Cov Hlau Sib Txuas Qis
J557
GB/T E5515-G
AWS E8015-G
Kev piav qhia: J557 yog lub electrode hlau tsis muaj hlau sib xyaw nrog cov txheej hydrogen sodium tsawg. Siv DCEP (cov electrode tam sim no ncaj qha zoo), thiab tuaj yeem vuam tau rau txhua qhov chaw.
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) | |
| -20 ℃ | -30 ℃ | ||||
| Tau lees paub | ≥540 | ≥440 | ≥17 | — | ≥27 |
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:
| (hli) Txoj kab uas hla ntawm tus pas nrig | 2.5 | 3.2 | 4.0 | 5.0 |
| (Ib) Vuam Tam Sim No | 60 ~ 90 | 80 ~ 110 | 130 ~ 170 | 160 ~ 200 |
Daim Ntawv Ceeb Toom:
1. Lub electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 350 ℃ ua ntej welding 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 txoj kev vuam luv luv thaum vuam. Txoj kev vuam nqaim yog qhov tsim nyog.
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.
