1. Haum rau STAINLESS STEEL THIAB CARBON STEEL LOS SIS LOW ALLOY steel DISsimilar STEEL welding, STAINLESS steel composite phaj cladding WELDING, 308 SERIES STAINLESS STEEL SURFACING Vuam ntawm carbon steel los yog tsawg alloy STEEL.
2. Tus qauv peb ntsib: GB/T983 E307-16, AWS A5.4 E307-16 & A5.4M E307-16, ISO3581-A:E(18 9 Mn Mo) R 1 2, ISO3581-B:ES307- 16
Daim ntawv thov: Siv rau tib hom STAINLESS steel qauv, cov hlau sib xyaw thiab cov hlau tsis sib xws hauv cov khoom siv hluavtaws, petrochemical thiab lwm yam khoom siv, kuj tuaj yeem siv rau nuclear reactor, siab hlab ntsha sab hauv phab ntsa hloov txheej txheej surfacing thiab ntauwd inner tivthaiv vuam.
Nta
1. Titanium calcium stainless hlau electrode, lub ntsiab muaj pes tsawg leeg yog 22% CR-12% Ni;
2. ruaj khov arc, zoo nkauj sib sau, zoo ripples, ob peb splashes, yooj yim de-slagging, zoo hluav taws tsis kam ntawm cov tshuaj ntawm daim tawv nqaij, zoo stomatal kuj.
3. Cov hlau weld muaj ntau ferrite thiab muaj qhov tsis tshua muaj tawg.
Titanium calcium hom ultra-low carbon Cr23Ni13 stainless hlau electrode, tuaj yeem siv rau ob qho tib si AC thiab DC, tsis muaj niobium, titanium thiab lwm yam khoom siv ruaj khov tuaj yeem tiv thaiv intercrystalline corrosion los ntawm carbide nag lossis daus. Siv hauv cov hlau tsis muaj steel, cov hlau sib xyaw thiab cov hlau tsis sib xws, xws li hluavtaws fiber ntau, petrochemical thiab lwm yam khoom siv.
Kev npaj ua ntej welding:
Cov electrode yuav tsum yog 300 ~ 350 ℃ rau 1 teev kom qhuav, lub sij hawm ntub dej hnyav los muab qhov kub kom qhuav rau 350 ℃ los yog tsim nyog ncua sij hawm kom qhuav, thiab ziab txheej txheej kom deb li deb tau tsis tshaj 3 txheej; Siv zog siv kom qhuav los yog muab tso rau hauv lub thoob hluav taws xob rwb thaiv tsev tsis pub ntau tshaj 2 hnub kom txuag tau, zam qhov tsis tsim nyog thib ob kom qhuav, txhawm rau tiv thaiv cov electrode txheej tawm.
