| Abstract Scope |
Essential variables for laser and electron beam welding processes are developed and transferred into a production environment through experimental trial-and-error approaches. To achieve high levels of precision and repeatability during production, welding simulations are beginning to be incorporated to accommodate minor variations in processing parameters. However, the thermophysical properties used in these simulations are often not representative of the composition of the incoming material but are instead compiled from numerous sources studying different materials, introducing uncertainty. Alternatively, thermodynamic simulations can be incorporated to predict composition- and temperature driven variations in these properties. Analysis of these results demonstrated that in addition to Cr and Ni composition, the elements Mn, Si, P, S, V, Cu, and Ti may have noticeable or even overwhelming effects on thermophysical properties of interest. |
