Abstract


Presently arc welded structures are extensively used in automobiles, constructions and power plants. As the main cause of weldment failure is design defect and overload, it is necessary to analyze the maximum stresses in the weldment. This work deals with investigation of welded T-joint by Tungsten Inert Gas (TIG) welding process with varying gap and angle between the parent materials to determine the breaking stress under tensile load in the weldment. Finite element analysis is carried out using Ansys software and results are compared with experimental analysis using Taguchi optimization method. Angle, arc force and gap between parent materials are used for the Taguchi optimization technique. The optimized fillet weld section (low carbon steel AISI1020 and copper) is arrived by restricting the weldment failure.
