Dab tsi yog Oxy-Acetylene Hardfacing Method

Taw qhia ntawm Oxy-Acetylene vuam

Muaj ntau ntau hom vuam txheej txheem rau fusing ua ke hlau. Los ntawm flux-cored welding mus rau GTAW / TIG vuam, mus rau SMAW vuam, mus rau GMAW / MIG vuam, txhua txoj kev vuam ua haujlwm rau lub hom phiaj tshwj xeeb nyob ntawm qhov xwm txheej thiab hom khoom siv welded.

Lwm hom vuam yog oxy-acetylene vuam. Paub tias yog oxy-fuel welding, oxy-acetylene welding yog txheej txheem uas tso siab rau kev sib txuas ntawm cov pa thiab cov roj roj, feem ntau yog acetylene. Tej zaum koj feem ntau hnov ​​​​cov vuam hom hu ua "gas welding."

Feem ntau, roj welding yog siv rau welding nyias hlau seem. Cov neeg tuaj yeem siv oxy-acetylene welding rau cua sov ua haujlwm, xws li tso cov bolts khov thiab ceev thiab cua sov cov khoom hnyav rau kev khoov thiab muag muag muag.

Oxy-Acetylene Vuam Ua Haujlwm Li Cas?

Oxy-acetylene welding siv cov hluav taws kub kub, kub kub uas yog tsim los ntawm kev hlawv roj (feem ntau acetylene) tov nrog cov pa ntshiab. Cov khoom siv hauv paus yog yaj nrog cov pas nrig siv cov nplaim hluav taws los ntawm kev sib xyaw ntawm oxy-roj roj los ntawm qhov kawg ntawm lub vuam teeb.

Cov pa roj carbon monoxide thiab cov pa roj carbon dioxide yog khaws cia rau hauv lub tog raj kheej pressurized steel. Regulators nyob rau hauv lub tog raj kheej txo cov roj siab.

Gas ntws los ntawm cov hoses hloov tau yooj yim, nrog cov welder tswj qhov ntws ntawm lub teeb. Tom qab ntawd lub pas nrig yog melted nrog cov khoom siv hauv paus. Txawm li cas los xij, melting ob daim hlau kuj tseem ua tau yam tsis tas yuav tsum tau muab tub lim.

Dab tsi yog qhov txawv ntawm Oxy-Acetylene Vuam thiab Lwm Yam Vuam?

Qhov sib txawv tseem ceeb ntawm oxy-fuel welding thiab arc vuam hom xws li SMAW, FCAW, GMAW, thiab GTAW yog qhov cua sov. Oxy-roj vuam siv cov nplaim taws ua qhov cua sov, ncav cuag qhov kub txog li 6,000 degrees Fahrenheit.

Arc vuam siv hluav taws xob los ua qhov cua sov, ncav cuag qhov kub li ntawm 10,000 F. Txawm li cas los xij, koj yuav xav tau ceev faj thiab muaj kev nyab xeeb thaum vuam nyob ib ncig ntawm txhua yam kub kub.

Nyob rau hauv thaum ntxov hnub ntawm welding, oxyfuel welding yog siv los weld tuab daim hlau. Tam sim no, nws yuav luag tsuas yog siv rau nyias hlau. Qee cov txheej txheem arc vuam, xws li GTAW, tab tom hloov cov txheej txheem oxy-roj vuam ntawm cov hlau nyias.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
