  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.
