Vuam electrodes tuaj yeem txheeb xyuas los ntawm cov hauv qab no:
1. Xim Coding thiab Markings
- Ntau cov vuam electrodes muaj cov xim tshwj xeeb ntawm lawv cov txheej. Piv txwv li, qee cov electrodes tej zaum yuav muaj cov xim sib txawv ntawm ib qho kawg uas qhia txog ib hom lossis specification.
- Kuj tseem muaj cov cim ntawm lub electrode nws tus kheej. Cov cim no feem ntau suav nrog cov ntaub ntawv xws li hom electrode (xws li E6011, E7018), cov chaw tsim khoom cov cai, thiab qee zaum cov lus qhia tshwj xeeb rau ntau yam tam sim no thiab cov ntawv thov.
2. Cov ntaub ntawv ntim khoom
- Lub ntim ntawm vuam electrodes feem ntau muab cov ncauj lus kom ntxaws rau kev txheeb xyuas. Qhov no suav nrog hom electrode, qhov loj me, AWS kev faib tawm (American Welding Society), thiab cov lus piav qhia ntawm cov ntawv thov tsim nyog.
- Nrhiav cov ntawv sau rau ntawm lub thawv lossis pob khoom uas qhia meej cov ntsiab lus no.
3. Cov yam ntxwv ntawm lub cev
- Ntau hom vuam electrodes muaj qhov sib txawv ntawm lub cev. Piv txwv li:
- Qee cov electrodes muaj cov txheej tuab tuab, thaum lwm tus muaj nyias nyias. Lub thickness thiab kev ntxhib los mos ntawm txheej tuaj yeem muab qhov qhia txog lub hom phiaj ntawm electrode.
- Qhov ntev thiab txoj kab uas hla ntawm lub electrode kuj tseem tuaj yeem yog qhov tseeb. Qee hom electrodes muaj nyob rau hauv qhov ntau thiab tsawg rau kev ua haujlwm vuam.
4. Kev sab laj thiab cov ntaub ntawv siv
- Xa mus rau welding phau ntawv, catalogs, los yog cov kev pab hauv internet muab los ntawm electrode manufacturers. Cov peev txheej no tuaj yeem pab koj txheeb xyuas cov electrodes raws li lawv cov yam ntxwv thiab kev npaj siv.
- Tham nrog cov kws paub txog kev siv vuam lossis cov tshuab vuam uas paub txog ntau hom electrodes thiab tuaj yeem muab kev taw qhia txog kev txheeb xyuas.
5. Chemical Composition Analysis (rau kev txheeb xyuas qib siab)
- Qee qhov xwm txheej, tshwj xeeb tshaj yog nyob rau hauv kev lag luam lossis kev tshawb fawb, kev tshuaj xyuas cov tshuaj muaj pes tsawg leeg tuaj yeem ua kom paub tseeb tias qhov vuam electrode. Qhov no suav nrog cov txheej txheem xws li spectroscopy los txiav txim siab cov ntsiab lus tam sim no hauv electrode txheej thiab cov tub ntxhais hlau. Txawm li cas los xij, qhov no yog ib txoj hauv kev ntau dua thiab tshwj xeeb.
