Lub welded stainless hlau yeeb nkab yog kev nyab xeeb dua thiab muaj kev ntseeg zoo dua. Tsis muaj ib lub nplhaib sib khi sab hauv, uas yog lub txuas tuag. Nws muaj ntau hom kev siv, ob leeg raug thiab zais cia nruab. Nws yog qhov tsim nyog dua rau cov dej txias thiab lub nruab nrog dej kub. Ib zaug ntsia, nws yog qhov tsis tsim nyog los xav txog kev saib xyuas. Hom kev sib txuas no tau siv rau ntawm cov kav dej tooj liab tau ntau xyoo, thiab tam sim no Lub Tsev Haujlwm Saib Xyuas Kev Tshawb Fawb tau hais txog kev pom zoo rau hom kev sib txuas no rau kev sib txuas ntawm stainless hlau.
(1) Qhov kev txiav txim ntawm tus nqi thiab tus nqi muag tawm ntawm qhov siab rau qis yog: xaj 1> xaj 2> xaj 3.
(2) Cov Lus Taw Qhia 1-2 yog qhov chaw sib dhos ntawm cov khoom siv (cov cuab yeej tshwj xeeb yuav tsum tau qev) kev txhim kho, nrawm thiab yooj yim, haum rau kev teeb tsa rau saum npoo. Thaum txoj haujlwm ntawm cov roj hmab nplhaib ploj, cov txiv ntoo tuaj yeem raug tshem tawm rau kab xwm 1 los hloov nws, thiab cov txiv ntoo rau cov kab txuas 2 yuav tsum tau hloov tom qab pom vim muaj qhov sib txuas tuag. Cov Lus Taw Qhia 3 yog qhov tsim nyog rau kev zais thiab faus ntsa, ntawm chav kawm, nws tseem tuaj yeem ntsia tau rau saum npoo.
(3) Kev qhia luv luv rau kev teeb tsa ntawm thawj daim npav convex hom: cov cuab yeej tshwj xeeb yuav tsum tau nruab, thiab cov txheej txheem ntawm DN15-50 (DN15-20) cov kav dej yuav tsum tau clamped rau sab nraud phab ntsa ntawm cov yeeb nkab nrog tshwj xeeb twj. Lub tes tsho, (DN25-50) txoj kab uas hla yeeb nkab yog ntsia nrog kauj ruam ntiv nplhaib nyob sab hauv phab ntsa sab hauv ntawm cov yeeb nkab nrog lub cuab yeej.
(4) Kev qhia luv luv rau kev teeb tsa ntawm ntu 2 nias hom: cov cuab yeej tshwj xeeb yuav tsum tau nruab, qhov chaw teeb tsa yog DN15-100, cov yeeb nkab tso rau hauv cov yeeb nkab fittings thiab cov yeeb nkab phab ntsa yog clamped rau hauv hexagonal duab nrog tshwj xeeb cov cuab yeej, thiab sab hauv yog ntim. Lub voj voos kuj tau hloov pauv mus rau hauv hexagon.
(5), Sequence 3 vuam hom (ntsawb argon arc vuam hom): qhov sib txawv nruab yog DN15-100, ntxig rau cov yeeb nkab rau hauv cov yeeb nkab haum thaum txhim kho, thiab siv lub tshuab argon arc vuam tshuab los txuas thiab yaj thawj qhov nqes hav rau cov yeeb nkab haum. Lwm cov muag khoom yog koom nrog lub cev loj vuam thiab kev tsim kho yog yooj yim. (Butt argon arc vuam hom) Cov kab kev teeb tsa yog DN125-200. Thaum txhim kho, ua kom haum rau cov chaw nres nkoj ntawm cov yeeb nkab thiab qhov fittings thiab siv lub tshuab argon arc vuam siv rau qhov vuam, tab sis stainless hlau electrodes yog qhov yuav tsum yog ham. Muaj qee qhov nyuaj hauv kev tsim kho.
(6) Cov yeeb nkab faus yuav tsum sim ua kom tau raws li qhov xav tau ntawm tib lub neej xws li lub tsev. Yog li ntawd, cov yeeb nkab tso rau dej yuav tsum nyiam txuas nrog tsis muaj pob qij txha.
Cov kev pab cuam lub neej ntawm cov kav hlau xeb tau tuaj yeem ncav cuag 70-100 xyoo, uas hais txog cov kav hlau ntshiab ntawm cov yeeb yam tsis muaj lwm yam khoom siv xws li cov nplhaib roj hmab. Nyob rau tib lub sijhawm, cov kav xa dej yuav tsum tau txo cov pob qij txha ntau li ntau tau (ib qho sib koom ntxiv txhais tau tias ntau dua qhov muaj kev phom sij), thiab feem ntau ntawm cov tuam tsev uas siv cov kav hlau (cov kav hlau tsis xeb, cov kav dej tooj liab) yog cov sib txuas welded.
