Yuav ua li cas xaiv lub hwj chim ntawm Laser Vuam Tshuab? Kev sib raug zoo raws li Workpiece Thickness thiab Khoom

Yuav ua li cas xaiv txoj cai Laser-Vuam fais fab  

Lub zog ntau dhau = nkim zog thiab hlawv-los ntawm; tsawg dhau = tsis muaj kev nkag mus thiab tsis nrawm. Tsis txhob kwv yees - tsuas yog xauv rau ob yam: workpiece thickness thiab cov khoom coj cwj pwm. Sib phim lawv raws nraim thiab koj tau txais qhov zoo, ceev thiab tus nqi khiav qis. Ntawm no yog daim ntawv qhia yooj yim-English.

1. Pib nrog thickness: lub 'power rule-of-thumb'  

Laser fais fab teeb tsa qhov tob ntawm qhov sib txuas-thicker hlau xav tau ntau watts. Siv stainless li lub hauv paus thiab nplai los ntawm qhov ntawd.

- Daim ntawv nyias (0.5–2 mm) → 500–1 000 W  

 1 hli stainless: 800 W muab lub tiaj tus, huv si hlaws ntawm 3-5 mm s⁻¹—zoo tagnrho rau cov khoom siv hluav taws xob, khoom siv me me.

- Cov phaj nruab nrab (2–5 mm) → 1 000–2 000 W  

 3 hli stainless: 1 500 W ntawm 3-5 mm s⁻¹ muab kev nkag mus rau tag nrho yam tsis muaj lub sij hawm sluggish-zoo meej rau nws pib qhov chaw, cookware.

- Cov phaj tuab (≥ 5 mm) → 2 000 W thiab nce  

 8 hli me me hlau: 3 000 W hauv ntau hom ua tiav qhov sib sib zog nqus, cov pob qij txha muaj zog rau cov qauv thav duab lossis cov kav dej.

Nco ntsoov: ntawm tib lub hwj chim, kev mus qeeb qeeb = sib sib zog nqus weld; sai = ntiav. Txhim kho lub watts ua ntej, tom qab ntawd kho qhov nrawm-tsis txhob crank lub zog dig muag.

2. Qhov tseem ceeb ntawm cov hlau: txhua tus muaj 'lub zog qab los noj mov'  

Absorption thiab thermal conductivity hloov qhov kev ua si txawm nyob rau tib lub thickness.

 Stainless: absorbs zoo, nruab nrab conductivity-siv daim ntawv saum toj ncaj.  

 Cov hlau me me: absorbs me ntsis, ua ntau dua; mus ~ 20% siab dua. 5 hli me steel → 2 000 W es tsis txhob 1 500 W.  

 Aluminium: muaj kev cuam tshuam zoo heev, super kub dab dej. Xav tau cov kua txiv hmab txiv ntoo ntxiv ntxiv rau twin-pulse waveforms. 2 hli Al → 1 500 W yam tsawg kawg nkaus; 1000 W muab porous, discontinuous hlaws.  

 Copper: heev reflectivity + conductivity. Deg prep (blackening) thiab ≥2 500 W rau 3 mm Cu yog yuav tsum tau.

3. Ob daim teb ua kom yuam kev kom tsis txhob yuav tus neeg yuav khoom  

1. Ib txwm khiav daim coupon xeem ntawm seem ua ntej. Kos qhov nkag mus, porosity, distortion - ces zoo-tune.  

2. Tsim nyob rau hauv ib qho chaw me me. Yog tias koj qhov chaw sib txawv ntawm 1-2 hli, xaiv lub zog nruab nrab (piv txwv li 1 000 W) yog li ib lub tshuab npog qhov sib kis tsis tas yuav rov teeb tsa.

Xaiv lub laser fais fab uas phim cov tuab tiag tiag thiab cov khoom siv tiag tiag, thiab koj lub welder yuav xa cov nqi siab tshaj plaws - tsis muaj kilowatts khib nyiab, tsis muaj cov pob qij txha tsis muaj zog.
