Laser cladding tau dhau los ua lub hauv paus thev naus laus zis hauv kev tsim khoom niaj hnub, tshwj xeeb hauv kev lag luam xws li kev tiv thaiv, tshuab hnyav, thiab aerospace- qhov twg precision, durability, thiab cov txheej txheem stability tsis yog - sib tham. Ib qho tseem ceeb feem cuam tshuam ncaj qha rau qhov zoo ntawmLaser CladdingCov txiaj ntsig yog ob -xim pyrometer, tsis yog- ntsuas qhov ntsuas kub uas ua kom muaj kev tswj xyuas qhov kub thiab txias thaum lub sijhawm txheej txheem cladding. Xaiv txoj cai ob -xim pyrometer rau koj cov khoom siv laser cladding tsis yog ib qho - loj- haum- txhua txoj haujlwm; nws yuav tsum tau ua tib zoo xav txog cov tsis, compatibility, installation, thiab ntev - tu ncua sij hawm. Hauv blog no, peb rhuav tshem cov ntsiab lus tseem ceeb los pab koj xaiv ob -xim pyrometer uas sib txuas nrog koj lub laser cladding system, ua kom cov txheej txheem ua haujlwm zoo, thiab txo qhov tsis xws luag.
Core Parameters xaiv qhov tsim nyog Ob -xim Pyrometer rau Laser Cladding
Kev ua tau zoo ntawm ob -xim pyrometer hauvLaser Claddingnyob ntawm nws qhov tseem ceeb tsis, uas yuav tsum ua raws li cov kev cai tshwj xeeb ntawm koj cov txheej txheem cladding. Ua ntej thiab qhov tseem ceeb tshaj plaws, qhov kub thiab txias yog qhov tseem ceeb: laser cladding feem ntau ua haujlwm ntawm qhov kub ntawm 800℃thiab 2500 degree, yog li koj lub pyrometer yuav tsum npog qhov ntau yam no kom paub meej qhov ntsuas qhov tseeb thoob plaws txhua theem ntawm cov txheej txheem. Tsis txhob siv cov pyrometers nrog qhov ntsuas qhov nqaim, vim tias lawv yuav tsis tuaj yeem ntes qhov kub hloov pauv thaum lub sij hawm alloy melting thiab solidification.
Tom ntej no, wavelength range ncaj qha cuam tshuam qhov ntsuas qhov tseeb, tshwj xeeb tshaj yog thaum cuam tshuam nrog cov ntaub ntawv sib txawv (xws li, carbon steel, alloy steel, nickel{2}}raws li alloys). Ob -xim pyrometers siv ob qhov sib txawv wavelengths los xam qhov kub thiab txias, yog li xaiv tus qauv nrog wavelengths sib haum nrog koj cov ntaub ntawv lub hom phiaj-piv txwv li, luv wavelengths (1.0–1.6 μm) ua haujlwm zoo rau siab - kub alloys, thaum lub wavelengths ntev (2.0–5.0. Tsis tas li ntawd, kev hloov pauv emissivity yog qhov tseem ceeb: laser cladding nto muaj qhov sib txawv emissivity thaum lub sij hawm tus txheej txheem, yog li ib tug pyrometer nrog adjustable emissivity nqis yuav xyuas kom meej raws li qhov tseeb txawm raws li qhov saum npoo tej yam kev mob hloov.
Lwm qhov tseem ceeb tsis muaj xws li lub sij hawm teb (xav tau cov qauv nrog lub sij hawm teb tsawg dua los yog sib npaug li 10 ms kom ntes tau tiag -lub sij hawm kub hloov pauv) thiab ntsuas qhov chaw loj (muab qhov chaw me me rau thaj tsam cladding- me me rau qhov meej, thaj chaw cladding, qhov chaw loj dua rau qhov chaw dav). Kev saib xyuas cov kev ntsuas no tuaj yeem ua rau qhov ntsuas kub tsis raug, ua rau muaj qhov tsis xws luag xws li tawg, porosity, lossis txheej tsis sib xws.
Installation Position thiab Calibration Skills for Pyrometer-Laser Linkage
Txawm tias ob qhov zoo tshaj plaws -xim pyrometer yuav underperform yog tias ntsia tsis raug los yog tsis calibrated kom zoo-tshwj xeeb tshaj yog thaum txuas nrogLaser Claddingkhoom siv. Lub installation txoj hauj lwm yuav tsum xyuas kom meej ib tug unobstructed saib ntawm lub cladding cheeb tsam, tsis txhob cuam tshuam los ntawm laser tawg, spatter, los yog pa luam yeeb. Mount lub pyrometer ntawm lub kaum sab xis ntawm 30-45℃txheeb ze rau lub ntsej muag cladding kom tsis txhob muaj kev cuam tshuam ncaj qha ntawm lub laser beam, uas tuaj yeem skew kub nyeem ntawv. Tsis tas li ntawd, tso lub pyrometer ze txaus rau thaj tsam cladding kom tswj qhov ntsuas qhov tseeb, tab sis deb txaus los tiv thaiv kev puas tsuaj los ntawm tshav kub lossis tawg.
Calibration yog qhov tseem ceeb sib npaug rau cov pyrometer txhim khu kev qha -laser linkage. Ua ntej pib siv, calibrate lub pyrometer siv tus txheej txheem kub qhov chaw (xws li, ib tug blackbody rauv) uas phim lub cladding kub ntau yam. Rau qhov tsis tu ncua, rov kho cov pyrometer txhua 3-6 lub hlis, lossis thaum twg koj hloov cov ntaub ntawv cladding lossis cov txheej txheem tsis ua haujlwm. Thaum calibrating, xyuas kom cov khoom siv laser cladding nyob rau hauv lub xeev ruaj khov (xws li, lub zog laser zoo ib yam, tus nqi noj tsis tu ncua) kom ua raws li kev ua haujlwm tiag tiag. Kev ntsuas kom zoo ua kom paub tseeb tias cov pyrometer qhov kub thiab txias cov ntaub ntawv yog qhov tseeb, tso cai rau kev kaw zoo - voj tswj nrog lub laser cladding system.
Compatibility ntawm Pyrometer nrog Fiber Laser Cladding Tshuab thiab Neeg Hlau
Hauv kev ua haujlwm niaj hnub laser cladding, feem ntau cov tshuab tau ua ke nrog fiber ntau laser cladding machines thiab muaj neeg hlau rau automation thiab precision. Thaum xaiv ob -xim pyrometer, kev sib raug zoo nrog cov khoom no tsis yog - sib tham. Ua ntej, xyuas covkev sib txuas lus raws tu qauv:lub pyrometer yuav tsum txhawb nqa cov txheej txheem kev lag luam (xws li Modbus, Profinet, Ethernet / IP) kom seamlessly txuas nrogLaser Claddingtshuab tswj qhov system thiab neeg hlau. Qhov no tso cai rau kev xa tawm cov ntaub ntawv lub sijhawm tiag tiag, ua rau lub laser kho lub zog, nrawm, lossis pub tus nqi tau txais los ntawm pyrometer qhov ntsuas kub nyeem.
Tsis tas li ntawd, xav txog cov pyrometer'smechanical compatibilitynrog neeg hlau caj npab los yog laser taub hau. Saib rau cov qauv me me, lub teeb yuag pyrometer uas tuaj yeem ntsia tau rau ntawm caj npab neeg hlau yam tsis muaj kev cuam tshuam nrog cladding txav. Qee cov pyrometers yog tsim los nrog hloov tau yooj yim mounting brackets, ua kom yooj yim rau kev koom ua ke nrog kev sib txawv laser cladding setups - txawm nyob ruaj ruaj los yog neeg hlau. Nws tseem yog ib qho tseem ceeb kom ntseeg tau tias lub pyrometer tuaj yeem tiv taus qhov hnyav ntawm laser cladding, nrog rau qhov kub thiab txias, plua plav, thiab kev co, kom tsis txhob muaj kev puas tsuaj ntau zaus.
Tom qab -muag Debugging thiab Ntev - Lub Sijhawm Stability Maintenance of Linked System
Thaum koj tau xaiv thiab ntsia ob -xim pyrometer, tsim nyog tom qab- muag debugging thiab ntev- tu ncua sij hawm yog qhov tseem ceeb rau kev ruaj ntseg ntawm pyrometer-Laser Claddingkev sib txuas. Ua haujlwm nrog koj tus neeg muag khoom pyrometer los ua -qhov chaw debugging, uas suav nrog kev sim kev sib txuas lus ntawm pyrometer, laser tshuab, thiab neeg hlau, txheeb xyuas qhov tseeb ntawm qhov kub thiab txias, thiab ua kom zoo kaw -loop tswj qhov ntsuas. Cov kauj ruam no ua kom ntseeg tau tias tag nrho cov kab ke ua haujlwm hauv sync, txo qhov kev pheej hmoo ntawm cov txheej txheem yuam kev
Rau ntev - kev tu ncua sij hawm, tsim ib lub sij hawm tsis tu ncua los ntxuav lub pyrometer lub lens - laser cladding spatter thiab pa luam yeeb tuaj yeem sau rau ntawm lub lens, txo qhov ntsuas qhov tseeb. Siv cov ntaub mos mos, lint -dawb ntaub thiab tshuaj ntxuav tshwj xeeb kom tsis txhob khawb lub lens. Tsis tas li ntawd, tshuaj xyuas cov pyrometer txoj hlua thiab kev sib txuas tsis tu ncua kom tsis txhob muaj teeb liab poob lossis cuam tshuam. Khaws cov ntaub ntawv teev hnub ntsuas, kev saib xyuas kev ua ub no, thiab txhua yam teeb meem kev ua haujlwm, vim qhov no yuav pab txheeb xyuas cov teeb meem tshwm sim thaum ntxov thiab ncua lub pyrometer lub neej.
Thaum kawg, xaiv tus neeg muag khoom uas muaj kev ntseeg siab tom qab- kev txhawb nqa muag, suav nrog kev pab cuam, khoom seem, thiab cov kev pabcuam kho. Thaum muaj kev ua haujlwm tsis zoo, kev txhawb nqa tam sim yuav txo qis qis thiab ua kom koj cov haujlwm laser cladding tuaj yeem rov pib sai.
Xaiv txoj cai ob -xim pyrometer rau koj cov khoom siv laser cladding yog qhov kev txiav txim siab tseem ceeb uas cuam tshuam ncaj qha rau cov txheej txheem zoo, kev ua tau zoo, thiab tus nqi -kev ua tau zoo. Los ntawm kev tsom mus rau cov ntsiab lus tseem ceeb, kev teeb tsa thiab kev ntsuas kom zoo, kev sib raug zoo nrog koj cov kab ke uas twb muaj lawm, thiab kev saib xyuas lub sijhawm ntev, koj tuaj yeem xaiv lub pyrometer uas sib txuas nrog koj cov khoom siv laser cladding, muab kev tswj kub zoo ib yam, thiab pab koj ua tiav siab -cov txiaj ntsig zoo cladding. Nyob rau hauv ib lub sijhawm uas qhov tseeb thiab kev ntseeg siab yog qhov tseem ceeb, qhov zoo - sib luag ob - xim pyrometer yog kev nqis peev uas them nyiaj rau hauv kev txo qis, txhim kho cov khoom tsim tau, thiab ntev - lub sijhawm ua haujlwm ruaj khov.
