Abstract

Generally , Friction Stir Welding (FSW) is a solid-state joining process that commonly uses the frictional heat produced by a rotating tool to join materials. The non-consumable device, profiled probe. and shoulder rotate and plunge into the interface between two workpieces. It then moves along the joint axis , allowing the material to heat and soften.The shoulder also contains this plasticized material (when two part s create heat and start to melt at the contrast area). which that mechanically mixed to form a sol id phase weld . Besides choosing Bobbin Friction. Stir Welding (BFSW) as the high-quality welding. there's a need to avoid the movement of excessive heat to the welding zone and a steady-state heat flow to the Aluminium Alloy tool. So. critical research requires to find the most suitable refrigerant lubrication at the appropriate cooling method. More recently , the scope has increased. On the other hand, significant research has extended in finding a proper cooling rate while using the right cooling method to improve the welded pro ducts. Besides.Ultimate Tensile Strength (UTS) Hardness Testing are conducted to strengthen our research to find the most effective and sustainable solution
