Resistance welding yog ib txoj kev siv dav hauv ntau lub lag luam los koom nrog cov khoom siv hlau kom zoo thiab ruaj ntseg. Qhov zoo ntawm cov ntsiab lus weld tsim los ntawm cov tshuab vuam vuam yog qhov tseem ceeb tshaj plaws los xyuas kom meej qhov kev ncaj ncees thiab ua haujlwm ntev ntawm cov khoom kawg. Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv qhov tseem ceeb ntawm kev soj ntsuam weld point zoo nyob rau hauv kuj vuam tshuab.
1. Kev tshuaj xyuas qhov muag:
Kev kuaj pom pom yog thawj kauj ruam hauv kev ntsuas qhov zoo ntawm qhov chaw weld. Cov kws tshuaj ntsuam xyuas yuav tsum nrhiav ntau yam kev pom, xws li cov tsos ntawm cov weld nugget, lub xub ntiag ntawm weld flash, thiab tag nrho kev huv ntawm cov weld. Ib qho kev tsis sib xws xws li cov kab nrib pleb, cov duab tsis zoo, lossis kev sib tsoo ntau dhau yuav tsum raug sau tseg rau kev ntsuam xyuas ntxiv.
2. Weld Nugget Loj thiab Zoo:
Qhov luaj li cas thiab cov duab ntawm lub weld nugget yog qhov qhia txog kev ua haujlwm ntawm lub tshuab vuam. Ib qho zoo-tsim weld nugget feem ntau yog puag ncig lossis oval, nyob ntawm cov duab electrode. Nws yuav tsum muaj qhov loj me me thiab nthuav tawm fusion hla tag nrho cov kev sib koom ua ke. Cov duab tsis zoo lossis qhov sib txawv ntawm qhov loj tuaj yeem teeb pom kev teeb meem nrog lub tshuab teeb tsa lossis electrode hnav.
3. Weld Penetration:
Qhov tob tob yog lwm qhov tseem ceeb ntawm qhov ntsuas. Kev nkag mus kom txaus ua kom muaj kev ruaj khov thiab txhim khu kev qha ntawm cov hlau. Cov kws tshuaj ntsuam xyuas tuaj yeem siv cov txheej txheem xws li hla ntu los ntsuas qhov tob tob kom raug. Kev nkag mus tsis zoo tuaj yeem ua rau cov pob qij txha tsis muaj zog, cuam tshuam cov txheej txheem kev ncaj ncees ntawm cov welded los ua ke.
4. Weld Flash thiab Spatter:
Weld flash, cov khoom raug tshem tawm thaum lub sij hawm vuam, yuav tsum tsawg thiab yooj yim tshem tawm. Ntau dhau flash los yog spatter tuaj yeem ua rau muaj teeb meem zoo, nce kev ntxuav tom qab vuam, thiab muaj peev xwm muaj kev nyab xeeb. Kev teeb tsa lub tshuab kom raug thiab kev saib xyuas electrode tuaj yeem pab txo cov teeb meem no.
5. Weld Strength thiab Integrity:
Kev ntsuam xyuas lub zog ntawm qhov vuam yog ib kauj ruam tseem ceeb hauv kev ntsuam xyuas zoo. Ntau yam kev sim tsis muaj kev puas tsuaj thiab kev puas tsuaj, xws li kev sim tensile thiab khoov kev sim, tuaj yeem ua haujlwm los ntsuas qhov kev ncaj ncees ntawm cov vuam. Cov txiaj ntsig yuav tsum tau ua kom tau raws li lossis tshaj li qhov yuav tsum tau ua kom ntseeg tau tias cov khoom siv tau ntev.
6. Hluav taws xob Parameters:
Kev saib xyuas thiab sau cov ntsuas hluav taws xob thaum lub sij hawm vuam, xws li voltage, tam sim no, thiab lub sijhawm vuam, yog qhov tseem ceeb rau kev tswj kom zoo. Kev sib txawv ntawm qhov teeb tsa tsis tuaj yeem qhia txog teeb meem nrog lub tshuab vuam, electrodes, lossis cov khoom sib xws.
7. Kho thiab Calibration:
Kev saib xyuas tsis tu ncua thiab calibration ntawm cov tshuab vuam tsis zoo yog qhov tseem ceeb rau qhov zoo sib xws. Electrodes yuav tsum tau khaws cia rau hauv qhov zoo, thiab lub tshuab teeb tsa yuav tsum tau tshawb xyuas thiab kho raws li qhov xav tau.
8. Kev khaws cia:
Kev tuav cov ntaub ntawv ntxaws ntxaws ntawm txhua qhov kev ua haujlwm vuam yog qhov tseem ceeb rau kev taug qab thiab kev tswj kom zoo. Cov ntaub ntawv no yuav tsum muaj cov ntaub ntawv hais txog kev teeb tsa lub tshuab, cov ntaub ntawv siv, thiab kev tshuaj ntsuam xyuas. Yog tias muaj teeb meem lossis teeb meem, cov ntaub ntawv khaws cia zoo tuaj yeem pab txheeb xyuas cov hauv paus hauv paus thiab siv cov kev kho kom raug.
Hauv kev xaus, ua kom ntseeg tau qhov zoo ntawm cov ntsiab lus weld hauv cov tshuab vuam vuam yog qhov tseem ceeb rau kev tsim cov khoom lag luam txhim khu kev qha thiab nyab xeeb. Cov txheej txheem tshuaj xyuas tag nrho, suav nrog kev kuaj pom, ntsuas qhov ntsuas qhov tseem ceeb, thiab kuaj xyuas lub zog thiab kev ncaj ncees, pab tswj cov txheej txheem siab ntawm vuam zoo. Kev saib xyuas tsis tu ncua thiab cov ntaub ntawv khaws cia ntxiv txhawb nqa tag nrho cov txheej txheem tswj kev ua tau zoo, kom ntseeg tau tias kev siv vuam txuas ntxiv yog qhov muaj zog thiab muaj kev ntseeg siab koom nrog hauv ntau yam kev lag luam.
