Re: [MW:11544] Re: welding simulation

Ashish yadav, can you tell me is the SYSWELD Software available on for downloadable? or do we need to buy it from recognised company?
 Can it be used for simulation for two different grade of steel?

Pleasse reply

Hello K.Babu
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..
