E7018 vuam pas nrig
Piav qhia:
AWS E7018 Vuam rodisaironpowderlow hydrogentypecarbon steel vuam electrode.Nws tuaj yeem siv rau txhua txoj haujlwm vuam nrog zoo tshaj plaws: qhov chaw me me yooj yim, yooj yim tsis muaj zog, muaj qhov ua haujlwm siab, zoo nkauj thiab slag yooj yim rau tshem tawm, thiab lwm yam Theseamweldmetal qhia tau txaus siab rau yas, zoo heev tsis tshua muaj kev kub ceev thiab qhov siab tawg. kuj.BothACand DC tuaj yeem siv.
DAIM NTAWV THOV:
AWS E7018 vuam qws Suitablefor vuam qhov tseem ceeb nruab nrab carbon hlau thiab tsis tshua muaj lub zog hlau, xws li 16Mn steel, qhov chaw ofships tsim los ntawm AA, B, D, E qib steel aswellas partsofboilers, siab txog ntsha thiab kav dej.
XAIV:
a.Before welding, cov hlau tsis sib haum yuav tsum tau muab tshem tawm kom tsis txhob tuaj yeem, xws li xeb, roj, noo noo, thiab lwm yam.
b.Short arc thiab nqaim weld hlaws pom zoo nyob rau hauv kev siv hlau ua haujlwm.
