Abstract
Welding is an unswerving and competent metal joining process broadly used in industries. Residual stresses and distortion are most important challenges to the safety of system and constructions of butt-welded joints. The difficulties of the archaic measurement of residual stress are time intense and destructive. A three-dimensional fleeting thermomechanical analysis of butt-welded joint has been performed using FEM method in two steps to forecast the residual stresses and distortion. The first step is fleeting thermal analysis that yields dynamic temperature distribution throughout weld and the plates. The next step is the mechanical analysis which yields the residual stress, strain and displacement. It comprises of moving heat source, metal plasticity and elasticity has done during the material deposition, temperature dependent on material properties, element true and death technique was used for filler metal deposition in ANSYS software.
