Thanks for your support.
Its good that you have worked in sysweld. I am also doing a project to
simulate a Laser weld joint of two SS plate having dimension100*400mm
of 2mm thickness. weld run is of 400mm by putting plates together with
2mm thickness.
In heat model I have taken 3D conical gaussian heat source for the
laser source. Arc efficiency is 60% and for cooling rate, I have used
predefind convective and radiation(mm).
After that I solved for the thermal and mechanical results. In thermal
results temperature contour, phase proportion and grain size is there.
In mechanical results, thermal stress, strain, strain energy is there.
Now I can not understand that how i will justify this results. Should
I go for the experiments or some standards are there?
Please help me..
