The article presents justification for the need to design and develop porous mesh materials to replace the fine-mesh metal single-layer mono-grids used in various technical structures. Evolution of the porous mesh materials composition is described depending on the technical requirements imposed. It is noted that a special role is given to the requirement to the method of connecting the porous mesh material and the main structure of a technical product in terms of reliability, tightness and absence of harmful effects on its internal structure. It is demonstrated that this requirement is successfully implemented in composition of the combined porous mesh material (metal) with edges specially prepared for using the joining method based on the laser pulse welding. Examples are provided of the use of welded structures based on combined porous mesh material in space, aviation and gas industries in the Russian Federation. Current problems of specialized production of the porous mesh materials are considered, and recommendations are provided that should assist in overcoming these.
