Laser welding muchinayakatsvakwa kubva pakazvarwa lasers muma1960s.Yakasangana nemakore anoda kusvika makumi mana ebudiriro kubva pakunyungudutswa kwezvikamu zvidiki zvidiki kana michina kusvika kune yazvino yakakura-mwero kushandiswa kwepamusoro-simba laser welding mukugadzirwa kwemaindasitiri.Yakadzidzwa zvakajeka mukutanga kwezana remakore rechi20.Laser yekutanga yakagadziridzwa muna 1960. Makore mana gare gare, yekutanga pasi rose YAG solid-state laser uye CO2 gasi laser dzakagadzirwa.Kubva ipapo, laser welding michina yakashandiswa zvakanyanya mumhando dzakasiyana dzemaindasitiri.
1.ZvakanakiraLaser welding muchinazvichienzaniswa nemaitiro echinyakare welding
① Kusati kwauya kwelaser welding, indasitiri yemaindasitiri yanga ichishandisa nzira dzechinyakare dzekushongedza.Nekuda kwekusaenzana kwenzvimbo yekudziya uye kutonhora kweiyo weldment, post-weld deformation inowanzoitika, nekudaro kutadza kusangana nezvinodiwa zvewelding, uye nekuti iyo welding haina kunyatso kukwana, Pachavewo isina kukwana fusion pakati peworkpiece uye weld simbi kana. iyo weld layer, uye weld ine isiri-metallic slag, iyo inotora gasi uye inogadzira pores uye kumwe kukanganisa, izvo zvinowanzoita kuti zvikamu zvakashongedzwa zvitsemuka uye zvinokanganisa kuita kwekuvhara.
② Laser welding ine zvakanakira kusimba kwesimba, diki deformation, nhete-yakakanganiswa nzvimbo yekupisa, yakakwirira welding kumhanya, nyore otomatiki kudzora, uye hapana yekutevera kugadzirisa.Mumakore achangopfuura, yava nzira inokosha yesimbi yekugadzira zvinhu uye kugadzira.Zvichiwedzera kushandiswa zvakanyanya mumotokari, aerospace, indasitiri yekudzivirira, kuvaka ngarava, mainjiniya emugungwa, midziyo yemagetsi enyukireya uye mamwe minda, zvinhu zvinosanganisirwa zvinovhara zvinenge zvese zvesimbi.
③ Kunyangwe zvichienzaniswa nemaitiro echinyakare welding, laser welding ichine matambudziko emidziyo inodhura, hombe yenguva imwe chete yekudyara uye yakakwira tekinoroji zvinodiwa, izvo zvinoita kuti kushandiswa kwemaindasitiri kwelaser welding munyika yangu kuve kushoma, asi laser welding ine hunyanzvi hwekugadzira. zviri nyore kuona otomatiki Inodzorwa maficha anoita kuti ive yakanakira mitsara yekugadzira yakawanda uye inoshanduka kugadzira.
④ Parizvino, simbi welding ine yakakwira uye yepamusoro zvinodiwa zvekusimbisa simba uye chitarisiko.Iyo yechinyakare welding nzira inozokonzeresa matambudziko akadai sekukanganisa uye deformation yeworkpiece nekuda kwekupisa kwayo kukuru.Kuti ugadzirise dambudziko rekugadzirisa, nhamba huru yekutevera matanho anodiwa, zvichiita kuti kuwedzerwa kwemari.Iyo yakazara otomatiki laser welding nzira ine diki yekupisa yekuisa uye yakanyanya kudiki kupisa yakakanganisika nzvimbo, iyo inovandudza zvakanyanya kunaka kweiyo welded workpiece, inoderedza mutengo wekutevera webasa, uye inonatsiridza zvakanyanya kushanda kwewelding uye kugadzikana.
2.Different mienzaniso, zvakasiyana-siyana zvingasarudzwa
Muchidimbu, yazvino laser welding tekinoroji yakakura kwazvo.Laser welding michinakuva nekushandisa simba kwakaderera, kunyatsojeka, uye kusvibiswa kwezvakatipoteredza kushoma.Akawedzera tekinoroji maindasitiri ari kusarudza laser welding michina kuti ave nechokwadi chemhando yechigadzirwa uye kuvimbisa makambani nevatengi.
