Raws li cov khoom siv tshiab, stainless hlau yog dav siv hauv aerospace, nws pib qhov chaw thiab lwm qhov chaw vim nws tus kheej cov yam ntxwv ntawm kev txhim kho corrosion thiab kev ua haujlwm. Cov cuab yeej siv tshuab laser vuam tshuab ua lub luag haujlwm tseem ceeb hauv kev thov kev lag luam steel hlau, tshwj xeeb tshaj yog nyob rau hauv kev lag luam tsheb, lub cev txuas txhua yam los ntawm vuam. Txawm li cas los xij, hauv cov txheej txheem welding, nws yog kev tsis pom zoo tias nws yuav muaj kev cuam tshuam los ntawm ntau yam, xws li stainless hlau phaj vuam deformation, tswj kev nyuaj, thiab lwm yam, uas tsis tau txais txiaj ntsig rau kev txhim kho txuas ntxiv ntawm cov teb. Yog li ntawd, nws yog qhov tseem ceeb rau kev ntxiv dag zog rau kev tshawb fawb ntawm cov laser welding deformation ntawm stainless hlau daim hlau.
Ntawm no yog peb daim duab peb ntu neeg hlau looj lub tshuab nqus hlau uas tsim nyog rau vuam hlau ntau
Peb lub tshuab ua haujlwm loj rau cov roj voos laser vuam tshuab yog lub tshuab ua kom muaj lub ntsej muag tshiab peb lub vuam tshuab tshwj xeeb tsim los ntawm peb lub tuam txhab raws li cov neeg siv xav tau. Lub tshuab siv cov kis tau tus mob optical fiber ntau thiab siv cov txheej txheem kev tswj hwm kev tswj hwm kom hloov kho txoj kev vuam. Nws tau hloov kho qhov vuam ntawm cov seem. Cov tsoos Kev ua lag luam vuam ntawm cov khoom tshwj xeeb zoo nkauj yog qhov nyuaj thiab ntau yam. Lub tshuab hluav taws xob laser tshuab rau peb-txoj kab kev sib tw tuaj yeem hais tau tias yog tsim tshwj xeeb rau feem tshwj xeeb seem ntu vuam tshuab.
Peb qhov tseem ceeb cuam tshuam rau kev deformation ntawm welded stainless hlau yog vuam tam sim no, mem tes dav thiab zaus.
1) Vuam tam sim no nce, yog li ntawd qhov dav ntawm lub qhov rooj sib dhos, uas yog nquag nquag thiab lwm yam tshwm sim, ua rau oxidative deformation ntawm lub weld nto;
2) Qhov nce hauv mem tes dav dav ntxiv qhov muaj zog ntawm qhov sib txuas ntawm welded. Thaum lub mem tes dav nce mus txog ib qib, qhov kev txiav txim siab kub siv lub zog ntawm cov khoom kuj nce ntxiv, ua rau thaj chaw me me ntawm thaj tsam ntawm cov khoom sib koom ua ke;
3) Qhov cuam tshuam ntawm vuam zaus ntawm vuam vuam tsoo ntawm cov hlau stainless phaj muaj feem xyuam nrog tuab ntawm steel phaj. Piv txwv li, rau 0. 5 hli steel phaj, thaum qhov zaus mus txog 2 Hz, lub weld sib tshooj tus nqi ntau dua; thaum lub zaus mus txog 5 Hz, lub weld seam Lub qhov cub hnyav, qhov ntau ntawm cov cua sov cuam tshuam rau thaj tsam, thiab deformation.
Nta ntawm 3 D neeg hlau laser vuam tshuab
1. Lub laser ua lub taub hau ntxiv CCD soj ntsuam thiab saib, uas tuaj yeem saib cov vuam nyhuv hauv lub sijhawm tiag tiag;
2. Tom qab laser tsom, lub zog ceev tau loj, thiab micro vuam tuaj yeem ua;
3. Lub teeb nrig laser tuaj yeem muab qhov chaw me me tom qab tsom, thiab tuaj yeem muab tso kom yog thiab tuaj yeem thov rau kev siv ntau lawm.
