Qhov zoo ntawm laser welds yog nyob ntawm ntau yam welding tsis muaj peev xwm tswj tau zoo kom ua tiav cov txiaj ntsig zoo. Tsab ntawv xov xwm no delves rau hauv qhov tseem ceeb tsis cuam tshuam rau qhov zoo ntawm qhov vuam hauv cov txheej txheem laser vuam, txhawb nqa los ntawm cov ntaub ntawv thiab kev nkag siab rau lawv cov kev cuam tshuam thiab cov tswv yim zoo.
Laser Vuam yog dab tsi?
Laser vuam siv lub teeb tsom teeb pom kev sib koom ua ke kom yaj thiab koom nrog cov hlau ua ke nrog cov cheeb tsam uas muaj cua sov tsawg (HAZ) piv rau cov txheej txheem vuam tsoos. Cov txheej txheem no yog tus cwj pwm los ntawm nws lub peev xwm los ua kom muaj kev sib sib zog nqus tob, siab vuam ceev, thiab kev tswj xyuas meej ntawm cov yam ntxwv weld. Lub ntsiab tseem ceeb ntawm kev siv cov txiaj ntsig zoo no yog kev tswj xyuas qhov zoo ntawm cov khoom siv vuam, uas cuam tshuam ncaj qha rau kev ncaj ncees thiab qhov zoo ntawm qhov sib koom ua ke.
Cov tsis tseem ceeb cuam tshuam rau Weld Quality
Lub zog ceev thiab lub zog nkag:Lub zog ntom ntom, txiav txim siab los ntawm lub zog laser thiab kab teeb kab, txiav txim siab cov cua sov siv rau ib cheeb tsam. Lub zog muaj zog ntau dua ua rau kev nkag mus tob dua tab sis yuav tsum sib npaug kom tsis txhob muaj ntau dhau los yog tawg. Lub zog tawm tswv yim (lub zog ceev × lub sijhawm) cuam tshuam cov pas dej ua ke ruaj khov thiab cov hlaws morphology, tseem ceeb heev rau kev tswj qhov dav thiab qhov tob.
Wavelength thiab Absorption yam ntxwv:Lub wavelength ntawm lub laser beam cuam tshuam nws kev cuam tshuam nrog cov khoom. luv luv wavelengths (piv txwv li, fiber ntau lasers ntawm ~ 1 μm) yog zoo-absorbed los ntawm hlau xws li hlau thiab txhuas, txhawb zog npaum hloov mus rau hauv thiab sib sib zog nqus. Ntev wavelengths (piv txwv li, CO2 lasers ntawm ~ 10.6 μm) yog tsim rau cov hlau tsis muaj hlau thiab qee cov hlau xws li tooj liab, cuam tshuam cov txheej txheem kev ua haujlwm thiab kev faib hluav taws xob.
Beam Focus thiab Quality:Qhov tsom pom qhov loj me thiab kab teeb pom kev zoo (M² yam) txiav txim siab lub peev xwm los mloog zoo zog thiab tuav lub pas dej ua ke ruaj khov. Ib txoj kab me me, ua kom pom tseeb zoo txhim kho qhov tseeb thiab txo qis cov cua sov dispersion, tseem ceeb heev rau kev siv vuam zoo uas yuav tsum tau ua kom nruj nruj thiab tsis sib haum xeeb tsawg.
Travel Speed thiab Beam Delivery:Kev nrawm nrawm ncaj qha cuam tshuam rau cov khoom siv hluav taws xob thiab cov cua txias, cuam tshuam rau microstructure thiab mechanical zog ntawm weld. Kev tswj xyuas meej ntawm cov kab xaim xaim (piv txwv li, galvanometer scanners rau fiber ntau lasers) ua kom lub zog sib npaug ntawm cov vuam seam, txo qhov tsis xws luag xws li porosity thiab tsis sib xws.
Shielding Gas thiab Atmosphere:Kev xaiv cov roj thaiv thaiv (xws li, argon, helium) thiab huab cua (xws li, inert, reactive) nyob ib ncig ntawm thaj chaw weld plays lub luag haujlwm tseem ceeb hauv kev tiv thaiv lub pas dej molten los ntawm oxidation thiab paug. Cov pa roj kom zoo thiab kev faib tawm ua kom zoo dua cov hlaws zoo li cov hlaws thiab metallurgical kev ncaj ncees, tshwj xeeb tshaj yog hauv cov hlau reactive lossis cov ntawv thov tseem ceeb.
