Cov cuab yeej tswj hluav taws xob hluav taws xob txhawb cov khoom siv Vuam Zoo

Nyob rau hauv daim teb ntawm kev muaj khoom stainless hlau vuam, nyob rau hauv thiaj li yuav tau txais cov khoom zoo weld zoo. Ib qho Argon arc vuam (tsov) yuav raug siv. Thaum cov txheej txheem cia li welded, raws li lub vuam ceev nce, tus arc yuav raug cab, thiab nrawm dua ntawm kev nkag, uas yuav cuam tshuam rau kev vuam zoo.

Cov cuab yeej tswj hluav taws xob tswj tau tsim los ntawm hangao muaj hluav taws xob ruaj khov, lub arc yuav tsis viav vias rov qab los yog sab xis, thiab teeb meem nrog undercutting thiab 'humping ' yuav tsis tshwm sim. Yog li nws tau txhim kho ntau ntau lawm thaum ua kom zoo, thiab kev txhim kho ceev ntawm 20-30% tau txheeb xyuas hauv kev tsim khoom tiag tiag. Qhov ntau ntawm cov hluav taws xob hluav taws xob tuaj yeem hloov kho kom haum rau cov vuam sib txawv thiab nrawm.

Raws li muaj nyob hauv daim duab 1, muaj cov teeb meem undercut ntawm ob sab thiab sab hauv ntawm weld, thiab muaj ib tug 'hump ' teeb meem sab hauv thiab sab nraum Weld. Tshwj xeeb tshaj yog rau cov lag luam welded, thaum cov kav dej huv si, thaum lub undercut teeb meem tsis yog, nws yuav ua rau muaj cov kua thiab corrode cov yeeb nkab steel. Nws tseem ua rau muaj kev ntxhov siab corrosion. Yog li ntawd, nyob rau tom teb ntawm muaj cov khoom lag luam welded, nyob rau hauv thiaj li yuav tau txais cov khoom siv zoo, nws yog qhov tsim nyog los txo cov vuam relding ceev thiab xyuas kom meej qhov vuam zoo.

Txhawm rau kom daws tau cov teeb meem no, peb lub tuam txhab tau tsim lub arc vuam stabilizer, sab xis, qhov teeb meem ntawm undercut thiab 'hump ' yuav tsis tshwm sim (raws li qhia hauv daim duab 2). Nws tsis tsuas yog txhim kho kev ua tau zoo tab sis tseem tuaj yeem lav tau zoo. Qhov nce nrawm ntawm 20-30% tau txheeb xyuas hauv kev tsim khoom tiag tiag. Hauv kev ua haujlwm tiag, lub zog hluav taws xob tuaj yeem hloov kho kom haum rau cov vuam sib txawv thiab nrawm.
