TITLE :THE EFFECT OF TOOL ROTATION ON MECHANICAL PROPERTIES OF FRICTION STIR WELDING OF ALUMINUM ALLOY
Abstract: Manufacturing sector is rapidly increased after the 2nd world war across the worldwide. In today’s world it is essential to compete with the world to improve the manufacturing sector. Present era is known as the fourth industrial revolution across the globe where modern technologies like; Artificial Intelligence is used in manufacturing sector this technology maximize the output with minimum error. Various type of operation are operated with the help of Artificial Intelligence. These technologies also define which type of material is suitable for tool manufacturing. Due to this specific material is used for tool manufacturing. This factor is increase the life of the tool which is used in FSW process.
The pattern of variation of percent elongation of the material, which is to be welded. Initially the Tool Rotation Speed (TRS) is constant at Welding Speeds (WS), at the certain limits when WS is increased the percentage of elongation of material is also increases for all TRS values. Further when the welding speed(WS) of material is increased beyond a certain limit the percentage of elongation of the material which is to be welded is decreased. This elongation is define by various factors like microstructure of grain, size of grain, tensile strength of the material etc. The increased welding speed causes heating of the tool due to this factor tool life is also reduced. If proper heat is not provided during the operation resulting in poor flow of plastic and clustering of precipitates. This reduces percentage of elongation material, which is welded.
Keywords: FSW process, Rotation of Tool, Tool Speed, various properties of tool, Aluminum alloy.
