Galvanized nplooj ntawv feem ntau siv nyob rau hauv ntau yam lag luam vim lawv cov khoom tiv thaiv corrosion. Vuam galvanized los xij tuaj yeem sib txawv me ntsis ntawm cov hlau tsis tu ncua vim muaj cov zinc txheej. Nyob rau hauv tsab xov xwm no, peb yuav tham txog yuav ua li cas weld galvanized nplooj ntawv siv ib tug nruab nrab zaus DC chaw welder.
1. Kev nyab xeeb ua ntej
Ua ntej peb dhia mus rau hauv cov txheej txheem vuam, nws yog ib qho tseem ceeb kom ntseeg tau tias koj muaj kev nyab xeeb:
- Hnav cov khoom tiv thaiv vuam uas tsim nyog, suav nrog lub kaus mom hlau vuam uas tsim nyog.
- Siv qhov chaw ua pa kom zoo lossis hnav lub tshuab ua pa yog tias ua haujlwm hauv qhov chaw kaw.
- Xyuas kom koj qhov chaw ua haujlwm tsis muaj teeb meem thiab tsis muaj cov khoom siv hluav taws xob nyob ze.
- Muaj ib lub tshuab tua hluav taws npaj rau hauv rooj plaub.
2. Kev teeb tsa khoom siv
Txhawm rau txuas cov ntawv galvanized zoo, koj yuav xav tau cov khoom siv hauv qab no:
- Nruab nrab zaus DC qhov chaw welder
- Galvanized ntawv
- Vuam electrodes haum rau cov khoom siv galvanized
- Vuam hnab looj tes
- tsom iav kev nyab xeeb
- Vuam kaus mom hlau
- Respirator (yog tias tsim nyog)
- Cov tshuaj tua hluav taws
3. Ntxuav cov ntawv Galvanized
Galvanized nplooj ntawv tej zaum yuav muaj ib txheej ntawm zinc oxide, uas tuaj yeem cuam tshuam cov txheej txheem vuam. Txhawm rau ntxuav cov nplooj ntawv:
- Siv cov txhuam hlau los yog cov ntawv xuab zeb tshem tawm cov av, xeb, lossis cov khib nyiab.
- Ua tib zoo saib xyuas thaj chaw uas koj npaj yuav ua qhov vuam.
4. Vuam txheej txheem
Ua raws li cov kauj ruam no los txuas cov ntawv galvanized:
- Kho lub vuam tshuab chaw raws li qhov tuab ntawm cov ntawv galvanized. Nrog rau lub tshuab phau ntawv qhia txog kev taw qhia.
- Muab cov nplooj ntawv los ua welded, kom ntseeg tau tias lawv raug sib raug zoo.
- Muab koj cov khoom siv vuam, nrog rau lub kaus mom hlau thiab hnab looj tes.
- Tuav cov vuam electrodes kom ruaj khov tiv thaiv cov nplooj ntawv ntawm qhov chaw vuam.
- Tshem tawm qhov vuam pedal los tsim qhov vuam. Qhov nruab nrab zaus DC qhov chaw vuam yuav siv qhov tseeb ntawm lub siab thiab hluav taws xob tam sim no los koom nrog cov ntawv txheeb.
- Tso lub pedal thaum lub vuam tiav. Lub vuam yuav tsum muaj zog thiab ruaj ntseg.
5. Tom qab vuam
Tom qab vuam, tshuaj xyuas qhov vuam ntawm qhov tsis xws luag lossis tsis sib xws. Yog tias xav tau, koj tuaj yeem ua qhov chaw welds ntxiv los txhawb kev sib koom tes.
6. Huv huv
Ntxuav thaj chaw ua haujlwm, tshem tawm cov khib nyiab lossis cov khoom seem. Khaws koj cov cuab yeej kom zoo.
Hauv kev xaus, vuam galvanized nplooj ntawv nrog lub nruab nrab zaus DC qhov chaw vuam yuav tsum tau ua tib zoo npaj thiab ua tib zoo saib xyuas kev nyab xeeb. Los ntawm kev ua raws li cov kauj ruam no thiab siv cov cuab yeej tsim nyog, koj tuaj yeem tsim cov welds muaj zog thiab txhim khu kev qha ntawm cov ntawv galvanized rau ntau yam kev siv. Nco ntsoov sab laj cov chaw tsim khoom cov lus qhia rau koj lub tshuab vuam tshwj xeeb thiab nrhiav kev cob qhia yog tias koj tshiab rau vuam lossis ua haujlwm nrog cov khoom siv galvanized.
