◆ Electrodes yog kim, yog li ntawd, siv thiab haus txhua me ntsis ntawm lawv.
◆ Tsis txhob muab pov tseg STUB xaus ntau dua 40-50 mm ntev.
◆ Electrode txheej tuaj yeem khaws cov dej noo yog tias raug rau huab cua.
◆Khaws thiab khaws cov electrodes (cua nruj) hauv qhov chaw qhuav.
◆ Tshav kub cov dej noo cuam tshuam / nquag electrodes hauv lub qhov cub electrode ziab ntawm 110-150 ° C rau ib teev ua ntej siv.
Nco ntsoov lub Moisture Affected Electrode:
- muaj rusty stub kawg
- muaj cov hmoov dawb pom hauv txheej
- ua porous weld.
Electrode cia khoom:
Kev ua haujlwm ntawm cov electrode raug cuam tshuam yog tias lub hau npog ua ntub.
- Khaws cov electrodes hauv cov pob ntawv uas tsis tau qhib hauv khw muag khoom qhuav.
- Muab cov pob khoom tso rau ntawm duckboard lossis pallet, tsis ncaj qha rau hauv pem teb.
- Khaws cia kom huab cua tuaj yeem ncig thiab dhau ntawm pawg.
- Tsis txhob cia cov pob khoom sib cuag nrog cov phab ntsa lossis lwm qhov chaw ntub dej.
- Qhov kub ntawm lub khw yuav tsum yog li 5 ° C siab tshaj qhov kub ntawm qhov ntxoov ntxoo sab nraud kom tiv thaiv kom tsis txhob muaj dej noo.
- Cov huab cua dawb hauv lub khw yog qhov tseem ceeb xws li cua sov.Tsis txhob muaj qhov hloov pauv dav hauv khw muag khoom kub.
- Qhov twg electrodes tsis tuaj yeem khaws cia rau hauv qhov zoo tagnrho tso cov khoom nqus dej noo (xws li silica gel) hauv txhua lub thawv ntim khoom.
Qhuav Electrodes: Dej hauv electrode npog yog qhov muaj peev xwm ntawm hydrogen hauv cov hlau tso thiab yog li yuav ua rau.
- Porosity nyob rau hauv weld.
- Cracking nyob rau hauv weld.
Indications ntawm electrodes cuam tshuam los ntawm noo noo yog:
- Dawb txheej ntawm npog.
- o ntawm npog thaum vuam.
- Dis-integration ntawm npog thaum vuam.
- Ntau dhau spatter.
- Ntau dhau rusting ntawm cov tub ntxhais hlau.
Electrode cuam tshuam los ntawm noo noo tuaj yeem qhuav ua ntej siv los ntawm kev muab tso rau hauv qhov cub tswj kom qhuav li ib teev ntawm qhov kub ntawm 110-150 ° C.Qhov no yuav tsum tsis txhob ua yam tsis tau hais txog cov xwm txheej tau teev tseg los ntawm cov chaw tsim khoom.Nws yog ib qho tseem ceeb uas hydrogen tswj electrodes khaws cia rau hauv qhuav, cua sov txhua lub sijhawm.
Yog xav paub ntxiv, xa mus rau cov chaw tsim khoom cov lus qhia thiab ua raws li lawv.
