Cov kav dej ua tiav kauv hlau yuav tsum tau kuaj pom. Kev tshuaj xyuas qhov muag ntawm cov pob qij txha welded yog ib txoj hauv kev yooj yim feem ntau tsom rau kev txheeb xyuas qhov tsis xws ntawm qhov vuam thiab qhov sib txawv ntawm qhov sib txawv. Qhov no tuaj yeem ua tau ncaj qha los ntawm kev soj ntsuam thiab nrog kev pab ntawm cov ntsuas, tsom iav, thiab lwm yam cuab yeej. Yog hais tias muaj me ntsis tsis xws luag nyob rau saum npoo ntawm weld seam, muaj feem yuav muaj qhov tsis xws luag nyob rau hauv lub weld ib yam nkaus.
Txoj Kev Tshuaj Xyuas Lub Cev: Cov qauv tshuaj xyuas lub cev siv ntau yam tshwm sim ntawm lub cev rau kev ntsuas lossis kev kuaj xyuas. Kev tshawb pom ntawm qhov tsis xws luag hauv cov ntaub ntawv lossis cov khoom ua haujlwm feem ntau yog ua los ntawm kev kuaj tsis yog kev puas tsuaj (NDT), uas suav nrog kev kuaj ultrasonic, kuaj radiographic, kuaj kua penetrant, kuaj magnetic particle, thiab lwm yam.
Surface Judgement, lossis Visual Inspection: Kev tshuaj xyuas qhov muag ntawm cov pob qij txha yog ib qho yooj yim tab sis siv dav hauv kev tshuaj xyuas thiab yog ib feem tseem ceeb ntawm kev tshuaj xyuas cov khoom kawg. Nws feem ntau tsom rau kev txheeb xyuas qhov tsis xws luag thiab qhov txawv txav ntawm qhov chaw ntawm weld seams. Qhov no feem ntau yog ua los ntawm kev pom qhov muag, nrog kev pab ntawm cov qauv qauv, ntsuas ntsuas, tsom iav, thiab lwm yam cuab yeej. Yog hais tias muaj teeb meem tshwm sim nyob rau saum npoo ntawm weld seam, muaj peev xwm rau defects nyob rau hauv lub weld thiab.
Kev Ntsuas Lub Zog ntawm Cov Nkoj Siab: Ntxiv nrog rau cov kev ntsuas xau, cov hlab ntsha siab tau kuaj xyuas lub zog. Muaj ob hom kev sim hydraulic thiab pneumatic xeem. Ob txoj kev tuaj yeem txheeb xyuas qhov nruj ntawm cov welds hauv cov thawv thiab cov kav dej ua haujlwm hauv siab. Kev ntsuas pneumatic yog qhov rhiab heev thiab nrawm dua li kev ntsuas hydraulic, thiab cov khoom kuaj tsis tas yuav tsum muaj cov dej ntws tawm, ua rau nws tsim tshwj xeeb rau cov khoom uas muaj cov dej ntws tsis zoo. Txawm li cas los xij, kev sim pneumatic ua rau muaj kev pheej hmoo siab dua li kev sim hydraulic. Thaum kuaj, nws yog ib qho tsim nyog yuav tsum ua raws li kev ntsuas kev nyab xeeb los tiv thaiv kev sib tsoo.
Hauv cov ntsiab lus, cov no yog cov kev tshuaj xyuas rau cov kav me me-inch kauv steel kav. Txhawm rau kom muaj kev nyab xeeb ntawm cov txheej txheem tshuaj xyuas, nws yog ib qho tsim nyog rau cov kws tshaj lij los ua qhov kev ntsuam xyuas hauv ib puag ncig kev tshuaj ntsuam xyuas, yog li tiv thaiv qhov tshwm sim ntawm cov xwm txheej txaus ntshai.
