Cov Hlau Sib Txuas Qis
J555G
GB/T E5510-G
AWS A5.5 E8010-G
Kev piav qhia: J555G yog lub electrode ntsug uas muaj cellulose sodium ntau. Siv DCEP (direct current electrode positive). Nws tsim nyog rau kev vuam ntsug ntawm txhua qhov chaw ntawm cov kab sib dhos ntawm qhov chaw kav dej. 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 girth ntawm ntau yam hlau alloy qis.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | S | P |
| ≤0.20 | ≥1.00 | ≤0.50 | ≤0.035 | ≤0.035 |
熔敷金属力学性能 Mechanical zog ntawm weld hlau:
| 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 |
Kev tshuaj xyuas X-ray: qib II
Pom zoo tam sim no:
| (hli) Txoj kab uas hla ntawm tus pas nrig | 2.5 | 3.2 | 4.0 | 5.0 |
| (Ib) Vuam Tam Sim No | 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 khoom ntawmvuam electrodes, cov pas nrig vuam, thiab cov khoom siv vuam rau ntau tshaj 20 xyoo.
Peb cov khoom tseem ceeb suav nrog cov hlau tsis xebvuam electrodes, cov hlau carbon vuam electrodes,cov hlau tsis tshua muaj hlau vuam electrodes, cov electrodes vuam surfacing, cov electrodes vuam nickel & cobalt alloy, cov hlau tsis muaj zog & cov hlau tsis tshua muaj zog vuam, cov hlau stainless hlau vuam, cov hlau flux cored uas tiv thaiv roj, cov hlau vuam txhuas, cov hlau vuam submerged arc. cov hlau, cov hlau vuam nickel & cobalt alloy, cov hlau vuam tooj dag, cov hlau vuam TIG & MIG, cov hlau tungsten, cov hlau carbon gouging, thiab lwm yam khoom siv vuam & cov khoom siv tau.
