** 1. Yog 1018 tib yam li A36? **
Tsis yog, 1018 thiab A36 tsis zoo ib yam. Lawv sib txawv ntawm cov hlau uas muaj cov ntsiab lus tseem ceeb {}} yog cov khoom siv roj carbon ntau dua thiab tso cai rau nws kom ua kom sov ntxiv. A36 yog qhov me me, qis}}} Tus qauv hlau, muaj txiaj ntsig zoo rau nws lub zog zoo thiab kev siv nyob rau hauv cov ntawv thov kev lag luam zoo li vaj tse thiab choj. Lub ntsiab sib txawv yog tias A36 muaj qhov tau hais tseg yam tsawg kawg zog lub zog, thaum 1018 muaj cov tshuaj lom neeg muaj pes tsawg leeg.
** 2. Dab tsi yog ER70s-2? **
ER70s {- 2 yog ib qho kev faib tawm rau cov roj carbon hlau vuam (GMAW lossis MTAWT ARGT (GTAWW lossis Tig Vuam). Nws yog ib qho xua hlau vuam vim nws muaj deoxidizers xws li silicon, manganese, thiab tseem zirconium thiab qee zaum txhuas). Cov deoxidizers ntxiv cia rau nws mus weld ntawm cov hlau uas muaj tus nqi me me, ua rau nws muaj kev tsis txaus siab thiab ua kom muaj cov khoom zoo nrog cov khoom lag luam zoo.
** 3. Dab tsi yog E7018 sawv rau? **
E7018 yog kev faib tawm electrode rau qhov tsawg {1} hydrogen, hlau hmoov electrode hlau vuam (smaw los yog pas nrig lossis lo vuam). Cov "e" sawv rau electrode. Tus "70" qhia tau lub zog tensile ntawm 70,000 phaus ib square nti (PSI). Qhov "1" txhais tau tias nws tuaj yeem siv rau hauv txhua qhov chaw vuam (tiaj tus, kab rov tav, ntsug, thiab overhead). Qhov "8" hais qhia txog hom kev sib txuas flux thiab qhov tam sim no nws siv; Ib qho "8" txhais tau qhov tsawg- hydrogen poov tshuaj flux flux thiab tias nws tuaj yeem siv nrog ob qho tib si AC (hloov pauv tam sim no) thiab DCEP (ncaj qha electrode zoo).
** 4. Dab tsi yog S sawv rau hauv ER70s? **
Qhov "S" hauv ER70s sawv rau "khoom" hlau. Qhov no txhais tau tias Vuam hlau yog tus tswj kav hlau ruaj khov, raws li txwv tsis pub "cored" xaim thiab muaj hmoov hlau thiab hlau.
** 5. Dab tsi yog qhov sib txawv ntawm ER70s-2 thiab ER70S-3? **
Qhov sib txawv thawj ntawm ER70s- 2 thiab ET70s-3 lus dag nyob rau hauv lawv cov tshuaj lom neeg muaj pes tsawg leeg, tshwj xeeb hom thiab tus nqi ntawm deoxidizers ntxiv. Er70s-2 muaj cov qib siab dua ntawm deoxidizers, suav nrog triple deoxidizers zoo li zirconium, thiab qee zaum txhuas, ntxiv rau silicon thiab manganese. Qhov no ua rau nws zoo heev rau vuam ntawm cov hlau nrog xeb, teev, lossis lwm yam paug. Er70s-3 muaj cov yooj yim muaj pes tsawg, feem ntau siv silicon thiab manganese li deoxidizers. Nws yog tsim los rau vuam muag ntawm huv, tshiab hlau thiab yog qhov feem ntau cov dav hlau-lub hom phiaj Mig xaim, muab cov duab arc zoo nkauj thiab cov noob ntoo uas huv.
