Abstract

Mathematical dependence accounting changeability in formation of pores at welding and allows expecting probability of implementation of requirements to the diameter of pores from the experimentally found descriptions of the statistical distributing of amount and diameter of pores on the single area of the weld-fabricated guy-sutures is in-process shown out. For the development of mathematical dependence the static laws of distributing of Veybull and Puasson and rule of probabilities increasing were used. Adequacy of the theoretical dependence was tested by calculation of boundary conditions. Obtained mathematical dependence allows on the determination of the fitness of welding processes by the limited amount of experimental information, meeting the requirements at tests on firmness to formation of pores during development of welding materials, at setting of parameters of the welding mode, at the analysis of data about imperfectness in a welding production, at the analysis of possible refuses of process of welding and consequences of such refuses, at the estimation of technological risks in a welding production.
