Vim lub zog ceev ceev thiab ceev lub zog tso tawm ntawm laser vuam, cov kev ua tau zoo yog siab dua li cov txheej txheem ib txwm muaj. Laser vuam kev ua tau zoo dua ua cov yam ntxwv ntau dua li kev ua ib txwm ua. Laser vuam siv siab -lub zog laser pulses kom sov cov khoom hauv ib cheeb tsam me. Lub zog ntawm laser hluav taws xob yog coj mus rau sab hauv diffusion ntawm cov khoom los ntawm kev hloov mus rau tshav kub, thiab cov khoom yog melted los ua ib tug tshwj xeeb molten pas dej ua ke. Yog li dab tsi yog daim ntawv thov ntawm laser vuam tshuab?
1. Kev tsim khoom
Laser tailor vuam tshuab tau siv dav hauv kev tsim tsheb txawv teb chaws. Raws li kev txheeb cais, xyoo 2000, muaj ntau tshaj 100 laser tailor welding cov kab ntau lawm rau kev txiav cov phaj dawb thoob ntiaj teb, nrog rau txhua xyoo cov khoom tsim tawm ntawm 70 lab daim ntawm lub tsheb tiv thaiv tailor vuam daim hlau, thiab tseem loj hlob ntawm tus nqi siab. Qee cov qauv txiav dawb kuj tau txais kev tsim khoom siv hauv tsev thiab cov qauv tuaj txawv teb chaws. Nyob rau hauv Nyiv, CO2 laser welding yog siv los hloov flash pob tw vuam rau kev sib txuas ntawm dov steel coils hauv kev lag luam steel. Nyob rau hauv kev tshawb fawb ntawm ultra-thin phaj vuam, xws li cov ntawv ci nrog lub thickness tsawg dua 100 microns, fusion vuam tsis tuaj yeem nqa tawm, tab sis YAG laser vuam nrog tshwj xeeb tso zis hluav taws xob waveform ua tiav, uas qhia tau hais tias yav tom ntej dav ntawm laser welding. Nyiv kuj tau ua tiav tsim YAG laser vuam thawj zaug hauv ntiaj teb rau kev saib xyuas cov tshuab hluav taws xob cov raj hauv cov tshuab hluav taws xob nuclear, thiab kuj tau ua cov iav laser vuam tshuab hauv Suav teb.
2. Powder Metallurgy
Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, ntau yam kev lag luam thev naus laus zis muaj cov kev cai tshwj xeeb rau cov khoom siv, thiab cov khoom tsim los ntawm smelting thiab casting tsis tuaj yeem ua tau raws li qhov xav tau. Vim muaj cov khoom tshwj xeeb thiab kev tsim cov khoom zoo ntawm cov hmoov metallurgy cov ntaub ntawv, lawv tau hloov cov khoom siv hlau metallurgical hauv qee qhov chaw, xws li tsheb, dav hlau, cuab yeej thiab cov cuab yeej txiav. Nrog rau kev loj hlob ntawm cov khoom siv hmoov metallurgy, kev sib txuas ntawm cov hmoov metallurgy cov ntaub ntawv thiab lwm qhov chaw tau dhau los ua qhov tseem ceeb, uas txwv tsis pub siv cov khoom siv hmoov metallurgy. Thaum xyoo 1980s, laser vuam nkag mus rau hauv cov khoom siv hlau metallurgy ua haujlwm nrog nws cov txiaj ntsig tshwj xeeb, uas tau qhib qhov kev cia siab tshiab rau kev siv cov hmoov hlau metallurgy. Piv txwv li, txoj kev brazing feem ntau siv rau hauv kev sib txuas ntawm cov hmoov hlau metallurgy cov ntaub ntawv yog siv los vuam pob zeb diamond, uas ua rau lub melting thiab ntog tawm ntawm solder vim tsis tshua muaj zog bonding thiab dav tshav kub cuam tshuam cheeb tsam, tshwj xeeb tshaj yog tsis tuaj yeem hloov mus rau qhov kub thiab txias. Lub zog xav tau, Laser vuam tuaj yeem txhim kho vuam lub zog thiab kub ua haujlwm.
3. Automotive Industry
Thaum xyoo 1980s, kW laser tau ua tiav rau kev tsim khoom. Tam sim no, laser vuam ntau lawm kab tau tshwm sim nyob rau hauv lub tsheb tsim kev lag luam ntawm ib tug loj teev thiab tau dhau los ua ib tug zoo kawg nkaus achievements ntawm lub tsheb manufacturing kev lag luam. Raws li thaum ntxov xyoo 1980s, European tsheb tuam txhab lag luam tau ua tus thawj coj hauv kev siv laser vuam rau cov ntawv hlau vuam xws li lub ru tsev, lub cev thiab sab ncej. Nyob rau xyoo 1990, Tebchaws Asmeskas tau npaj txhij txog kev siv laser vuam rau hauv kev tsim tsheb. Txawm hais tias nws pib lig, nws loj hlob sai. Ltalis siv laser vuam nyob rau hauv vuam thiab sib dhos ntawm feem ntau steel phaj Cheebtsam, thiab Nyiv siv laser vuam thiab txiav cov txheej txheem nyob rau hauv lub tsim ntawm lub cev panels. Lub zog siab steel laser vuam sib dhos yog ntau thiab ntau siv hauv kev tsim cov tsheb lub cev vim tias lawv cov kev ua tau zoo heev. Raws li kev txheeb cais ntawm Asmeskas kev lag luam hlau, los ntawm qhov kawg ntawm 2002, Kev noj cov laser welded steel qauv yuav ncav cuag 70000t, uas yog peb zaug ntau dua li xyoo 1998. Raws li cov yam ntxwv ntawm cov khoom loj thiab qib siab ntawm automation hauv tsheb. kev lag luam, laser vuam khoom yog tsim nyob rau hauv cov kev taw qhia ntawm lub hwj chim siab thiab multi-channel. Nyob rau hauv cov nqe lus ntawm cov txheej txheem, Sandia National Laboratory ntawm lub tebchaws United States thiab Pratt Witney koom ua kev tshawb fawb txog kev ntxiv hmoov hlau thiab hlau nyob rau hauv tus txheej txheem ntawm laser vuam, thiab Bremen lub koom haum ntawm thov beam technology ntawm lub teb chaws Yelemees tau ua ntau yam kev tshawb fawb ntawm laser vuam aluminium alloy. lub cev ncej. Nws yog suav hais tias ntxiv muab tub lim nyob rau hauv lub weld yog pab kom tshem tawm cov thermal tawg thiab txhim kho vuam ceev, kom daws tau qhov teeb meem kam rau ua, cov tsim ntau lawm kab tau muab tso rau hauv ntau lawm nyob rau hauv lub Hoobkas.
