Laser welder yog dab tsi thiab nws ua haujlwm li cas?

Laser Vuam ua haujlwm li cas

Laser vuam siv cov ntsiab lus kub kom yaj thiab fuse cov ntaub ntawv ntawm qhov sib koom ua ke:

• Txheej txheem : Lub laser beam xa cov khaus, tsom lub zog rau thaj tsam me me, tsim kom muaj lub pas dej ua ke uas ua rau muaj kev sib raug zoo.

• Keyhole Effect : Nyob ntawm lub zog txaus, cov nqaj vaporizes cov ntaub ntawv los tsim ib 'keyhole' - vapor kab noj hniav uas ua rau kom tob nkag mus thiab stabilizes lub pas dej ua ke.

• Precision Advantage : Tsawg tshav kub sib kis txo qhov cuam tshuam thiab khaws cov khoom siv

Cov yam ntxwv tseem ceeb : Wavelength, lub zog, thiab kev tsom xam txiav txim siab qhov tob tob thiab cov yam ntxwv ntawm vuam

Laser Hom rau Vuam
