Le alloy iyingxubevange ye-nickel-base encibilikisiwe emoyeni, yathuthukiswa ngabakwa-Rolls Royce (1971) Ltd. ukuze inikeze impahla yeshidi engenziwa kalula futhi izonikeza ukudumba okuthuthukisiwe kuma-welded assemblies ukuze kuthathelwe indawo i-NIMONIC alloy 80A. ukuhlangabezana nenqubo ethile yokuklama mayelana nengcindezi yobufakazi namandla okukhasa.Manje isitholakala ngazo zonke izinhlobo ezijwayelekile.Izindlela zokushisela zale alloy ziyefana nalezo ezisetshenziswa okuvamile kwamanye ama-alloys ayisisekelo e-nickel aqinile.uring salvage welding operations, i-pre weld heat-treatment ayidingekile emibuthanweni eqinile yobudala kodwa ukwelashwa okulandelayo kokuqina kweminyaka kuyafiseleka ngemva kokuqedwa kokushisela kwe-salvage.Izinto ezibonakalayo zizoguga enkonzweni uma izinga lokushisa lingaphezu kuka-750 degree.
