Yuav Ua Li Cas Laser Ntxuav Welds: Phau Ntawv Qhia Txog Kev Xaiv Parameter

Lub hauv paus ntawm laser tu ntawm welds yog nyob rau hauv xaiv txoj cai laser hom thiab txuam nws mus rau lub vuam, es tsis yog tsuas yog nrhiav lub zog siab. Raws li lub tuam txhab ua lag luam nyob rau hauv laser tu, SDQY Laser tshwj xeeb tshaj yog cov ntsiab lus hais tias weld tu scenarios yuav tsum tsom rau peb qhov tseem ceeb qhia:

 

1. Pulse Width Matching: Siv 10-20ns luv-mem tes lasers kom tshem tawm cov nplai oxide tuab, siv lub zog ncov kom kov yeej adhesion; hloov mus rau 50-100ns nruab nrab-mem tes lasers rau precision welds (xws li stainless hlau cov cuab yeej kho mob) kom tsis txhob nthuav dav tshav kub-tshem tawm tsam.

 

2. Lub wavelength thiab cov khoom sib txuam: Rau cov pa roj carbon steel thiab qis - alloy steel welds, ua ntej 1064nm infrared lasers nrog tus nqi nqus ntau tshaj 85%; rau cov hlau uas tsis yog-ferrous xws li aluminium alloys thiab titanium alloys, siv 532nm ntsuab lasers los daws qhov teeb meem siab infrared reflectivity, txhim kho kev tu kom zoo los ntawm 30%.

 

3. Fais Fab Ceev Tswj: Qhov tseem ceeb nyob rau hauv "kev tswj gradient"- lub zog ntom ntom ntawm cov ntug vuam raug txo mus rau 3-5kW / cm² los tiv thaiv substrate melting; the power density in the central contaminant concentration area is increased to 8-12kW/cm² to ensure thorough cleaning.

 

 

Peb cov ntsiab lus tseem ceeb txiav txim siab ntxuav cov txiaj ntsig thiab kev nyab xeeb substrate

1. Spot Control: Los ntawm Kho kom haum rau Dynamic Adaptation
Kev kho qhov chaw ruaj khov feem ntau ua rau kev tu tsis tiav lossis khawb ntawm cov hauv paus hniav. Cov txheej txheem siab tshaj plaws suav nrog: Siv lub tshuab ua kom pom tseeb qhov chaw, kho qhov chaw txoj kab uas hla (0.5-2mm) hauv lub sijhawm tiag tiag raws li qhov dav dav (2-10mm) txhawm rau ua kom tiav kev pabcuam; Siv "kauv scanning hom" rau fillet welds thiab pob tw welds nrog lub scanning galvanometer kom tsis txhob muaj qhov sib tshooj thiab hauv zos overheating.

 

2. Kev Npaj Txoj Kev Tu: Tsis txhob muaj qhov pitfalls ntawm Unidirectional Scanning
Kev tu kom zoo ntawm txoj kev ua kom zoo dua qub: ua ntej ob txoj kev hla kev -scanning nrog txoj kev sib tshooj ntawm 30%-50%, tiv thaiv cov cheeb tsam uas ploj lawm thiab txo cov substrate puas; Ua haujlwm "txheej txheej" rau ntau txheej welds: nto spatter (5-7kW / cm²) → interlayer oxide nplai (8-10kW / cm²) → nto polishing (3-4kW / cm²).

 

3. Environmental and Auxiliary Technologies: Ua kom muaj kev ruaj ntseg thiab ruaj khov
Cov ntsiab lus yooj yim overlooked nyob rau hauv industrial chaw ncaj qha cuam tshuam qhov sib xws:
Inert Gas Protection: Thaum ntxuav stainless hlau thiab titanium alloys, siv cov roj argon ntawm tus nqi ntws ntawm 5-8 L / min los tiv thaiv oxidation theem nrab.
Kev tshem tawm plua plav thiab ntsuas kub: Siv lub tshuab nqus plua plav tshem tawm qhov tsis zoo (tsis zoo siab tshaj lossis sib npaug ntawm -0.06 MPa) txhawm rau tiv thaiv cov plua plav los ntawm kev cuam tshuam nrog kev sib kis ntawm laser; Thaum lub sijhawm ua haujlwm tas mus li, xyuas kom lub substrate kub tsawg dua lossis sib npaug li 200 degree, thiab qhib hom sib cuam tshuam yog tias qhov kub siab tshaj qhov pib.

 

 

Tej teeb meem thiab cov tswv yim daws teeb meem:
Residual Oxide Scale: Kho qhov chaw txoj kab uas hla thiab scanning ntau yam kom ntseeg tau tias cov npoo npoo npoo; tshwj xeeb nce lub zog ceev los ntawm 5% -10% kom ncav cuag oxide txheej txheej pib.
Substrate Micro-melting Marks: Feem ntau tshwm sim los ntawm pulses uas luv dhau los yog scanning qeeb dhau. Ntxiv cov mem tes dav los ntawm 20% -30% thiab ua kom nrawm nrawm rau 100-150 mm / s.
Tsawg dua - dua li - Kev Ua Tau Zoo: Tshawb xyuas lub wavelength thiab cov khoom sib txuam (infrared laser efficiency poob li 50% rau aluminium alloys); hloov unidirectional scanning rau bidirectional hla-scanning.

 

 

Kev lag luam daim ntawv thov Trends: Intelligentization + Customization
SDQY Laser's weld cleaning thev naus laus zis tau hloov kho dua tshiab rau "kev txawj ntse + kev hloov kho": nruab nrog lub zeem muag pom qhov system, nws cia li txheeb xyuas txoj haujlwm thiab qhov dav ntawm qhov vuam, thiab paub txog qhov tiag - lub sijhawm hloov ntawm qhov chaw thiab lub zog; rau siab -kawg teb xws li nuclear fais fab thiab aerospace, nws tsim kho cov cuab yeej siv nrog adjustable mem tes zog kom tau raws li qhov siab -precision tu xav tau ntawm welds ntawm cov khoom sib txawv.
