摘要

A computational fluid dynamic (CFD) model of MIG welding of aluminium, which includes the arc plasma, the wire and the workpiece in the computational domain self-consistently, has been developed. The model allows the depth and shape of the weld to be predicted for a wide range of welding parameters, without the need for repeated measurements to determine fitting parameters. A graphical user interface (GUI) has been developed, so that the model can be easily used by welding engineers: the model runs on standard desktop or laptop computers. The model also predicts the thermal history at every point in the workpiece, which is the input information that is required for predicting important weld properties such as residual stress and distortion and weld microstructure. Predictions of weld composition are compared with measurements, and the feasibility of coupling the CFD model to a finite element model of residual stress and distortion is demonstrated.
