Kev ncua deb ntawm ob qhov chaw welds nyob ntawm daim ntawv tuab thiab cov khoom siv. Qhov sib nrug me me ntawm ob qhov sib txuas ntawm qhov chaw welds yuav tsum tau zam kom ua tiav lub zog vuam zoo. Nws raug pom zoo tias qhov kev ncua deb ntawm ob qhov chaw welds yuav tsum yog yam tsawg kawg ntawm 10 npaug ntawm cov khoom tuab.
Yuav ua li cas yog cov theem ntawm qhov chaw vuam?
Txoj kab uas hla yog li ntawm 100 txog 800 μm nyob ntawm kab kab kab, cov khoom siv, thiab lub zog laser. Cov txheej txheem vuam qhov chaw tuaj yeem muab faib ua plaub theem: cua sov, melting, yaj ntws dynamics, thiab txias. Nyob ntawm qhov kev siv, evaporation ntawm cov khoom yuav tshwm sim.
Dab tsi thickness hlau yog qhov chaw vuam zoo tagnrho rau?
Spot vuam feem ntau yog siv rau kev sib koom ua ke uas yog ib txwm mus txog 3 hli hauvthickness. Thickness ntawm qhov yuav tsum tau welded yuav tsum sib npaug los yog qhov ratio ntawm thickness yuav tsum tsawg tshaj li 3: 1. Lub zog ntawm qhov sib koom ua ke nyob ntawm tus lej thiab qhov loj ntawm cov welds.
