Welding Simulation

      I am Conducting a WIG welding simulation in Transient Thermal to get temperature as a result and getting it approx 1300 degree Celsius which is fine. Now this result is imported as load in Transient Structural to calculate Residual Stress using mechanical boundary condition as fixed support. The result are not upto the mark as I am getting very low stress. 
      Please help

      I tried increasing the time but no difference in the results

      Hi,

       Can you please check the material properties defined are uniform for both models?

      Thanks,

      Deepak

        Yes actually I saw the change of results when I changed the material from default (Structural Steel) to material I needed 
        Here are the properties of matrials I used

        Please correct where I am wrong 
        Thank You

          I tried the 304L material; the simulation is working fine. Have you added the coefficient of thermal expansion? Please make sure of the consistency of units.

          I guess I missed that part 
          But now after adding it the stress is too much
          how can I lower it

          Value completely depends on the material properties, please check on data or specs for your material.
