Tsis ntev lossis tom qab, nws dhau los ua qhov tsim nyog txuas rau ob ntu hlau los ntawm kev siv vuam, yog nws yog qhov cuab yeej vaj, lossis kev teeb tsa ntawm ib qho qauv hlau. Nws yuav zoo li tias tsuas muaj ib txoj hauv kev tawm xwb - txhawm rau hu rau tus kws tsim tawm welder. Tab sis, muaj muas lub vuam siv tshuab thiab cov cuab yeej tsim nyog, koj tuaj yeem kawm kos duab no koj tus kheej. Kev xyaum yog tus kws qhia ntawv zoo tshaj plaws los qhia.
Nws yog qhov tsim nyog
Lub tshuab vuam tshuab, cov npog ntsej muag, lub tsho, cov ris thiab cov hnab looj tes ua los ntawm cov tawv tuab thiab tarpaulin
Cov Lus Qhia
Kauj ruam 1
Thaum thawj theem ntawm kev cob qhia, nws yog qhov yuav tsum tau yuav lub tshuab hluav taws xob vuam nws tus kheej. Rau cov pib tshiab, lub tshuab nrog qhov siab tshaj plaws ntawm 140A thiab ib lub cuab yeej rau kev tswj kom ncaj ntawm vuam tam sim no haum. Ib daim npog tiv thaiv, lub tsho, cov ris thiab cov hnab looj tes ua los ntawm cov tawv tuab thiab ntaub tarpaulin.

Ntawm theem ob, peb ncaj qha mus ua noj. Txhawm rau ua qhov no, koj xav tau electrodes nrog lub cheeb ntawm 2, 5 - 3mm. Clamp "lub ntiaj teb" yog ruaj khov nrog cov haujlwm ua haujlwm, thiab cov electrode yuav tsum muab khi kom ruaj rau tus tuav.
Kauj ruam 3
Ua ntej koj yuav tsum kawm paub yuav ua li cas taws cov electrode. Nqa cov electrode mus rau qhov ntawm ib sab kaum ntawm 60 -70 degrees, thiab ntawm qhov ceev ntawm 5 -10 cm / sec, kos lub electrode tshaj ib feem. Yuav muaj ib lub tawg thiab ib lub hnab ntawm khoob. Tom qab ntawd, ntawm tib lub kaum, kov lub workpiece thiab tam sim ntawd nce cov electrode los ntawm 3-5 hli. Arc yuav taws. Coj cov electrode raws lub workpiece yuav tsum tau welded thiab tib lub sijhawm, thaum cov electrode hlawv tawm, tswj qhov sib txawv nruab nrab ntawm cov electrode thiab qhov haujlwm los ntawm peb txog tsib hli. Yog tias cov nplaim hluav taws xob sib txuas lossis lub arc tsis ua haujlwm, lub vuam tam sim no tsawg dhau. Nce nws me ntsis. Nyob rau theem ntawm txoj kev kawm no, nws yog qhov tsim nyog los txhim kho cov kev txawj ntawm kev tswj cov arc nrog qhov sib txawv ntawm 3-5 hli ntawm qhov kawg ntawm qhov hluav taws xob thiab cov khoom ua haujlwm tau txais welded.
Kauj ruam 4
Ntawm cov theem tom ntej, peb kawm yuav ua li cas weld lub hlaws. Txhawm rau ua qhov no, koj yuav tsum tau taws lub arc, thiab maj mam txav cov electrode raws tus hlau txuas. Hauv qhov no, nws yog qhov yuav tsum tau ua ntawm kev ua si oscillatory nrog lub zog ntawm 2 - 3 hli, zoo li yog "raking" tus hlau molten mus rau arc crater. Yog li, tus txhim khu kev qha weld yuav tsum tau tsim nrog lub teeb, tsis tshua pom qhov tsis pom ntawm weld hlau.
Kauj ruam 5
Ntawm theem kawg ntawm kev cob qhia, lub pob npog ntawm cov npoo npog, tsim thaum lub sijhawm sib txuas ntawm cov flux, uas npog cov electrode, raug tshem tawm. Tom qab cov npoo tau txias, nws tau tev nrog rab rauj, lub pob slag tawm thiab lub tshuab hluav taws xob vuam qhib, ci nrog hlau ntshiab.
Kauj Ruam 6
Tom qab koj kawm paub yuav ua li cas thiaj ua lub laub, koj tuaj yeem pib ua lag luam siv hluav taws xob vuam, ua noj ua ntu ntawm qhov tsim nyog thiab khoom siv.
