Resistance welding yog cov txheej txheem tsim khoom siv dav siv, paub txog nws cov txiaj ntsig thiab kev ntseeg siab hauv kev koom nrog cov hlau. Ua kom ntseeg tau qhov zoo ntawm cov khoom siv welded yog qhov tseem ceeb hauv ntau qhov kev lag luam, los ntawm tsheb mus rau aerospace. Hauv tsab xov xwm no, peb yuav tham txog cov ntsiab lus tseem ceeb ntawm kev tshuaj xyuas qhov vuam zoo ntawm cov tshuab vuam vuam.
- Kev tshuaj xyuas qhov muag: Thawj kauj ruam hauv kev tswj kom zoo yog kev soj ntsuam pom ntawm cov pob qij txha welded. Cov kws tshuaj ntsuam xyuas qhov tsis sib xws xws li tawg, voids, lossis tsis tiav fusion. Weld seams yuav tsum du thiab tsis muaj qhov tsis xws luag.
- Dimensional soj ntsuam: Precision yog qhov tseem ceeb hauv ntau daim ntawv thov, yog li ntsuas qhov ntev ntawm qhov chaw welded yog qhov tseem ceeb. Qhov no ua kom ntseeg tau tias cov khoom kawg ua raws li cov lus qhia tshwj xeeb.
- Weld Strength Test: Lub zog ntawm lub vuam yog qhov tseem ceeb ntawm qhov tsis zoo. Qhov no tuaj yeem raug soj ntsuam los ntawm kev kuaj kev puas tsuaj lossis tsis muaj kev puas tsuaj, nrog rau kev sib tw tensile, khoov, lossis kev ntsuas shear.
- Kev kuaj Ultrasonic: Rau kev ntsuam xyuas tsis muaj kev puas tsuaj, kev kuaj ultrasonic feem ntau yog ua haujlwm. Nws siv lub suab nrov nthwv dej kom pom qhov tsis xws luag lossis tsis sib xws hauv qhov vuam.
- Kev soj ntsuam hluav taws xob: Radiography yog lwm cov txheej txheem uas tsis muaj kev puas tsuaj uas muab cov ncauj lus kom ntxaws ntawm cov weld tus qauv sab hauv. Nws yog qhov tshwj xeeb tshaj yog siv rau cov ntaub ntawv tuab lossis cov ntawv thov tseem ceeb.
- Macroscopic Examination: Qhov no suav nrog kev hla ntu ib qho piv txwv ntawm cov vuam los tshuaj xyuas nws cov qauv sab hauv hauv lub tshuab ntsuas. Nws pab txheeb xyuas cov teeb meem xws li kev nkag mus tsis raug lossis porosity ntau dhau.
- Vuam Txheej Txheem Saib Xyuas: Ntau lub tshuab vuam niaj hnub no tau nruab nrog cov ntsuas ntsuas thiab ntsuas ntsuas uas tsis tu ncua taug qab tsis zoo li tam sim no, qhov hluav taws xob, thiab lub sijhawm vuam. Deviations los ntawm kev teeb tsa muaj nuj nqis tuaj yeem qhia qhov teeb meem zoo ntawm vuam.
- Electrode Maintenance: Kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas ntawm vuam electrodes yog qhov tseem ceeb. Hnav los yog puas electrodes tuaj yeem ua rau cov vuam tsis zoo.
- Cov ntaub ntawv zoo: Khaws cov ntaub ntawv ntxaws ntxaws ntawm tag nrho cov kev ntsuas vuam thiab kev soj ntsuam xyuas yog qhov tseem ceeb rau kev taug qab thiab txhim kho cov txheej txheem.
- Kev cob qhia neeg ua haujlwm: Cov neeg ua haujlwm txawj ntse ua lub luag haujlwm tseem ceeb hauv kev tswj cov vuam zoo. Kev cob qhia kom raug thiab cov ntawv pov thawj kom ntseeg tau tias cov neeg ua haujlwm nkag siab txog cov txheej txheem vuam thiab tuaj yeem daws teeb meem.
Hauv kev xaus, kev ua kom ntseeg tau qhov zoo ntawm cov khoom siv vuam vuam tshuab yog qhov tseem ceeb kom ua tau raws li cov qauv kev lag luam thiab tsim cov khoom siv txhim khu kev qha. Kev sib xyaw ua ke ntawm kev kuaj pom, ntau yam kev sim, thiab kev tsom mus rau cov txheej txheem tswj thiab kev saib xyuas pab ua kom zoo ib yam, zoo welds. Kev nqis peev hauv kev tswj hwm tsis yog tsuas yog txo qhov tsis xws luag thiab rov ua haujlwm dua, tab sis kuj tseem txhim kho kev nyab xeeb thiab kev ua haujlwm ntawm cov khoom siv welded hauv ntau hom kev siv.
