Abstract
Structure of cast blades in the as-welded and heat-treated condition has been studied. Austenising of joints prior to welding provides their heat resistance (900 oC) at a level of base metal. Experimental examination of structure of regions in gas turbine engine blades repaired by welding and brazing has been conducted.
Keywords: argon-arc welding, arc brazing, nickel alloys, welded joints, filler materials, eutectic phase, heat treatment, heat resistance, microstructure, repair of blades
