FIELD: methods of production of braze-welded structures; may be used in manufacture of rockets, in particular, manufacture of liquid-propellant rocket engines. SUBSTANCE: method includes automatic arc welding with use of consumable and nonconsumable electrodes with or without fillers, in medium of helium or argon shielding gases, or in their combination; manual welding; electron-beam welding and brazing applied in different combinations for joining of units comprising the stator. EFFECT: prevention of formation of cracks due to manufacture of stator parts from steels with large volume of polymorphic transformation, from copper alloys required definite conditions for their welding. 6 cl, 11 dwg
