Numerical analysis of thermal conditions for planning and further improvements of hard surfacing experiment

Abstract

An initial goal of this study was to use the results from an existing experiment and to set up as complete as possible the numerical model for the thermal analysis of a hard surfacing process. It was clear from the start that the process is complex since it includes multiple weld passes, or several layers, which are elements difficult for experimental or numerical thermal modeling. When the design parameters for the set up of the numerical model have been identified, it was noticed that some of them were only partially recorded in the experiment. Conclusion was that it will be valuable to highlight those very necessary parameters. © 2013 AIP Publishing LLC.
