AWS A5.13 ENiCrFe-1 Nickel alloys Manual electrode Welding izesekeli
I-nickel-based alloy welding wire inokusebenza kahle kokumelana negesi esebenzayo, i-caustic medium, ukumelana nokugqwala ekunciphiseni i-asidi medium, futhi inamandla aphezulu, i-plasticity enhle, ukuguqulwa okubandayo nokushisayo kanye nezici zokucubungula kanye nokushisela, ngakho-ke, isetshenziswa kabanzi ku-petrochemical, insimbi, amandla e-athomu, ukuthuthukiswa zasolwandle, zezindiza, indiza kanye nezinye izimboni, ukuxazulula insimbi engagqwali jikelele kanye nezinye izinsimbi, izinto non-metallic abakwazi ukuxazulula inkinga ukugqwala ubunjiniyela, kuyinto ebaluleke kakhulu impahla metal ukugqwala. Ama-alloys asekelwe ku-nickel abhekisela kuma-alloys asekelwe ku-nickel futhi aqukethe izakhi ze-alloying futhi angamelana nokugqwala kweminye imidiya. Uma ihlukaniswa ngokwamakhemikhali ayo, ikakhulukazi ama-alloys e-nickel, nickel-copper, nickel-molybdenum (nickel-molybdenum ferrolybdenum) alloys, nickel-chromium (nickel-chromium-iron) alloys, nickel-chromium-molybdenum-cluchrominum nickin ( -ama-alloys e-molybdenum kanye nama-alloys e-nickel-chromium-molybdenum yethusi) kanye ne-nickel-iron chromium (zombili ama-alloys asekelwe ku-iron-nickel) nezinye izigaba. I-nickel welding wire ERNi-1 isetshenziselwa ukushisela i-200, i-201 ye-nickel alloy kanye ne-nickel-plated steel plate; ukushiselwa kwensimbi ne-nickel izinto ezingafani; Ukushisela okungaphezulu kwembondela yensimbi. I-Nickel-copper welding wire ERNiCu-7 Monel 400 ingxubevange ngokwayo i-welding; kanye nokushiselwa kwe-Monel 400 alloy ngensimbi; Isetshenziselwa ukuvela kwensimbi. I-Nichrome welding wire ERNiCrFe-3 isetshenziselwa ukushisela izinto ezihlukene zokushisela amajoyinti amelana ne-creep; - Ukushiselwa kwe-austenitic, izinsimbi ze-ferritic kanye nama-nickel alloys aphezulu, ukushiselwa kwezinsimbi ze-alloy eziqukethe i-9% ye-nickel ye-Nichrome welding wire ERNiCrFe-7 isetshenziselwa ama-alloys wokushisela kanye nokushisela insimbi engaphezulu, elungele ukwakhiwa kwama-reactors enyukliya. Ukushiselwa kwentambo yokushisela ye-nickel-chromium-molybdenum ERNiCrMo-3 INCONEL625, INCONEL825, INCONEL25-6Mo kanye ne-MONEL400 alloys; - Ukushisela phakathi kwe-ultra-high amandla ensimbi ye-austenitic kanye ne-INCOLOY020 alloy; Ukushisela phakathi kwama-alloys asekelwe ku-nickel kanye nensimbi engagqwali izinto ezingafani; Ukuqina kwensimbi
Isicelo & Okujwayelekile
Le ELECTRODE ESURFACING ESEKELWE ku-COBALT INGASETSHENZISWA EMHLABENI WE-LINING WE-SHAFT SLEEVE, UKUCIKA UCALA LOKUSEBENZA KWE-CHEMICAL FIBBER, SAWTOOTH, SCREW PUSH ROD, izinga lokushisa ELIPHEZULU kanye ne-High pressure valve kanye nepompo yokucindezela OKUPHEZULU NK. Ubukhulu obungaphezulu be-workpiece kufanele bube ngaphansi kuka-Ra12.5μm, futhi ukugqwala okungaphezulu, amafutha nokunye ukungcola kufanele kususwe ngokuqinile. I-matrix akufanele ibe nemifantu, ama-pores, isihlabathi nezinye iziphambeko, futhi imiphetho namakhona kufanele kube yindilinga. Ngaphambi kokuvela phezulu, amazinga okushisa ahlukene kufanele akhethwe ngokusho kwe-substrate material for preheating. Uma okubalulekile kwe-matrix kuyinsimbi ekwazi ukumelana nokushisa noma i-martensitic insimbi engagqwali nezinye izinto ezisebenza kabi ngokushisela, ungqimba olungaphezulu lwensimbi engenasici ye-austenitic kufanele lushiselwe endaweni ye-matrix, bese ingxubevange esekwe ku-cobalt kufanele ivele ngaphezulu ngemva kokucubungula okubushelelezi thuthukisa ukumelana nokuqhekeka futhi ugweme imifantu. Noma ngabe i-AC noma i-DC arc welding power supply ingasetshenziselwa ama-electrode e-D802 kanye ne-D812. Kunconywa ukunikezwa kwamandla we-Dc arc welding.
Izici
I-GEH-SL12 titanium calcium coated cobalt-base electrode engaphezulu. I-Cobalt-cr-tungsten alloy isetshenziswa njengentambo eyinhloko. Kunconywa ukuxhumana kwe-Dc reverse. Insimbi engaphezulu ingagcina ukumelana nokugqokwa okuhle nokumelana nokugqwala ku-650 ℃. Ngaphambi kokushisela, kufanele kubhakwe ku-300-350 ℃ ihora elingu-1; Isendlalelo esiqinile endaweni yensimbi eyisisekelo kufanele sisuswe ukuze kugwenywe imifantu kanye nokonakala. Ngokusho kobukhulu bensimbi eyisisekelo kanye nohlobo lwensimbi eyisisekelo, kufanele ishiswe kuqala ku-300-600 ℃, futhi i-arc welding encane yamanje emfishane ifanelekile.
