Thaum vuamS3555j2wp huab cua dav hlau, Cov Ntawv Pom Zoo Vuam (Electrodes) yuav tsum phim nws corrosion-resistant thiab cov khoom siv tshuab. Ntawm no yog phau ntawv qhia ncaj qha:
Pom Zoo Vuam Hluav Taws Xob
Rau smaw (daim thaiv hlau tiv thaiv hlau arc vuam):
E7018-W2 (e.g., Aws A5.1 / A5.5):
MuajCU, CR, NITxhawm rau kom phim cov huab cua sib xyaw ua ke hlau lub npe sib xyaw.
Muab cov khoom siv zoo thiab tawg tsis kam.
Tshwj xeeb huab cua hluav taws xob:
Böhler Fox EV 65(1.5% ni, 0.3% Cu) lossisLincoln Conarc 70C1n.
Rau GMAW (MIG / Mag Vuam):
ER70s-6(AWS A5.18) nrogAR + COOP sib tov(rau kev siv dav dav).
Huab Cua Tshwj Xeeb:
G 89 hli hli1.5crmo (e.g., Oerlikon oPra 6 w).
Rau FCAW (Flux-cored arc vuam):
E71T-1C(AWS A5.20) nrogCu / ni Additives (e.g., Hobart Fabo 71W).
Cov kev txiav txim siab tseem ceeb
Preheating: 100–150°C (for thicknesses >15 hli kom tsis txhob muaj hydrogen cracking).
Tom qab Weld Tu: Tshem tawm slag kom ntseeg tau tias Patina tsim.
Sib Xws Twina: Siv cov electrodes nrogCU / CRTxhawm rau kom muaj kev sib dhos xeb.
