Determination and Application of Double Ellipsoid Heat Source Model Parameters

摘要

Based on the double ellipsoid thermal source model, the numerical analysis model of the 3d transient welding thermal process of the GTAW welding stainless steel 0Cr18Ni9 thin plate was established. The method for determining the heat source distribution parameters by the calibration tool of SYSWELD software is given. The finite element solution of the molten pool is compared with the experimental results, and the calculated results are in good agreement with the measured results.
