LubE71T-1C/1M-PLUS A5.20 sawv cev rau kev nce qib tseem ceeb hauv kev siv tshuab vuam hlau tsis muaj roj (FCAW). Tsim los rau kev siv tau ntau yam thiab kev ntseeg siab, cov hlau carbon electrode no muab kev ua haujlwm zoo tas li yam tsis tas yuav muaj roj tiv thaiv sab nraud. Zoo tagnrho rau kev siv sab hauv tsev thiab sab nraum zoov, E71T-1C hlau ua rau kev vuam yooj yim thaum txo cov nqi khoom siv thiab kev teeb tsa nyuaj, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tsim kho, kho, thiab tsim khoom.
Tau ntawv pov thawj raws li AWS A5.20 tus qauv, lub E71T-1C electrode zoo heev hauv kev vuam cov hlau carbon nyias-gauge xws li 22-gauge daim hlau hlau txog li 3/16-nti (4.8 hli) tuab. Nws cov qauv flux tshwj xeeb tsim cov txheej slag tiv thaiv uas tiv thaiv lub pas dej vuam molten los ntawm kev ua qias tuaj hauv huab cua. Qhov kev tsim no ua kom ntseeg tau tias cov hlaws dai zoo nkauj, tsawg kawg nkaus spatter, thiab yooj yim tshem tawm slag. Cov hlau'Qhov sib xws nrog cov khoom siv vuam MIG txheem ntxiv ua rau nws nkag mus tau yooj yim thoob plaws cov chaw ua haujlwm thiab cov chaw ua haujlwm.
Ib qho tseem ceeb ntawm qhov zoo ntawmE71T-1C/1M-PLUS A5.20 muaj nws qhov kev ywj pheej ua haujlwm. Tsis zoo li cov xov hlau uas tiv thaiv roj, cov electrode tiv thaiv tus kheej no ua haujlwm tau zoo hauv cov huab cua sab nraum zoov lossis qhov chaw tsis muaj cua uas cov roj tawg ua rau kev vuam tsis zoo. Nws cov yam ntxwv nkag mus tob ua rau muaj kev sib xyaw ua ke ntawm cov pob qij txha, cov fillets, thiab cov butt welds.—tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau kev kho tsheb, kev tsim nkoj, thiab kev sib dhos hlau. Cov hlau's tus cwj pwm arc ruaj khov pab txhawb kev vuam ntsug-down, txhawb kev tsim khoom ntawm cov haujlwm ceev ceev.
Kev ruaj ntseg zoo yog qhov tseem ceeb rau E71T-1C xaim's tsim. Cov qauv ferrite tswj hwm hauv cov hlau vuam xa cov zog tensile ua tau raws li 70 ksi (480 MPa) qhov yuav tsum tau ua tsawg kawg nkaus, nrog rau kev tiv thaiv tawg zoo heev thiab ductility. Rutile-based slag Cheebtsam ua kom zoo dua qhov kev ua haujlwm ntub rau cov qauv hlaws dai sib xws thaum txo qis kev pheej hmoo ntawm cov ntaub ntawv nyias. Qhov sib npaug ntawm lub zog thiab kev ua haujlwm ua kom ntseeg tau tias ua raws li cov qauv kev lag luam tseem ceeb rau cov khoom thauj khoom.
Rau cov neeg tsim khoom uas muab qhov tseem ceeb rau kev ua haujlwm zoo thiab kev siv nyiaj tsim nyog, qhovE71T-1C/1M-PLUS A5.20 muaj cov txiaj ntsig pom tseeb. Kev tshem tawm cov thoob roj txo cov nra hnyav thiab cov nuj nqis siv los ntawm 15–25%. Nws qhov kev tso dej siab thiab qhov tsawg kawg nkaus tom qab vuam ua rau lub sijhawm ua haujlwm luv luv, thaum kev pub mov tas li txo cov xov hlau jams hauv kev teeb tsa tsis siv neeg. Raws li kev lag luam nrhiav kev daws teeb meem vuam yooj yim, pheej yig, E71T-1C ua kom nws lub luag haujlwm ua lub cuab yeej tseem ceeb rau kev koom ua ke ntawm cov hlau carbon thoob plaws kev tsim kho, kev saib xyuas, thiab kev tsim khoom lag luam.
