Yuav ua li cas los kuaj weld zoo tom qab vuam

Hauv Huayas Huayang Steel Yeeb Nkab Tuam Txhab, tom qab vuam yog ua tiav, peb yuav siv ntau yam khoom ua tau tias cov khoom ua tau zoo, raws li nram no:

Kev soj ntsuam pom:Cov kws tshaj lij yuav ncaj qha rau kev soj ntsuam weld nrog lub ntsej muag zoo nkauj, nrawm, tsis tiav ntawm Weld tau ua tiav cov cai tsim nyog, thiab seb qhov kev hloov pauv tau zoo.

Kev Ntsuas Cov Khoom Ntsuas:Siv cov cuab yeej xws li Weld Soj ntsuam ntsuas kom ntsuas qhov loj me xws li qhov siab tshaj, dav thiab offset ntawm weld kom ntseeg tau tias nws yog nyob rau hauv qhov kev ua kom tau txais ntau yam.

Radicegraphic nrhiav kom tau (RT)

Siv X-Ray lossis-Ermin kom nkag mus rau hauv Weld (xws li cov duab weld (attled) Los ntawm kev soj ntsuam thiab kev txheeb xyuas cov duab ntawm zaj duab xis, seb puas muaj qhov tsis xws luag nyob hauv Weld thiab cov hom, ntau thiab cov kev tsis xws luag tuaj yeem raug txiav txim.

Nws yog tsuas yog siv los tshawb xyuas lub ntim tsis xws nyob hauv Weld, thiab muaj qhov siab rhiab los kuaj pom xws li porosity thiab sluag inclusion.

Tus ultrasonic khuam cov tshuaj ntsuam pom tseeb emits ultrasonic nthwv rau hauv Weld. Thaum Ultrasonic nthwv dej nthuav dav nyob rau hauv Weld, nws yuav tau cuam tshuam, tsim tawm thiab tawg thaum nws ntsib qhov tsis xws luag. Lub ntsuas tau txais cov cim qhia ultrasonic, hloov nws mus rau hauv lub cim hluav taws xob, thiab qhia txog cov nplaim hluav taws xob. Raws li cov yam ntxwv thiab cov tsis sib haum ntawm cov nthwv dej, nws tuaj yeem txiav txim seb puas muaj qhov tsis xws luag nyob hauv Weld thiab qhov loj me thiab qhov loj me thiab qhov loj me thiab qhov loj me.

Nws muaj qhov siab dua los kuaj xyuas cov nplaim hluav taws xob xws li cov kab nrib pleb, thiab cov nqi tau nrawm thiab cov neeg soj ntsuam kom muaj kev paub nplua nuj thiab kev paub.

Nws yog qhov haum rau kev kuaj pom yam tsis xws luag nyob rau saum npoo thiab ze ntawm cov ntaub ntawv ferromagnetic. Nws muaj siab nrhiav tau rau cov kab nrib pleb, cov plaub hau, quav thiab lwm yam tsis xws luag rau lossis ze ntawm Weld nto.

Tom qab ntxuav lub weld nto, thov sib nqus hmoov los yog sib nqus ncua kev ncua ntawv rau saum npoo. Thaum muaj qhov tsis xws li ntawm qhov chaw lossis ze rau ntawm qhov chaw, vim muaj kev hloov ntawm qhov tsis xws luag, thiab cov hmoov sib nqus yuav tau adsorbed los ua cov cim sib nqus. Cov kev puas tuaj yeem raug txiav txim los ntawm kev saib cov duab, qhov loj me thiab faib cov cim sib nqus.

Nws yog tsuas yog siv los kuaj cov chaw saum npoo av qhib cov khoom tsis zoo ntawm cov ntaub ntawv uas tsis pom. The penetrant containing color dye or fluorescent agent is coated on the weld surface to make it penetrate into the defect, then the excess penetrant is removed, and then the developer is coated, so that the penetrant in the defect is adsorbed to the surface to form a display trace, and the existence and position of the defect can be judged by observing the display trace.

Tsis xws luag xws li cov kab nrib pleb, pinholes thiab looseness ntawm Weld deg yuav tsis tuaj yeem kuaj pom, thiab kev nrhiav cov txiaj ntsig hauv Weld nrog cov npoo av lossis roj av muaj ntau.

Tensile xeem:Lub tensile ua qauv yog txiav los ntawm Weld thiab sim ntawm lub tshuab kuaj sim Tensile los txiav txim siab lub zog ntawm weld hlau, thiab ntsuas kev ua haujlwm ntawm Weld nyob rau hauv kev nro.

Dabtsi yog khoov xeem:Los ntawm khoov cov qauv Weld, tshawb xyuas seb puas muaj cov kab nrib pleb thiab lwm yam tsis xws luag hauv Weld thaum khoov, thiab ntsuas cov plastonity thiab kev nruj ntawm Weld.

Kev Ntsuas Qhov Kev Ntsuas:Weld qauv nrog notch yog raug rau kev sim ua haujlwm ntawm Weld hlau, muaj kev cuam tshuam lub pob txha tsis kam ntawm weld nyob rau hauv kev cuam tshuam load.

metallographic tsom xam

Lub Weld thiab tshav kub cuam tshuam tau ntu los ntawm Metalographic, xws li Motaltructure los ntawm kev sib tw Weld

Tshuaj Muaj Kev Ntsuam Xyuas Kev Ntsuam Xyuas

Los ntawm txoj kev txheeb xyuas cov tshuaj lom neeg ntawm Weld hlau tau kuaj pom tias cov ntsiab lus ntawm ntau cov alloy cov ntsiab lus hauv Weld yuav tsum tau, yog li ua kom muaj kev ua tau zoo thiab zoo WELD.
