METHOD OF PRODUCTION OF GUN BARREL Russian patent published in 2015 - IPC F41A21/02 F41A21/22 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to military technology, namely the technology of production of gun barrels. The method of production of a gun barrel consists in the fact that the solid blank on the length of the barrel is cut along the horizontal axis. In each part of the blank a recess is cut for the bore, the surface of the recess is machined. The prepared surface is coated by the method of argon-arc welding in combination with the self-propagating high-temperature synthesis. The non-consumable electrode is used as tungsten-rhenium, and the filler electrode - as the electrode of compacted exothermic mixture of titanium powder with boron and/or carbon. After welding the finishing treatment of horizontal surfaces of the blanks and the surfaces of welding of recesses is carried out to the desired calibre of the barrel. Connection of the treated blank parts to each other to the barrel is carried out on the outer surface by winding with interference in layers of high-strength steel wire or ribbon, or a ribbon of carbon fibre.

EFFECT: reducing the weight of the gun, reducing the bending vibrations of the barrel, increasing the durability of the coating while maintaining high service characteristics.
