Spot vuamsiv lasers yog ua tau thiab muaj ntau yam zoo dua li cov chaw vuam nrog cov hluav taws xob tam sim no. Tab sis cov lus nug tseem nyob - cov txheej txheem laser-raws li kev sib tw tiag tiag lossis tshaj qhov kev kub ceev, cov khoom siv hluav taws xob ntau ntawm cov tsoos chaw vuam txoj kev siv rau lub cev tsheb, roj teeb tabs thiab lwm cov hlau loj sib dhos? Cia peb tshuaj xyuas cov cuab yeej technology, cov txiaj ntsig thiab kev txwv thaum nws los txog rau laser chaw vuam.
Yuav Ua Li Cas Laser Spot Vuam Ua Haujlwm
Zoo li tus qauv kev tiv thaiv qhov chaw vuam, laser chaw vuam tsom qhov kub ntawm qhov chaw me me kom fuse ua ke cov ntawv hlau hauv ib feem ntawm ib pliag xwb. Tab sis tsis yog siv hluav taws xob tam sim no los ntawm cov lus qhia electrode, lasers mloog zoo rau lub zog kho qhov muag kom nrawm nrawm thiab koom nrog cov hlau.[1]
Qhov ntau thiab tsawg tsawg dua 2 millimeters tso cai rau lub zog siab ceev hloov mus rau hauv cov ntawv txheej steel. Qhov no tsim ib tug weld nugget fusing ua ke cov hlau txheej nyob rau hauv lub laser beam tus ntoo khaub lig seem nyob rau hauv milliseconds.[2]
Vim muaj kev tswj xyuas meej thiab ua tiav sai, laser tuaj yeem tso lub zog txaus los tsim cov chaw welds mus txog 2 hli tob hauv carbon steels hauv qab 10 vib nas this siv tsuas yog 2 kilowatt fiber ntau laser.[3] Qhov kev sib xyaw ua ke ntawm kev ceev, ceev thiab qhov tob ua rau laser qhov kev xaiv tiag tiag rau qhov chaw vuam cov khoom ntim siab.
Qhov zoo tshaj Standard Resistance Spot Welding
Laser qhov chaw vuam boasts ntau yam zoo stemming los ntawm kev ua ib qho kev kho qhov muag es tsis yog cov txheej txheem hluav taws xob:
- Tsis xav tau electrodes
Lasers tshem tawm cov khoom kim heev, hnav-tiv taus electrodes thaum ua kom tsis muaj kev sib cuag. Qhov no kuj txo cov kev sib txhuam thiab electrode indentation marking ntawm cov khoom tiav lawm.[4]
- Siab zog Bonds
Laser tsim welds mus txog 30% siab zog tensile uas pom tsawg micro-cracking los yog porosity teeb meem tshwm sim nrog rau qhov chaw welding.[5]
- Ua haujlwm nrog cov ntaub ntawv tshiab
Lasers tuaj yeem ua tiav qhov chaw vuam kab txawv xws li magnesium lossis txhuas uas ua rau hluav taws xob conductivity thiab cov khoom sib xws teeb meem rau cov qauv chaw vuam.[6]
- Txhim kho txheej txheem tswj / kuaj mob
Lasers muaj kev saib xyuas zoo, tswj thiab kev pom zoo. Cov tsis xws li beam angles, mem tes ntev lossis tsom qhov chaw precisely tune welds.[7] Thiab txoj hauv kev zoo li infrared thermography zoo dua pom cov cua sov hauv lub sijhawm tiag tiag.[8]
Yog li cov lasers nthuav tawm qhov zoo sib xws txawm tias qhov augmenting lossis hloov qhov chaw vuam ua haujlwm ntev. Tab sis kev paub txog cov txiaj ntsig no nyob ntawm kev daws qee qhov kev txwv ntxiv.
Cov kev txwv uas tseem tshuav nrog Laser Spot Vuam
Thaum pom cov lus cog tseg, laser chaw vuam tshuab tseem ntsib teeb meem nyob ib puag ncig:
- Nqi
Lasers 'cov khoom siv siab dua tuaj yeem cuam tshuam kev hloov pauv ntawm cov kab ntau lawm. Lub sij hawm luv ROI tseem nyuaj.[9]
- Ceev
Txheem qhov chaw vuam ua tau zoo heev dhau los ntawm qhov tsis sib xws los ntawm cov txheej txheem laser kom deb li deb. Lasers ua haujlwm ntawm kwv yees li 20% qis dua tam sim no - txawm tias kev txhim kho txuas ntxiv mus ntxiv.[10]
- Diagnostics Imbalance
Thaum laser xyuas nws tus kheej yog superior, xyoo lawm tsim nyog ntawm qhov chaw welding metrology rau kev tswj kom zoo yog tsim. Cov qauv sib npaug, cov kev qhia tshwj xeeb thiab cov txheej txheem kuaj tseem nyob hauv cov theem ua ntej ntawm kev txhim kho rau txoj kev laser.[9]
Yog li kev kuaj mob siab heev yuav tsum tau nthuav dav nrog rau kev txhim kho hauv kev nrawm thiab nqaj shaping kom zoo dua cov txheej txheem txheej txheem ntawm nplai. Tab sis lub sij hawm ntev kev muaj peev xwm tseem nyiam laser ua tiav ntawm qhov sib npaug lossis nrawm dua.
Outlook rau Laser Spot Vuam
Nrog cov txiaj ntsig tseem ceeb hauv kev sib txuas zoo, kev yooj yim thiab kev kuaj mob, laser chaw vuam saws yuav nthuav dav - tshwj xeeb tshaj yog cov khoom tshiab xav tau hloov pauv. Ib qho kev soj ntsuam pom cov tsheb tsav tsheb tau tsav ntau dua 50% kev loj hlob hauv laser vuam khoom muag los ntawm 2020 txog 2025 raws li kev siv hlau sib zog nce ntxiv.[11]
Thiab cov roj teeb ntau lawm kuj ua rau muaj kev cuam tshuam loj heev rau laser qhov chaw vuam ntawm tooj liab tabs thiab foils qhov teeb meem kev sib cuag hluav taws xob tshwm sim. Yog li thaum muaj kev txwv nyob ib puag ncig kev tsim khoom qub kev koom ua ke tseem nyob, laser qhov chaw vuam cov txheej txheem kev txhawb nqa kom ruaj khov siab ntim nkag mus rau lub sijhawm ntev kom ua tau zoo thiab tsim tau zoo.
