PIAV TXOG:
Cov Hlau Uas Muaj Cov Hlau Uas Muaj Cov Hlau Qis
PAWG:
AWS A5.23: ECM4 Submerged Arc Solid Wire yog ib qho hlau sib xyaw ua ke uas muaj cov hlau tsis sib xyaw ua ke rau kev vuam hauv qab dej hauv cov ntawv thov muaj zog heev. AWS A5.23: ECM4 ua tau raws li AWS A5.23 chemistry M4, thiab yog tsim los rau cov qib tensile siab tshaj 110 ksi.
TSEEM CEEB DAIM NTAWV THOV:
Daim ntawv thov ib zaug thiab ntau daim ntawv thov nrog cov submerged arc flux pom zoo, High-Strength Low-Alloy steels, Quench & Tempered steels, Cov khoom siv hnyav, cov khoom siv qauv, lub nkoj hulls, cam khwb cia steels, boiler & pressure vessels
Cov hlau HSLA thiab Q&T
Kev tsim kho vaj tse
Kev tsim khoom ntawm jackup rig
Cov thav duab khoom siv hnyav
Cov nqaj hlau crane
NTA:
Cov hlau-cored hlau tuaj yeem muab cov nqi tso tawm zoo dua piv rau cov hlau khov kho ntawm cov amperages sib piv
Cov xov hlau uas muaj cored muab cov profiles nkag mus dav dua piv rau cov xov hlau khov kho ntawm cov kev sib piv vuam.
Muaj zog heev nrog kev ua kom sov qis zoo heev hauv qhov xwm txheej raws li-welded
Cov kev xav tau ntawm cov tshuaj lom neeg ntawm cov khoom siv vuam yog zoo ib yam li cov ntawm EM4 cov xov hlau khov kho
