Abstract
It was determined that area of application of pulse welding power sources for processes of metal flame treatment can be expended. At that continuously rising in price natural gas is substituted by hydrogen-oxygen mixtures or hydrogen. Application of nickel instead of low-carbon steel as electrodes at water electrolysis allowed reducing process voltage to 2.1 V. Dependence of increase of percent content of finer powder fractions (1-50 mm and 1 mm, and less) at increase of frequency of current of anode dissolution was determined. Received results indicate perspectives of investigations in this direction for increase of efficiency of electrochemical processes of hydrogen production as well as micro- and nanopowders for manufacture of welding and brazing powder consumables. 12 Ref., 3 Figures.
 
Keywords: power sources, pulse frequency, generators of hydrogen-oxygen mixtures and hydrogen, micropowders of metals, process efficiency
