If you want to learn about the multiphysics modeling of a welding process, then tune into this webinar featuring guest speaker Stuart Brown of Veryst Engineering.
Modeling a complex thermomechanical process, such as welding, requires the inclusion of several coupled physics phenomena.
This webinar describes how multiphysics modeling enabled a simulation of a valve welding process, which was needed to determine how a toxic leak developed. The numerical simulation allowed a rapid bounding analysis of the welding process and generated heat that affected the polymeric seals. The simulation included the physical processes of the deposition of weld metal, melting of the base metal, radiative heating due to the high-temperature plasma arc, and heat of fusion of the solidifying weld as well as tracing the weld path at different amounts of material deposition and sizes of fusion zone.
During the webinar, we will show how to create the model in the COMSOL Multiphysics® software, describe the actual toxic release event, and discuss the testing that was done to correlate with the numerical simulation results. The webinar will conclude with a Q&A session.
