Nyob rau hauv kev lag luam vuam, qhov twg precision thiab zoo yog qhov tseem ceeb, txhua kauj ruam ntawm cov txheej txheem teeb meem. Ib qho kev coj ua uas yuav zoo li txawv me ntsis rau cov neeg sab nraud tau muab vuam vuam hauv qhov cub. Tab sis qhov no tsis yog kev ua yeeb yam; Nws yog ib ruam tseem ceeb kom ntseeg tau tias kev ua tau zoo thiab kev ntseeg tau ntawm cov pas nrig vuam.
Txhawm rau kom nkag siab yog vim li cas, peb xub yuav tsum rov qab siv cov pas nrig vuam yog qhov muaj kev tiv thaiv noo noo heev. Raws li peb paub, noo noo yog lub koov- yeeb ncuab ntawm cov pas nrig vuam. Txawm nyob ib puag ncig qhuav, muaj ib txwm muaj qee qib av noo nyob saum huab cua. Welding rods, tshwj xeeb tshaj yog tsawg - hydrogen electrodes, muaj lub zog muaj zog los so kom cov dej noo. Thaum lawv nqus dej noo, muaj teeb meem ntawm cov teeb meem tuaj yeem tshwm sim thaum lub sijhawm vuam.
Kev ya ua dej hauv vuam pas nrig tuaj yeem ua rau tsis muaj kev ruaj khov arc. Thaum koj ntaus ib lub arc nrog noo noo -}}}} laden pas nrig, lub arc yuav flicker, lossis txawm tias yuav tsis poob nthav. Qhov no ua rau nws nyuaj heev rau kev tswj hwm vuam khov kho, ua rau muaj kev sib tw ntawm Welds. Ntxiv mus, noo noo tuaj yeem ua rau muaj zog ntxiv. Sib cav hais txog cov tee dej me me ntawm molten hlau uas ya tawm thaum lub sij hawm vuam. Ntau ntau lub ncauj lus tsis yog ua rau lub weld saib messy tab sis kuj nkim cov khoom siv thiab yuav tsum tau tu dua tshiab.
Ntau dua tiag, noo noo hauv vuam pas nrig tuaj yeem ua rau muaj kev puas ntsoog hauv Weld. Porosity yog lub xub ntiag ntawm cov qhov me me lossis voids hauv Weld hlaws. Cov qhov muaj zog tsis muaj zog ntawm cov qauv ntawm Weld, txo nws lub zog thiab lub zog. Rau kev siv vuam Tsawg - hydrogen electrodes tshwj xeeb tshaj yog feem ntau muaj kev pheej hmoo ntawm no. Kev ya raws hauv cov hluav taws xob no tuaj yeem tso hydrogen thaum lub sij hawm vuam, thiab hydrogen {}} Qhov twg tuaj yeem rhuav tshem lub foob pob ua kom tiav.
Qhov no yog qhov twg tso vuam pas nrig hauv qhov cub los ua si. Qhov cub muab ib puag ncig tswj tau nrog qhov kub tshwj xeeb, feem ntau yog li 250℃f rau 82℃rau 427 degree) nyob ntawm seb hom vuam vuam. Cov cua sov los ntawm qhov cub tawm cov dej noo uas cov pas nrig vuam tau nqus. Los ntawm kev tshem cov dej noo, peb tuaj yeem tiv thaiv cov teeb meem uas tau hais los saud.
Lwm qhov laj thawj rau kev siv qhov cub yog los tswj kev ncaj ncees ntawm cov kab hlau vuam. Cov txheej ntawm vuam pas nrig pabcuam pab ntau lub hom phiaj, tiv thaiv weld pas dej hauv pas dej ntawm cov khoom sib xyaw nrog cov khoom siv hluav taws xob. Thaum vuam pas nrig nqus noo noo, txheej tuaj yeem pib tawg. Cov tswj kev kub ntxhov ntawm lub qhov cub pab ua kom cov txheej ua kom zoo nyob rau hauv zoo, kom nws ua haujlwm raws li npaj siab.
Kev Cia Khoom Kom Zoo Tom Qab Ci kuj muaj feem xyuam rau qhov cub. Tom qab noj cov kab hlau vuam tawm ntawm qhov cub, yog tias lawv tsis yuav siv tam sim ntawd, lawv feem ntau khaws cia hauv kev tuav lub qhov cub ntawm qhov ntsuas kub. Qhov no tiv thaiv lawv los ntawm reabsorbing noo noo los ntawm cov huab cua ib puag ncig, khaws cia rau hauv lub xeev qhuav kom txog thaum lawv xav tau vuam.
Txawv ntau hom vuam rods muaj qhov cub sib txawv thiab lub sijhawm yuav tsum tau ua. Piv txwv li, qis {- hydrogen electrodes feem ntau yuav tsum tau ci kub ntau dua rau lub sijhawm ntev dua kom ntseeg tau tias txhua yam dej noo. Ua raws li cov chaw tsim khoom pom zoo rau cov khoom siv ci yog qhov tseem ceeb kom ua tiav cov txiaj ntsig zoo tshaj plaws.
Hauv kev xaus, tso vuam vuam hauv qhov cub yog qhov tseem ceeb heev hauv cov txheej txheem vuam. Nws yog txhua yam hais txog kev tshem tawm cov dej noo, txuag qhov zoo ntawm cov pas nrig txheej, thiab ua kom pom tseeb tias cov pas nrig vuam ua ntawm lawv qhov zoo tshaj plaws. Los ntawm kev coj cov kauj ruam no, cov kab tua tsiaj tuaj yeem txo qis kev pheej hmoo ntawm kev siv vuam tsis xws luag thiab tsim cov khoom muaj zog, txhim khu kev qha.
