Resistance spot welding yog ib txoj hauv kev siv los koom nrog cov khoom siv hlau hauv ntau qhov kev lag luam. Txawm li cas los xij, ib qho teeb meem tshwm sim thaum lub sijhawm txheej txheem no yog tsim cov welding pits lossis craters ntawm qhov chaw welded. Cov pits no tsis tsuas yog cuam tshuam cov txheej txheem kev ncaj ncees ntawm cov weld tab sis kuj cuam tshuam rau nws cov tsos. Hauv tsab xov xwm no, peb yuav tshawb txog qee cov tswv yim los txo qis qhov vuam hauv qhov chaw vuam tshuab.
- Optimal Vuam Parameters:Kev kho kom zoo ntawm vuam tsis yog qhov tseem ceeb heev kom txo qis qhov vuam vuam. Cov tsis muaj xws li vuam tam sim no, vuam lub sij hawm, thiab electrode quab yuam. Txhawm rau tiv thaiv kom tsis txhob muaj cua sov ntau thiab tshem tawm cov khoom, nws yog ib qho tseem ceeb kom nrhiav tau qhov sib npaug.
- Electrode Maintenance:Tsis tu ncua tshuaj xyuas thiab tswj cov vuam electrodes. Kev puas tsuaj los yog hnav-tawm electrodes tuaj yeem ua rau lub siab tsis sib xws, ua rau cov welding pits. Hloov lossis hloov kho electrodes raws li xav tau.
- Clean Workpiece Nto:Xyuas kom meej tias qhov chaw ua haujlwm yuav tsum tau welded yog huv si thiab tsis muaj kab mob, xws li roj, xeb, los yog xim. Qhov chaw qias neeg tuaj yeem cuam tshuam cov txheej txheem vuam thiab ua rau tsim cov pits.
- Clamping zoo:Ruaj ntseg clamp lub workpieces ua ke kom ntseeg tau tias txawm kev sib cuag ntawm electrodes thiab hlau. Cov clamping tsis zoo tuaj yeem ua rau cov welds tsis sib xws thiab tsim cov pits.
- Kev xaiv khoom siv:Xaiv cov khoom siv hluav taws xob zoo thiab cov khoom siv ua haujlwm rau cov ntawv thov tshwj xeeb. Qee qhov kev sib xyaw ua ke yog qhov yooj yim rau kev tsim lub qhov ntau dua li lwm tus, yog li xaiv cov ntaub ntawv uas sib xyaw ua ke zoo.
- Pulse Vuam:Xav txog kev siv cov txheej txheem pulse welding yog tias muaj nyob rau hauv koj qhov chaw vuam tshuab. Pulse welding tuaj yeem pab tswj cov khoom siv hluav taws xob thiab txo qhov muaj feem cuam tshuam ntawm vuam qhov.
- Vuam Sequence:Kho qhov vuam kab ke yog ua tau. Hloov qhov kev txiav txim uas ua rau ntau qhov chaw welds tuaj yeem faib cov cua sov kom sib npaug, txo qhov muaj feem ntawm qhov tsim.
- Cua txias:Siv cov kev ua kom txias kom zoo los tswj cov cua txias ntawm thaj chaw weld. Kev ua kom txias qeeb thiab tswj tau tuaj yeem pab tiv thaiv kom tsis txhob muaj kev sib zog sai uas feem ntau ua rau lub qhov dej tsim.
- Kev Tswj Xyuas Zoo:Tsis tu ncua tshuaj xyuas cov welded Cheebtsam txhawm rau txheeb xyuas thiab daws txhua qhov pits tam sim ntawd. Kev tshawb pom ntxov tuaj yeem tiv thaiv qhov teeb meem los ntawm qhov tsis zoo thiab cuam tshuam tag nrho qhov zoo ntawm qhov vuam.
- Kev cob qhia thiab kev txawj ntse:Xyuas kom cov neeg ua haujlwm tau txais kev cob qhia txaus hauv kev siv lub tshuab ua haujlwm welding. Cov neeg ua haujlwm txawj ntse tau zoo dua los saib xyuas cov txheej txheem thiab hloov kho lub sijhawm kom tsis txhob muaj qhov tsis xws luag.
Hauv kev xaus, txo qhov vuam qhov hauv qhov chaw vuam yuav tsum muaj kev sib txuas ntawm cov khoom siv tu, kev ua kom zoo dua qub, thiab cov neeg ua haujlwm txawj. Los ntawm kev ua raws li cov lus qhia no, cov neeg tsim khoom tuaj yeem ua tiav cov khoom muaj zog, zoo nkauj dua welds, txhim kho tag nrho cov khoom zoo ntawm lawv cov khoom.
