Resistance chaw vuam yog cov txheej txheem siv dav hauv ntau yam lag luam, suav nrog tsheb, tsim khoom, thiab kev tsim kho. Txoj kev no suav nrog kev koom nrog ob lossis ntau daim hlau ua ke los ntawm kev siv cua sov thiab siab los ntawm kev siv hluav taws xob tiv thaiv. Txawm li cas los xij, txhawm rau kom muaj kev nyab xeeb thiab ua tiav cov vuam zoo, cov neeg ua haujlwm yuav tsum ua raws li cov lus qhia tshwj xeeb thaum ua haujlwm ntawm qhov chaw vuam tshuab. Hauv tsab xov xwm no, peb yuav tshawb nrhiav cov ntsiab lus tseem ceeb rau kev nyab xeeb thiab ua haujlwm tau zoo.
1. Kev ceev faj txog kev nyab xeeb:
Kev nyab xeeb yuav tsum yog qhov tseem ceeb tshaj plaws thaum ua haujlwm txhua lub tshuab, thiab qhov chaw vuam tsis muaj qhov tshwj xeeb. Nov yog qee qhov kev tiv thaiv kev nyab xeeb kom ua raws li:
- Hnav PPE tsim nyog: Ib txwm hnav cov khoom tiv thaiv tus kheej tsim nyog, suav nrog tsom iav kev nyab xeeb, cov hnab looj tes vuam, thiab cov khaub ncaws tiv thaiv nplaim taws.
- Qhov cua: Xyuas kom meej tias qhov chaw ua haujlwm muaj qhov cua txaus kom tawg pa taws thiab tiv thaiv kom tsis txhob muaj cov pa phem.
- Hluav taws xob kev nyab xeeb: Tshawb xyuas lub tshuab hluav taws xob sib txuas thiab hauv av kom tsis txhob muaj hluav taws xob txaus ntshai.
- Kev nyab xeeb hluav taws: Muaj cov cuab yeej tua hluav taws uas muaj nyob rau thaum muaj xwm txheej ceev.
2. Kev tshuaj xyuas tshuab:
Ua ntej pib ua haujlwm vuam, tshuaj xyuas lub tshuab vuam kom zoo:
- Cov hluav taws xob: Xyuas kom meej tias cov electrodes huv si thiab ua kom zoo.
- Cables: Tshawb xyuas cov hlua txuas rau qhov pom ntawm hnav lossis puas.
- Siab: Xyuas kom tseeb tias cov kev ntsuas siab tsim nyog rau cov khoom siv welded.
- Txias System: Xyuas kom lub tshuab ua kom txias ua haujlwm kom tsis txhob muaj cua sov.
3. Kev npaj khoom siv:
Kev npaj cov khoom tsim nyog yog qhov tseem ceeb rau kev ua tiav qhov chaw vuam:
- Khoom Thickness: Xyuas kom meej tias cov ntaub ntawv yuav tsum tau welded muaj ib tug uniform thickness.
- Kev huv huv: Tshem tawm tej yam kab mob, xws li xeb, xim, lossis roj, los ntawm cov hlau nto.
4. Welding Parameters:
Xaiv qhov kev vuam tsis raug yog qhov tseem ceeb rau kev ua tiav cov welds muaj zog thiab zoo ib yam. Cov parameter no suav nrog:
- Vuam tam sim no: Kho qhov vuam tam sim no raws li cov khoom siv thiab tuab.
- Lub sijhawm vuam: Teem lub sijhawm vuam kom ua tiav qhov xav tau kev nkag mus thiab kev sib khi lub zog.
5. Kev siv vuam:
Cov txheej txheem vuam kuj tseem ua lub luag haujlwm tseem ceeb hauv qhov zoo ntawm vuam:
- Electrode Qhov Chaw: Muab cov electrodes kom raug kom ntseeg tau tias cov vuam nyob hauv qhov chaw xav tau.
- Vuam Sequence: Txiav txim seb qhov ua ntu zus uas yuav tsum tau ua kom muaj ntau yam welds kom txo qis kev sib txawv.
- Saib xyuas: Ua tib zoo saib xyuas cov txheej txheem vuam kom paub meej tias muaj qhov tsis zoo lossis qhov tsis sib xws.
6. Kev soj ntsuam tom qab Weld:
Tom qab ua tiav kev ua haujlwm vuam, tshuaj xyuas cov welds kom zoo:
- Kev tshuaj xyuas qhov muag: Tshawb xyuas cov welds rau tej yam tsis xws luag, xws li cov kab nrib pleb lossis tsis tiav fusion.
- Kev kuaj kev puas tsuaj: Ua kev ntsuam xyuas kev puas tsuaj, yog tias tsim nyog, txhawm rau txheeb xyuas lub zog ntawm cov welds.
Los ntawm kev ua raws li cov lus qhia no thiab ua raws li cov txheej txheem kev nyab xeeb, cov neeg ua haujlwm tuaj yeem ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm cov khoom siv vuam tshuab. Qhov no tsis tsuas yog tiv thaiv tus neeg teb xov tooj xwb tab sis kuj ua kom zoo thiab kev ntseeg siab ntawm cov khoom siv welded, ua rau kev ua tiav tag nrho ntawm cov txheej txheem tsim khoom.
