Nyob rau hauv vuam, kev ua yeeb yam ntawm vuam pas ncaj qha cuam tshuam rau qhov zoo ntawm Welds, thiab lawv lub neej txee yog qhov tseem ceeb uas tsis tuaj yeem tsis quav ntsej. Lo lus nug "Dab tsi yog lub txee lub neej ntawm vuam rods?" Tsis muaj ib tug - loj}-}}}}}}} Nkag siab txog cov xwm txheej no yog qhov tseem ceeb rau kom ntseeg tau tias cov pas nrig vuam tseem ua tau zoo thaum siv.
Cawv ntawm Vuam Rod yam ntawm txee lub neej
Ntau hom vuam pas nrig muaj ntau yam muaj pes tsawg leeg thiab cov tsho tiv no, uas ua rau qhov sib txawv ntawm lawv lub txee.
Cellulose -} hom electrodes (xws li 6010 hom electrodes (xws li 6010): Cov hluav taws xob no muaj cov txheej txheem ntawm cellulose. Cellulose yog tus sib luag nyob rau hauv ib txwm muaj tej yam kev txwv thiab tsis yog li rhiab rau noo noo uas yog lwm hom hluav taws xob. Feem ntau, yog khaws cia rau hauv ib qho qhuav thiab zoo - ventilated ib puag ncig, lawv lub txee lub neej tuaj yeem ncav cuag 2 mus rau 3 xyoos. Txawm tias tom qab lub sijhawm no, tsuav yog tsis muaj kev puas tsuaj rau cov txheej txheem (xws li xeb dej hiav txwv), lawv tseem tuaj yeem siv cov tshuaj tiv thaiv ntawm cov tseem ceeb.
Tsawg - hydrogen electrodes (xws li 7018): Cov no yog qhov rhiab heev rau txhua hom vuam pas dej. Lawv cov txheej txheej muaj cov zaub mov uas yooj yim nqus dej noo los ntawm huab cua. Kev nqus dej noo tsis tsuas yog txo cov kev ua tau zoo ntawm cov hluav taws xob thaum lub sijhawm hydrogen, tab sis kuj tseem muaj kev pheej hmoo ntawm hydrogen {}} Qhov kev pheej hmoo ntawm kev tawg hauv Weld. Lub txee lub neej ntawm tsawg - hydrogen electrodes yog qhov luv. Nyob rau hauv cov kev cia siab zoo tshaj plaws (ntim ntim thiab khaws cia rau hauv ib puag ncig qhuav nrog cov neeg muaj txiaj ntsig qis dua 50%), lawv lub neej lub neej feem ntau yog 1 txog 2 xyoos. Thaum lub pob tau qhib, yog tias tsis khaws cia rau hauv qhov cub rod, lawv siv sijhawm ntau heev rau ib lub lim tiam, nyob ntawm cov av noo ntawm ib puag ncig.
Stainless hlau electrodes: cov hluav taws xob no yog tsim los tiv thaiv kev xeb, tab sis lawv cov txheej ci tseem muaj kev ya raws thiab paug. Lawv lub txee lub neej feem ntau yog 2 txog 3 xyoos thaum khaws cia rau hauv ib puag ncig qhuav, huv. Yog tias lawv raug cov roj av corrosive lossis cov av noo ntev ntev, cov txheej yuav ua rau muaj kev cuam tshuam corrosion, cuam tshuam rau kev ua haujlwm ntawm Weld.
Nrum hlau hluav taws xob: Cov hluav taws xob no tsuas yog siv rau kev kho cov khoom cam. Lawv lub txee lub neej yog qhov tseem ceeb, feem ntau 3 txog 5 xyoos nyob rau hauv cov kev cia khoom kom tsim nyog. Txawm li cas los xij, lawv cov txheej tsho yog nquag ua rau brittleness dhau sijhawm, yog li lawv yuav tsum tau kuaj xyuas cov lej sib xyum ua ntej siv.
Lub luag haujlwm ntawm kev cia khoom hauv txee lub neej
Kev Cia Cov Neeg Muaj Teeb Meem yog qhov tseem ceeb rau kev ncua lub txee lub neej ntawm vuam pas. Txawm tias rau vuam pas nrig nrog lub neej ntev ntev lub neej, tsis tsim nyog yuav ua rau ua tsis tiav.
Vaum noo: noo noo yog tus yeeb ncuab loj tshaj plaws ntawm vuam pas nrig. Cov av noo ib puag ncig (txheeb ze cov av noo siab dua 60%) yuav ua rau feem ntau cov hlua vuam kom nqus noo noo. Rau tsawg - hydrogen mroundment, txawm tias muaj kev nqus me me ntawm kev nqus dej noo tuaj yeem ua rau lawv tsis siv tau. Yog li ntawd, cov chaw cia yuav tsum tau nruab nrog cov khoom siv dehumidification los khaws cov av noo qis dua 50%. Yuav tsum tau vuam pas nrig yuav tsum tau muab cia rau hauv av (siv pallets) kom tsis txhob nqus dej noo hauv av.
Qhov kub thiab txias: huab cua sov heev, ob qho tib si siab thiab qis, tuaj yeem cuam tshuam kev ua tau zoo ntawm vuam pas vuam. Kev kub siab tuaj yeem ua rau cov txheej xim rau oxidize lossis decompity lossis decompit, thaum tsawg kub yuav ua rau txheej loj. Qhov kev cia siab zoo tshaj plaws yog nruab nrab ntawm 50℃f thiab 70℃f (10℃thiab 21 degree).
Ntim: Cov kab ntim vuam vuam muag hauv lawv cov khoom ntim khoom uas ntim tau, uas tuaj yeem tiv thaiv noo noo thiab paug. Ib zaug qhib, cov pas nrig tseem tshuav yuav tsum muab khaws cia rau hauv airtight ntim lossis pas nrig ncu. Rau tsawg - hydrogen electrodes, tom qab qhib, lawv yuav tsum tau muab cia rau hauv qhov cub uas tsim nyog (feem ntau 250℃f) kom tiv thaiv rov ua kom haum.
Kev tiv thaiv los ntawm lub cev puas: cov kab xev yuav tsum muab cia rau hauv txoj hauv kev uas zam kev sib tsoo, extrusion, los yog khoov. Kev puas tsuaj ntawm lub cev rau txheej (xws li tawg lossis tev duab) yuav ua rau cov hluav taws xob hluav taws xob tsis tuaj yeem tsim cov roj av ruaj khov thiab muaj kev tiv thaiv zoo nkauj weld zoo.
Yuav ua li cas los txiav txim seb qhov vuam pas nrig tau tshaj nws lub txee lub neej?
Txawm hais tias lub vuam pas nrig yog nyob hauv lub neej theoretical lub neej, nws yuav tau tas lawm vim tsis muaj kev cia siab. Yog li ntawd, nws yog ib qho tsim nyog los kuaj cov pas nrig vuam ua ntej siv.
Kev Ntsuam Xyuas Kev Pom: Saib cov tsos ntawm lub vuam pas nrig. Yog tias cov hlau tseem ceeb yog xeb, tev tau tawg, hmoov, lossis tau pom cov cim ntawm noo noo (xws li tus pas dawb), lub vuam pas nrig yog yuav tas sij hawm. Rau qis - hydrogen electrodes, yog hais tias txheej zoo nkaus li nplaum nplaum lossis muaj qhov tsw tsw, nws qhia tau tias nws tau nqus cov dej noo ntau.
Kuaj vuam: Rau vuam pas nrig uas xav tias yuav tsum tau tas sij hawm tab sis tsis muaj qhov pom tseeb pom tsis meej, vuam vuam tuaj yeem nqa tawm. Thaum kuaj, yog tias muaj teeb meem xws li tsis ruaj khov arc, porosity nyob rau hauv weld hlaws, nws txhais tau hais tias lub vuam pas nrig tau poob ntsej muag thiab yuav tsum tsis txhob siv.
Txoj kev txuas ntxiv rau lub neej txee ntawm Vuam Rods
Kev ntsuas cov kev ntsuas tsim nyog tuaj yeem ua tau zoo rau lub neej ntawm vuam pas vuam.
Kev tswj nruj ntawm qhov chaw cia khoom: Raws li tau hais ua ntej, tswj ib qho kub qhuav, thiab kev huv ib puag ncig yog tus yuam sij. Rau qis - hydrogen cov hluav taws xob, tshwj xeeb mloog yuav tsum tau them rau kev siv pas qwj ncu cia tom qab qhib lub pob.
Ua ntej -} hauv, ua ntej {1} Tshaj tawm cov kab hlau, npaj lawv kom tau txais cov laus ua ntej. Qhov no tuaj yeem zam qee cov kab hlau vuam tau khaws cia ntev thiab ntev tshaj lawv lub txee lub neej.
Kev tuav kom tsim nyog: thaum noj thiab tso cov kab vuam vuam, kov lawv nrog kev saib xyuas kom tsis txhob ua kom muaj kev puas tsuaj. Tsis txhob kov cov txheej nrog cov roj pleev nrog cov hlua roj, raws li cov roj stains tuaj yeem paug cov electrode thiab cuam tshuam rau weld zoo.
Rov -}} {1} {{} Cov khoom siv hydrogen ntxiv, feem ntau yuav tsis muaj qhov cub ua haujlwm (feem ntau yog cov khoom lag luam hydrogen) Txawm li cas los xij, rov ua dua rov qab -}}}}}}}}}}}}}}} }inging tuaj yeem txo cov kev ua tau zoo ntawm cov txheej txheem ntawm txheej, yog li hom qauv no yuav tsum tsis txhob siv ntau dhau.
Tag
Lub txee lub neej ntawm vuam rods sib txawv raws li hom thiab chaw khaws khoom. Cellulose - hom thiab stainless hlau electrodes muaj lub neej luv (1 txog 2 xyoos nyob rau hauv unpetenity ntim) vim lawv rhiab heev rau noo noo. Txhawm rau kom ntseeg tau tias cov pas nrig vuam nyob hauv lawv lub neej pabcuam, nws yog ib qho yuav tsum tsis txhob saib xyuas ib puag ncig thiab tsis siv pas nrig ncu rau cov khoom siv hydrogen tsawg. Los ntawm kev ua li ntawd, peb tuaj yeem ua kom zoo tshaj plaws ntawm vuam pas, kom cov khoom siv tau zoo, thiab ua kom tsis muaj cov khoom siv ua haujlwm tsis txaus thiab ua haujlwm los ntawm kev siv vuam welding.
