Cov hom kev thaiv cov roj
Feem ntau siv cov ntaub thaiv npog rau cov vuam siv laser feem ntau suav nrog N2, Ar, Nws, thiab lawv cov khoom siv lub cev thiab tshuaj muaj qhov sib txawv, thiab yog li ntawd lawv cov teebmeem ntawm lub weld kuj tseem sib txawv.
1. Nitrogen N2
Lub zog ionization ntawm N2 yog muaj nqees, siab dua li ntawm Ar thiab qis dua qhov ntawm Nws. Raws li qhov kev txiav txim ntawm laser, ionization degree yog qhov nruab nrab, uas tuaj yeem txo qhov tsim ntawm plasma huab thiab nce qhov kev siv txiaj ntsig ntawm laser. Nitrogen tuaj yeem tso tshuaj lom nrog aluminium alloy thiab carbon steel ntawm qhov kub kom tsim tau cov nitrides, uas yuav ua rau muaj qhov nkig ntawm qhov txuas, txo qhov tawv, thiab yuav muaj qhov cuam tshuam ntau dua rau cov khoom siv kho tshuab ntawm qhov sib txuas weld sib txuas. Yog li, nws tsis pom zoo kom siv cov tshuaj tiv thaiv nitrogen. Aluminium alloy thiab carbon hlau welds muaj kev tiv thaiv.
Lub nitride tsim tawm los ntawm cov tshuaj lom neeg cov tshuaj tiv thaiv ntawm nitrogen thiab stainless hlau tuaj yeem ua kom lub zog ntawm qhov sib txuas ntawm qhov txuas, uas yuav pab txhim kho cov neeg kho tshuab cov khoom sib txuas. Yog li no, nitrogen tuaj yeem siv los ua cov ntaub thaiv cov roj thaum vuam hlau stainless.
2. Argon Ar
Lub zog ionization ntawm Ar yog qhov qis heev, thiab cov ionization degree yog qhov siab nyob rau hauv qhov kev txiav txim ntawm laser, uas tsis yog qhov zoo rau kev tswj hwm qhov tsim ntawm cov ntshav plasma, thiab yuav muaj qee yam kev cuam tshuam rau kev siv laser zoo. Txawm li cas los xij, qhov kev ua ntawm Ar muaj tsawg heev thiab nws yog qhov nyuaj rau kev sib tham nrog kev siv hlau. Tus nqi ntawm Ar tsis yog siab. Tsis tas li ntawd, qhov ceev ntawm Ar yog qhov siab dua, uas tau txais txiaj ntsig kom tog mus rau sab saum toj ntawm lub pas dej weld, thiab tuaj yeem tiv thaiv zoo dua cov pas dej weld, yog li nws tuaj yeem siv cov pa hluav taws xob tiv thaiv.
3. Helium Nws
Nws muaj lub zog ionization ntau tshaj plaws, thiab cov ionization degree yog tsawg heev nyob rau hauv qhov kev txiav txim ntawm laser, uas tuaj yeem tswj tau qhov tsim los ntawm cov huab. Laser tuaj yeem ua rau ntawm cov hlau zoo heev, thiab Nws muaj qhov ua haujlwm qis heev thiab tsis tshua muaj tshuaj lom neeg nrog cov hlau. Nws yog qhov zoo rau kev tiv thaiv roj rau vuam seams, tab sis tus nqi Nws siab dhau heev. Feem ntau, cov khoom lag luam loj yuav tsis siv cov roj no. Nws feem ntau siv rau kev tshawb fawb los yog cov khoom lag luam nrog cov khoom muaj nqi siab heev.
Tshuab txoj kev tiv thaiv roj.
Daim duab 1
Tam sim no, muaj ob txoj kev tseem ceeb los tshuab cov roj thaiv npog: ib qho yog los tshuab cov roj ntawm daim hlau thaiv rau ntawm sab phom, uas yog muaj nyob hauv Daim Duab 1; lwm qhov yog cov roj nplaum coaxial, raws li qhia hauv daim duab 2.
Daim duab 2
Yuav ua li cas xaiv ob lub ntsej muag tshuab txheej txheem yog ib qho kev xav ntawm ntau yam. Feem ntau, nws raug nquahu kom siv sab tshuab tshuab txoj kev tiv thaiv roj.
Cov hauv paus ntsiab lus rau kev xaiv txoj kev tshuab cov pa roj thaiv kev tiv thaiv
Ua ntej tshaj plaws, nws yuav tsum ua kom pom tseeb tias qhov thiaj li hu ua "oxidation" ntawm lub weld tsuas yog ib qho muaj npe xwb. Raws li txoj kev xav, nws yog hais txog kev siv tshuaj lom neeg ntawm lub weld nrog cov phom sij hauv cov huab cua, uas ua rau cov khoom tsis sib haum ntawm qhov txuas ntawm lub weld. Nws yog ib txwm muaj tias cov hlau hlau txuas yog nyob ntawm qee qhov kub. Nws reacts tshuaj nrog oxygen, nitrogen, hydrogen, thiab lwm yam hauv huab cua.
Txhawm rau tiv thaiv lub weld los ua" oxidized" yog kom txo lossis zam qhov sib tiv tauj ntawm cov khoom tsis zoo no nrog lub hlau cuaj hlau hauv qhov kub. Lub tshav kub kub hauv lub xeev no tsis yog tsuas yog hlau hlau nyob hauv pas dej molten, tab sis txij li lub sijhawm los ntawm cov hlau weld yog yaj rau hlau molten. Lub pas dej ua ke hlau solidifies thiab nws cov kub poob qis dua ib qho kub thaum lub sijhawm tag nrho lub sijhawm.
Piv txwv
Piv txwv li, titanium alloy welding tuaj yeem nqus tau hydrogen thaum kub siab tshaj 300 ° C, nqus cov pa oxygen thaum kub siab tshaj 450 ° C, thiab nqus cov pa nitrogen thaum kub siab tshaj 600 ° C, yog li cov titanium alloy weld yog solidified thiab qhov kub thiab txias txo mus rau 300 ° C Cov kev tiv thaiv zoo tiv thaiv yuav tsum nyob hauv cov theem hauv qab no, txwv tsis pub nws yuav" oxidized" ;.
Los ntawm cov lus piav qhia saum toj no, nws tsis yog qhov nyuaj kom nkag siab tias lub tshuab thaiv cov pa tawm tsis yog tsuas yog yuav tsum tiv thaiv cov pas dej weld kom raws sijhawm, tab sis kuj tseem xav tau los tiv thaiv thaj chaw tsuas yog qhov chaw tau txais welded. Yog li ntawd, lub laj kab thaiv kev qhia ntawm daim duab 1 feem ntau siv. Tshuab thaiv kev thaiv cov pa roj, vim tias hom kev tiv thaiv no muaj qhov kev tiv thaiv dav dua li cov txheej txheem tiv thaiv coaxial hauv daim duab 2, tshwj xeeb tshaj yog rau thaj chaw uas tus hlau tau nyuam qhuav tau sib tw.
Sideshaft side blowing Rau kev siv engineering, tsis yog txhua yam khoom siv tuaj yeem siv cov ntug kev ua lag luam sab tshuab tshuab roj. Rau qee yam khoom tshwj xeeb, tsuas yog cov coaxial tiv thaiv roj tuaj yeem siv, uas yuav tsum tau nqa tawm los ntawm cov khoom qauv thiab daim ntawv sib koom ua ke. Xaiv hom kev xaiv.
Xaiv kev qhia tshwj xeeb ntawm cov roj thaiv cov ntsej muag roj
Ncaj weld
Lub weld duab ntawm cov khoom yog ncaj, thiab daim ntawv sib koom tes tuaj yeem yog pob qij pob txha, ceg tawv sib koom tes, sab hauv lub kaum pob ntsej muag lossis sib tshooj welded sib koom tes. Hom khoom no adopts sab-phuam puab los tshuab txoj kev tiv thaiv roj qhia hauv daim duab 1. Zoo dua.
Dav hlau raug kaw duab weld
Lub weld duab ntawm cov khoom yog cov qauv kaw xws li lub voj voos tiaj, tiaj tus polygon, tiaj polyline, thiab lwm yam. Daim ntawv sib koom ua ke tuaj yeem yog pob qij txha, ceg tawv sib txuas, sib koom tes sib dhos, thiab lwm yam. yog muaj nyob hauv Daim Duab 2 Coaxial shielding roj txujci zoo dua.
Kev xaiv cov roj av los tiv thaiv ncaj qha cuam tshuam rau qhov zoo, ua haujlwm thiab tus nqi ntawm kev ua haujlwm vuam. Txawm li cas los xij, vim muaj ntau yam khoom siv vuam siv, hauv cov txheej txheem welding tiag tiag, kev xaiv ntawm vuam roj kuj tseem nyuab dua. Nws yog qhov tsim nyog los ua kom nkag siab txog cov khoom siv vuam, vuam txheej txheem, thiab vuam txoj hauj lwm. Raws li qhov yuav tsum tau muaj cov vuam siv, cov vuam kev tsim nyog vuam ntau tuaj yeem xaiv los ntawm kev xeem vuam kom ua tiav cov vuam zoo dua.
