Cov Hlau Carbon Vuam Electrode
J425G
GB/T E4310
AWS A5.1 E6010
Kev piav qhia: J425G yog lub electrode ntsug downward uas muaj cellulose sodium ntau. Siv DCEP (direct current electrode positive), uas tsim nyog rau txhua qhov chaw ntsug downward welding ntawm lub voj voog ntawm qhov chaw pipeline. Thaum vuam txheej hauv qab, nws tuaj yeem vuam rau ib sab thiab tsim rau ob sab, thiab qhov ceev vuam yog ceev.
Daim Ntawv Thov: Siv rau kev vuam ntawm ntau yam kav hlau carbon.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | S | P |
| ≤0.20 | 0.30 ~ 0.60 | ≤0.20 | ≤0.035 | ≤0.040 |
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 | ≥420 | ≥330 | 22 | ≥27 |
Kev tshuaj xyuas X-ray: qib II
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) | 40 ~ 70 | 70 ~ 110 | 110 ~ 160 | 160 ~ 190 |
Daim Ntawv Ceeb Toom:
1. Qhib lub thawv vuam ua ntej siv, thiab siv nws kom ntau li ntau tau tom qab qhib lub thawv;
2. Feem ntau, tsis tas yuav ziab nws dua ua ntej vuam, thiab nws tuaj yeem ziab ntawm 70 ~ 90 ° C rau 1 teev thaum nws ntub.
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.
