Lub ER70S-2 yog qhov zoo tshaj plawsArc Vuam Hlautsim los rau Gas Metal Arc Vuam (GMAW/MIG) thiab Gas Tungsten Arc Vuam (GTAW/TIG) cov txheej txheem. Ua ib qho hlau carbon-coated tooj liab, nws feem ntau yog siv rau kev koom ua ke txhua qib ntawm cov hlau qis-carbon. Nws cov qauv yog tsim los tsim cov vuam siab-kev ncaj ncees uas muaj qhov porosity tsawg thiab zoo li hlaws dai. Cov Hlau Arc Vuam Tshwj Xeeb no yog qhov tseem ceeb siv tau hauv kev tsim khoom, kho, thiab kev tsim khoom uas qhov vuam txhim khu kev qha thiab huv si yog qhov tseem ceeb.
Qhov kev ua tau zoo tshaj plaws ntawm cov hlau vuam no yog vim nws cov tshuaj lom neeg tshwj xeeb. Kev faib tawm ER70S-2 suav nrog cov ntsiab lus deoxidizing ntxiv—xws li silicon, manganese, thiab ib feem me me ntawm txhuas, zirconium, thiab titanium—dhau ntawm tus qauv ER70S-6 formulation. Lub kaw lus deoxidizing robust no ua rau nws zoo heev ntawm kev them nyiaj rau cov khoom tsis huv ntawm cov hlau puag, xeb lossis zeb nplai. Qhov noArc Vuam Hlaunws tsim nyog heev rau kev vuam rau ntawm cov chaw uas tsis huv zoo lossis thaum muaj xwm txheej uas tsis yooj yim ntxuav ua ntej.
Cov yam ntxwv ua haujlwm ntawm cov hlau ER70S-2 muaj xws li kev hloov pauv arc du thiab ruaj khov, uas ua rau yooj yim siv rau cov neeg vuam ntawm ntau qib kev txawj. Cov hlau pub tsis tu ncua, txo qhov spatter thiab txo lub sijhawm ntxuav tom qab vuam. Cov khoom siv vuam ua rau pom cov khoom siv kho tshuab zoo dua, suav nrog lub zog tensile zoo thiab ductility, ua tau raws li qhov yuav tsum tau ua ntawm AWS A5.18 tus qauv. Cov hlau vuam kuj qhia tau tias muaj kev tiv thaiv zoo rau kev tawg solidification, txhim kho qhov ruaj khov thiab kev nyab xeeb ntawm cov qauv vuam.
Hom hlau no siv tau dav hauv ntau qhov chaw. Nws feem ntau siv rau hauv kev tsim cov thav duab hlau, kev tsim cov khoom siv hauv tsheb, kev tsim nkoj, thiab kev tsim khoom lag luam dav dav. Nws muaj ntau yam thiab zam txim rau qhov chaw uas muaj cov av qias me ntsis ua rau nws yog qhov kev xaiv zoo rau kev vuam hauv chaw ua haujlwm thiab kev vuam hauv tsev, ua kom muaj zog thiab txhim khu kev qha hauv cov hlau carbon tseem ceeb.
Lub ER70S-2 sawv cev rau qib siab tshaj plawsArc Vuam Hlaukev daws teeb meem rau cov ntawv thov carbon steel. Nws cov tshuaj lom neeg deoxidizing siab heev, ua ke nrog kev ua haujlwm vuam yooj yim rau tus neeg siv thiab cov txiaj ntsig txhim khu kev qha, tsim nws ua qhov tseem ceeb rau kev ua tiav cov vuam zoo, ruaj khov. Rau cov haujlwm xav tau kev sib xws thiab lub zog hauv kev koom nrog cov hlau carbon qis, cov hlau no muab cov kev xaiv zoo thiab ntseeg tau dav.
