Resistance spot welding yog txheej txheem vuam ntau yam siv hauv ntau qhov kev lag luam los koom nrog cov khoom siv hlau zoo. Qhov zoo ntawm qhov chaw welds nyob ntawm ntau yam, thiab ib qho tseem ceeb tsis yog lub siab siv rau vuam electrodes. Nyob rau hauv tsab xov xwm no, peb yuav tshawb txog qhov tseem ceeb ntawm lub siab ntawm electrode kev ua tau zoo nyob rau hauv qhov chaw vuam tshuab.
1. Electrode Contact Area
Lub siab siv rau vuam electrodes ncaj qha cuam tshuam rau thaj tsam ntawm cov electrodes thiab cov khoom ua haujlwm. Qhov siab dua ua rau thaj tsam loj dua. Qhov chaw sib txuas ntxiv no ua kom yooj yim dua hluav taws xob conductivity, ua rau kev txhim kho weld zoo. Nws xyuas kom meej tias tam sim no ntws tusyees los ntawm workpiece, txhawb kev sib raug zoo thiab muaj zog fusion.
2. Thaum tshav kub kub
Lub siab ua lub luag haujlwm tseem ceeb hauv kev tswj cov cua sov uas tsim thaum lub sijhawm vuam txheej txheem. Thaum cov electrodes siv lub siab rau lub workpiece, qhov tsis kam ntawm lawv generates tshav kub. Qhov loj ntawm lub siab cuam tshuam rau lub tshav kub tsim tus nqi. Kev kub siab tuaj yeem tsim kom muaj cua sov ntau dua, uas yog qhov tseem ceeb rau kev ua tiav cov vuam vuam zoo hauv cov ntaub ntawv tuab lossis cov txheej txheem vuam nyuaj.
3. Khoom Deformation
Lub siab siv los ntawm cov electrodes tuaj yeem ua rau cov khoom deformation hauv lub workpiece. Qhov kev deformation no yog qhov tseem ceeb tshwj xeeb rau cov khoom siv nrog cov coatings los yog cov kab mob. Los ntawm kev tawm dag zog txaus, cov electrodes tuaj yeem tawg los ntawm cov khaubncaws sab nraud povtseg, ua kom muaj qhov huv thiab tsis muaj kab mob sib kis. Qhov no ua rau muaj zog thiab txhim khu kev qha welds.
4. Electrode Hnav
Thaum lub siab yog qhov tseem ceeb rau kev tsim cov welds zoo, nws tuaj yeem cuam tshuam rau electrode hnav. Kev siab dhau heev tuaj yeem ua rau kom ceev electrode hnav, txo lawv txoj sia. Kev sib npaug kom zoo yog qhov tsim nyog kom ua tau raws li qhov zoo sib xws thaum txo cov electrode hnav. Qee cov electrodes tau tsim los tiv thaiv kev kub ntxhov siab dua thiab tsim nyog rau cov ntawv thov tshwj xeeb.
5. Cov Txheej Txheem Tswjhwm Siab
Niaj hnub nimno kuj qhov chaw vuam tshuab feem ntau suav nrog kev tswj xyuas siab tshaj plaws. Cov tshuab no tso cai rau cov tswv lag luam kom tswj hwm thiab saib xyuas lub siab siv rau cov electrodes. Los ntawm kev tswj cov qib siab zoo thoob plaws hauv cov txheej txheem vuam, cov tshuab no ua rau muaj qhov zoo sib xws thiab ua kom ntev electrode lub neej.
6. Kev hloov siab
Hauv qee qhov kev siv vuam, kev hloov pauv ntawm qhov siab yuav tsum tau los daws cov teeb meem tshwj xeeb. Piv txwv li, thaum vuam cov ntaub ntawv sib txawv los yog cov khoom siv nrog cov thicknesses sib txawv, kev kho cov qib siab tuaj yeem pab ua tiav cov welds zoo ib yam. Kev hloov pauv siab kuj tuaj yeem siv los tswj cov khoom siv hluav taws xob thiab tiv thaiv kev cuam tshuam hauv qee yam kev siv.
7. Kev ruaj ntseg zoo
Kev tswj lub siab yog ib qho tseem ceeb ntawm kev ruaj ntseg zoo hauv qhov chaw vuam. Cov neeg tsim khoom yuav tsum tsim thiab tswj xyuas qhov chaw siab kom ua tau raws li cov qauv kev sib txuas thiab cov kev qhia tshwj xeeb. Kev tshuaj xyuas ib ntus thiab ntsuas qhov ntsuas qhov ntsuas siab yog qhov tseem ceeb los xyuas kom meej tias cov qib siab xav tau ua tiav tas li.
Hauv kev xaus, lub siab yog qhov tseem ceeb hauv qhov chaw vuam tshuab uas cuam tshuam rau electrode kev ua tau zoo thiab vuam zoo. Kev tswj xyuas kom zoo ua kom pom kev sib cuag electrode, tsim kom muaj cua sov zoo, cov khoom deformation, thiab txo qis electrode hnav. Advanced siab tswj tshuab ntxiv txhim kho qhov tseeb thiab sib xws ntawm qhov chaw vuam, ua rau lawv yog ib qho tseem ceeb ntawm cov cuab yeej vuam niaj hnub.
