摘要： A gas generator is produced of separate units, including a mixing head (2), a casing (1) and an outlet branch pipe (4), which are inter-joined by welding. The mixing head (2) is welded to the outlet branch pipe (4) through a spacer (3) and a structural spherical casing (1). The spacer (3) and the outlet branch pipe (4) 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 (3) is joined to the mixing head (2) by automatic gas-shielded welding. The spherical casing (1) of the gas generator is welded to the outlet branch pipe (4) and the mixing head (2) after the spacer (3) is welded to the mixing head (2) and the outlet branch pipe (4).
