Abstract

FSSW is an advanced and popular solid-state material welding method, which has achieved a different variety of popularity in service in industries and automotive. FSSW method (technique) is used for joining similar or dissimilar materials like aluminium, titanium, magnesium and copper alloys etc. This paper presents finite element modeling of friction stir spot welding (FSSW) process using Abaqus/Explicit as a finite element solver. Three-dimensional coupled thermal-stress model was used to calculate thermo-mechanical response of FSSW process. The various factors such as rotational speed, transverse speed and profile of the tool plays a very significant role in the joining quality of material using FSSW. The main target of this analysis is to observe the variation of tool profile and welding quality of Ti 6Al 4V alloy as the tool speed varies. Two Ti 6Al 4V were lapped and provided with support to the bottom of the plate known as a back anvil to constrain the motion. This is where we analyzed the material flow due to friction of heat generation in the weld zone. Ti 6Al 4V is one of the most commonly used materials and its applications, where low density and excellent corrosion is applied in a wide range of resistance, are necessary in industries such as aerospace industry and biomechanical, marine, chemical industries, gas turbine, etc.
