  • Method for producing a gas generator of welded-brazed construction
    Patent number: 6321450
    Abstract: A gas generator is produced of separate units, including a mixing head, a casing and an outlet branch pipe, which are interjoined by welding. The mixing head is welded to the outlet branch pipe through a spacer and a structural spherical casing. The spacer and the outlet branch pipe are made of two inter-brazed envelopes, the inner envelopes of the spacer and the branch pipe are welded at their end faces by electron-beam welding, and the outer structural envelopes are welded by electron-arc welding using a split ring. The spacer is joined to the mixing head by automatic gas-shielded welding. The spherical casing of the gas generator is welded to the outlet branch pipe and the mixing head after the spacer is welded to the mixing head and the outlet branch pipe.

  • Method for producing a multilayer thin-walled bellows of stainless steel
    Patent number: 6222148
    Abstract: The method for prodicing a multilayer thin-walled bellows of stainless steel consists of manufacturing round billets by welding the sheets, packing the round billets into a multilayer bank, corrugating the bank for forming the multilayer bellows and the bellows tightness testing. The round billets are manufactured of the preliminary cut sheets of given dimensions by their electric arc pulsed gas-shielded welding. The packed multilayer bank is welded from two sides over the end faces and subjected to heat treatment by its heating up to the temperature of 1000-1130° C. in the shielding medium and holding at this temperature during 20-45 minutes with subsequent cooling.

  • Method for producing a welded-brazed combustion chamber
    Patent number: 6107596
    Abstract: A combustion chamber for a liquid-propellant rocket engine includes an injector head jointed to a combustion chamber casing having an exhaust head on a nozzle output. The casing is made of a steel jacket and a bronze-steel internal fire wall, which are joined with each other and contain shells connected in series. The exhaust head with shells of the casing, jointed to the exhaust head, are brazed using a solder on the basis of nickel, chromium and manganese. Parts of the injector head and other members of the combustion chamber casing are brazed using a copper-silver solder. Shells of the fire wall are connected by an electron-beam welding, directing an electron beam into axial gaps left while brazing between shells of the jacket. The shells of the jacket are then sequentially connected by an automatic gas-shielded arc welding through corresponding ring spacers.
