ASTM A36 muaj npe nrov rau nws cov khoom siv zoo heev, uas yog ib qho ntawm cov laj thawj tseem ceeb rau nws txoj kev siv dav. Nws tuaj yeem welded siv tag nrho cov txheej txheem arc vuam (SMAW, GMAW, FCAW, SAW) yam tsis tas yuav tsum tau ua ntej - cua sov los yog tom qab - vuam cov cua sov, tshwj xeeb tshaj yog rau cov seem thinner. Nws cov ntsiab lus carbon tsawg (Carbon Equivalent, CE, yog tsawg) txo qhov kev pheej hmoo ntawm kev tsim nyuaj, nkig martensite nyob rau hauv tshav kub- cuam tshuam cheeb tsam (HAZ), uas tuaj yeem ua rau txias tawg.
Piv rau siab dua -Lub zog qis-Alloy (HSLA) Steels:Cov hlau zoo li ASTM A572 Gr. 50 muaj lub zog ntau dua tab sis feem ntau muaj cov pa roj carbon ntau thiab cov alloys, muab cov pa roj carbon ntau dua. Qhov no yuav tsum tau tswj cov txheej txheem vuam, ua ntej- cua sov, thiab qis hydrogen kev coj ua kom tsis txhob HAZ tawg.
Piv rau "Weathering" Steels (piv txwv li, A588):Cov hlau no muaj cov ntsiab lus alloying xws li chromium thiab tooj liab rau kev tiv thaiv corrosion, uas tuaj yeem ua rau lawv nyuaj me ntsis rau vuam dua li A36, qee zaum yuav tsum tau muab cov hlau tshwj xeeb.
Piv rau Cov Cuab Yeej Hlau lossis Siab -Carbon Steels:Cov no muaj qhov tsis zoo weldability vim muaj cov ntsiab lus carbon siab heev thiab yuav tsum tau ua cov txheej txheem tshwj xeeb.
In summary, A36 is considered one of the easiest steels to weld, making it ideal for general fabrication. However, for thick sections (>20mm), me me ua ntej- cua sov tuaj yeem raug pom zoo los xyuas kom muaj suab nrov.
