ER70S2 yog tus hwm MIG & TiG hlau rau vuam ntawm txhua qib ntawm cov hlau me me thiab cov pa roj carbon steel, ua cov vuam zoo nrog qhov porosity tsawg.Nws yog ib tug triple deoxidized hlau (Zirconium, Titanium, thiab Aluminium) ua rau nws xaiv zoo heev rau vuam tshaj xeb thiab zeb nplai.Tsis muaj flux yuav tsum tau nrog cov khoom no.
TSEEM CEEB:
cov kav dej thiab offshore drilling rigs, cov qauv steel ua haujlwm
