Yam cuam tshuam nrog rau Weld Bead Dav Dav nyob Laser Vuam Machine
Weld Bead Dav Dav Dav Hlau Hauv Laser Vuam yog cuam tshuam rau hauv Laser Incarers, cov khoom siv hloov kho, thiab lwm yam sab nraud {}} hauv qab yog cov ncauj lus kom ntxaws:
1. laser tsis muaj
(1) lub zog laser
Ntau zog zog → Werider Weld (ntau lub tswv yim cua sov, loj melt pas dej) .
Qis zog → nqaim weld (tsawg dua nkag mus, ua tau tsis muaj fusion) .
(2) nqaj hom (nqaj zoo)
Ti {{000 (Gaussian nqaj) → nqaim, tob tob ultrasonic (siab zog).
Ntau hom kab teeb → dav, hluav taws xob veels (lub zog ntau dua impersed) .
(3) mem tes tsis (rau cov pulsed lasers)
Siab dua → Werider Weld (ntau sib tshooj pulses) .
Ntev mem tes dav → Werider Weld (ncua kev tawm tshiab) .
Siab dua lub voj voog → Werider Weld ** (ntev zog sib txawv) .
{{0 {}} qhov system optical
(1) tsom xam qhov chaw
Loj loj → Weld Weld (qis zog hluav taws xob ntom ntom) .
Cov chaw me → nqaim weld (siab dua lub zog) .
(2) kev tiv thaiv (nqaj chaw nqaj)
Zoo defocus (saum toj workpiece) → Wird Weld .
Tsis zoo defocus (hauv qab workpiece) → Wird Weld .
Xoom defocus (nyob saum npoo) → Nquag weld .
(3) Focal ntev ntawm lub lens
Ntev focal ntev → loj loj → i weld .
Tus luv luv focal ntev → me me chaw → nqaim weld .
3. txheej txheem tsis txheeb
(1) VUAM CEEV
Siab dua → nqaim weld (tsawg dua cov lus tawm thaum tshav kub) .
Qis dua ceev → spider weld (ntau dua hluav taws xob) .
(2) Kev Tiv Thaiv Roj
Roj roj (ar, nws, n₂) → cuam tshuam rau cov ntshav puas cuam tshuam thiab tus nqi txias dua .
Ntau dua roj ntws → me ntsis nqaim weld (sai dua txias) .
(3) Cov kav hlau (rau laser hlau vuam)
Thicker hlau → Werider Weld (yuav tsum muaj zog ntau rau yaj) .
Cov nqi hlau pub dua → Werider Weld (Ntau cov tub lim cov khoom xa tawm) {.
4.} Cov Khoom Siv Khoom Siv
(1) thermal conductivity
Kev ua haujlwm siab (e {. g}}}}} → nqaim weld (tshav kub dissipates sai sai).
Tsis muaj kev tshaj lij (e {{{{0} g}}}}}}}} → Weld Weld (cua sov nyob sab nrauv) .
(2) Cov Khoom Thickness
Thicker cov ntaub ntawv → Weld Weld (ntau zog xav tau) .
Thinner cov ntaub ntawv → nqaim weld (tsawg zog yuav tsum tau) .
(3) qhov xwm txheej
Oxides, cov tsho loj, lossis cov tshuaj paug → cuam tshuam licker nqus → iurregular weld dav {}}
5. lwm yam
(1) Kev teeb tsa sib koom ua ke
Pob tw, lap, lossis cov pob qij txha sib txawv → Ntau yam kub dissipation → cuam tshuam rau Weld Dav .
(2) nqaj oscillation (tab tom hlab)
Oscillating Laser Beam → Weld Weld (siv rau gap bridging los yog tuab daim hlau) .
(3) ib puag ncig ib puag ncig
Ambient kub / av noo → Cov Cuam Tshuam Me Me Rau Cov Hluav Taws Xob Txias .
Ntsiab lus: Yuav ua li cas tswj Weld Bead Dav Dav?
| Lub hom phiaj|Txoj kev hloov kho |
| Nce dav|↑ Hwjchim, ↓ Defocus, ↑ Qhov chaw loj, siv tuab xaim xaim, oscillate nqaj |
| Txo Dav|↓ Hwjchim, ↑ Ceev, Xoom Defocus, ↓ Qhov loj, siv cov hlau loj, siv cov hlau loj, tem {} hom |
Rau kev ua tau zoo tshaj plaws, kev sim ntawm kev sim (doe) raug nquahu kom cov khoom siv zoo raws li cov khoom siv thiab cov ntawv thov}
