Chii chinonzi laser welding?Laser Welding Yakatsanangurwa!Zvese zvaunoda kuti uzive nezve Laser Welding, kusanganisira kiyi musimboti uye main process paramita!
Vatengi vazhinji havanzwisisi iwo ekutanga misimboti yekushanda kwelaser welding muchina, rega kusarudza iyo chaiyo laser welding muchina, zvisinei Mimowork Laser iri pano kuti ikubatsire iwe kuita sarudzo chaiyo uye nekupa imwe tsigiro yekukubatsira iwe kunzwisisa laser welding.
Chii chinonzi Laser Welding?
Laser welding imhando yekunyunguduka welding, uchishandisa Laser danda senge welding kupisa sosi, iyo welding musimboti iri kuburikidza neimwe nzira yekukurudzira iyo inoshanda svikiro, ichigadzira resonant mhango oscillation, uye wozoshandura kuita inosimudzira nemwaranzi danda, kana danda. uye chidimbu chebasa chinosangana, simba rinotorwa nechidimbu chebasa, apo kutonhora kunosvika pakunyunguduka kwezvinhu zvinogona kuiswa.
Zvinoenderana neiyo huru nzira yewelding dziva, laser welding ine maviri ekutanga welding nzira: kupisa conduction welding uye yakadzika kupinda (keyhole) welding.Kupisa kunokonzerwa nekupisa conduction welding kunopararira kune basa kuburikidza nekupisa kwekushisa, kuitira kuti weld surface inyunguduke, hapana vaporization inofanira kuitika, iyo inowanzoshandiswa mukuputira kwepasi-speed thin-ish components.Yakadzika fusion welding inopfungaira zvinhu uye inoumba huwandu hukuru hweplasma.Nekuda kwekupisa kwakakwirira, pachava nemakomba kumberi kwedziva rakanyungudutswa.Yakadzika yekupinda welding ndiyo inonyanya kushandiswa laser welding mode, inogona weld basa racho zvakakwana, uye simba rekuisa rakakura, rinotungamira kukurumidza welding.
Maitiro Parameters muLaser Welding
Kune akawanda maitiro ma parameter anokanganisa kunaka kwelaser welding, senge simba density, laser pulse waveform, defocusing, welding kumhanya uye sarudzo yekubatsira kudzivirira gasi.
Laser Simba Density
Simba density ndeimwe yeakanyanya kukosha paramita mu laser processing.Nesimba repamusoro remagetsi, iyo yepamusoro layer inogona kudziyiswa kusvika painofashaira mukati memicrosecond, zvichikonzera kuwanda kwemhepo.Naizvozvo, iyo yakakwirira-simba density inobatsira pakubvisa zvinhu zvakadai sekuchera, kucheka uye kunyora.Nekuderera kwesimba remagetsi, zvinotora mamilliseconds akati wandei kuti tembiricha yepasi isvike panofashaira, uye nzvimbo isati yanyunguduka, pasi panosvika pakunyungudika, zviri nyore kuumba yakanaka kunyunguduka weld.Naizvozvo, muchimiro chekupisa conduction laser welding, iyo simba density range i104-106W/cm2.
Laser Pulse Waveform
Laser pulse waveform haingori yakakosha parameter yekusiyanisa kubviswa kwezvinhu kubva pakunyungudika kwezvinhu, asiwo yakakosha parameter kuona huwandu uye mutengo wekugadzirisa michina.Kana iyo yakakwirira intensity laser beam inopfurwa pamusoro pechinhu, pamusoro pechinhu chinenge chine 60 ~ 90% yelaser simba inoratidzwa uye inofungidzirwa kurasikirwa, kunyanya goridhe, sirivha, mhangura, aluminium, titanium uye zvimwe zvinhu zvine. kufungisisa kwakasimba uye kukurumidza kupisa kupisa.Kuratidzira kwesimbi kunosiyana nekufamba kwenguva panguva yelaser pulse.Kana tembiricha yepamusoro yechinhu ichikwira kusvika pakunyungudika, ratidziro inodzikira nekukurumidza, uye kana iyo nzvimbo iri mukunyunguduka, iyo ratidziro inodzikama pane imwe kukosha.
Laser Pulse Width
Pulse width ndiyo yakakosha parameter ye pulsed laser welding.Iyo pulse width yakatemwa nekudzika kwekupinda uye kupisa kwakakanganiswa nzvimbo.Iyo yakareba iyo pulse hupamhi hwaive, iyo yakakura kupisa kwakakanganiswa nzvimbo yaive, uye kudzika kwekupinda kwakawedzera neiyo 1/2 simba rekupuruzira hupamhi.Nekudaro, kuwedzera kwehupamhi hwekupuruzira kunoderedza simba repamusoro, saka kuwedzera kwehupamhi hwepurusi kunowanzo shandiswa pakupisa conduction welding, zvichikonzera saizi yakafara uye isina kudzika weld, kunyanya yakakodzera pamakumbo welding yemahwendefa matete uye akakora.Nekudaro, yakaderera peak simba inokonzeresa yakawandisa kupisa kupinza, uye chimwe nechimwe chinhu chine yakaringana pulse upamhi iyo inowedzera kudzika kwekupinda.
Defocus Quantity
Laser welding inowanzoda imwe chiyero chekudzikisira, nekuti simba density yenzvimbo yenzvimbo panzvimbo yelaser inotariswa yakawandisa, zviri nyore kuburitsa zvinhu zvewelding mumakomba.Kugoverwa kwesimba remagetsi kwakafanana mundege yega yega kure nelaser tarisiro.
Kune maviri defocus modes:
Positive uye yakaipa defocus.Kana iyo focal ndege iri pamusoro peiyo workpiece, yakanaka defocus;kana zvisina kudaro, iyo yakaipa defocus.Maererano geometric optics dzidziso, kana chinhambwe pakati yakanaka uye yakaipa defocusing ndege uye welding ndege akaenzana, simba density pamusoro rinoenderana ndege anenge zvakafanana, asi chaizvoizvo, akawanikwa yakanyungudutswa dziva chimiro zvakasiyana.Munyaya yedefocus yakaipa, kupindira kukuru kunogona kuwanikwa, iyo inobatana nekugadzirwa kwechidziva chakanyungudutswa.
Welding Speed
Welding kumhanya inosarudza welding pamusoro pemhando, kudzika kwekupinda, kupisa kwakakanganiswa nzvimbo uye zvichingodaro.Iyo welding yekumhanyisa ichakanganisa kupisa kwekuisa pane imwe unit nguva.Kana iyo welding yekumhanyisa ikanyanya kunonoka, kupisa kwekuisa kwakakwira zvakanyanya, zvichikonzera kuti workpiece inopisa.Kana iyo welding yekumhanyisa ichikurumidza, iyo yekupisa yekupinza ishoma, zvichikonzera kuti workpiece welding zvishoma uye isina kupera.Kuderedza welding kumhanya kunowanzoshandiswa kuvandudza kupinda.
Yekubatsira Blow Dziviriro Gasi
Yekuwedzera pfuti yekudzivirira gasi inzira yakakosha mune yakakwira simba laser welding.Kune rumwe rutivi, kudzivirira simbi zvinhu kubva kupfapfaidza uye kusvibisa girazi rinotarisa;Kune rimwe divi, ndeye kudzivirira iyo plasma inogadzirwa muwelding process kuti isatarise zvakanyanya uye kudzivirira laser kuti isasvike pamusoro pechinhu.Mukuita laser welding, helium, argon, nitrogen uye mamwe magasi anowanzoshandiswa kuchengetedza dziva rakanyungudutswa, kuitira kudzivirira workpiece kubva oxidation mune welding engineering.Zvinhu zvakadai serudzi rwegasi rinodzivirira, saizi yekuyerera kwemhepo uye kuvhuvhuta kweAngle zvine simba guru pamhedzisiro yewelding, uye nzira dzakasiyana dzekufuridza dzichavawo nekukanganisa kwemhando yewelding.
Yedu yakakurudzirwa Handheld Laser Welder:
Laser Welder - Nzvimbo Yekushanda
◾ Tembiricha yenzvimbo yekushanda: 15 ~ 35 ℃
◾ Humidity huwandu hwenzvimbo yekushanda: <70% Hapana condensation
◾ Kutonhora: kutonhora kwemvura kunodiwa nekuda kwebasa rekubvisa kupisa kwelaser kupisa-kubvisa zvinhu, kuve nechokwadi chekuti laser welder inomhanya zvakanaka.
(Yakadzama kushandiswa uye kutungamira nezve mvura chiller, unogona kutarisa:Kuomesa-kuvheneka Matanho eCO2 Laser System)
