Cov khoom lag luam hlau tsis muaj qhov txhia chaw hauv peb lub neej, los ntawm cov dav hlau, nkoj, tsheb, cov kab kev lag luam ntau lawm, mus rau cov cuab yeej siv kho mob, kub thiab nyiaj kub, thiab lwm yam. Cov kev siv vuam vaus txuas nrog cov khoom lag luam stainless hlau yog argon arc vuam, tiv thaiv kev vuam thiab yog li ntawm, tab sis muaj ntau yam tsis xws luag, tshav kub ua haujlwm ntawm cov kab nrib pleb thiab lwm yam. Cia wb mus saib cov kev qhia ntawm stainless hlau laser vuam tshuab thiab qhov zoo ntawm stainless hlau laser vuam tshuab.
Taw qhia ntawm laser vuam tshuab rau stainless hlau:
Lub tshuab siv qe hlau stainless hlau yog siv lub zog siab pulsed laser los weld cov khoom. Los ntawm kev tawm xenon lub teeb mem tes nrog laser lub zog qhov, laser nthwv dej nrog qee qhov zaus thiab mem tes dav dav yog tawg rau Nd3 +: YAG siv lead ua los ntawm kev tsom kab noj hniav. Cov duab siv hluav taws xob tawm 1064 nm pulsed laser tom qab resonance, thiab tom qab ntawd yog welded los ntawm nqaj nthuav, kho thiab tsom.
Qhov zoo ntawm lub tshuab xaim laser rau lub tshuab xeb:
1. Kev nrawm nrawm, qhov tob loj thiab me me deformation.
2. Nws tuaj yeem txuas nyob rau hauv chav tsev lossis hauv qhov xwm txheej tshwj xeeb. Laser vuam cov khoom siv yog qhov yooj yim. Piv txwv li, cov nqaj hlau laser yuav tsis hloov los ntawm lub zog hluav taws xob; nws tuaj yeem txuas rau hauv lub tshuab nqus tsev, huab cua thiab qee qhov roj ib puag ncig, thiab tuaj yeem txuas tau los ntawm iav los yog cov ntaub ntawv pob tshab.
3. Nws tuaj yeem txuas cov ntaub ntawv refractory xws li titanium, thiab tuaj yeem txuas cov ntaub ntawv sib tov nrog qhov ua tau zoo.
4. Tom qab laser tsom, lub zog ceev tau nce. Thaum cov cuab yeej hluav taws xob muaj qhov hluav taws xob welded, qhov piv txwv yuav ncav cuag 5: 1, thiab qhov siab tshaj plaws yuav ncav cuag 10: 1.
5. Miniature welding tuaj yeem nqa tawm. Lub teeb nrig laser tuaj yeem muab tau qhov chaw me me tom qab tsom, thiab tuaj yeem muab tso kom raug. Nws tuaj yeem siv rau kev sib dhos vuam ntawm micro thiab cov khoom ua haujlwm me me uas ua rau ntau ntau.
6. Nws muaj qhov hloov loj uas siv cov hlau tsis txuas ntev ntev rau qhov chaw uas nyuaj rau qhov txuas tau yooj yim. Tshwj xeeb nyob rau hauv xyoo tas los, optical fiber ntau kis tshuab tau siv hauv YAG laser ua cov thev naus laus zis, uas ua rau laser vuam txuas ntxiv tau txais kev pom zoo thiab siv.
7. Cov kab hluav taws xob tau yooj yim kom paub cov nqaj sib cais raws li lub sijhawm thiab chaw. Nws tuaj yeem ua cov kab ntau thiab ntau lub chaw nres tsheb ib txhij, uas muab cov xwm txheej rau ntau dua vuam.
