Yuav ua li cas yog weld tsis muaj kev soj ntsuam tau nqa tawm?
Nyob rau hauv E10210 tus qauv, tsis muaj kev sim ua phem (NDT) ntawm Welds yog qhov txuas tseem ceeb kom ntseeg tau tias qhov zoo welolled profiles. Cov hauv qab no yog cov qauv tshwj xeeb thiab cov kev xav tau rau kev sim ua tsis yog-kev ua phem rau Welds hais hauv EN10210 tus qauv:
Cov Kev Xav Tau General:
Thaum tsis muaj kev ua phem rau cov welds ntawm welded cov qauv heel hlau hollow, nws yuav tsum tau ua raws li tshooj 9.4 ntawm en {3}}: 2006. Cov neeg tsim khoom tuaj yeem txiav txim siab seb cov voj voos ua ntej kev sib nqus ua ntej kev sib xyaw zaum kawg, lossis ntawm ib puag ncig lossis duab plaub lossis lub retal hollow profile tom qab ua kom kawg molding.
Fais Weld:
Kev tshuaj ntsuam ntawm hluav taws fais fab yuav tsum ua raws ib qho ntawm cov qauv hauv qab no European:
En 10246-3, lees txais qib E4 tab sis tsis pub siv lub raj raj / Disc cheat cuab lawm;
En 10246-5, txais qeb F5;
En 10246-8, txais qib u5
Submerged Arc Vuam Sib Koom Tes
Submerged Arc Vuam cov pob qij txha yuav tsum tau kuaj xyuas raws li en {{{}, kev tshuaj xyuas qib U4}}, duab zoo qib R2.
Taub pob hauv Welds siv los koom nrog Sawb / Phaj ntev raug tso cai nyob rau hauv cov txheej txheem raberging arc
Tsis yog-kev sim ua haujlwm
Feem ntau siv cov kev sim tsis ua haujlwm xws li kev sim tshuaj $
Kev kuaj kom tau txais kev siv tshuab ultrasonic ntawm cov yam ntxwv ntawm cov khoom siv hluav taws xob siab tsis pom qhov tsis xws hauv Weld, uas haum rau vuam seams nrog cov tuab loj.
X-ray soj ntsuam siv x-rays lossis gamma rays mus rau kom nkag mus rau weld thiab saib tsis zoo rau ntawm cov duab tsim tom qab lub rays txeem cov khoom
Weld Chaw Zoo Tshaj
Qhov chaw zoo ntawm weld tuaj yeem pom nrog lub qhov muag liab qab lossis nrog lub khob iav loj; Tsis yog-ua kev puas tsuaj ntawm Weld cov ntsiab lus tsis xws luag thev naus laus zis, cov qauv ultrasonic, txheej txheem sib nqus, txoj kev nkag mus thiab lwm yam.
Los ntawm cov hau kev no, sab hauv thiab saum npoo thiab saum npoo ntawm Weld tuaj yeem raug kuaj pom zoo los xyuas kom zoo thiab kev nyab xeeb ntawm cov qauv vuam. Kev sim siab tsis tseem ceeb yog ib feem tseem ceeb ntawm vuam kev tswj hwm zoo, thiab nws yog ib qho tseem ceeb heev kom ntseeg tau kev ntseeg tau thiab kev nyab xeeb ntawm cov qauv.
