- ABSTRACT: Methods which use to produce specialized holes by the process of perforation of aluminum-magnesium foil are considered. Defects of mechanical and laser perforation of aluminum foil are shown. A fundamentally new design of waterjet-laser head are represented. This construction allows obtaining specialized holes comparable to the profile of the jet stream that is formed by an annular nozzle. Using FlowVision software, mathematical modeling of liquid stream through cavities of newly projected waterjet-laser head, the special feature ofwhich is the presence of ring nozzle head and valve type device, was run which allows liquid inlet into the cavity of the head, using the required amount of points (from 1 to 6 channels of working liquid inlet). Velocity profiles are achieved, the analysis of which allows making conclusions about quality appreciation of inequality of speed fields from the amount of liquid input channels.
