Resumen
The paper discusses the factors affecting the reliability of the welding process. Results of the analysis causes the appearance of defects and deviations from the specified mechanical properties. It is shown that one of the important factors affecting the reliability of the process of surfacing, are electric modes, whose parameters depend not only on established welding - operator, but also on the quality of the supply of electrical energy. The influence of parameters on the reliability of the process in a multilayer cladding.
