    Abstract: Within examples, a method of manufacturing a double-walled titanium conduit is described. Example methods include stitch welding multiple concentric sheets to form a stitch layer (902), providing the stitch layer between an inner wall and an outer wall of the double-walled titanium conduit (904), circumferentially seam welding the inner wall and the outer wall to the stitch layer to create a welded assembly (906), die forming the welded assembly at temperature and pressure to form inner structures between the multiple concentric sheets according to stitch welding lines and to enable a diffusion bond process among the inner wall, the stitch layer, and the outer wall (908), and removing the double-walled titanium conduit from the die (910).

    Abstract: A method of nano-welding of metal pipes is described, wherein, in the first stage, the preliminary preferably mechanical processing of the front surfaces of pipes by the help of the cutter is made, in the second stage, the front surfaces of metal pipes are covered with hydrocarbons preferably liquid or in the form of pastes and gels, which protect against oxidation, and then their faces are connected, previously centring, preferably by applying a compressive force, 1-7 kg / mm 2 , and next the contact areas are heated up to achieve a temperature of about 0.75 to 0.95 of temperature of melting point of the metal, wherein after reaching a heating temperature of Ac3 point of the iron-carbon diagram of value depended on the type of steel, an additional pressure force is used-preferably about 1-2 kg / mm 2 .
