摘要
This paper presents a simulation of laser surface remelting with the SYSWELD finite element method software. Micro-structural changes, increase of hardness, and surface profile modification of the remelted samples are evaluated. The model input file was edited to involve laser track overlapping with a time delay. Temperature field distribution and metallographic phase proportions were extracted from output data in graphical form to demonstrate the influence of repeated melting on phase development in the overlapped region. The stored model is ready to be modified for other materials or process parameters.
