Yuav ua li cas kom ntseeg tau tias lub airtightness ntawm Weld Seam? Puas yog nws mus kuaj mob siab lossis sim dej?

Yuav kom ntseeg tau lub airtightness ntawm tsheb nyias phaj welds thiab txhawb lawv kom lawv cov theem siab yuav raug coj los ntawm peb ntu, vuam vuam, thiab ncej vuam, raws li hauv qab no:

Kev Xaiv Xaiv thiab Kev Ua

Xaiv cov ntaub ntawv tsim nyog: xyuas kom meej tias qhov zoo thiab ua tau zoo ntawm cov xov hlau nyias thiab cov ntaub ntawv vuam (xws li weldability vuam thiab corrosion tsis kam. Piv txwv li, xaiv vuam hlau hlau muaj silicon, manganese thiab lwm cov ntsiab lus tuaj yeem txhim kho qhov ntom ntawm Weld Seam.

Tu kom tu: kom huv si tshem cov roj stains, xeb, thiab lwm yam impurities los ntawm kev cuam tshuam cua los ntawm kev cuam tshuam cua nruj thaum lub ntsej muag. Kev Siv Tshuaj Siv Tshuaj, Kev Siv Kho Tshuab Polishing, thiab lwm cov hau kev tuaj yeem siv.

Vuam Cov Khoom Siv Khoom Siv Khoom

Khoom rhiab debugging: Ua kev soj ntsuam ntau dua, xws li cov haujlwm muaj peev xwm thiab cov khoom siv tau yooj yim, thiab lwm yam ntawm cov khoom siv pulse vuam.

Kev soj ntsuam roj kev soj ntsuam: yog tias cov hluav taws xob thaiv hluav taws xob vuam siv, lub purity thiab txaus ntawm cov ntaub thaiv hluav taws xob yuav tsum ua kom zoo nkauj. Piv txwv li, kev sib cav sib ceg nrog lub purity tsis tsawg tshaj li 99.99% yuav tsum tau siv los ua kev thaiv pa los tiv thaiv cua los ntawm kev nkag mus rau Weld thiab txoj kev sib tw.

Kev ua kom zoo ntawm vuam tsis

Lub zog ua hluav taws xob tswj: kho qhov chaw tsim hluav taws xob tsim nyog raws li cov phaj tuab thiab hluav taws xob ntawm cov pulse txuas ntxiv, thiab siv lub zog tsis sib xws los ntawm kev siv hluav taws xob tsis tas los ntawm lub zog tsis txaus.

Vuam ceev: Xaiv cov vuam qhov tsim nyog kom ntseeg tau tias tsim kom zoo ntawm Weld Seam. Feem ntau hais lus, qeeb qeeb vuam ceev yuav ua rau muaj kev kub ntxhov thiab coarse tsoo loj ntawm Weld Seam, cuam tshuam rau huab cua nruj; Yog tias qhov nrawm nrawm dhau, tsis muaj xws li ua tiav cov vuam vuam tsis tiav.

Vuam Ua Haujlwm Kev Lag Luam

Saib xyuas kom tsim nyog lub kaum sab xis thiab tshaj tawm cov kab hlau: khaws phom rau qhov chaw ua haujlwm kom paub meej txog qhov tsis zoo xws li undercutting thiab slag suav nrog.

Tswj cov duab thiab qhov loj me ntawm Weld Seam: kom cov qhov dav dav dav thiab qhov siab tsis sib xws, uas cuam tshuam rau lub ntom ntom ntawm Weld Seam.

Kev Ntsuam Xyuas Cov Welds

Kev Ntsuam Xyuas Pom: Ua cov leeg pom ntawm Weld Seam, pom tias muaj qhov sib tsoo ntawm Weld, thiab cuam tshuam nrog Weld Seams uas tsis tau raws li cov kev xav tau.

Kev ntsuas qhov dav: Ntsuas qhov dav, qhov siab, thiab lwm qhov ntev ntawm Weld Seam kom ntseeg tau tias nws ua tau raws li cov kev tsim qauv. Rau Welds uas tsis tau raws li qhov tseem ceeb, kho lossis kho cov vuam vuam yuav tsum tau ua.

Kuaj Helium, siv cov pa roj helium, helium pa tau sau rau saum npoo Weld, thiab siv Helium Gass Spectrometer yog siv los tshawb xyuas seb puas muaj kev txhawb siab pab helium. Yog tias muaj txiaj ntsig Gelium pa roj yog kuaj pom, lub chaw so taw yog cim thiab kho.

Kuaj cov dej siab: Sau qhov welded feem nrog dej, siv rau qee lub siab, thiab tswj nws rau ib lub sijhawm. Saib seb puas muaj dej txaus los yog xau rau saum npoo ntawm Weld. Rau cov seem nrog to feakage, kho lawv nrog vuam thiab rov qab los txog thaum lawv dhau mus.

Kev Tiv Thaiv Kho

Txheeb xyuas cov laj thawj tsis xws luag: Rau cov teeb meem pom hauv helium kuaj cov teeb meem, xws li lwm yam yuam kev, kev ntsuas kev ntsuas rau kev txhim kho.

Kho Welding thiab Polishing: Kev Kho Vuam Vuam yuav tsum tau nqa tawm ntawm qhov tsis xws luag, thiab tom qab kev kho kom zoo nkauj yuav tsum tau ua kom lub weld du thiab kev hloov pauv zoo nrog ib puag ncig cov khoom siv. Rov tshawb nrhiav dua kom txog thaum lub airtightness ntawm weld yog tsim nyog.

Los ntawm cov saum toj no cov kev ntsuas, lub airtightness ntawm cov phaj nyias nyias welds tuaj yeem ua kom tiav helium lossis ua kom muaj raws li kev tsim khoom lag luam.
