Hauv kev tsim khoom niaj hnub, vuam technology yog qhov tseem ceeb rau cov khoom sib txuas. Tig (tungsten inert roj vuam) thiab laser vuam yog ob lub zog vuamCov Khoom Tiv Thaiv Kuvs kuj txawv.
1. Cov ntsiab lus thiab cov ntsiab lus tseem ceeb
1.1 Cov Khoom Cua Sov thiab Zog Hloov Hloov
Tig Vuam:
Siv hluav taws xob ARC (3, 000}}} {{}}}}}}}} {} Cov neeg ua haujlwm tau yaj lub hauv paus hauv paus thiab cov xaij hlau. Argon Gas Shield lub pas dej Molten ntawm oxidation. Nws muab cov tswv yim dav dav kub ({{4 4}}
Laser Vuam:
Tsom rau lub siab-zog-density laser nqaj (1 {}}}}} ⁶-10⁷ w \/ cm²) rau cov khoom melt. Nws cov lus qhia tshav kub tshav kub (0.1-1 kj \/ mm) tsim ib txoj kev nqaim taub hau (1 \/ 3-1 \/ 10 ntawm tus vuam vuam), txias txias, thiab tsawg heev distortion713.

1.2 khoom siv tau
Tig Vuam:
Haum rau: Carbon hlau, hlau stainless, txhuas, titanium (oxidation-rhiab cov hlau), thiab tuab dua lossis sib npaug nrog 3 mm).
Kev txwv: Tsis muaj kev ua tau zoo ntawm tsawg-melting-point ntawm cov hlau (piv txwv li, txhuas) thiab cov ntaub ntawv muaj txiaj ntsig zoo (piv txwv li, tooj liab) 712.
Laser Vuam:
Haum rau: Nyias nplooj ntawv ({0. 1-4 mm), defore hlau (txhuas, tooj liab), thiab cov khoom siv hluav taws xob (pwm). Muaj peev xwm koom nrog cov sib cais (piv txwv li cov hlau-txhuas) 1213.
Kev txwv: High cost for thick plates (>6 hli) thiab cov hlua khi ib yam kom raws txoj cai (sib txawv<0.1 mm)7.
1.3 txheej txheem yam ntxwv
| Chaw ua uas tsis tau haus | Tig Vuam | Laser Vuam |
|---|---|---|
| Hov ceev | Qeeb ({{{0}}. 1-0.5 m \/ min) | Ceev (1-10 m \/ min) |
| Kev tso tshuab ua | Kev ua haujlwm ntawm phau ntawv, muaj automation | Siab automated, neeg hlau-phooj ywg |
| Zog Efficiency | Tsawg (30-40% poob) | Siab (30-50% photiclectric txuag) |

2. Kev Tiv Thaiv Cov Kab Ntawv Xaiv
2.1 Tigran Kev Tiv Thaiv Kev Xav Tau
Hluav taws xob thiab roj phom:
UV \/ IR Hluav Taws Xob: Tig arcs emit nti UV (5-30 × muaj zog dua li vuam). Siv cov kab hlau rhuav nrog cov theem shading ntau dua los yog sib npaug rau Din 12, npog ib 1.5 m radius712.
Ozone thiab fumesDaim ntaub thaiv yuav tsum tau kaw cov npoo (piv txwv li, sib nqus ntoo) thiab sib xyaw nrog cua tshuab (ntau dua lossis sib npaug} m³ \/ h airflow) 7.
Kub-Kub Kuj:
Withstand lub ntsej muag kub txog 1,500 degree. Cov ntaub ntawv yuav tsum tau ntsib ul94 v {kua nplaim-retardant qauv (piv txwv li Nomex fiber ntau nrog silicone-coated iav fiber) 7.
2.2 Laser Vuam kev tiv thaiv kev tiv thaiv
Wavelength thiab optical density (OD):
Txog fiber ntau (1,064 nm) lossis semiconductor lasers (808-980 nm), xaiv cov ntaub ntau dua lossis sib npaug rau 4 (thaiv 99.99% lub zog). Cov ntaub ntawv yuav muaj xws li cov txhuas iav kev sib xyaw lossis polycarbonate txheej13.
Anti-Reflectection Kev Tsim:
Siv cov chaw matte (refirs<8%) to prevent beam reflections. Overlapping seams (≥10 cm width) eliminate scatter leakage1213.
Durability thiab hloov tau:
Xaiv cov kua muag-resistant fabrics (ntau dua los yog sib npaug rau 50 n \/ cm) thiab modular tsim rau kev hloov chaw ua haujlwm kom haum.
3. Economic thiab Daim Ntawv Thov Kev Thov
3.1 Kev Ntsuam Xyuas Them
Thawj zaug kev nqis peev: Tig khoom siv 10-20% ntawm cov tshuab laser tab sis yuav tsum muaj cov nuj nqis txuas ntxiv (Argon roj, electrodes). Lub tshuab laser muaj cov nqi nce siab dua tab sis txo qis kev ua haujlwm ntev ntev kev ua haujlwm.
Ua tau zoo: Laser vuam txo cov nqi zog ua haujlwm los ntawm 60-80%, zoo tagnrho rau cov khoom ntim siab ntau (piv txwv, automotive seem) 7.
3.2 Cov ntawv thov raug
Tig Vuam: Cais cov paib (tuab cov hlau), xa cov kab hlau welding, thiab artisanal hlau imm.
Laser Vuam: Cov neeg siv khoom siv hluav taws xob (roj teeb sib khi), cov khoom siv kho mob (cov ntaub ntawv huv (cov khoom huv (titanium (titanium (titanium Cheebtsam) 1213.
4. Cov Qauv Kev Nyab Xeeb
Tig Vuam:
Xyuas kom meej aronon purity ntau dua los yog sib npaug rau 99.99% thiab hnav UV-tiv thaiv hnyav (thaiv ntau dua lossis sib npaug ntawm 99.9% hluav taws xob) 7.
Laser Vuam:
Ua raws liLaser Kev Nyab XeebCov Qauv (piv txwv li, GB 7247. 1-2012). Nruab Nrab Nruab Nrab (Shutter Teb<0.1 seconds)13.
5. Tag
Tigeer Vuam yog compringary: Tig excled-tau zoo tuab-phaj vuam, thaum lub tshuab laser ua kom zoo dua qub thiab ua haujlwm. Cov ntaub thaiv tiv thaiv yuav tsum ua kom haum nrog cov txheej txheem-tig xav tau UV tiv thaiv thiab roj laser xav tau wavelength-tshwj xeeb od thiab anti-reantose cov khoom. Cov lag luam yuav tsum tau txais kev nyab xeeb kev nyab xeeb (piv txwv, kev rho tawm cov ntxaij vab tshaus + ppe) es tsis tau sib dhos.
