Vuam, ua cov txheej txheem tseem ceeb hauv kev tsim khoom niaj hnub, cuam tshuam ncaj qha rau cov khoom lag luam kev nyab xeeb thiab kev ntseeg siab. Kev tshuaj xyuas vuam khiav thoob plaws tag nrho cov txheej txheem tsim khoom, txheeb xyuas qhov tsis xws luag thiab txheeb xyuas qhov ua tau zoo, ua qhov cuam tshuam tseem ceeb los xyuas kom muaj cov khoom ua tau raws li cov qauv.
Kev tshuaj xyuas pib nrog ua ntej- kev txheeb xyuas kev npaj vuam. Qhov no suav nrog kev lees paub cov ntaub ntawv pov thawj thiab cov lus qhia tshwj xeeb ntawm cov khoom siv hauv paus thiab cov khoom siv vuam, tshuaj xyuas qhov tseeb ntawm qhov beveling, huv huv, thiab sib dhos qhov sib txawv, thiab xyuas qhov ua tau raws li qhov sib txawv ntawm cov khoom siv vuam cov txheej txheem nrog cov ntaub ntawv txheej txheem. Cov theem no yog thawj kab ntawm kev tiv thaiv tsis xws luag, tiv thaiv cov teeb meem zoo tom ntej los ntawm kev sib txawv ntawm cov xwm txheej hauv paus.
Hauv - kev soj ntsuam vuam tsom rau kev tswj cov txheej txheem. Rau qhov tseem ceeb welds lossis siab - cov txheej txheem kev pheej hmoo, tiag- lub sijhawm soj ntsuam thev naus laus zis taug qab qhov ruaj khov ntawm cov vuam tsis sib xws (xws li tam sim no, qhov hluav taws xob, thiab cov cua kub nkag), saib xyuas lub pas dej molten morphology thiab interpass kub, thiab kho tam sim ntawd kev ua haujlwm sib txawv. Rau cov khoom siv tseem ceeb, cov qauv nruab nrab tuaj yeem ua tau siv tsis yog -kev kuaj kev puas tsuaj (NDT), xws li kev ntsuas nkag mus, txhawm rau txheeb xyuas cov microcracks saum npoo thiab tiv thaiv kev puas tsuaj.
Tom qab- kev tshuaj xyuas vuam yog qhov txuas tseem ceeb hauv kev ntsuas kev ua tau zoo, feem ntau muab faib ua kev tshuaj xyuas qhov muag thiab kev tshuaj xyuas sab hauv. Kev soj ntsuam pom pom muaj qhov pom kev soj ntsuam qhov sib txuas, kev sib txuas ntawm cov khoom siv, kev txiav, thiab lwm yam tsis xws luag hauv qhov chaw uas siv lub iav magnifying, thiab ntsuas qhov sib txawv ntawm qhov sib txawv. Kev tshuaj xyuas sab hauv siv kev ntsuas hluav taws xob (RT), kuaj ultrasonic (UT), lossis kuaj cov khoom sib nqus (MT) raws li tus qauv xav tau. Cov yav tas los qhia meej meej txog qhov tsis xws luag (xws li porosity thiab inclusions), thaum lub tom kawg yog rhiab rau saum npoo thiab ze ntawm - cov kab nrib pleb. Rau cov welded Cheebtsam uas raug rau dynamic loads los yog high pressures, mechanical kev ntsuam xyuas, xws li tensile, dabtsi yog khoov, thiab tej yam kev ntsuam xyuas, kuj yuav tsum tau xyuas kom meej tias cov sib koom ua ke lub zog thiab toughness raws li cov qauv.
Thaum kawg, tag nrho cov ntaub ntawv tshuaj xyuas yuav tsum tau sau tag nrho, tshuaj xyuas, thiab tshuaj xyuas los txiav txim siab ua raws. Tsis yog-cov khoom tsis sib haum yuav tsum muaj lawv qhov tsis xws luag rov qab mus rau lawv qhov laj thawj, thiab kaw- kev tswj lub voj voog siv los ntawm cov txheej txheem hloov kho, rov ua dua, lossis tshem tawm.
Cov txheej txheem kev soj ntsuam welded ua raws li lub hauv paus ntsiab lus ntawm "kev tiv thaiv ua ntej, tag nrho- cov kev pabcuam saw," siv ntau-cov txheej txheem kev ua haujlwm thiab cov txheej txheem nruj nruj los tsim lub hauv paus ruaj khov rau kev nyab xeeb ntawm cov khoom siv hauv kev lag luam thiab yog ib qho kev txhawb nqa tseem ceeb rau kev ua haujlwm siab - kev txhim kho kev lag luam.
