Visual-Weld - Heat Treatment

Be able to translate the heat treatment process into a virtual model that can simulate this process and its heat effects; simulate heating, carburization if required, quenching and tempering; assess computed temperature, phase transformations, distortion, and residual stresses; go from geometry to mesh to a simulation model to assessing computed results and generate models that run stable, as fast as possible, still delivering accurate results
Audience
