Vuam hlau tas sijhawm?

Tsis zoo li cov khoom lwj uas muaj hnub xaus, vuam hlau tsis muaj qhov txhais "tas sij hawm" hauv kev txiav txim zoo. Txawm li cas los xij, nws txoj kev ua tsis taus dhau sijhawm vim ib puag ncig kev sib kis, cia ib qho kev puas tsuaj, los ua nws tsis siv tau los yog vuam. Nkag siab txog qhov cuam tshuam uas cuam tshuam vuam hlau ntev thiab yuav ntsuas kev ntsuas nws tus mob yog qhov tseem ceeb rau kev zam WELD swb.
VIM LI CAS VUAM HLAU DEEM (Txawm tias tsis muaj hnub tas sij hawm)
Vuam hlau lub peev xwm los tsim cov ntaub ntawv huv, huv yog nyob ntawm nws cov tshuaj lom neeg muaj pes tsawg leeg thiab kev ncaj ncees ntawm lub cev. Sijhawm dhau sijhawm, ntau yam tuaj yeem sib txug cov khoom no:
• Ua noo thiab cov av noo: noo noo yog tus yeeb ncuab loj tshaj plaws ntawm feem ntau vuam hlau. Khoom siv hlau tais (zoo li ER70s-}} {{kua txob rau ntawm weld pas dej npuas uas tsis muaj zog ntawm cov pob qij txha. Flux - Cov xov hlau cored yog txawm ntau dua cov hluav taws xob muaj zog: lawv sab hauv flux nqus noo noo, ua rau hydrogen - Qhov ua rau muaj kev tawg hauv Weld. Qhov no yog kev pheej hmoo tshwj xeeb rau lub siab-zog steel vuam, qhov chaw dej hiav txwv twg tuaj yeem ua rau cov ntaub ntawv loj.
• Corrosion: Stainless hlau thiab Aluminium cov xov hlau tiv taus xeb, tab sis lawv tsis tau txhaj tshuaj tiv thaiv mob corrosion. Stainless hlau hlau tuaj yeem txhim kho Chromium depletion yog tias raug rau ntsev lossis tshuaj lom neeg, txo lawv cov corrosion tsis kam. Aluminium cov xov hlau yuav ua cov txheej tuab, tawv oxide tawv, uas cuam tshuam rau Arc ruaj khov thiab ua rau fusion fusion thaum lub sij hawm vuam.
• Kev puas tsuaj ntawm lub cev: Hlau Spools khaws tsis raug cai tuaj yeem ua rau ntxhov siab, kinked, lossis khoov, ua rau tsis sib xws los ntawm kev sib tw phom. Qhov no ua rau muaj kev nkag siab, tsis xwm yeem, lossis txawm xaim jams - Cov teeb meem uas puas muaj kev puas tsuaj weld zoo. Cov xov hlau zoo (0.023-nti) yog nquag nquag rau kev puas tsuaj, raws li lawv cov kab uas hniav yooj yim.
• Flux Decavation: Flux - cored xov hlau cia siab rau kev tiv thaiv thiab tu. Sij hawm dhau mus, flux tuaj yeem nqus roj, plua plav, lossis noo noo, poob nws lub peev xwm tiv thaiv lub pas dej weld. Flux qub kuj tseem tuaj yeem ua rau tawv ncauj lossis pob txha, ua rau kev tsis sib xws arc kev ua tau zoo thiab kev swb.
Ntev npaum li cas cov hlau ntev ntev?
Nrog rau kev cia khoom zoo, feem ntau vuam hlau nyob usable rau 2-5 xyoos, txawm qhov no los ntawm hom:
• Cov hlau ntim steel: thaum khaws cia hauv cov thawv qhuav, kaw (deb ntawm cov hlau noo thiab av nkos Lawv yooj yim muaj pes tsawg leeg (tsis muaj flux) ua rau lawv muaj ntau dua, tab sis xeb nplua yog ib qho qauv meej ntawm kev ua tsis raws kev ua kom pom tseeb.
• Cov hlau tsis muaj hlau hlau: stainless hlau cov ntaub ntawv chromium slows corrosion, tso cai xaim li er308 mus rau lub sijhawm dhau los ntawm kev tswj hwm. Txawm li cas los xij, raug rau ntsev cua (piv txwv li, hauv cov ntug dej hiav txwv kev cob qhia) tuaj yeem luv qhov no rau 2-3 xyoos.
• Aluminium xov hlau: Aluminium xov hlau muaj lub sijhawm luv luv- feem ntau 2-3 xyoos {3} {{} {} {{} {{} {{} {{} {{} {{} {{} {} {{} {} Vim lawv txoj kev nyiam ua cov kua oxide. Txawm nyob hauv ntim kaw, nyias nyias cov yeeb yaj kiab nyias muaj peev xwm tshem tawm lub sijhawm, txawm hais tias nws tuaj yeem muab tshem tawm nrog tu kom zoo ua ntej siv.
• Flux - Cored xov hlau: Cov no muaj lub neej luv tshaj plaws, feem ntau 1-3 xyoos. Lawv cov flux tau muaj kev nqus tau tias, yog li txawm tias muaj kev noo noo me me raug (piv txwv li khaws cia nyob ze ntawm cov av noo) tuaj yeem siv lawv cov khoom siv cuav tom qab 1-2 xyoos.
Cov neeg tsim khoom feem ntau pom zoo siv flux - cored hlau tsis pub dhau 12-18 lub hlis ntawm kev yuav khoom zoo, tshwj xeeb rau cov ntawv thov.
Qhia koj cov hlau vuam muaj "tas sijhawm" (thiab yuav tsum tau hloov)
Txawm hais tias xaim yog nyob hauv nws lub neej ib txwm, saib cov chij liab uas qhia txog kev ua haujlwm:
• xeb lossis oxidation: ib qho tsis muaj xeb ntawm cov xov hlau, lossis npub, ua rau cov hlau tsis txaus ntseeg. Quav xau cov dej paug cov weld, thaum tuab txhuas oxide txwv tsis pub zoo melting.
• Ua kom ya raws noo: flux {- cored xov hlau uas xav tias tsis muaj zog (ib qho cim ntawm xeb (ib qho cim ntawm xeb), yuav tsum muab pov tseg. Ya raws hauv flux ua rau hydrogen nrib pleb - qhov teeb meem loj hauv cov qauv vuam.
• Tsis zoo Arc Stability: Yog tias cov arc setters, pops, lossis yuav tsis tswj hwm lub hlawv khov kho, cov hlau yuav degraded. Flux lossis oxide txheej cuam tshuam rau hluav taws xob, ua rau tsis muaj kev ua tau zoo.
• Kev pub mis tsis xwm yeem: Tangled, kinked, los yog bent xaim txau tsis sib xws, ua rau lub ntsej muag thiab tsis sib xws Weld hlaws dai. Qhov no yog qhov teeb meem tshuab, tsis yog tshuaj, tab sis nws tseem ua rau cov qog siv tsis tau.
• Poros thiab Porosity ntau dhau: Welds nrog cov nplaim hluavtaws lossis tuab {{1} {1} Tshem tawm slag feem ntau qhia tias cov xaim hluav taws xob tsis zoo. Cov Welds tsis muaj lub zog thiab yuav tsum rov ua dua tshiab nrog cov hlau tshiab.
Yuav Ua Li Cas Txuas Vuam Hlau Hlau Nqa
Kev cia kom raug yog txoj kev zoo tshaj plaws los tiv thaiv kev ua haujlwm thaum ntxov:
• Tswj ib qho chaw ib puag ncig: khw cov xov hlau hauv thaj chaw qhuav nrog av noo qis dua 50%. Siv Dehumidifier hauv kev cob qhia, thiab zam kev khaws cov spool nyob ze cov khoom siv dej (piv txwv li, lub qhov rais, qhov rai nrog hws).
• Ntaus cov xov hlau tsis siv cov xaim hluav taws xob hauv lawv cov khoom ntim qub, lossis hloov chaw qhib cov khoom ntim nrog cov khoom noj kom haum rau cov dej noo.
• Zam kev puas tsuaj ntawm lub cev: Khw Spools Upright (tsis yog pawg) los tiv thaiv Tangling, thiab lis kom ua tib zoo kom tsis txhob kinking. Siv cov xaim hluav taws xob sawv ntsug kom cov kab mob spool ruaj khov thaum siv sijhawm.
• Sau npe thiab tig cov khoom Tshuag: Kos tawm cov lus nrog cov hnub yuav khoom thiab siv cov xaim qub ua ntej. Qhov no tiv thaiv cov xaim los ntawm kev zaum tsis siv rau xyoo, txo qis kev pheej hmoo ntawm kev ua phem.
• Bak blux - Cov xov hlau cored (yog tias xav tau me ntsis cov xaim hluav taws xob {}}}
Xaus: tsis muaj hnub tas sij hawm, tab sis yog "zoo tshaj plaws los ntawm" rau kev ua tau zoo
Vuam hlau tsis tas sij hawm los ua qhov txaus ntshai, tab sis nws poob tau zoo rau lub sijhawm noo, corrosion, lossis kev puas tsuaj rau lub cev. Ib qho 10 {- xyoo {}} Tus kav dej khib nyiab tsis zoo li los tsim cov thawv ntim khoom zoo nkauj, thaum muaj 3-xyoo-laus hlau khaws cia hauv cov thawv ntim khoom yuav ua haujlwm tau zoo kawg nkaus.
Txhawm rau zam cov teeb meem, tshuaj ntsuam cov xov hlau ua ntej siv: oxidation, lossis kev puas tsuaj, thiab sim ua kom ntseeg tau tias arc stability thiab nkag mus. Thaum tsis ntseeg, hloov cov hlau qub - Tshwj xeeb yog rau cov qauv steel lossis cov khoom siv nyab xeeb, qhov twg weld ua tsis tau muaj kev cuam tshuam loj heev.
Los ntawm khaws cov kav hlau kom zoo thiab hloov lawv thaum cov cim qhia txog kev tsis txaus siab, koj yuav ua kom muaj xwm txheej zoo nkauj, muaj zog}} Tsis muaj teeb meem lub hnub nyoog.
