The results of the analysis of the requirements for the accuracy of the welding process parameters based on the mathematical model of heat spread in the product from the normally circular heat source (NKI) on the surface of the flat layer. The methodology for determining the coefficients of the model based on experiments to determine the size of the weld is set out. A universal criterion for evaluating disturbances is given - the relative transmission coefficient (OKPV), suitable for both modes and for welding conditions and its calculations for a number of welding methods are performed. Ways to automatically regulate the sizes of the welding bath based on the analysis of the mathematical model. Approaches are proposed that take into account the impact on the accuracy of maintaining parameters of a probabilistic nature of possible disturbances. It is shown that an effective way to ensure the required accuracy is the regulation according to the analytical mathematical model of the NKI.
