Ntawm Jiangsu XuRui Hlau Group Co., Ltd., ib qho ntawm cov lus nug uas peb tau hnov los ntawm pab pawg fabrication yog: "Inconel puas tuaj yeem tau welded zoo li stainless hlau?"
Cov lus teb luv luv yog yog -Inconel tuaj yeem welded, tab sis hauv kev ua haujlwm tiag tiag nws tsis raug kho zoo ib yam li cov hlau tsis zoo tib yam. Cov khoom siv coj txawv txawv nyob rau hauv tshav kub, thiab cov txheej txheem vuam xav tau kev tswj nruj dua kom tsis txhob muaj teeb meem kev ua haujlwm.
1. Vim li cas Inconel vuam yog qhov nyuaj dua
Inconel yog npib tsib xee-raws li superalloy tsim los rau siab -kub thiab corrosive ib puag ncig. Cov khoom qub no kuj ua rau nws nyuaj rau vuam.
Los ntawm peb cov kev paub txhawb nqa cov neeg siv khoom lag luam, cov kev cov nyom tseem ceeb suav nrog:
- Kev kub siab ua haujlwm → xav tau ntau lub zog tawm tswv yim
- Ua hauj lwm hardening nyiam → cov khoom yuav nyuaj thaum ua
- rhiab heev rau kev sib kis → me me impurities tuaj yeem cuam tshuam rau qhov zoo ntawm vuam
Peb tau pom cov xwm txheej uas cov vuam tau pom qhov pom tau, tab sis tom qab ntawd qhov ua tsis tiav tau tshwm sim vim muaj kev ntxhov siab sab hauv lossis tswj tsis raug cua sov.
2. Cov txheej txheem vuam ntau rau Inconel
Hauv kev siv tiag tiag, ntau txoj kev vuam siv feem ntau nyob ntawm qhov loj thiab qhov yuav tsum tau ua:
a) TIG welding
Qhov no yog txoj kev siv dav tshaj plaws rau Inconel.
- High precision
- Kev tswj tau zoo tshaj qhov cua sov nkag
- Haum rau nyias mus rau nruab nrab seem
Peb feem ntau pom TIG vuam siv nyob rau hauv aerospace thiab precision khoom Cheebtsam qhov twg weld zoo yog ib qho tseem ceeb.
b) MIG (GMAW) welding
Siv rau:
Thicker seem
Cov kev cai ntau lawm ceev
Nws muaj txiaj ntsig ntau dua li TIG, tab sis yuav tsum tau ua tib zoo tswj xyuas kom tsis txhob muaj cua sov ntau dhau.
c) Laser vuam (hauv cov ntawv thov siab heev)
Hauv qee qhov chaw tsim khoom siab - kawg:
- Heev localized tshav kub input
- Tsawg heev distortion
- High repeatability
Txawm li cas los xij, cov khoom siv thiab cov txheej txheem tswj cov kev xav tau siab dua.
d) Kev tiv thaiv thiab tshwj xeeb vuam
Siv rau hauv cov ntawv thov kev lag luam tshwj xeeb, nyob ntawm cov khoom tsim thiab kev tsim khoom.
3. Yam tseem ceeb uas cuam tshuam rau vuam zoo
Los ntawm peb cov kev paub ua haujlwm nrog cov neeg siv khoom lag luam, kev ua tiav Inconel vuam nyob ntawm ntau yam tseem ceeb:
a) Thaum tshav kub kub tswj
Kev kub ntau dhau tuaj yeem ua rau:
- Cov qoob loo loj hlob
- Txo cov neeg kho tshuab lub zog
- Distortion
Kev siv hluav taws xob kom zoo yog qhov tseem ceeb los tswj cov khoom siv.
b) Filler xaiv cov khoom siv
Kev siv cov hlau muab tub lim kom raug yog qhov tseem ceeb los xyuas kom meej:
- Kev sib xyaw ua ke
- Kev sib koom ua haujlwm ruaj khov
- Corrosion kuj continuity
Kev xaiv muab tub lim tsis raug yog ib qho ua rau muaj qhov ua tsis tiav hauv cov haujlwm tiag tiag.
c) Nto huv si
Inconel rhiab heev rau kev sib kis. Txawm tias me me ntawm:
- Roj
- Plua plav
- Oxides
tuaj yeem cuam tshuam kev ncaj ncees ntawm kev sib tsoo. Hauv qhov chaw tsim khoom, peb ib txwm hais txog kev tu nruj ua ntej vuam.
4. Cov teeb meem vuam ntau hauv kev siv tiag
Raws li qhov kev paub dhau los ntawm qhov project, cov teeb meem nquag tshaj plaws suav nrog:
1. Kev tawg tom qab vuam
Feem ntau tshwm sim los ntawm:
- Kev tswj cua sov tsis raug
- Residual stress
- Cov ntaub ntawv muab tub lim tsis raug
2. Porosity hauv welds
Feem ntau txuas rau:
- Qhov chaw paug
- Tsis txaus shielding gas tiv thaiv
3. Tsis muaj corrosion kuj
Yog tias qhov vuam tsis raug tswj kom zoo, lub tshav kub- thaj tsam cuam tshuam yuav tsis ua zoo li cov khoom siv hauv paus.
Peb tau pom cov neeg siv khoom ntsib teeb meem corrosion tsis txaus ntseeg tsuas yog vim tias kev tshaj tawm -weld kev kho tsis raug siv.
5. Tshaj tawm - vuam kev kho qhov tseem ceeb
Hauv ntau daim ntawv thov kev lag luam, vuam tsis yog kauj ruam kawg.
Tshaj tawm - cov txheej txheem vuam yuav suav nrog:
- Kev kho kev ntxhov siab
- Deg tu los yog pickling
- Kev tshuaj xyuas thiab kev sim
Cov kauj ruam no pab ua kom ntev - lub sij hawm ruaj khov, tshwj xeeb tshaj yog nyob rau hauv siab - kub los yog corrosive ib puag ncig.
6. Tiag -lub ntiaj teb foundations los ntawm kev lag luam siv
Ntawm Jiangsu XuRui Hlau Group Co., Ltd., peb tau pom tias Inconel vuam txoj kev vam meej nyob ntawm cov khoom nws tus kheej thiab ntau ntxiv ntawm cov txheej txheem tswj thiab kev paub.
Hauv zoo - tej yaam num tswj:
- Welds ruaj khov
- Kev ua tau zoo nyob ib puag ncig
- Lub sijhawm ntev - kev ntseeg tau tiav
Hauv qhov chaw tswj tsis tau zoo, txawm tias siab -Inconel zoo tuaj yeem ua haujlwm tsis zoo.
Kev xav kawg
Yog lawm, Inconel tuaj yeem welded-tab sis nws yuav tsum muaj kev tswj hwm thiab kev qhuab qhia ntau dua li cov qauv hlau.
Hauv kev siv tiag tiag, kev vam meej nyob ntawm:
- Xaiv txoj kev vuam zoo
- Tswj cov cua sov nkag
- Kev siv cov khoom ua kom zoo
- Xyuas kom huv si saum npoo thiab tom qab- kho
Thaum cov xwm txheej no raug tswj kom raug, Inconel welds tuaj yeem ua tau zoo txawm tias nyob rau hauv qhov xav tau siab - kub thiab corrosive ib puag ncig.
