A specific feature of the structure-forming elements used for the manufacture of porous mesh materials is a high specific surface area and a complex configuration of wire meshes, which excludes the possibility of using wire cutting for welding. The research shows that cleaning in Freon-113 is an effective way to remove mineral oils, paraffins, fats and some other contaminants from the mesh surface, since this solvent is stable, non-flammable, non-explosive and does not interact with the workpiece material. In addition, improving the quality of mesh cleaning is achieved by superimposing ultrasonic vibrations in the range of 20...40 kHz. The study introduces flow layouts for the porous materials manufacture by pressure welding of wire meshes from steel 12Kh18N10T and titanium alloy VT2. Findings of the research show that welding envelopes of meshes made of steel I2XI8HI0T by rolling in evacuated makes it possible to obtain porous elements with sufficiently high mechanical and technological properties. It is possible to implement this process on any sheet rolling mill, which is its significant advantage. The paper gives the modes of welding by rolling and diffusion welding of meshes in the manufacture of porous materials. Within the study, we developed a mathematical model that makes it possible to predict the ultimate interlaminar strength for given values of technological parameters of the processes for manufacturing sheet blanks. It is proposed to control the interlayer strength by comparing the calculated data and the results of testing the samples for separation in accordance with the developed methodology. It is advisable to evaluate the control of strength, plasticity in the sheet plane and their anisotropy by comparing the calculated data and the results of testing specimens under conditions of biaxial tension, implemented during hydrostatic buckling through a round matrix.
