Nickel thiab Nickel Alloy Vuam Electrode
Ni 202
GB/T ENi4060
AWS A5.11 ENiCu-7
Nqe lus piav qhia: Ni202 yog Ni70Cu30 Monel alloy electrode nrog titanium calcium txheej.Nws tuaj yeem siv rau AC thiab DC.Cov hlau tso tawm muaj qhov ua kom tawg zoo vim yog cov ntsiab lus tsim nyog ntawm manganese thiab niobium.Nws muaj qhov zoo tshaj plaws vuam kev ua tau zoo nrog ruaj khov arc combustion, tsawg spatter, yooj yim tshem tawm slag, thiab zoo nkauj weld.
Daim ntawv thov: Nws yog siv rau kev vuam ntawm nickel-tooj liab alloy thiab cov hlau tsis sib xws, thiab tuaj yeem siv los ua cov khoom siv hloov pauv hloov pauv.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
C | Mn | Fe | Si | Nb | Al | Ti | Cu | Ni | S | P |
≤ 0.15 | ≤4.0 | ≤ 2.5 | ≤1.5 | ≤ 2.5 | ≤1.0 | ≤1.0 | 27.0-34.0 Nws | ≥62.0 | ≤ 0.015 | ≤ 0.020 |
Mechanical zog ntawm weld hlau:
Cov khoom kuaj | Tensile zog Mpa | Yield zog Mpa | Elongation % |
lav | ≥480 | ≥200 | ≥ 27 |
Pom zoo tam sim no:
Qws txoj kab uas hla (mm) | 2.5 | 3.2 | 4.0 |
Vuam tam sim no (A) | 50 ~ 80 | 90 ~ 110 ib | 110 ~ 150 ib |
Daim ntawv ceeb toom:
1. Cov electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 250 ℃ ua ntej vuam ua haujlwm;
2. Nws yog ib qho tseem ceeb los ntxuav cov xeb, roj, dej, thiab impurities ntawm vuam qhov chaw ua ntej vuam.
