Cov Hlau Sib Txuas Qis
J556
GB/T E5516-G
AWS E8016-G
Kev piav qhia: J556 yog cov hlau electrode uas tsis muaj hlau ntau nrog cov txheej txheem hydrogen potassium tsawg. Ob qho tib si AC thiab DC tuaj yeem siv tau, thiab tuaj yeem vuam rau txhua qhov chaw. Kev ruaj khov ntawm AC vuam yog qis dua me ntsis ntawm kev vuam ncaj qha.
Daim Ntawv Thov: Siv rau kev vuam cov hlau carbon nruab nrab thiab cov qauv hlau tsis tshua muaj hlau xws li Q390.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | S | P |
| ≤0.12 | ≥1.00 | 0.30 ~ 0.70 | ≤0.035 | ≤0.035 |
Cov khoom siv kho tshuab ntawm cov hlau vuam:
| Khoom sim | Lub zog tensile Mpa | Lub zog tawm los Mpa | Kev ntev % | Tus nqi cuam tshuam (J) -30 ℃ |
| Tau lees paub | ≥540 | ≥440 | ≥17 | ≥27 |
| Tau kuaj xyuas | 550 ~ 620 | ≥450 | 22 ~ 32 | — |
Cov ntsiab lus hydrogen diffusion ntawm cov hlau tso: ≤6.0mL / 100g (txuj kev glycerin)
Kev tshuaj xyuas X-ray: Kuv qib
Pom zoo tam sim no:
| Txoj kab uas hla ntawm tus pas nrig （hli) | 2.5 | 3.2 | 4.0 | 5.0 |
| Vuam tam sim no （Ib) | 60 ~ 90 | 80 ~ 110 | 130 ~ 170 | 160 ~ 200 |
Daim Ntawv Ceeb Toom:
1. Lub electrode yuav tsum tau ci rau 1 teev ntawm 350 ℃ ua ntej vuam ua haujlwm;
2. Nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav cov xeb, roj nplai, dej, thiab cov khoom tsis huv ntawm cov khoom vuam ua ntej vuam;
3. Siv lub voj voog luv luv thaum vuam. Txoj kev vuam nqaim yog qhov tsim nyog;
4. Txuas lub electrode rau lub ncej zoo thaum ua haujlwm ntawm DC.
Wenzhou Tianyu Electronic Co., Ltd. tau tsim muaj xyoo 2000. Peb tau koom nrog kev tsim cov electrodes vuam, cov pas nrig vuam, thiab cov khoom siv vuam rau ntau tshaj 20 xyoo.
Peb cov khoom tseem ceeb suav nrog cov hlau tsis xeb vuam electrodes, carbon hlau vuam electrodes, qis alloy vuam electrodes, surfacing vuam electrodes, nickel & cobalt alloy vuam electrodes, mild steel & low alloy vuam wires, stainless hlau vuam wires, gas-shielded flux cored wires, txhuas vuam wires, submerged arc vuam. wires, nickel & cobalt alloy vuam wires, tooj dag vuam wires, TIG & MIG welding wires, tungsten electrodes, carbon gouging electrodes, thiab lwm yam khoom siv vuam & khoom siv tau.
