I-AWS A5.13 ECoCr-A Inhlanganisela yokwenziwa kwe-weld ye-electrode ebheke kanzima
I-GEH-SL6 iyi-electrode engaphezulu esekwe ku-cobalt ngokuhambisana ne-AWS A5.13 ECOCRA-A ejwayelekile. Isetshenziselwa kakhulu ukubeka izinga lokushisa eliphezulu namavalvu omfutho ophezulu, ama-shear blades ashisayo, ama-valve enjini, ama-turbine blades, njll. Ingasetshenziselwa kokubili i-AC ne-DC. Kunconywa ukusebenzisa uxhumano lwe-DC reverse kanye nokuxhumeka kwe-electrode positive. I-arc ezinzile, ukumbozwa kahle kwe-slag, umumo omuhle. Isendlalelo esingaphezulu sinezinto ezinhle kakhulu ezibanzi zemishini ebangeni lokushisa eliphakeme elingaphansi kuka-800 ℃, futhi linokumelana nokugqwala okuhle, ukumelana ne-oxidation kanye nokumelana nokugqokwa kwe-intermetallic. Isendlalelo esingaphezulu singenziwa ngomshini.
Isicelo & Okujwayelekile
I-GEH-SL6 iwuhlobo lokushisela okungaphezulu kwe-valve yenjini, i-turbine blade, izinga lokushisa eliphezulu kanye ne-valve yomfutho ophezulu, i-hot forging die kanye nezinye izingxenye zokumelana nokushisa okuphezulu kanye nezingxenye zokumelana nokugqwala. Enqubweni yokushisela, ukuze kuhlanganiswe ngokuqinile ne-substrate, kuyadingeka ukuthululela ukungena okujulile. Ngakho-ke, indlela yokushisela i-arc emfushane kuphela ingamukelwa. Okwesibili, ukuze kuxazululwe inkinga ye-deep pool kanye ne-base material encibilika ngokweqile ngesikhathi sokushisela i-arc emfushane, izinga lokuhlanjululwa liphezulu. Ukuntuleka kwezingxenye ezisebenzayo kungqimba lwe-weld kunciphisa inkinga yokumelana nokugqoka. Kumele kusetshenziswe indlela yokuvela okuningi, okunezingqimba eziningi. Ngale ndlela, hhayi kuphela izingxenye ezisebenzayo nokumelana nokugqoka ku-backsurfacing layer ukwandisa ungqimba ngongqimba. Ngaphezu kwalokho, izendlalelo ezimbalwa zokuqala ezingaphezulu nazo zidlala indima yesendlalelo soguquko, zinciphisa ukuqhekeka okubangelwa umehluko we-coefficient yokwandisa okushisayo phakathi kwezingqimba ezimbili eziseduze. Phakathi naleso sikhathi, indlela yokunyakaza komugqa oqondile, indlela yokunyakaza kwesikali sezinhlanzi, indlela yokunyakaza kwe-herringbone noma indlela yokunyakaza kwe-arc agitation emfushane kufanele yamukelwe.
Izici
Lena i-titanium calcium coating cobalt base surfacing electrode, ifanele ukuxhunywa kwe-DC reverse, insimbi engaphezulu isengagcina ukumelana nokugqokwa okuhle nokumelana nokugqwala ku-650 ℃, ukumelana nomthelela kanye nokumelana nokukhathala okubandayo nokushisayo. Ingasetshenziswa ezidingweni ezingaba ngu-650 ℃ umsebenzi usengakwazi ukulondoloza ukumelana nokugqokwa okuhle nokumelana nokugqwala okuthile, kanye nomthelela nokubanda nokushisa endaweni enyakazayo, kungaba nokusebenza okuhle.
