Cov hlau ENiFe-Cl MIG sawv cev rau ib pawg tshwj xeeb ntawmcov hlau nickel hlau vuam electrodes, tsim tshwj xeeb rau kev koom ua ke cov hlau cam khwb cia. Raws li cov hlau khov kho, nws tau tsim los siv nrog cov txheej txheem vuam hlau Inert Gas (MIG), muab txoj hauv kev zoo thiab ua tau zoo rau kev kho thiab tsim cov hlau cam khwb cia. Cov khoom no ua piv txwv txog lub luag haujlwm tseem ceeb uas cov electrodes vuam hlau nickel alloy tshwj xeeb ua si hauv kev kov yeej cov teeb meem cuam tshuam nrog kev vuam hlau cam khwb cia, cov khoom siv paub txog nws qhov kev cuam tshuam rau kev tawg.
Qhov kev siv tseem ceeb ntawm cov electrodes vuam nickel alloy no yog vuam cov hlau grey cast thiab ductile iron. Cov khoom sib xyaw nickel-iron (NiFe) yog qhov tseem ceeb vim tias nws tso cai rau qhov coefficient ntawm thermal expansion ntawm weld kom zoo ib yam li cov hlau cam khwb cia. Qhov kev sib haum xeeb no txo qhov kev ntxhov siab ntawm kev vuam thiab zam cov teeb meem tawg uas feem ntau pom nrog cov hlau welding electrodes. Cov electrodes no yog qhov tseem ceeb rau kev saib xyuas, kho, thiab kev ua haujlwm ntawm ntau yam lag luam.
Cov khoom siv hlau ntawm cov hlau vuam uas cov electrodes no tso rau hauv yog qhov zoo tseem ceeb. Qhov vuam uas tshwm sim qhia txog lub zog zoo heev thiab, qhov tseem ceeb dua, muaj kev ywj pheej siab. Qhov kev ywj pheej no tso cai rau qhov vuam kom nqus tau cov kev ntxhov siab uas tsim los thaum lub sijhawm txias thiab ntsws ntawm cov hlau cam khwb cia, tiv thaiv kev tawg hauv cov hlau vuam lossis thaj chaw kub. Cov qauv ntawm cov electrodes no yog tsim los tsim cov vuam ntom ntom nrog qhov porosity qis heev, ua kom ntseeg tau tias muaj kev sib koom ua ke.
Kev ua haujlwm, kev siv cov hlau MIG nocov hlau nickel hlau vuam electrodesmuab cov txiaj ntsig sib txawv ntawm kev tsim khoom thiab yooj yim siv. Cov txheej txheem MIG tso cai rau kev pub hlau txuas ntxiv mus, ua rau muaj kev sib txuas ntev dua, tsis muaj kev cuam tshuam piv rau cov txheej txheem electrode stick. Qhov no tuaj yeem ua rau muaj kev nce ntxiv ntawm cov nqi tso tawm thiab txo cov sijhawm vuam tag nrho, uas yog qhov tseem ceeb tshwj xeeb hauv cov haujlwm kho loj lossis cov chaw tsim khoom.
Cov hlau ENiFe-Cl MIG yog ib qho kev daws teeb meem siab heev hauv tsev neeg ntawmcov hlau nickel hlau vuam electrodesNws cov qauv tshwj xeeb daws cov teeb meem tshwj xeeb ntawm kev vuam hlau cam khwb cia los ntawm kev txo cov kev pheej hmoo tawg los ntawm kev nthuav dav thermal sib xws thiab kev txhim kho ductility. Rau txhua daim ntawv thov uas xav tau kev txhim khu kev qha, zoo weld ntawm cam khwb cia lossis ductile hlau Cheebtsam, pawg no ntawm nickel alloy vuam electrodes muab kev xaiv txhim khu kev qha thiab kev siv tshuab zoo.
