Yuav ua li cas kom ntseeg tau tias Airtightness ntawm Weld Seam? Nws puas tuaj yeem xeem dhau Helium Test lossis ntsuas dej siab?

Txhawm rau xyuas kom lub airtightness ntawm lub tsheb nyias phaj welds thiab pab kom lawv dhau helium lossis dej siab ntsuas, cov kev ntsuas coj los ntawm peb theem: ua ntej vuam, txheej txheem vuam, thiab tom qab vuam, raws li hauv qab no:

ua ntej vuam

Kev xaiv thiab ua cov khoom siv

Xaiv cov ntaub ntawv tsim nyog: xyuas kom meej tias qhov zoo thiab kev ua tau zoo ntawm lub tsheb nyias daim hlau thiab cov khoom siv vuam (xws li vuam hlau) ua tau raws li qhov yuav tsum tau muaj, muaj qhov zoo weldability thiab corrosion kuj. Piv txwv li, xaiv cov vuam hlau uas muaj silicon, manganese thiab lwm yam khoom tuaj yeem txhim kho qhov ntom ntawm cov vuam seam.

Kev ntxuav saum npoo: Ua tib zoo tshem cov roj stains, xeb, oxide nplai, thiab lwm yam impurities los ntawm qhov chaw ntawm cov phaj nyias nyias kom tsis txhob muaj qhov tsis xws luag xws li porosity los ntawm kev cuam tshuam rau huab cua nruj thaum lub sijhawm vuam. Kev siv tshuaj ntxuav, tshuab polishing, thiab lwm yam tuaj yeem siv tau.

Kev tshuaj xyuas cov khoom siv vuam vuam

Cov cuab yeej debugging: Ua ib qho kev tshuaj xyuas thiab kev debugging ntawm cov khoom siv vuam kom ruaj khov, xws li qhov tseeb thiab ruaj khov ntawm cov mem tes zaus, tam sim no amplitude, thiab lwm yam ntawm cov khoom siv pulse vuam.

Kev tshuaj ntsuam xyuas roj: Yog siv cov roj shielded vuam, lub purity thiab ntws stability ntawm cov shielding roj yuav tsum tau guaranteed. Piv txwv li, argon roj uas muaj purity tsis tsawg tshaj li 99.99% yuav tsum tau siv los ua cov roj thaiv kev tiv thaiv kom tsis txhob muaj cua nkag mus rau hauv cov vuam thiab tsim cov pores.

vuam

Optimization ntawm vuam parameter

Kev tswj cov khoom siv hluav taws xob: Kho qhov vuam lub zog tsim nyog raws li qhov tuab thiab cov khoom siv ntawm cov phaj nyias, xws li lub siab dav thiab lub ncov tam sim no ntawm cov mem tes vuam, vuam tam sim no thiab qhov hluav taws xob ntawm kev sib txuas txuas ntxiv, thiab lwm yam, kom tsis txhob hlawv los ntawm lub zog ntau dhau los yog tsis tiav fusion tshwm sim los ntawm lub zog tsis txaus.

Vuam ceev: Xaiv qhov tsim nyog vuam ceev kom ntseeg tau tias tsim tau zoo ntawm vuam seam. Feem ntau hais lus, kev sib txuas qeeb qeeb yuav ua rau overheating thiab coarse grain loj ntawm weld seam, cuam tshuam rau huab cua nruj; Yog tias qhov nrawm nrawm dhau, qhov tsis xws li vuam tsis tiav yuav tshwm sim.

Vuam kev ua haujlwm specifications

Tuav lub kaum sab xis thiab lub ntsej muag zoo: Khaws lub vuam pas nrig lossis rab phom vuam ntawm lub kaum sab xis nrog rau qhov chaw ua haujlwm kom ntseeg tau tias qhov sib xyaw ua haujlwm zoo ntawm cov vuam thiab tsis txhob muaj qhov tsis xws luag xws li undercutting thiab slag suav nrog.

Tswj cov duab thiab qhov loj ntawm cov weld seam: xyuas kom meej qhov dav thiab qhov siab ntawm lub vuam seam, kev hloov du, thiab tsis txhob sib npaug qhov dav thiab qhov siab ntawm qhov vuam seam, uas cuam tshuam rau qhov ntom ntawm weld seam.

Tom qab Vuam

Kev kuaj pom ntawm welds

Kev tshuaj xyuas qhov muag: Ua qhov kev tshuaj xyuas qhov muag pom ntawm cov weld seam, saib seb puas muaj qhov tsis xws luag xws li cov kab nrib pleb, qhov pores, thiab undercutting ntawm qhov chaw ntawm weld seam, thiab tam sim ntawd ntes thiab cuam tshuam nrog weld seams uas tsis ua tau raws li qhov yuav tsum tau ua.

Dimensional ntsuas: Ntsuas qhov dav, qhov siab, thiab lwm qhov ntev ntawm vuam seam kom ntseeg tau tias nws ua tau raws li qhov yuav tsum tau ua. Rau cov welds uas tsis tau raws li qhov yuav tsum tau, kev kho lossis kho vuam yuav tsum tau ua.

NDT

Kev kuaj helium: Siv lub siab permeability ntawm helium roj, helium roj tau ntim rau hauv qhov chaw welded sab hauv, thiab helium detection kua yog siv rau saum npoo ntawm lub vuam los yog helium huab hwm coj spectrometer leak detector yog siv los xyuas seb puas muaj helium roj to. Yog tias kuaj pom cov pa roj helium, cov pa xau tau raug cim thiab kho.

Kev ntsuas dej siab: Sau cov welded ib feem nrog dej, siv lub siab, thiab tswj nws rau lub sijhawm. Saib xyuas seb puas muaj dej seepage los yog to ntawm qhov chaw ntawm lub vuam. Rau cov khoom uas muaj dej, kho lawv nrog vuam thiab rov ua dua kom txog thaum lawv dhau.

Kho kho

Txheeb xyuas qhov ua rau muaj qhov tsis xws luag: Rau cov teeb meem pom hauv kev ntsuas helium lossis kev ntsuas dej siab, txheeb xyuas cov laj thawj ntawm qhov tsis xws luag, xws li kev siv vuam tsis raug, kev ua haujlwm tsis raug, thiab lwm yam, thiab siv cov phiaj xwm kev txhim kho.

Kho vuam thiab polishing: Kev kho vuam yuav tsum tau ua nyob rau ntawm qhov tsis xws luag, thiab tom qab kho vuam, polishing kev kho mob yuav tsum tau ua kom lub npoo ntawm cov vuam du thiab hloov zoo nrog cov khoom siv puag ncig. Kev tshuaj xyuas yuav tsum tau ua kom txog thaum lub airtightness ntawm lub vuam tsim nyog.

Los ntawm cov kev ntsuas saum toj no, lub airtightness ntawm automotive nyias phaj welds tuaj yeem ua tau zoo, ua kom lawv dhau helium lossis dej siab ntsuas kom ntseeg tau thiab ua tau raws li qhov yuav tsum tau ua ntawm kev tsim tsheb.
