Yuav daws qhov teeb meem li cas thaum lub sij hawm Laser Vuam Tshuab Vuam?

Spatter yog ib qho teeb meem tseem ceeb hauv laser vuam. Txhais raws li qhov ejection ntawm molten hlau droplets los ntawm lub pas dej ua ke, spatter tsis tsuas yog mars nto tsos, tab sis kuj tuaj yeem ua raws li cov khoom siv kho qhov muag, nce tus nqi tu thiab ua rau muaj kev puas tsuaj mus tas li. Txhawm rau tshem tawm lossis txo qis qis, yuav tsum muaj kev sib koom ua ke ntawm cov txheej txheem, txheej txheem, kev npaj cov khoom siv, thiab cov roj thaiv kev tiv thaiv.

1. Parameter Optimization

 

a. Lub zog vs. Ceev  

Lub zog laser ntau dhau yog thawj tus tsav tsheb sib tsoo. Thaum lub hwj chim dhau ntawm cov khoom siv lub peev xwm nqus tau, vaporization sai ua rau lub zog rov ua kom rov qab muaj zog uas ejects droplets. Nyob rau hauv aluminium vuam, piv txwv li, lub zog siab ua rau qis-boiling-point magnesium kom vaporize sai sai, ua rau tawg loj heev. Kev nrawm nrawm yog sib npaug sib npaug: nrawm dhau ua rau lub sijhawm sib cuam tshuam, tsom lub zog hauv zos thiab ua rau muaj vaporization sai; qeeb dhau ntxiv cov cua sov ntau dhau, rov ua rau spatter. Rau cov ntawv nyias nyias, txo hwj chim thiab nce ceev; rau daim hlau tuab, tsa lub zog judiciously thaum tuning ceev kom muaj kev nkag mus yam tsis muaj overheating.

b. Defocus Kho  

Defocus ho hloov lub zog faib ntawm lub workpiece. Me me zoo defocus enlarge qhov chaw thiab txo qis qhov siab tshaj plaws, tiv thaiv overheating thiab spatter. Kev sim sim ntawm nyias cov ntawv ci stainless qhia tau hais tias xaiv qhov tseeb qhov zoo defocus nrug tuaj yeem txiav cov xwm txheej tshwm sim yuav luag ib nrab thaum tswj xyuas kev ncaj ncees.

2. Kev txhim kho txheej txheem

a. Ramp-Up / Ramp-down Control  

Spatter nquag pib ntawm arc pib thiab txiav cov ntsiab lus uas lub zog hloov pauv sai. Ua raws li kev tswj hwm lub hwj chim ramp - maj mam nce mus rau qhov chaw teeb tsa thaum pib thiab tawm ntawm qhov kawg - zam kev poob siab thermal. Hauv kev tsim cov khoom siv tsheb, qhov muag muag-pib / mos-stop logic tau txo qhov pib- thiab qhov kawg-point spatter los ntawm> 30%, txhim kho tag nrho cov seam zoo.

b. Joint Design & Fit-Up  

Kev sib koom ua ke tsis zoo lossis qhov sib txawv ntau dhau ua rau lub zog nqus tsis sib xws thiab yaj-pool tsis ruaj khov. Qhov sib txawv uas dav dhau tso cai rau lub zog laser los ntawm, tsim kom tsis muaj kev tswj hwm yaj thiab tawg. Conversely, complex groove shapes yuav defocus lub beam. Tsim cov pob qij txha nrog zoo ib yam, nqaim qhov khoob thiab symmetrical grooves kom cov nqaj nruab nrab thiab lub pas dej ruaj khov.

3. Cov khoom siv tuav & tiv thaiv roj

a. Kev npaj nto  

Roj, xeb, thiab hmoov av vaporize los yog combust nyob rau hauv lub beam, generating siab spikes thiab spatter. Degrease nrog cov tshuaj ntxuav tes thiab tshem tawm cov oxide txheej los ntawm kev txhuam hniav los yog pickling. Cov chaw huv si tau pom tias yuav txo tau qhov tawg ntawm 40 - 60%.

b. Shielding Gas Xaiv & Flow  

High-purity argon los yog helium cais lub pas dej ua ke, suppresses oxidation, thiab tshuab tawm vapor thiab spatter. Tus nqi ntws yuav tsum sib phim rau cov khoom tuab thiab kev mus los nrawm: qis dhau los tiv thaiv lub pas dej; siab dhau cuam tshuam nws. Rau cov ntawv nyias, 8-12 L / min txaus; rau daim hlau tuab, 15-25 L / min yog qhov raug. Flow meters calibrated mus rau qhov tshwj xeeb nozzle thiab stand-off nrug kom zoo ib yam.

Xaus  

Spatter hauv laser vuam tuaj yeem tswj tau los ntawm kev ua kom zoo dua qhov tsis zoo, ua kom cov txheej txheem ua kom zoo dua qub, npaj cov khoom siv, thiab nplua-tuning shielding roj. Ntawm cov hom muaj, PDKJ welders excel nrog cov txheej txheem parameter-mapping, ruaj khov xa hluav taws xob, thiab kev saib xyuas tus neeg siv khoom-tag nrho cov pov thawj kom txo qis.

Txhawm rau pom PDKJ thev naus laus zis hauv kev nqis tes ua, mus ntsib peb ntawm EMO Hannover 2025, Cuaj Hlis 22–26, Hall 13, Stand F21. Muaj kev ua qauv qhia nyob, sab laj nrog peb cov kws ua haujlwm hauv daim ntawv thov, thiab qhib qhov muaj peev xwm tshiab rau kev vuam tsis zoo.
