Nyob rau hauv Asmeskas cov ntaub ntawv vuam (AWS) kev faib tawm rau vuam hluav taws xob, cov alphanumeric cov lej muab cov ntaub ntawv tseem ceeb hais txog pas nrig kev ua tau zoo, muaj pes tsawg leeg, thiab siv tau. Rau qhov dav siv davE7018 electrode, tus lej uas nqa cov ntsiab lus, thiab tus lej thib peb"1"Qhia lub luag haujlwm tseem ceeb hauv kev txhais lus nws txoj kev vuam thiab cov yam ntxwv flux. Hauv qab no, peb txiav cim qhov tseem ceeb ntawm "1" hauv E7018 thiab nws cov tswv yim cuam tshuam rau cov welders.
Rhuav tshem E7018 kev faib tawm
AWS AWS A5.1 tus qauv muab cov ntsiab lus hauv qab no rau txhua ntu ntawm cov caiE7018:
E: Qhia txog electrode.
70: Qhia txog qhov tsawg kawg tensile lub zog ntawm weld hlau (70, {1}} psi lossis 483 mpa).
1: Txhais tau tias cov qauv vuam thiab cov hom glux.
8: Qhia txog Flux muaj pes tsawg leeg thiab hom tam sim no (hydrogen, hlau hmoov, ac / dc +).
Lub ntsiab lus ntawm tus lej thib peb ("1")
Tus lej thib peb nyob rau hauv AWS cov kev faib tawm ua ke ob yam tseem ceeb:
Vuam txoj haujlwm:
1: Qhia txog lub electrode yog haum rauTag nrho Vuam Txoj Haujlwm-flat, kab rov tav, ntsug, thiab ua haujlwm.
Flux hom thiab kev sib xyaw tam sim no:
Rau E7018, "1" signifies aTsawg-Hydrogen Paassium Flux Daim TxheejNrog ntxiv cov hmoov av ntxiv. Qhov no flux tso cai rau electrode los ua haujlwm ntawm ob qho tib siHloov pauv tam sim no (AC)thiabncaj qha rau electrode zoo (DCEp).
Vim li cas cov "1" teeb meem hauv E7018
Qhov "1 1" ua rau versatility thiab kev ntseeg tau hauv cov ntawv thov tseem ceeb:
Txhua txoj haujlwm vuam: Txawj ua kom cov txiv pob ua ke kom cov pob txha sib tsoo hauv cov txheej txheem ntsug lossis cov qauv siv nyiaj ntau rau cov qauv hlau, lub xov tooj, thiab cov roj av.
Tsawg-hydrogen flux: Txo kev nqus hydrogen nqus nyob rau hauv weld hlau, txo txoj kev pheej hmoo ntawm hydrogen-inducts cracking (hic) nyob rau hauv high-zog lossis tuab-seem hlau.
AC / DC + Sib Xws: Muab hloov hloov hauv cov fais fab xaiv, zoo tagnrho rau kev ua haujlwm uas AC transformers feem ntau siv.
Muab piv rau E7018 rau lwm cov hluav taws xob
E6010: Thib peb "" kuj txhais tau tias txhua qhov chaw vuam, tab sis flux yog cellulose-based (xav tau DC +).
E7016: Cov "1" zoo ib yam tso cai rau txhua txoj haujlwm vuam, tab sis cov flux tsis muaj cov hmoov av cia.
E7024: Tus "2" txwv nws rau tiaj thiab kab rov tav nrog cov hlau loj-tso tawm hlau Oxide Flux.
Cov tswv yim cuam tshuam rau welders
Cov qauv thiab cov cai ua haujlwm: E7018's "1" Kev faib tawm "ua rau nws ua raws li AWS D1.1 tsim vuam lis cai, yuav tsum tau ua choj, vaj tse, thiab cov hlab ntsha, thiab cov hlab ntsha, thiab cov hlab ntsha, thiab cov nkoj siab.
Kev kho kom tiav: Nws AC sib xyaw tau muaj txiaj ntsig nyob rau hauv cov chaw deb nrog tsawg zog cov peev txheej.
Txo cov tsis xws luag: Helogen cov khoom lag luam yog qhov tseem ceeb rau kev siv cov hlau hluav taws xob siab lossis cov pob qij txha txwv kom tawg.
Xaus: Tus "1" ua kom muaj kev lees paub thiab hloov tau
Qhov "1" hauv E7018 tsis yog ib tus lej-nws yog qhov lav ntawm versatility, lub zog, thiab kev ntseeg tau nyob rau hauv kev thov vuam ib puag ncig. Los ntawm kev nkag siab txog qhov kev faib tawm no, cov neeg muaj txiaj ntsig tuaj yeem ntseeg cov hluav taws xob uas ua tau raws li cov kev qhia tshwj xeeb, ua kom tiav cov pob qij txha thoob plaws txhua txoj haujlwm. Seb puas yog lub tsev skyscrapers lossis kho cov tshuab hnyav, "1" hauv E7018 underscores nws lub luag haujlwm yog lub pob zeb ua tau zoo tshaj plaws.
