Laser welding hauv tooj liab vuam, thawj qhov kev xav yog cov khoom siv rau qhov nqus laser. Thaum 1060nm (CO2 laser) laser wavelength, qhov nqus tus nqi ntawm tooj liab rau laser tsuas yog li 10%. Hauv qhov ntau ntawm laser laser ntev ntev ntawm 500nm, qhov nqus ntawm tooj mus rau laser yog qhov siab dua, thiab cov thev naus laus zis tsis tuaj yeem nkag mus tob tob. Txawm li cas los xij, thaum tooj liab nyob hauv lub xeev melting, qhov nqus ntawm laser tuaj yeem ncav cuag qhov siab dua, yog li siv cov khoom siv hluav taws xob muaj zog-lub xeev laser kom ua tiav lub qhov tawg tawg tuaj yeem ua rau laser vuam tooj liab tau.
Laser vuam cov phiaj xwm
Raws li pom hauv daim duab, cov qauv sib txuas ntawm laser vuam siv yog siv lub taub hau laser kom phim rau cov cim ua kom pom tau zoo. Lub taub hau laser yuav tsum yog lub kaw lus galvanometer nrog ob qhov ntev ntawm X thiab y, uas tuaj yeem paub txog cov vuam khiav ntawm ntau cov duab ntawm vuam dav hlau. Tsis tas li ntawd, nws tseem yuav tsum muaj qhov muaj peev xwm ntau qhov oscillation muaj nuj nqi, uas tuaj yeem nplawm lub pas dej nyob rau hauv lub vuam txheej txheem, uas yog qhov tsim nyog rau cov roj tawm hauv qhov dej pas nrig thiab ua kom zoo dua vuam zoo. Lub zeem muag pom kev tsim kho yuav tsum muaj peev xwm paub txog cov duab ntawm ntau cov leeg txuas pob txha, thiab kuj yuav tsum muaj qee qhov tsis ua yuam kev tsis haum.
