To ensure the competitiveness of high-tech industries, the introduction of new technologies of materials processing is required. The technological capabilities of advanced laser and additive technologies are shown by the example of manufacturing the gas collector of the combustion chamber of the GTE‑65.1 gas turbine unit. The main stages of preparation for the production of high-precision blanks by direct laser deposition from heat-resistant nickel alloy and stainless steel, and their subsequent processing are described. The results of metallographic studies, mechanical tests and geometry control are presented, confirming the high level of quality of the products obtained. The article demonstrates possibility of combining additive technologies, laser welding and cutting technologies, and technologies of thermal, mechanical and electroerosion processing in the manufacture of technically complex assemblies and parts.
