Spatter model of CO₂ arc welding based on partial least-square regression method

According to the mechanism analysis of short-circuit process, characteristic parameters are extracted from electrical signals to welding process by statistical analysis method with transfer period as the basic analysis unit, in which the process steadiness is reflected by variation coefficient. Partial least-square regression method is suitable because of the close correlation among variables. The experimental result shows that the spatter model is practical which is a new method for analysis of spatter.
