Ntshav tooj liab yeeb nkab vuam txheej txheem, tsis tsuas yog xaiv txoj kev vuam tsim nyog, tab sis kuj yuav tsum tau them sai sai rau qhov zoo tshaj plaws vuam kub, qhov kub siab dhau los yog qis dhau, yuav muaj qee yam cuam tshuam rau tag nrho cov vuam.
Qhov zoo tshaj plaws kub ntawm vuam tsis yog ib txheej ntawm invariable, thiab qhov kub thiab txias ntawm lub zos lub zos, dej vapor thiab thiaj li nyob rau hauv ib tug tej yam kev sib raug zoo, tom qab cov yam tseem ceeb yog xam, qhov tseem ceeb tshaj plaws yuav tsum xav txog yog qhov kub thiab txias ntawm cov nplaim taws.
Carbide nplaim yog tam sim no siv nyob rau hauv cov nplaim taws ntau dua, nws yog tiag tiag oxygen thiab ethyl gas kev sib nrig sib combustion, tshuaj lom neeg cov tshuaj tiv thaiv, nws yuav siv tau raws li hlau txiav thiab vuam, thiab thov hais tias cov dawb oxide khoom. Thaum siv cov nplaim carbide rau vuam, nyob rau hauv ib txwm muaj xwm txheej, nws raug nquahu kom tswj qhov kub ntawm 2700 degrees nce lossis nqis.
Cov nplaim hluav taws xob nruab nrab tam sim no pib txo qis kev siv cov nplaim taws, uas yog tus cwj pwm los ntawm cov nplaim hluav taws xob uas ncaj qha cuam tshuam nrog kev sib xyaw ua ke, ntws tus nqi thiab nplaim taws txoj kab uas hla hauv cov roj combustion. Cov nplaim nruab nrab tuaj yeem muab faib ua peb txheej, qhov tseem ceeb ntawm cov nplaim taws yog lub khob hliav qab, xim yog xim dawb, cov nplaim sab hauv yog xiav, tag nrho saib, yog lavender rau xiav. Qhov kub ntawm cov nplaim nruab nrab nyob rau hauv ib txwm muaj, nws raug nquahu kom tswj tsawg kawg 3000 degrees saum toj no, qhov siab tshaj plaws tsis siab tshaj 3400 degrees.
Oxidation nplaim taws yuav tsum tau ua haujlwm siab heev, maj mam hloov los ntawm lwm cov nplaim taws, nws yog kev siv cov pa oxygen thiab ethyl block gas rau cov nplaim taws, thiab nruj me ntsis tswj cov roj siab ntawm 0.5Mpa nce thiab nqis, thiab tom qab ntawd qhib lub oxygen valve thiab ethyl block gas valve nyob rau tib lub sij hawm ignition, qhov sib tov piv ntawm ob gases feem ntau yog raws li cov khoom, kev tsim kho yuav tsum tau txiav txim siab, nws yog qhov kub thiab txias tsis yog tshwj xeeb yog tsau los coj tus nqi.
Copper yeeb nkab welding ceev faj
Ua ntej, vuam yog nruj me ntsis txwv tsis pub tungsten electrode thiab hlau los yog tungsten electrode nyob rau hauv kev sib cuag nrog lub pas dej ua ke molten, qhov teeb meem no yog ib tug ntau ntawm builders tsis pom, yog hais tias muaj ib tug 'tungsten' xwm txheej, tooj liab yeeb nkab tej zaum yuav tshwm sim nyob rau hauv ntau qhov sib txawv ntawm cov kab nrib pleb, thiab nyob rau hauv qhov mob hnyav, nws yuav ua rau cov yeeb nkab tooj liab ncaj qha scrapped. Yog tias muaj 'ua si tungsten', nres vuam kom sai li sai tau, tuav thiab txhuam lub raj tooj liab, thiab hloov lub tungsten ncej kom sai li sai tau.
Qhov thib ob, tswj qhov kub thiab txias. Ntawm no tus tswj qhov kub thiab txias yog hais txog qhov kub thiab txias interlayer ntawm cov khaubncaws sab nraud povtseg ntawm cov yeeb nkab tooj liab, nyob rau hauv kev tsim kho, ib zaug tus neeg teb xov tooj pom lub melting yog heev nyuaj, yuav tsum tau nce lub preheating kub, yuav tsum tau nqa tawm dua nyob rau hauv lub tooj liab yeeb nkab preheating, preheating kub. yuav tsum siab tshaj 520 degrees. Vuam nyob rau hauv cov ntaub ntawv ntawm kub tsis tau raws li qhov yuav tsum tau, nws yog ib qho yooj yim rau tshwm sim tsis zoo welding cov tshuaj tiv thaiv, ncaj qha cuam tshuam rau qhov zoo ntawm cov ntshav tooj liab yeeb nkab vuam.
Thib peb, feem ntau tom qab qhov kawg ntawm qhov vuam ntawm qee cov ntsiab lus me me, qhov no kuj yog qhov feem ntau yuav tsis quav ntsej los ntawm tus neeg teb xov tooj, vuam arc tawm, vuam teeb tsis tuaj yeem tawm tam sim lossis nqa, tos me ntsis 5 feeb lossis li ntawd, mus txuas ntxiv siv lub lagging roj kaw kev tiv thaiv kev ua haujlwm los tiv thaiv cov kua nplaum, ntawm cov phom vuam lossis, rau lub raj tooj liab nws tus kheej, yog qhov zoo.
