It is shown that a significant factor limiting the use of porous powder materials for the manufacture of die-welded products is low tensile plasticity and insufficient weldability. Porous meshing materials (PMM) made of steel 12Cr18Ni10Ti (X10CrNiTi18-10) have the necessary technological and operational properties for the manufacture of permeable die-welded elements. The conditions for the formation of a weld in PMM fusion welding are affected by the porosity and the ratio of the thermal conductivity coefficients along the thickness of the welded edges and in the direction perpendicular to the movement of the welding source. Technologies for argon-arc welding of a heat exchanger-evaporator sleeve, electron-beam welding of filter elements with a housing, which are implemented in the manufacture of preproduction models, have been developed.
