This article presents a novel variant of conventional friction stir welding (FSW). This welding process involved in chemical and pharma industries with numerous applications like low level joining process. Moreover, in this article investigate about effect of electrical enhancement with friction stir welding is studied by using commercially available finite element analysis solver ANSYS. In this investigation 2D axis symmetric thermal, thermoelectric and thermo mechanical finite element model is developed to analyse the mechanical behaviour of electrically enhanced friction stir welding process of stainless steel plates by using tungsten tool. It is compared with conventional friction stir welding by using commercially available finite element analysis (FEA) solver ANSYS. In conventional Friction stir welding (FSW), joining of higher harder material results in high tool wear, tool breakage and low weld speed during plunge stage to gain heating to plastically soften the work piece. High harder material has problem of high tool wear, tool breakage and low weld speed during plunging stage because material is cold during plunging stage, therefore more axial force is required to plastically soften the work piece. Electrically enhanced friction stir welding (EHFSW) is one of the new technique in which electric current is passed to work piece from top of the tool. As electric current is passed from the tool, work piece get localised heating which will help material to reach the plastic stage quickly when tool rotates over it, so tool can easily plunge into work piece, which will reduce axial force acting on tool therefore tool wear and tool breaking problems can be minimized and weld speed can be increased. This finite element analysis results shows axial load acting on tool can be reduced when electric current is passed therefore reducing the tool wear, tool breaking and increases weld speed.
