近年来，光滑粒子流体动力学(SPH)方法在焊接过程建模中的应用日益广泛，但对该方法的定量预测能力却知之甚少。提出了一种新的用于模拟钨极惰性气体保护焊(TIG)点焊过程的SPH模型，并将我们的SPH实现与两种基于有限元(FEM)的模型进行了深入的比较。为了能够定量地比较我们的SPH模拟方法和基于网格的方法的结果，我们还提出了一种改进的基于线性最小二乘的粒子到网格的内插方法，该方法带有可选的孔洞填充通道，该通道考虑了缺失的粒子。我们表明，SPH方法能够产生很好的结果，特别是考虑到所调查的有限元方法之间的观测偏差，因此，我们在工业相关的工程应用中验证了该方法的准确性。
While the application of the Smoothed Particle Hydrodynamics (SPH) method for the modeling of welding processes has become increasingly popular in recent years, little is yet known about the quantitative predictive capability of this method. We propose a novel SPH model for the simulation of the tungsten inert gas (TIG) spot welding process and conduct a thorough comparison between our SPH implementation and two finite element method (FEM)-based models. In order to be able to quantitatively compare the results of our SPH simulation method with grid-based methods, we additionally propose an improved particle to grid interpolation method based on linear least-squares with an optional hole-filling pass which accounts for missing particles. We show that SPH is able to yield excellent results, especially given the observed deviations between the investigated FEM methods and as such, we validate the accuracy of the method for an industrially relevant engineering application.
