Cov txiaj ntsig kev sim qhia tau hais tias ntawm tib lub zog laser thiab zaus, qhov qis dua ntawm laser scanning ceev yog, qhov kev puas tsuaj ntau yog tshwm sim rau lub substrate.Thaum lub scanning ceev yog ntau tshaj ib tug tej yam nqi, qhov ceev ntawm scanning ceev, qhov phem cov xim txheej tshem tawm cov nyhuv.Kev sim cov txiaj ntsig ntawm kev ua haujlwm txuas ntxiv ntawm laser tu aluminium alloy nto xim txheej tsis nyiam rau 21 # (laser zog 200W, zaus 30kHz, scanning ceev 2000mm / s), ntxuav cov pa roj carbon steel nto xim txheej nyiam qhov ntsuas rau 37 # (laser zog 200W, zaus 30kHz, scanning ceev 3400mm / s).Ob qhov kev txwv no yuav tsis tsuas yog tshem tawm cov pa roj carbon steel nto xim txheej, thiab qhov kev puas tsuaj los ntawm cov qauv substrate kuj me me.

 

Xaus

Kev ntsuam xyuas tau pom tias ob qho tib si txuas ntxiv thiab cov lasers tuaj yeem tshem tawm cov xim ntawm cov khoom nto kom ua tiav cov txiaj ntsig tu.Nyob rau hauv tib lub hwj chim tej yam kev mob, lub efficiency ntawm pulsed laser tu yog ntau ntau dua li ntawm tas mus li lasers, thaum pulsed lasers yuav zoo dua tswj lub tshav kub input los tiv thaiv ntau substrate kub los yog microfusion.

Nruam lasers muaj qhov zoo dua ntawm tus nqi thiab tuaj yeem ua qhov sib txawv ntawm kev ua haujlwm nrog cov lasers los ntawm kev siv lub zog lasers, tab sis cov cua kub ntawm lub teeb hluav taws xob txuas ntxiv yog ntau dua thiab qhov kev puas tsuaj rau lub substrate nce.Yog li ntawd, muaj qhov sib txawv ntawm ob qho tib si hauv kev siv scenarios.Daim ntawv thov scenarios nrog siab precision, yuav tsum nruj tswj ntawm substrate kub nce thiab yuav tsum tsis txhob muaj kev puas tsuaj rau lub substrate, xws li pwm, yog pom zoo kom xaiv pulsed lasers.Rau qee cov qauv hlau loj, cov kav dej, thiab lwm yam, vim qhov loj ntawm cov cua kub dissipation ceev, cov substrate puas yuav tsum tsis siab, ces koj tuaj yeem xaiv cov lasers txuas ntxiv.
