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.
