Numerical Analysis on the effect of welding parameters in TIG welding for INCONEL 625 alloy

At present scenario, INCONEL alloy 625 becomes widely used material in aero industry due to its High tensile, creep, and rupture strength, outstanding fatigue and thermal-fatigue strength, oxidation resistance, and excellent weld ability properties. In present work, the plates of 50mm×50mm×3mm are modelled and assembled for v-butt joint using solid works. This model is imported in the FEA software (ANSYS) to carry out the transient thermal analysis. The analysis is carried out with different combinations of welding parameters such as voltage, current, velocity, speed and melting efficiency. From the analysis result, the temperature distribution at various locations around the weld bead is evaluated. From structural analysis result, the distortion of work piece due to the thermal effect is analysed.
