The study shows that in order to produce filters capable of purifying liquid or gas from
mechanical pollution it is reasonable to apply porous sheet materials manufactured by
means of roll welding in the vacuum-treated envelopes of the briquette which comprises
square mesh grids made of steel 12Х18Н10Т. We have developed a technique for design-
ing the processes of manufacturing articles made from porous materials. Based on this
technique we have developed a mathematical model of the stamp-welded filters manufac-
turing process. These filters ensure the required precision of purifying liquid or gas from
pollution at preset discharge characteristics. The article defines the optimal values of the
technological processes parameters for manufacturing the porous-net materials with
specified properties, sheet pressworking of filtering elements of the required sizes and
electron-beam welding of sub-components. The results of the stamp-welded filters bench
tests showed that such technological processes help to obtain the products that complete-
ly meet the technical requirements.
Keywords: filter, nominal precision of purifying, operating environment, mechanical pol-
lution, porous-net material, roll welding, wire cloth, sheet pressworking, filtering ele-
ment, electron-beam welding
