Cov hlau nickel hlau vuam electrodessawv cev rau ib pawg tshwj xeeb ntawm cov hlau filler tsim los rau kev sib koom ua ke thiab kho cov khoom siv nyuaj, feem ntau yog hlau cam khwb cia. AWS A5.15 ENi-C1 kev faib tawm, piv txwv los ntawm cov khoom Z208, txhais ib hom tshwj xeeb ntawm cov electrodes no. Cov chav kawm tshwj xeeb no ntawm cov hlau nickel alloy welding electrodes muaj lub hauv paus ntawm cov hlau qis-carbon thiab ib txheej nplua nuj hauv graphite, ua rau lawv siv tau nrog ob qho tib si AC thiab DC fais fab rau kev ywj pheej hauv ntau qhov chaw ua haujlwm.
Lub hauv paus ntsiab lus ua haujlwm ntawm hom nickel alloy welding electrodes no yog nyob ntawm kev hloov cov khoom sib xyaw rau hauv cov hlau vuam. Cov graphite ntau hauv cov txheej txheem txhawb nqa kev tsim cov qauv carbon-saturated. Thaum lub vuam raug tswj hwm, qeeb qeeb txias, cov nyiaj tso tawm khov kho ua cov hlau grey cast iron microstructure. Qhov no muab kev sib phim zoo rau cov khoom siv hauv paus uas tau kho, uas yog qhov tseem ceeb rau kev sib xws.
Ib qho tseem ceeb ntawm cov yam ntxwv ntawm cov nocov hlau nickel hlau vuam electrodesyog qhov tsis kam tawg ntawm cov hlau vuam. Cov khoom tso, thaum phim cov hlau grey hauv cov qauv, tau txais nws qhov brittleness thiab ductility tsawg. Qhov no ua rau thaj chaw vuam yooj yim rau kev tawg los ntawm kev ntxhov siab thermal tshwm sim thaum lub sijhawm txias. Yog li ntawd, kev siv kom zoo yuav tsum tau ua raws li kev ua ntej cua sov rau cov khoom siv hlau cam khwb cia thiab siv qeeb heev, tswj kev txias tom qab vuam kom txo qis thermal gradients thiab kev ntxhov siab.
Daim ntawv thov tseem ceeb rau ENi-C1 classified electrodes yog kev kho cov qhov tsis zoo hauv cov hlau grey cast castings. Qhov no suav nrog kev kho cov qhov tsis zoo, cov qhov me me, cov qhov xuab zeb, thiab cov kab nrib pleb uas los ntawm cov txheej txheem tsim khoom lossis tshwm sim thaum lub sijhawm ua haujlwm. Lawv siv feem ntau yog tsom mus rau kev kho dua qhov geometry thiab kev ua haujlwm ntawm cov khoom uas tsis raug rau cov khoom thauj siab lossis kev cuam tshuam.
Cov lus qhia tshwj xeeb ENi-C1 qhia txog ib pawg tshwj xeeb ntawmcov hlau nickel hlau vuam electrodestsim los rau kev rov ua dua hlau cam khwb cia. Lawv qhov txiaj ntsig yog nyob rau hauv kev tsim cov hlau sib xws, tab sis qhov no tau sib npaug los ntawm qhov yuav tsum tau ua kom zoo rau kev tswj hwm cua sov thaum lub sijhawm vuam kom tiv thaiv lawv qhov kev txwv ntawm kev tiv thaiv kab nrib pleb tsis zoo.
