Resistance qhov chaw vuam yog ib txoj kev siv dav hauv kev tsim khoom, tshwj xeeb tshaj yog nyob rau hauv kev lag luam tsheb thiab aerospace, qhov chaw sib koom ntawm cov khoom siv hlau yog qhov tseem ceeb rau kev ncaj ncees. Ua kom ntseeg tau tias qhov zoo ntawm cov welds no yog qhov tseem ceeb tshaj plaws, thiab ib qho tseem ceeb ntawm cov txheej txheem kev ruaj ntseg zoo no yog kev tshuaj xyuas ntawm cov vuam nkag.
Taw qhia:Resistance spot welding yog txheej txheem uas koom nrog cov hlau los ntawm kev siv lub zog thiab hluav taws xob tam sim no los tsim kom muaj kev sib raug zoo. Txhawm rau ntsuas qhov ncaj ncees ntawm cov welds, nws yog ib qho tseem ceeb uas yuav tsum tau soj ntsuam seb qhov vuam tob tob tob npaum li cas ntawm cov khoom siv. Cov txheej txheem tshuaj xyuas no pab txheeb xyuas qhov tsis xws luag, xws li kev nkag mus tsis txaus lossis kub hnyiab, uas tuaj yeem cuam tshuam qhov vuam lub zog.
Method of Penetration Inspection:Muaj ntau txoj hauv kev los tshuaj xyuas qhov tob tob ntawm qhov chaw welds:
- Kev tshuaj xyuas qhov muag:Qhov no yog txoj hauv kev yooj yim tshaj plaws thiab suav nrog kev tshuaj xyuas qhov vuam ntawm qhov chaw kom pom qhov tsis xws luag xws li hlawv cov cim, qhov khoob, lossis qhov tsis sib xws. Txawm li cas los xij, txoj kev no tsuas yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam, nws yuav tsum tau muab tshem tawm.
- Kev kuaj hluav taws xob:Kev tshuaj xyuas hluav taws xob siv hluav taws xob xoo hluav taws xob lossis gamma rays los tsim cov duab ntawm lub vuam sab hauv. Txoj kev no muab cov ncauj lus kom ntxaws saib ntawm qhov vuam qhov tob tob thiab txhua qhov tsis xws luag. Nws muaj txiaj ntsig zoo tab sis xav tau cov cuab yeej tshwj xeeb thiab kev txawj ntse.
- Kev kuaj ultrasonic:Kev tshuaj xyuas Ultrasonic suav nrog kev xa cov suab nrov ntau zaus los ntawm cov vuam thiab tshuaj xyuas cov ncha kom txiav txim siab qhov tob tob. Nws yog ib txoj hauv kev uas tsis muaj kev puas tsuaj thiab meej rau kev ntsuam xyuas qhov zoo ntawm vuam.
- Eddy Current Testing:Eddy kev ntsuam xyuas tam sim no siv electromagnetic teb los kuaj xyuas cov kev hloov pauv ntawm cov khoom siv, uas tuaj yeem qhia qhov txawv ntawm kev nkag mus rau weld. Nws yog qhov tshwj xeeb tshaj yog rau kev tshuaj xyuas cov ntaub ntawv uas tsis yog-ferrous.
Qhov tseem ceeb ntawm Kev Tshawb Fawb Kev Tshawb Fawb:Kev nkag tau zoo ntawm weld yog qhov tseem ceeb rau kev ua haujlwm ruaj khov thiab ua haujlwm ntev ntawm cov khoom siv welded. Kev nkag mus tsis txaus tuaj yeem ua rau cov pob qij txha tsis muaj zog, uas tuaj yeem ua tsis tau raws li kev ntxhov siab, uas ua rau muaj kev puas tsuaj loj hauv cov ntawv thov tseem ceeb xws li tsheb thav duab lossis cov qauv dav hlau. Ntawm qhov tod tes, kev nkag mus ntau dhau tuaj yeem ua rau hlawv-los ntawm kev puas tsuaj rau cov khoom nyob ib puag ncig.
Hauv kev xaus, kom ntseeg tau qhov zoo ntawm qhov chaw welds los ntawm kev tshuaj xyuas kev nkag mus yog qhov tseem ceeb rau kev tsim khoom lag luam. Nws pab tswj cov txheej txheem kev ncaj ncees ntawm cov khoom siv welded, tiv thaiv qhov tsis xws luag, thiab thaum kawg ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom tiav. Kev xaiv ntawm txoj kev tshuaj xyuas nyob ntawm ntau yam, nrog rau cov khoom siv welded, qib ntawm precision yuav tsum tau, thiab cov ntawv thov tshwj xeeb. Txawm hais tias siv txoj kev twg los xij, kev tshuaj xyuas kom meej thiab meej yog qhov tseem ceeb hauv cov txheej txheem vuam.
