Txoj haujlwm ua haujlwm:
Lub vuam teeb siv lub tshav kub uas tsim los ntawm lub siab tam sim no thiab high voltage ntawm tam sim no los sib sau ua ke ntawm qhov kawg ntawm lub vuam teeb, thiab cov hlau melted nkag mus rau hauv qhov yuav tsum tau welded.Tom qab txias, cov khoom welded yog ruaj khov rau hauv ib qho.
Lub zog ntawm lub teeb yog nyob ntawm lub zog ntawm lub vuam thiab cov khoom siv vuam.
Vuam torch welding nyhuv tsim nyog, vuam kev ruaj ntseg, ceev ceev.
Lub vuam teeb muaj kev txhim khu kev qha, kev saib xyuas yooj yim thiab kev hloov kho yooj yim.
Vuam phom tsis siv hluav taws xob, txuag cov hlau, cov cuab yeej siv nyiaj tsawg thiab lwm yam zoo.
Kev siv lub teeb welding:
Thaum peb xav welding, peb yuav tsum xub xaiv tus qauv tsim nyog thiab sib txawv caliber vuam nozzle raws li qhov loj, thickness thiab thermal conductivity ntawm txawv welds.Kev khiav hauj lwm, thawj zaug unscrew lub acetylene hloov, thiab ces me ntsis unscrew lub oxygen mus, lit acetylene thaiv, ces cov nplaim taws kub tsis siab, lub nozzle nthuav tawm ob txheej ntawm cov nplaim dawb, ntxiv rau, vim acetylene ntau dhau combustion tsis tiav, feem ntau cov pa luam yeeb dub, lub teeb me ntsis ua ntej lwm cov txiaj ntsig ntawm oxygen yog txo cov pa luam yeeb dub.Txhawm rau vuam, kho cov pa oxygen hloov, kom cov pa oxygen thiab acetylene gas tsim nyog, txaus combustion, kub kub.Thaum welding, qhov sib koom ua ke ntawm cov welding yog thawj zaug kub hnyiab mus rau qhov kub ntawm cov xim liab, thiab tom qab ntawd lub vuam pas nrig yog kub hnyiab ntawm qhov vuam thiab ntim rau hauv qhov sib koom ua ke.Tom qab melting ua ke, cov nplaim hluav taws oxyacetylene tuaj yeem raug tshem tawm, thiab cov vuam ua tiav los ntawm kev txias.
Kev xaiv ntawm electrode:
Txawm hais tias vuam los yog kho, nws yog ib qho tsim nyog yuav tau xaiv cov electrode uas tsim nyog raws li cov hlau muab tub lim.Lub zog thiab kev ua tau zoo ntawm kev sib koom tes tsis yog tsuas yog cuam tshuam nrog cov txheej txheem vuam, tab sis kuj ncaj qha ntsig txog cov khoom siv ntawm cov electrode peb siv.
Feem ntau hais lus, lub melting point ntawm vuam pas nrig yuav tsum tsis txhob siab tshaj qhov melting point ntawm vuam qhov chaw, txwv tsis pub nws tsis zoo rau tus tswv lub vuam hlau pas dej ua ke nyob rau hauv lub vuam txheej txheem, yog li ntawd lub vuam molding deteriorates.
