The article shows the necessity to have information about the real relief formation in the coupling zone in various welding methods and regimes in order to estimate the local strength of fillet-welded joints. It is shown that the existing method of radii and coupling angles selection leads to significant errors, and in some cases is controversial. A technique for experimental investigation of the geometric parameters of the coupling zone is proposed. The regularity of dispersion of radii and transition angles for various technological methods and welding regimes is established on the basis of statistical processing of a large array of experimental data. The study of the established regularities for ergodicity and stationarity made it possible to assume that the geometrical parameters of the coupling zone of fillet-welded joints being made with similar welding regimes will be repeated.
