Estimation to Optimize Energy Spent on a Single Welding Pool Creation in Micro-Plasma Powder Deposition Process of Js32 Nickel Superalloy HPT Blade’s Bandage Shelve

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 workpiece 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.
