Filed of investigations:

• Nanotechnologies and nanostructured materials for joining high-strength alloys, dissimilar and composite materials based on aluminium using solid-phase and diffusion methods;
• Weldability of new structural materials based on aluminium and magnesium, composite materials with aluminium matrix and similar materials using different methods;
• Nature of postweld hot cracks and development of methods of their prevention in welding of new high-strength complex-alloyed alloys, including alloys of aluminium and magnesium with lithium;
• Interaction of welding pool with gases, development of methods of degassing of molten metal and estimation of influence of porosity of welded joints on their service properties;
• Structural transformations in the area of welding and solution of problems of producing joints of equal strength with base metal;
• Determination of characteristics of service strength and reliability of welded joints and search of methods of their increase up to the level of base metal.

Development and improvement of technologies of permanent joint:

• Pulsed-arc non-consumable welding of aluminium-lithium and other high-strength light alloys of different systems of alloying in manufacture of critical products. Technology improves the quality of welds and increases their strength by 10-15%.
• Pulsed-arc non-consumable electrode welding of thin-sheet structures (1-4 mm) for manufacture and repair of boats, cutters, superstructures of ships, equipment for food and chemical industry, tank-trucks, pipelines and other. The technology provides high productivity of process, decrease of structure deformations and cost of welding.
• Electroslag welding of components of aluminium busbars, wires and billets of large section (of 50-210 mm thickness) in stationary conditions and in site. Electric resistance at the area of a joint does not exceed the resistance of base metal and is characterized by high stability.
• Electron beam, as well as laser welding and surfacing of aluminium alloys for manufacturing large-size shells and vessels and stringer panels, structures of heat exchange equipment, home appliances, pistons with cooling hollows and strengthened grooves for rings. The technology provides high quality and stability of mechanical properties of permanent joints of  thickness from 0.5 up to 350 mm.
• Joining using different methods of dissimilar metals, composite materials based on aluminium with fibrous (steel, silicon carbide, carbon, boron) and dispersion (oxides, carbides, intermetallics) strengthening. Technologies and materials used in ship and aircraft building, aerospace products, electric engineering and welding of aluminium and its alloys with steels, copper and other metals.
• Production of welding wires (fillers) containing high-efficient modifiers Ti, Zr, Sc which provide high technological and strength  characteristics of aluminium alloys joints.
• Manufacture of covered aluminium electrodes of the series UANA for repair welding and surfacing of parts and structures of  wrought and cast aluminium alloys. The composition of coating and technology of manufacture of designed electrodes provide them with welding and technological properties at the level of the best foreign analogues.
