The methods of experimental planning and regression analysis are used to obtain the dependence of relative efficiency as the function of discharging circuit, discharge gap’s length and water electronic conduc- tivity parameters. It is shown that the regression equation may be used as interpolation model to compute the relative efficiency with changing of each of independent variables. To increase energy-conversion efficiency of elecrohydraulic pulse treatment for welded constructions in conducting water the corrected from of calculation including correction coefficient is proposed.
