A welded assembly of combustion chamber elements. Two subassemblies of the combustion chamber are fabricated by butt-welding, and a first subassembly has an intermediate connection ring welded thereto suitable for performing final welding with the second subassembly.
Claims10
A method of fabricating a combustion chamber essentially made up of welded-together shells, the method comprising:
- making separately two subassemblies of such shells by butt-welding the shells together, with an intermediate connection ring being welded to one end of a first subassembly, the intermediate ring including an assembly surface;
- engaging one end of a second subassembly on said surface;
- and
- welding it to said intermediate ring.
A combustion chamber constituted by a plurality of preformed shells including a chamber end wall that are assembled together by butt-welding, with the exception of a junction between two subassemblies of said shells, said junction being made with an interposed intermediate connection ring.
