摘要：
In this paper, numerical simulation of distortion and phase transformation in laser welding process is carried out. A coupled thermal-structural and metallurgical model of laser welding process is simulated by using FEA engineering software MSC Marc/Mentat. The specimen model is simulated in the form of butt joint plate with dimension 50 mm in length and 25 mm in width with 2 mm thickness and using material low carbon steel (C15). Conical heat source model implemented in this simulation due to existing Goldak's double ellipsoid commonly used for arc welding process. Phase transformation is predicted based on Seyyfarth-Kassatkin Model and implemented in user subroutine PLOTV which is written in FORTRAN programming language. Presented results of laser welding simulation included temperature distribution, phase transformation, and estimated welding distortion.
