Kev siv lub taub qab vuam tshuab yuav tsum tau ua tib zoo saib xyuas kev nyab xeeb thiab kev ua haujlwm kom ntseeg tau tias kev ua haujlwm zoo thiab vuam zoo. Kab lus no muab cov ntsiab lus ntawm kev ceev faj tseem ceeb uas cov kws ua lag luam thiab cov kws tshaj lij hauv kev lag luam vuam yuav tsum ua raws li thaum siv lub tshuab vuam taub qab. Cov kev ceev faj no ua rau muaj kev nyab xeeb ntawm cov neeg ua haujlwm, kev ncaj ncees ntawm cov welds, thiab tag nrho cov txiaj ntsig ntawm cov txheej txheem vuam.
- Kev cob qhia kom zoo thiab ntawv pov thawj: Ua ntej ua haujlwm lub taub qab vuam tshuab, xyuas kom cov neeg ua haujlwm tau txais kev cob qhia thiab ntawv pov thawj hauv cov txheej txheem vuam, tshuab ua haujlwm, thiab cov txheej txheem kev nyab xeeb.
- Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE): Ib txwm hnav cov khoom tiv thaiv tus kheej tsim nyog, suav nrog cov kaus mom hlau, hnab looj tes, tsom iav kev nyab xeeb, thiab cov khaub ncaws tiv thaiv nplaim taws los tiv thaiv cov phom sij xws li hluav taws xob, hluav taws xob UV, thiab cua sov.
- Ua kom qhov cua txaus: Ua haujlwm hauv qhov chaw uas muaj cua zoo lossis siv cov tshuab tso pa kom zoo thiab tshem tawm cov pa taws thiab cov pa hluav taws xob uas tsim los thaum vuam.
- Kev Tshuaj Xyuas thiab Kev Kho Tshuab: Tsis tu ncua tshuaj xyuas lub tshuab vuam rau txhua qhov cim ntawm kev hnav, kev puas tsuaj, lossis ua haujlwm tsis zoo. Ua cov haujlwm tu txhua hnub, xws li ntxuav, lubricating, thiab hloov cov khoom siv, kom lub tshuab ua haujlwm zoo.
- Kho qhov hluav taws xob thiab qhov chaw tam sim no: xyuas kom meej tias lub tshuab vuam qhov hluav taws xob thiab qhov chaw tam sim no phim cov kev xav tau ntawm cov txheej txheem vuam thiab cov khoom siv welded. Kev teeb tsa tsis raug tuaj yeem ua rau tsis zoo weld zoo thiab muaj peev xwm txaus ntshai.
- Electrode / Filler Material: Siv cov khoom siv hluav taws xob tsim nyog lossis cov khoom siv muab tub lim pom zoo rau daim ntawv thov vuam tshwj xeeb thiab cov khoom siv. Kev siv cov khoom siv tsis raug tuaj yeem ua rau lub zog vuam tsis txaus thiab kev ncaj ncees.
- Grounding: Ua kom zoo hauv av lub tshuab vuam thiab cov khoom ua haujlwm kom tsis txhob muaj hluav taws xob poob siab thiab ua kom muaj kev nyab xeeb ntawm kev siv vuam.
- Vuam Cheeb Tsam Kev Nyab Xeeb: Kos thiab ruaj ntseg qhov chaw vuam kom tiv thaiv kev nkag tsis tau. Khaws cov khoom siv hluav taws xob kom deb ntawm qhov chaw vuam kom txo tau qhov hluav taws kub.
- Vuam Sequence: Ua raws li cov kev pom zoo welding ib ntus, tshwj xeeb tshaj yog nyob rau hauv ntau qhov kev vuam, kom txo qis kev cuam tshuam thiab kev ntxhov siab nyob rau hauv qhov kawg weld.
- Cov Khoom Siv Thaum Muaj Xwm Ceev: Muaj cov hluav taws tua hluav taws thiab cov khoom siv pab thawj zaug uas muaj nyob rau hauv qhov chaw vuam los daws cov xwm txheej kub ntxhov.
- Tom qab Weld Cleaning: Tom qab vuam, ntxuav qhov chaw weld kom tshem tawm slag, spatter, thiab lwm yam khoom seem uas tuaj yeem cuam tshuam rau kev ncaj ncees ntawm qhov vuam.
- Kev saib xyuas thiab saib xyuas: Xyuas kom tus neeg ua haujlwm tsim nyog saib xyuas cov haujlwm vuam txhua lub sijhawm, saib xyuas cov txheej txheem rau txhua qhov tsis sib xws.
Hauv kev xaus, ua raws li kev ceev faj thaum siv lub tshuab vuam pob tw yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm, qhov zoo ntawm welds, thiab kev ua haujlwm ntawm cov txheej txheem vuam. Kev cob qhia kom raug, cov cuab yeej tiv thaiv tus kheej, ua kom muaj cua txaus, kev tu lub tshuab, kev teeb tsa kom raug, thiab kev ua raws li cov txheej txheem kev nyab xeeb tag nrho ua rau muaj kev nyab xeeb thiab ua tiav vuam. Los ntawm qhov tseem ceeb ntawm kev nyab xeeb thiab ua raws li cov kev coj ua zoo tshaj plaws, cov vuam vuam thiab cov kws tshaj lij tuaj yeem ua tiav cov vuam zoo tshaj plaws thaum txo qis kev pheej hmoo thiab kev phom sij hauv kev ua haujlwm vuam.
