Aluminium tau tso tseg tsis suav tias yog cov khoom siv tsis tshua muaj thiab tau nkag mus rau peb lub neej, dhau los ua qhov tsim nyog xav tau. Cov ntawv thov rau txhuas txuas ntxiv nthuav. Peb tshuav nuj nqi tsim lub teeb, tab sis, txawm tias qhov no, lub tsev ruaj khov rau cov khoom siv no. Thaum pib txuas cov hlau txuas, tus neeg tsim khoom siv yuav tsum muaj kom paub txog nws cov nta thiab vuam siv tshuab.

Cov Lus Qhia
Kauj ruam 1
Npaj qhov chaw rau vuam. Profile npoo thiab tshem tawm cov oxides. Degrease thiab tshem tawm qhov chaw tsis huv uas siv cov kuab tshuaj organic. Dawb plig, PC-1, PC-2 solvent lossis technical acetone yog haum. Koj tseem tuaj yeem kho saum npoo rau hauv da dej alkaline. Ua li no, npaj ib qho kev daws teeb meem qhov twg 1 liter dej muaj 30 g ntawm dej iav thiab 50 g ntawm technical trisodium phosphate thiab dej qab zib tshauv.
Kauj ruam 2
Txheej txheem rau saum npoo rau 5 feeb ntawm 70 ° C. Yog li, cov qub oxide zaj duab xis uas muaj adsorbed ya raws yuav tshem tawm cov seem. Cov oxide zaj duab xis kuj tuaj yeem muab tshem tawm los ntawm scraping, tom qab uas tus ntug yuav tsum tau degreased dua nrog cov kuab tshuaj. Tom qab stripping, seem tuaj yeem khaws cia rau 2-3 teev ua ntej welding.

Ua ntej tiv tauj seam thiab chaw vuam, ntxiv rau ntxuav cov npoo sib tshooj nrog cov hlau txhuam sib txuas. Yog hais tias lub tuab ntawm cov nplooj ntawv yuav tsum koom nrog yog siab dua 0.3 cm, tshem tawm cov clad txheej los ntawm kev sib sib zog nqus etching, uas yuav tiv thaiv tau qhov tsim ntawm qhov tsis muaj fusion. Nqa tawm etching hauv da dej ntawm kev daws teeb meem ntawm sodium hydroxide (50 g ib liter dej) ntawm qhov kub ntawm 70 ° C rau 1-2 feeb. Txiav qhov kawg ntawm seem, piv txwv, ntawm lub tshuab siv hlau txiav.

Thaum welding allolo alloys los ntawm fusion, nws raug nquahu kom ua cov pob qij txha txuas. Txhawm rau tshem tawm oxide suav hauv cov nqaws dej, siv cov ntxhua khaub ncaws nrog ib tus zawj uas lawv yuav raug tshem tawm. Hauv kev sib cav argon-arc vuam, oxide suav nrog yuav txo los ntawm kev thov fluxes rau qhov xaus. Kev sib txuas ntawm cov pob qij txha yog tsim los ntawm kev xaws thiab chaw ruaj khov kho qhov chaw. Qhov feem pua ntawm cov tuab ntawm seem yuav tsum tau welded yuav tsum tsis pub ntau tshaj 1: 2. Taub qab ua ke yog siv rau kev sib tw nyem taub hau vuam.
Kauj ruam 5
Rau roj vuam, nws pom zoo kom siv cov nplaim hluav taws xob ntawm cov O2: C22 sib xyaw. AF-4A flux yog qhov tshwj xeeb yog siv rau hauv daim ntawv ntawm qhov muab tshuaj txhuam lossis tau qhia nrog tus muab tub lim thaum vuam. Rau cov muab tub lim hlau, ib qho txhuas vuam hlau siv, qhov taub uas yog nyob ntawm qhov tuab ntawm cov hlau.
Kauj Ruam 6
Gas-shielded arc vuam yog dav siv los koom nrog txhuas. Argon lossis kev sib xyaw ntawm argon thiab helium yog siv los ua roj. Argon purity yuav tsum yog tsawg kawg 99.9%. Yog tias cov hlau txuas nrog cov electrode uas siv tau, koj tuaj yeem siv cov argon nrog qhov sib ntxiv ntawm O2, tab sis tsis tshaj 5%.
Kauj Ruam 7
Los ntawm txhais tes hluav taws xob arc vuam yog nqa nrog cov xaim npog lossis cov pa roj carbon electrode. Carbon arc vuam yuav tsum tau ua nrog cov hluav taws xob ncaj qha tam sim no. Hauv arc vuam nrog cov xaim hluav taws xob, kev daws teeb meem ntawm dextrin los yog sodium chloride hauv dej ua rau lub binder. Cov txheej txheem yuav siv qhov chaw ntawm tam sim no ncaj qha ntawm rov qab polarity.
Kauj ruam 8
Yog hais tias lub thickness ntawm lub pob tw pob qij txha yog ntau dua 0.4 cm, tsis siv neeg arc vuam siv nrog txheej txheej. Nws yog tsim los ntawm cov hluav taws xob uas siv tau. Lub zog mov yuav tsum tau tam sim no ncaj qha ntawm qhov rov qab polarity. Lub flux yuav tsum nrog txo hluav taws xob conductivity, piv txwv li, ceramic. Nws yog sib xyaw nrog cov kua tov ntawm carboxymethylcellulose, txhuam los ntawm sab cib thiab calcined rau 6 teev ntawm qhov kub ntawm 280-320 ° C. Vuam yog nqa tawm nrog electrode cais.
