Abstract |
From the point of estimating the energy input forming a single welding pool, the experience of industrial application of micro-plasma powder welding deposition (MPWD) in large-scale repair of aircraft gas turbine engine (GTE) blades made of JS32 nickel-based superalloy has been analyzed. For some welding mode types, used in industry for the last 10 years, the conditions providing technological strength of “substrate-deposited metal” welding joint in bandage shelves refurbishment have been specified. Pecularities of a number of technological factors affecting heat-input into the work piece at the stage of a single weld pool existence have been examined, proposing future directions for MPWD process optimization. Index Terms- Aircraft Gas Turbine Blades Repair, Hot Cracking Susceptibility, Microplasma Powder Welding Deposition, Nickel Superalloys, Weldability, Technological Strength. | |||||||||
