MATHEMATICAL MODEL OF MOLTIEN POOL AND ON-LINE OPTIMIZATION OF WELDING PARAMETERS

The key to a successful calculation and prediction of welding process by mathematical model method is the selecting of an appropriate model and its parameters. This paper introduccs an infra-red means employed to identify the mathematical model parameters of molten pool. The results, of experiments show the identified model essentiall represents the way of molten pool forming. The welding parameters selected on the basis of the model may give fairly satisfactory results in the requisite pool. size.
