The article is devoted to studying the influence of technological parameters of electrochemical dimensional processing mode on the structure and physical and mechanical parameters of the die engraving working sections, which made it possible to recommend this method as a finishing operation in the manufacture of forging dies.

This article presents the results of studies of the high-voltage electrochemical cathodic process of cleaning the welding wire from scale, rust and other contaminants, since the quality of the weld significantly depends on its condition. The es-sence of high-voltage electrochemical cleaning is described, according to which electrolyte is supplied to the treated surface of the workpiece by a narrow stream from the holes of the sprayer nozzle. The description of the experiments is given. The authors note the influence on the stable course of the cathodic process and the quality of cleaning of the electro-hydraulic and technological parameters of the process. They determined the absence of the welding wire hydrogenation, which is explained by the specificity of phase transformations in the near-cathode zone. Rational regimes for cleaning the welding wire are given.

The article is devoted to the study of the influence of regime parameters at electrochemical dimensional processing on the microhardness of titanium alloys, its connection with the gas saturation of the surface layer and the change in depth.
