A technology for manufacturing a steam turbine blade packet made of heat-resistant high-alloy hard-to-weld steel of a martensitic class is offered. The advantage of electron-beam welding use at the assembly of a blade packet instead of a common electric arc welding method in protective environment is described. A technological tooling specially designed essential for welding process automation is considered. There are shown results of laser scanning a blade packet geometry with the aid of NikonM
