Laser Vuam yog dab tsi? Cov txiaj ntsig ntawm Laser Vuam Tshuab yog dab tsi?

Laser Welding yog dab tsi? Cov txiaj ntsig ntawm yog dab tsi?Cov Tshuab Vuam Laser?

Kev vuam laser yog ib txoj kev vuam uas siv lub teeb laser muaj zog siab tsom mus rau thaj chaw vuam kom yaj cov khoom hauv zos sai sai thiab tsim cov pas dej molten. Thaum lub pas dej txias, kev sib txuas zoo ntawm cov khoom raug ua tiav. Nws cov yam ntxwv tseem ceeb yog lub zog muaj zog heev, cua sov sai, thiab kev tsim cov vuam meej.

Ua cov khoom siv, cov tshuab laser vuam muaj cov txiaj ntsig zoo tshaj plaws hauv qhov zoo, kev ua haujlwm zoo thiab kev hloov pauv tau, daws tau ntau qhov mob ntawm kev vuam ib txwm muaj. Cov ntsiab lus yog raws li nram no:

Ua Ntej: Dab Tsi Yog TseebKev vuam laser?

Lub hauv paus ntsiab lus ntawm laser welding tuaj yeem tawg ua peb kauj ruam:

Lub tshuab hluav taws xob laser tsim cov teeb laser muaj zog heev, uas raug tsom los ntawm lub kaw lus kho qhov muag kom ua tiav lub zog ceev ntawm 10⁴–10⁶ W/cm².

Lub teeb laser uas tsom mus rau qhov chaw ua haujlwm rau ntawm qhov chaw ntawm cov ntaub ntawv uas yuav tsum tau welded (xws li stainless hlau, aluminium alloy, carbon steel, thiab lwm yam), tam sim ntawd cua sov thaj chaw hauv zos mus rau lub xeev molten thiab tsim ib lub pas dej molten.

Thaum lub teeb laser txav mus raws txoj kev uas tau teeb tsa ua ntej, lub pas dej ua kua tsim tas li thiab txias sai, thaum kawg tsim kom muaj qhov txuas ntxiv mus, sib txuas ntom ntom rau kev sib koom ua ke tsis muaj qhov tsis sib xws.

Piv nrogKev vuam arc ib txwm muaj thiab kev vuam argon arc, laser vuam tsis xav tau electrodes lossis filler wire (wire tsuas yog siv rau qee kis). Nws tsuas yog siv laser zog, ua rau muaj kev cuam tshuam thermal tsawg dua rau cov khoom siv.

Cov Zoo Tshaj Plaws ntawm Laser Vuam Tshuab

Plaub lub zog tseem ceeb los ua kom tau raws li qhov xav tau ntawm kev tsim khoom

1. Kev Zoo Tshaj Plaws Vuam: Kev Ntsuas Siab, Kev Hloov Pauv Qis, Kev Ua Haujlwm Tsawg Dua

Kev ua haujlwm vuam zoo dua: Lub zog laser concentrated tsim cov vuam nqaim (zoo li 0.1 hli) nrog kev nkag mus sib npaug, tsawg dua qhov hws thiab cov khoom sib xyaw. Lub zog tensile thiab kev tiv thaiv tawg tau txhim kho los ntawm 20% -30% piv rau kev vuam ib txwm muaj, ua rau nws zoo tagnrho rau cov khoom siv kho mob, cov khoom siv hluav taws xob thiab lwm yam kev siv siab.

Tsawg tshaj qhov ua haujlwm tsis zoo: Thaj chaw uas raug cua sov tsuas yog 1/5 txog 1/10 ntawm kev vuam ib txwm muaj. Thaum vuam cov hlau tsis xeb nyias li 0.5 hli, kev khoov yuav luag raug tshem tawm, txo qhov ncaj thiab sib tsoo tom qab vuam.

Kev zoo nkauj huv si: Cov vuam du thiab tiaj tiaj yuav tsum tau txhuam me ntsis lossis tsis tas yuav txhuam, zoo meej rau cov khoom tseem ceeb xws li cov khoom siv hlau thiab cov khoom siv hauv tsev.

2. Kev Ua Haujlwm Zoo Dua: Kev Ceev Ceev, Kev Ua Haujlwm Siab Dua, Cov Nqi Ua Haujlwm Tsawg Dua

Kev vuam ceev ceev: Lub zog ceev ceev ua rau muaj kev nrawm nrawm 3–5 zaug dua li kev vuam argon arc ib txwm muaj. Rau cov hlau carbon 2 hli, qhov ceev tuaj yeem ncav cuag 10–15 hli / s, ua rau lub voj voog tsim khoom luv dua.

Kev siv tshuab yooj yim: Cov tshuab laser welders tuaj yeem koom ua ke nrog CNC systems, robotic caj npab lossis pom kev rau kev tso saibkev vuam txoj kev tsis siv neeg, txo kev vam khom rau kev ua haujlwm tes thiab ua kom muaj kev ua haujlwm zoo sib xws.

Kev kho ua ntej yooj yim dua: Cov kev cai huv ntawm qhov chaw tsis nruj heev; cov roj me me lossis cov txheej oxide tuaj yeem tshem tawm ncaj qha los ntawm lub zog laser, txuag lub sijhawm npaj.

3. Ntau Daim Ntawv Thov: Siv tau rau cov ntaub ntawv nyias/tuab thiab sib txawv

Kev sib xws ntawm cov khoom siv dav dav: Vuam cov hlau tsis xeb, cov hlau carbon, cov hlau txhuas, cov hlau tooj liab thiab ua rau muaj kev sib txuas hlau sib txawv (piv txwv li, cov hlau tsis xeb rau cov hlau carbon, cov hlau txhuas rau magnesium), kov yeej cov kev txwv ntawm cov txheej txheem ib txwm muaj.

Kev hloov pauv tau yooj yim ntawm cov khoom ua haujlwm: Ua haujlwm tau zoo rau cov khoom me me (0.1 hli) xws li cov koob sensor thiab cov phaj tuab tshaj 10 hli (nrog cov qauv muaj zog siab). Kev sib koom ua ke ntawm cov neeg hlau ua rau muaj kev vuam zoo ntawm cov duab tsis sib xws thiab cov kev nyuaj, pab txhawb rau tsheb, hlau ntawv, aerospace thiab lwm yam lag luam.

4. Cov Nqi Siv Ntev Tsawg Dua: Cov Khoom Siv Tsawg Dua, Kev Kho Yooj Yim Dua

Tus nqi siv tsawg: Tsis tas siv cov pas nrig vuam lossis cov hlau nplaum loj; tsuas yog xav tau me ntsis roj tiv thaiv (piv txwv li, argon). Tus nqi siv mus sij hawm ntev txo qis dua 30% piv rau kev vuam ib txwm muaj.

Kev saib xyuas yooj yim: Cov qauv me me, lub neej ntev ntawm cov khoom tseem ceeb (qhov chaw laser, lub taub hau laser) tshaj 10,000 teev. Kev saib xyuas niaj hnub tsuas yog suav nrog kev ntxuav cov khoom siv optics thiab kuaj xyuas cov tshuab txias.

Qhov txwv ua haujlwm qis: Tsis tas yuav muaj cov kws vuam uas muaj kev txawj ntse heev; cov neeg ua haujlwm tshiab tuaj yeem paub siv yooj yim hauv 1-2 lub lis piam, txo kev vam khom rau cov neeg ua haujlwm laus.
