Nickel thiabNickel Alloy Vuam Electrode
N307-4
GB/T ENi6093
AWS A5.11 ENiCrFe-4
Nqe lus piav qhia: Ni307-4 yog nickel-based electrode nrog qis-hydrogen sodium txheej.Siv DCEP (direct tam sim no electrodezoo).Nws muaj kev ua haujlwm zoo heev nrog kev 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-chromium-hlau alloys, xws li Ni600, Ni800/800H thiab zoo sib xws los yog npib tsib xee-raws li superalloys nrog ib tug ua hauj lwm kub ntawm 900 ° C. Nws kuj yuav siv tau rau low-temperature steels uas muaj Ni3% ~ 9%, xws li ASTM A333, A334, A353, A522, Lub vuam ntawm A553 kuj tseem siv tau rau cov hlau sib txawv ntawm Mo400, Ni825, stainless hlau thiab cov hlau tsis tshua muaj hlau.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| C | Mn | Fe | Si | Ni | Cr | Mo | Nb + Ta | S | P |
| ≤ 0.20 | 1.0 ~ 5.0 | ≤ 12.0 | ≤1.0 | ≥60.0 | 13.0-17.0 Nws | 1.0 ~ 3.5 hli | 1.0 ~ 3.5 hli | ≤ 0.015 | ≤ 0.020 |
Mechanical zog ntawm weld hlau:
| Cov khoom kuaj | Tensile zog Mpa | Yield zog Mpa | Elongation % |
| lav | ≥650 | ≥360 | ≥18 |
Pom zoo tam sim no:
| Qws txoj kab uas hla (mm) | 2.5 | 3.2 | 4.0 |
| Vuam tam sim no (A) | 60 ~ 90 | 80 ~ 110 ib | 110 ~ 150 ib |
Daim ntawv ceeb toom:
1. Cov electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 300 ℃ 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.Sim siv luv luv arc rau vuam.
