Abstract
This invention relates to a method for the manufacture of a gas-turbine combustion chamber which consists of individual wall sections produced by casting. To make up the combustion chamber, the wall sections are joined by laser welding. Preferably, the individual wall sections are segments of the annular or circular combustion chamber, with the casting material of the wall sections being a high-temperature nickel-base casting alloy.
Claims16
A method for manufacturing a combustion chamber of a gas-turbine engine comprising:
- casting a plurality of individual dome and ring wall sections of a combustion chamber of gas-turbine engine, wherein the individual dome and ring wall sections are from a same highly-temperature resistant nickel-based casting alloy;
- joining the individual cast dome and ring wall sections by laser welding to make up the combustion chamber;
- wherein the welded joints have a thermo-mechanical strength substantially the same as the individual cast dome and ring wall sections.
