Kubatanidza simbi mbiri kana kupfuura kuburikidza nekuisa kupisa. Kubatanidza kunowanzo sanganisira kupisa chinhu kusvika pakunyunguduka kwacho kuitira kuti simbi yekutanga inyunguduke kuzadza mipata iri pakati pemajoini, zvichiita kuti pave nekubatana kwakasimba. Kubatanidza nelaser inzira yekubatanidza inoshandisa laser senzvimbo yekupisa.
Semuenzaniso, bhatiri remagetsi re square case: bhatiri rakabatana ne laser kuburikidza nezvikamu zvakawanda. Munguva yese ye laser welding, simba rekubatanidza zvinhu, kushanda zvakanaka kwekugadzira, uye mwero wakakanganisika zvinhu zvitatu zvinonyanya kutariswa neindasitiri. Simba rekubatanidza zvinhu rinogona kuratidzwa nekudzika kwekupinda kwe metallographic uye upamhi (zvakabatana zvakanyanya ne laser light source); kushanda zvakanaka kwekugadzira kunonyanya kuenderana nekugona kwekugadzirisa kwe laser light source; mwero wakakanganisika unonyanya kuenderana nekusarudza kwe laser light source; saka, chinyorwa chino chinokurukura zvakajairika pamusika. Kuenzanisa kuri nyore kwemavara akati wandei e laser light sources kunoitwa, tichitarisira kubatsira vamwe vanogadzira ma process.
Nekutiwelding nelaserChaizvoizvo inzira yekushandura chiedza kubva pakupisa kuenda kuchiedza, zvinhu zvakakosha zvakawanda zvinobatanidzwa ndeizvi: mhando yemwaranzi (BBP, M2, divergence angle), simba rakawanda, dhayamita yepakati, fomu yekugovera simba, musoro we welding unochinjika, mahwindo ekugadzirisa uye zvinhu zvinogadziriswa zvinonyanya kushandiswa kuongorora nekuenzanisa masosi echiedza chelaser kubva kunzira idzi.
Kuenzanisa kweLaser yeSinglemode-Multimode
Tsanangudzo yemhando dzakasiyana dzemhando dzakasiyana:
Nzira imwe chete inoreva nzira imwe chete yekugovera simba relaser mundege ine mativi maviri, nepo nzira dzakawanda dzichireva nzira yekugovera simba respatial inoumbwa nekuiswa kwemapatani akawanda ekugovera. Kazhinji, saizi yemhando yebeam M2 factor inogona kushandiswa kutonga kana fiber laser inobuda iri nzira imwe chete kana kuti nzira dzakawanda: M2 iri pasi pe1.3 ilaser yakachena yemodhi imwe chete, M2 iri pakati pe1.3 ne2.0 ilaser yemodhi imwe chete (shoma), uye M2 yakakura kupfuura 2.0. Kune malaser emodhi dzakawanda.

Sezvakaratidzwa pamufananidzo: Mufananidzo b unoratidza kugoverwa kwesimba kwemodhi imwe chete, uye kugoverwa kwesimba chero kupi zvako kunopfuura nepakati pedenderedzwa kuri muchimiro chegoko reGaussian. Mufananidzo a unoratidza kugoverwa kwesimba remamodhi akawanda, inova kugoverwa kwesimba renzvimbo kunoumbwa ne superposition yemamodhi akawanda elaser imwe chete. Mhedzisiro ye multi-mode superposition igoko rakatsetseka.
MaLaser akajairika emodhi imwe chete: IPG YLR-2000-SM, SM ipfupiso yeSingle Mode. Maverengero anoshandisa collimated focus 150-250 kuverenga saizi yenzvimbo yekutarisa, huwandu hwesimba i2000W, uye huwandu hwesimba rekutarisa hunoshandiswa kuenzanisa.
Kuenzanisa kwemodhi imwe chete nemodhi dzakawandawelding nelasermigumisiro
Laser yemhando imwe chete: dhayamita diki yepakati, huwandu hwesimba rakawanda, kugona kupinda kwakasimba, nzvimbo diki inokanganiswa nekupisa, yakafanana nebanga rakapinza, inonyanya kukodzera kusanganisa maplate matete uye kusanganisa nekukurumidza, uye inogona kushandiswa nemagalvanometers kugadzirisa zvikamu zvidiki uye zvikamu zvinopenya zvakanyanya (zvikamu zvinopenya zvakanyanya) nzeve, zvidimbu zvinobatanidza, nezvimwewo), sezvakaratidzwa mumufananidzo uri pamusoro, single-mode ine gomba diki rekiyi uye huwandu hushoma hwehutsi hwesimbi hwemukati hune simba rakawanda, saka kazhinji haina zvikanganiso zvakaita semaburi emukati. Pakumhanya kwakaderera, chitarisiko chayo chakaoma pasina kuputira mhepo inodzivirira. Pakumhanya kwakakwirira, dziviriro inowedzerwa. Hunhu hwekugadzirisa gasi hwakanaka, kushanda kwacho kwakanyanya, ma welds akapfava uye akatsetseka, uye mwero wekubudirira wakakwira. Yakakodzera kusanganisa stack uye kusanganisa kupinda.
Laser ine maitiro akawanda: Dhayamita yakakura yepakati, simba rakaderera zvishoma pane laser ine maitiro maviri, banga risina kujeka, gomba guru rekiyi, chimiro chesimbi chakakora, chiyero chidiki chekudzika kusvika paupamhi, uye nesimba rimwe chete, kudzika kwekupinda kwakaderera ne30% pane kwe laser ine maitiro maviri, saka yakakodzera kushandiswa. Yakakodzera kugadziriswa kwebutt weld uye kugadziriswa kweplate gobvu ine mipata mikuru yekuunganidza.
Kusiyana kweLaser neComposite-Ring
Kusonta kweHybrid: Danda re semiconductor laser rine urefu hwe 915nm uye danda re fiber laser rine urefu hwe 1070nm zvakabatanidzwa mumusoro mumwe chete wekusonta. Matanda maviri e laser akapararira pamwe chete uye nzvimbo dzinotarisana dzemadanda maviri e laser dzinogona kugadziriswa nenzira inochinjika, kuitira kuti chigadzirwa chive ne ese ari maviri e semiconductor.welding nelaserkugona mushure mekunamira. Mhedzisiro yacho yakajeka uye ine kudzika kwefiberwelding nelaser.
MaSemiconductor anowanzo shandisa nzvimbo yakakura yechiedza inodarika 400um, iyo inonyanya kukonzera kupisa kwechinhu, kunyungudutsa pamusoro pechinhu, uye kuwedzera mwero wekunyungudutswa kwefiber laser yechinhu (mwero wekunyudzwa kwelaser yechinhu unowedzera sezvo tembiricha ichiwedzera)
Ring laser: Mamodule maviri efiber laser anoburitsa chiedza chelaser, icho chinopfuudzwa pamusoro pechinhu kuburikidza necomposite optical fiber (ring optical fiber mukati me cylindrical optical fiber).
Matanda maviri elaser ane annular spot: rin'i yekunze ndiyo inokonzera kuwedzera kuvhurwa kwekiyi nekunyungudutsa zvinhu, uye laser yemukati ndiyo inokonzera kudzika kwekupinda, zvichiita kuti spatter welding ive yakaderera zvikuru. Madhayamita emukati melaser yemukati neyekunze anogona kuenzaniswa zvakasununguka, uye dhayamita yemukati inogona kuenzaniswa zvakasununguka. Hwindo rekugadzirisa rinochinjika zviri nani kupfuura riya relaser beam rimwe chete.
Kuenzanisa kwemigumisiro yekukwevera kwesimbi yakasanganiswa-yakatenderera
Sezvo welding yehybrid iri musanganiswa we semiconductor thermal conductivity welding uye fiber optic deep penetration welding, kupinda kwering yekunze hakuna kudzika, chimiro che metallographic chakapinza uye chakatetepa; panguva imwe chete, chitarisiko chacho ndechekufambisa kwekupisa, dziva rakanyungudutswa rine kuchinja kudiki, nzvimbo yakakura, uye dziva rakanyungudutswa rakagadzikana, richiratidza chitarisiko chakapfava.
Sezvo ring laser iri musanganiswa we deep penetration welding uye deep penetration welding, ring yekunze inogonawo kugadzira kudzika kwe penetration, izvo zvinogona kuwedzera kuvhura keyhole. Simba rimwe chete rine kudzika kukuru kwe penetration uye metallography yakakora, asi panguva imwe chete, kugadzikana kwedziva rakanyungudutswa kwakaderera zvishoma pane. Kuchinja-chinja kwe optical fiber semiconductor kwakakura zvishoma pane kwe composite welding, uye roughness yakakura.
