

Abstract

 Friction Stir Welding is a relatively new solid state joining process, which is suitable for welding similar and dissimilar materials. The present research work concentrates on the effect of Tool Rotational Speed on the tensile, Microstructural Properties and Microhardness of the friction stir welded joints of different grades of austenitic Stainless Steel sheets. Four different Tool Rotational Speeds are used in the experimentation while the other process parameters like traversing speed and the tool tilt angle are kept constant. The tensile testing, micrography and Microhardness measurements were carried out in the welded samples. It is observed from the results of tensile testing that the joint made at the Tool Rotational Speed of 1320 rpm has the maximum strength among the experimented speeds. The measured Microhardness values at heat affected zone and parent metal zone have shown higher hardness than the weld zone. Fine and equi-axed grains are observed in the welded region at all experimented speeds with a negligible amount of transformation of austenite into martensite. These results have impact on the development of welding procedure for dissimilar Stainless Steel Friction Stir Welding process.
