1. Dab tsi ua rau muaj qhov tseem ceeb hauv laser vuam?
PorosityHais txog cov roj npuas me me daig sab hauv hauv Weld Seam thaum Sandolification. Cov voids no txo cov tshuab kho tshuab muaj zog thiab tuaj yeem ua raws li cov ntsiab lus rau cov kab nrib pleb lossis corrosion.
Lub ntsiab ua rau porosity:
Kev Tiv Thaiv Kev Tiv Thaiv Cov Roj Tsis Txaus
Kev thaiv cov roj zoo li argon lossis nitrogen yog siv los tiv thaiv cov paug ntawm cov nplaim paug. Yog tias cov roj ntws tsawg dhau, tsis sib xws, lossis tsis raug cai, oxygen thiab dej vapor tuaj yeem nkag rau hauv Weld pas thiab ua rau cov roj npuas.
Cov khoom tsis huv workpiece
Roj, xeb, pleev xim, lossis lwm yam paug ntawm cov hlau nto tuaj yeem vaporize thaum lub sij hawm tsim av uas tau daig hauv cov pas dej molten.
Tsis raug cai loas trackers
Ntau dhau nrawm, lub zog qis, lossis tsis ruaj khov ua kom pom tseeb tuaj yeem tiv thaiv tag nrho Vapor khiav tawm, nce cov porfoshood tag nrho, ua kom muaj kev khav theeb.
2. Dab tsi ua rau tawg hauv laser elsas?
TawgYog soliorification -} Cov tsis xws luag uas tshwm sim thaum cov nroj tsuag molten hlau tsis xwm yeem, ua rau sab hauv kev ntxhov siab dhau ntawm cov khoom muaj zog.
Lub ntsiab ua rau tawg:
Kev Tiv Thaiv Kev Tiv Thaiv Tsis Zoo
Zoo ib yam li Porosity, tsis txaus tiv thaiv pub rau oxygen thiab lwm yam roj uas ua rau cov hlau molten, sib sau ua cov kab mob uas tsis muaj zog thiab txhawb nqa cov kab tawg.
Lub siab txias los yog kev faib tawm tshav kub kub
Tshwj xeeb tshaj yog nrog high - Reflective cov ntaub ntawv (zoo li cov neeg siv tawv me me tuaj yeem ua rau muaj kev ntxhov siab thiab cua sov, uas ua rau tawg.
Cov khoom siv tsis sib xws lossis sib koom ua ke geometry
Qhov sib txawv ntawm cov khoom nthuav dav, tsim nyog sib koom ua ke, lossis cov khoom siv sib txuas tsis sib xws tuaj yeem ua rau muaj kev ntxhov siab ntawm Weld Seam.
3. Yuav ua li cas tiv thaiv porosity thiab kab nrib pleb?
Cov kev coj ua zoo tshaj plaws:
Xyuas kom meej cov kev tiv thaiv roj kev xaiv thiab xa tuaj
Siv siab -}}}}}}}}} }rogen, tswj hwm kom raug tus nqi txaus (feem ntau 15 min), thiab ncaj qha rau lub kaum sab xis kom tsim nyog rau weld.
Ntxuav ntawm cov khoom siv hauv paus kom huv si
Tshem cov roj, pleev xim, oxides, noo noo, thiab hmoov av ua ntej vuam. Siv txhuam cov kws txhuam hniav, ntxuav tshuaj, lossis laser ntxuav yog tias tsim nyog.
Ua kom tau zoo Laser tsis sib xws
Teem lub hwj chim tsim nyog, nrawm, thiab tsom mus rau kom muaj peev xwm ruaj khov thiab kev khiav tawm hauv siab. Ib qho txheej txheem ruaj khov txo cov kev cuam tshuam rau sab hauv.
Siv preheating thiab post - Weld Kev Kho Tshav Kub (yog xav tau)
Tshwj xeeb rau tawg -} Cov ntaub ntawv rhiab, preheating tuaj yeem txo cov thermal gradients thiab qis sab hauv kev ntxhov siab.
Tag
Porosity thiab cov kab nrib pleb yog ob qho ntawm feem ntau cov teeb meem hauv laser vuam. Txawm li cas los xij, nrog cov khoom tiv thaiv kom zoo, cov ntaub ntawv huv, thiab cov txheej txheem kho kom zoo, cov tsis xws luag tuaj yeem txo qis lossis zam. High {- Cov khoom siv tau zoo tsis yog ua kom muaj zog thiab tseem txuas ntxiv rau lub neej thiab kev ntseeg tau ntawm cov khoom kawg.
