摘要： A method of manufacturing nonconsumable copper-zirconium electrodes in two stages. First, an intermediate layer of cold-deformed copper of a thickness substantially equal to the diameter of a zirconium core is cold deformed on the core. Second, a copper sleeve of an external diameter 5 to 15 times greater than the diameter of the core is hot deformed on to the first structure. Using this method ensures proper circular shape of the core in cross-section, reliability of the bond between the core and sleeve for operation of the electrode at temperatures in excess of 1000.degree. C and at cooling water pressures as high as 10 atmospheres, high thermal and electric conductivity across the copper-zirconium interface, as well as fine technological effectiveness of the process to the conditions of large-scale production.

摘要： A torch with a turbulized supply of a plasma forming gas comprises an electrode having a high-melting insert and a flat end face, and a nozzle with an internal surface having two mated portions: one cylindrical and one tapering; and the diameter of the electrode flat end face amounts essentially to 0.4-0.5 diameter of the electrode proper and the radius of conjugation of the nozzle cylindrical and tapering portions is equal essentially to the length of its cylindrical portion. Due to such a design, the inventive torch features a long service life of both the electrode and the nozzle.
