Applied methods were analyzed for producing a permanent joint of thin-wall pipelines of aircraft gas-turbine engines. The peculiarities of application of mechanized and automated joining technologies were noted. The experimental works were carried out for mastering a technology of orbital welding of position butt joints of pipes of up to 0.5–1 mm wall thickness, providing high quality of joints and welding productivity. The developed technology of orbital unsupported pipe welding is used in serial production in JSC «Motor Sich». 5 Ref., 2 Tables, 4 Figures.
