Raws li kev tshawb fawb ntawm cov tshuab laser tsis siv neeg vuam tshuab, cov cim tseem ceeb rau kev txiav txim siab thiab ntsuas qhov zoo ntawm vuam tshuab yog qhov tob thiab dav ntawm vuam seam, qhov luaj li cas ntawm tshav kub cuam tshuam cheeb tsam, microstructure ntawm vuam seam, thiab kev ua tau zoo ntawm lub vuam seam. welded sib koom. Cov txheej txheem tsis cuam tshuam rau vuam zoo feem ntau suav nrog laser hom, lub zog, vuam ceev, focal txoj hauj lwm, plasma suppression, thiab lwm yam. Cov txheej txheem tsim nyog yog tus yuam sij kom ua tiav cov txiaj ntsig zoo. Niaj hnub no, peb yuav delve rau hauv yuav ua li cas laser hwj chim cuam tshuam lub vuam zoo ntawm tsis siv neeg laser vuam tshuab.
Txhawm rau kom nkag siab ntxiv txog kev cuam tshuam ntawm lub zog ntawm lub zog ntawm lub vuam zoo ntawm lub tshuab laser vuam tsis siv neeg, ntau qhov kev sim vuam tau ua, thiab kev sib raug zoo ntawm qhov tob thiab dav ntawm vuam seam thiab lub zog laser yog graphically sawv cev. Thaum lub zog laser yog qhov tsawg, qhov vuam nkag qhov tob yog qhov ntiav heev, tsawg dua 1 hli. Raws li lub zog nce, qhov nce hauv qhov tob tob kuj tseem qeeb. Nws tuaj yeem suav tau tias lub teeb lub zog nyob rau lub sijhawm no tsuas yog nqus los ntawm cov khoom nto, thiab laser vuam belongs rau thermal conduction vuam; Thaum lub zog laser nce mus txog 0.7 kW, lub zog laser siab ntom ntom ua rau lub qhov me me hauv cov hlau molten, ua tiav qhov sib sib zog nqus vuam; Tab sis thaum lub zog laser ntau tshaj 2.8 kW, nrog rau qhov nce ntawm lub zog, qhov nkag mus rau qhov tob yeej tsis nce, thaum qhov dav dav txuas ntxiv mus ntxiv. Yog vim li cas rau qhov no tej zaum yuav yog vim lub zog ceev ntawm lub tshuab laser vuam tsis siv neeg nce, cov plasma generated nyob rau hauv lub qhov me me nce, shielding lub laser beam tuaj thiab ua rau nws nyuaj rau lub zog laser mus txog rau hauv qab ntawm lub qhov. melting cov hlau, yog li tiv thaiv kev nkag mus tob ntawm kev nce.
Hauv cov ntsiab lus, ob qho tib si {{0}}.7kW thiab 28kW yog qhov faib cov ntsiab lus ntawm lub zog laser rau cov tshuab tsis siv neeg laser vuam. Thaum cov neeg yuav tsum tau siv cov cua sov conduction vuam, lub zog laser yuav tsum tau tswj hauv qab no 0.7kW; Thaum tib neeg yuav tsum siv qhov sib sib zog nqus nqus vuam, lub zog laser yuav tsum tau tswj ntawm 0.7 ~ 2.8 kW, txwv tsis pub nws yog qhov nyuaj los xyuas kom meej qhov zoo ntawm vuam.
