Thaum argon arc vuam siv los vuam stainless hlau, vim muaj kev sib raug zoo ntawm cov hlau tsis muaj hlau thiab cov pa oxygen, yog tias tsis muaj kev tiv thaiv kev tiv thaiv vuam, cov hlau vuam nyob tom qab tau yooj yim oxidized thaum lub sij hawm vuam, cov ntsiab lus hlau raug hlawv, thiab welding defects yog nquag tshwm sim, uas ua rau cov neeg kho tshuab zog thiab corrosion kuj ntawm weld hlau txo.
Nyob rau hauv argon arc vuam ntawm stainless hlau kav, thiaj li yuav xyuas kom meej lub vuam zoo ntawm lub nraub qaum vuam, yuav tsum tau siv cov kev tiv thaiv zoo.
Argon arc vuam ntawm stainless hlau kav feem ntau txais yuav argon sau rau hauv cov yeeb nkab, tiv thaiv tus kheej vuam hlau ib tug argon-dawb vuam tiv thaiv tus neeg saib xyuas, thiab lwm yam, uas muaj peev xwm tiv thaiv oxidation ntawm lub nraub qaum ntawm weld, thiaj li hais tias tus neeg kho tshuab zog thiab corrosion kuj ntawm weld tuaj yeem lav tau zoo.
Tam sim no peb yuav qhia txog argon-filled rov qab tiv thaiv thiab ceev faj ntawm stainless hlau argon arc welded yeeb nkab.
Argon filling tiv thaiv hauv lub raj
Txoj kev sau argon nyob rau hauv lub raj yog los tiv thaiv oxidation nyob rau sab nraum qab ntawm vuam. Argon filling txoj kev feem ntau suav nrog tag nrho argon filling thiab ib nrab argon filling.
1. Zuag qhia tag nrho argon filling txoj kev
Rau cov kav dej me me lossis cov yeeb nkab luv luv, argon filling tuaj yeem siv tag nrho, uas yooj yim heev.
Txoj kev sau argon tag nrho: muab ob qho tib si xaus nrog daim kab xev nplaum (daim ntawv plhaub, roj hmab phaj, thiab lwm yam), sau cov roj argon los ntawm ib qho kawg ntawm lub raj, thiab ua ib qho 3-5 hli tawm qhov rau saum. ntawm lwm qhov kawg ntawm lub foob, feem ntau yog tiv thaiv lub arc los ntawm kev poob rau hauv lub raj. Argon roj siab siab dhau lawm, ua rau muaj teeb meem hauv arc kaw ntawm cov pob qij txha, thiab muaj kev puas tsuaj xws li qhov pits.
Tsis tas li ntawd, txhawm rau tiv thaiv kom tsis txhob muaj roj ntau ntawm argon los ntawm kev tawm hauv qhov sib txawv ntawm cov khoom sib txawv, daim ntawv daim kab xev tuaj yeem siv los kaw ib ntu ntawm lub nozzle ua ntej, tsuas yog qhov ntev ntawm qhov txuas txuas ntxiv rau cov welder mus txog rau welding tiav.
2. Ib nrab argon filling txoj kev
Thaum cov yeeb nkab txoj kab uas hla loj thiab cov kav dej ntev ntev, yog tias argon ncaj qha mus rau hauv cov yeeb nkab, qhov vuam zoo tsis yooj yim los lav, thiab cov argon ntau yuav raug nkim, uas yuav ua rau tus nqi tu.
Yuav kom txuag tau argon, ib nrab argon tuaj yeem siv tau. Ib nrab argon tuaj yeem sau nrog dej-soluble ntawv. Ua ntej qhov kev sib dhos, muab cov ntawv dej-soluble rau ob sab ntawm cov yeeb nkab ntawm qhov deb ntawm 150 mm los ntawm qhov chaw nres nkoj vuam los tsim cov txheej thaiv ib ntus, thiab tom qab ntawd sau cov yeeb nkab nrog cov roj argon ntawm qhov sib txawv ntawm cov chaw nres nkoj.
Thaum cov kav dej tau txais kev sim hydrostatic, cov ntawv dej-soluble yuav sai sai yaj hauv dej thiab raug tso tawm nrog dej yam tsis muaj kev phom sij. Tsis tas li ntawd, ib qho argon-filled fixture tuaj yeem ua rau kev tiv thaiv ib nrab ntawm argon. Ua ntej welding, muab cov ntawv thaiv ntawm cov argon-filled fixture ntawm ob sab ntawm cov yeeb nkab, thiab rub lub fixture tawm ntawm cov yeeb nkab tom qab vuam. Txoj kev no yog tsim rau hauv av prefabrication ntawm stainless hlau kav thiab yog yooj yim thiab yooj yim rau siv.
Kev txiav txim ntawm argon tiv thaiv nyhuv
Cov nyhuv ntawm argon tiv thaiv tuaj yeem raug txiav txim raws li xim ntawm cov vuam. Thaum lub sij hawm welding txheej txheem, lub welder tuaj yeem kho cov roj shielding raws li cov xim, kom cov vuam tuaj yeem ua tiav cov kev tiv thaiv zoo dua. Nws cov xim yog nyiaj dawb, golden daj yog qhov zoo tshaj plaws, xiav yog qhov zoo, liab grey yog qhov zoo, grey yog phem thiab grey thiab dub yog qhov phem tshaj.
Kev ceev faj rau kev tiv thaiv argon filling
(1) Thaum lub sij hawm argon arc vuam, huab cua yuav tsum tau nkag mus rau sab nraum qab ntawm lub vuam seam ua ntej, thiab tus nqi ntws yuav tsum tau nce kom tsim nyog. Tom qab huab cua tawm lawm, tus nqi ntws yuav maj mam txo. Thaum lub sij hawm vuam txheej txheem, argon yuav tsum tsis tu ncua sau rau hauv lub raj. Thaum lub vuam raug nres, cov pa roj yuav ncua thiab cov vuam seam yog tiv thaiv tag nrho. Tsis tas li ntawd, kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov tseeb tias vuam tuaj yeem ua tau tsuas yog tom qab cua txias, txwv tsis pub, kev tiv thaiv ntawm argon filling yuav raug cuam tshuam.
(2) Argon ntws yuav tsum tsim nyog. Yog tias tus nqi ntws tsawg dhau, kev tiv thaiv tsis zoo, thiab sab nraub qaum ntawm cov vuam yog yooj yim rau oxidize; Yog tias tus nqi ntws loj dhau lawm, cov eddy tam sim no yuav raug tsim thaum lub sij hawm vuam thiab cov cua yuav raug coj mus rau hauv cov huab cua, thiab cov nyhuv tiv thaiv kuj yuav deteriorate.
(3) Lub qhov hluav taws xob argon yuav tsum tau muab tso rau hauv qhov tsawg li tsawg tau nyob rau hauv qhov chaw kaw, thiab lub qhov tso pa tawm yuav tsum muab tso rau ntawm qhov chaw siab dua hauv qhov chaw kaw. Vim tias argon hnyav dua li huab cua, sau argon los ntawm txoj hauj lwm qis tuaj yeem ua kom yooj yim dua kom muaj zog dua, thiab kev tiv thaiv ntawm argon filling yog zoo dua.
(4) Txhawm rau txo qhov poob ntawm argon roj hauv cov yeeb nkab los ntawm qhov sib txawv ntawm qhov sib txawv, uas yuav cuam tshuam rau kev tiv thaiv kev tiv thaiv thiab nce tus nqi, daim ntawv daim kab xev tuaj yeem muab tso rau hauv qhov sib txawv ntawm qhov vuam ua ntej vuam, tsuas yog qhov ntev rau welder pib arc vuam.
Hauv kev ua haujlwm tiag tiag, txoj kev tiv thaiv rau sab nraub qaum ntawm cov vuam yuav tsum tau hloov pauv raws li cov yam ntxwv xws li vuam engineering kom muaj nuj nqis, cov yeeb nkab tshwj xeeb, cov txheej txheem yuav tsum tau ua, thiab kev ua haujlwm ntawm kev ua haujlwm kom ntseeg tau tias vuam zoo.
