Welding inzira yekubatanidza simbi mbiri kana kupfuura pamwechete kuburikidza nekuisa kupisa. Welding inowanzo sanganisira kupisa chinhu kusvika pakunyunguduka kwayo kuitira kuti simbi yepasi inyunguduke kuzadza maburi pakati pemajoini, ichigadzira kubatana kwakasimba. Laser welding inzira yekubatanidza inoshandisa laser senzvimbo yekupisa.
Tora iyo square kesi simba bhatiri semuenzaniso: iyo bhatiri musimboti wakabatanidzwa nelaser kuburikidza neakawanda zvikamu. Munguva yese yelaser welding process, simba rekubatanidza zvinhu, kugona kugadzira, uye chiyero chakakanganisika zvinhu zvitatu izvo indasitiri inonyanya kunetsekana nazvo. Simba rekubatanidza zvinhu rinogona kuratidzwa neiyo metallographic yekupinda kudzika uye hupamhi (padhuze neiyo laser light source); Kubudirira kwekugadzira kunonyanya kuenderana nekugadzirisa kugona kweiyo laser light source; chiyero chekuremara chinonyanya kuenderana nekusarudzwa kweiyo laser light source; saka, chinyorwa ichi chinokurukura zvakajairika pamusika. Kuenzanisa kwakapusa kweakati wandei laser mwenje masosi inoitwa, uchitarisira kubatsira vamwe magadzirirwo magadzirirwo.
Nokutilaser weldinginonyanya kutendeuka-ku-kupisa kutendeuka nzira, akati wandei akakosha ma paramita anosanganisirwa anotevera: danda remhando (BBP, M2, divergence angle), simba density, dhayamita yepakati, fomu rekugovera simba, adaptive welding musoro, process process windows uye zvinhu zvinogadziriswa. anonyanya kushandiswa kuongorora uye kuenzanisa laser mwenje masosi kubva kune aya mafambiro.
Singlemode-Multimode Laser Kuenzanisa
Tsanangudzo yeimwe-modhi yakawanda-modhi:
Single modhi inoreva imwechete yekugovera patani yelaser simba pane maviri-dimensional ndege, nepo akawanda-modhi ichireva spatial simba rekugovera pateni inoumbwa nepamusoro pematanho ekugovera akawanda. Kazhinji, saizi yemhando yemhando yeM2 chinhu inogona kushandiswa kutonga kana iyo fiber laser kubuda iri single-mode kana akawanda-modhi: M2 isingasviki 1.3 ndeye yakachena single-mode laser, M2 iri pakati pe1.3 uye 2.0 ndeye quasi- single-mode laser (vashoma-modhi), uye M2 yakakura kupfuura 2.0. Kune multimode lasers.

Sezvinoratidzwa mumufananidzo: Mufananidzo b unoratidza kugoverwa kwesimba kweimwe nzira yakakosha, uye kugovera kwesimba mune chero nzira inopfuura nepakati pedenderedzwa iri muchimiro cheGaussian curve. Mufananidzo a unoratidza iyo yakawanda-modhi yekugovera simba, inova nzvimbo yekugovera simba inoumbwa neiyo superposition yeakawanda single laser modes. Mhedzisiro ye-multi-mode superposition ndeye flat-top curve.
Yakajairika single-mode lasers: IPG YLR-2000-SM, SM ndiyo chidimbu cheSingle Mode. Iwo maverengero anoshandisa collimated focus 150-250 kuverenga saizi yenzvimbo yekutarisa, simba resimba i2000W, uye kutarisisa simba density inoshandiswa kuenzanisa.
Kuenzanisa kwe-single-mode uye akawanda-modhilaser weldingeffects
Single-mode laser: diki yepakati dhayamita, yakakwira simba density, simba rekupinda nekupinda, diki-inopisa-inopisa nzvimbo, yakafanana nebanga rakapinza, kunyanya yakakodzera kushambadzira mahwendefa matete uye kumhanyisa-welding, uye inogona kushandiswa nema galvanometers kugadzirisa diki. zvidimbu uye zvikamu zvinoratidzira zvakanyanya (zvakanyanya zvinoratidzira) nzeve, zvidimbu zvinobatanidza, nezvimwewo), sezvakaratidzwa mumufananidzo uri pamusoro, imwe-modhi ine diki kiyi hole uye shoma vhoriyamu yemukati yakakwira-kumanikidza simbi mhute, saka kazhinji haina. vane hurema hwakadai semukati pores. Pakumhanya kwakaderera, kutaridzika kwakashata pasina kuvhuvhuta mweya unodzivirira. Pakumhanya kukuru, kudzivirira kunowedzerwa. Hunhu hwekugadzirisa gasi hwakanaka, kushanda kwacho kwakakwira, mawelds akatsetseka uye akapfava, uye chiyero chegoho chakakwira. Inokodzera stack welding uye kupinza welding.
Multi-mode laser: Huru yepakati dhayamita, yakaderera zvishoma simba density pane single-mode laser, blunt banga, hombe kiyi, gobvu simbi chimiro, diki kudzika-kusvika-upamhi reshiyo, uye pasimba rimwe chete, kudzika kwekupinda kwakaderera makumi matatu muzana. kupfuura iyo ye-single-mode laser, saka yakakodzera kushandiswa Inokodzera butt weld processing uye gobvu ndiro kugadzirisa ine maburi makuru egungano.
Composite-Ring Laser Contrast
Hybrid welding: Iyo semiconductor laser beam ine wavelength ye915nm uye fiber laser beam ine wavelength ye1070nm inosanganiswa mumwechete welding musoro. Iwo maviri laser matanda akagovaniswa akagovaniswa uye iyo yakatarisana ndege dzeaviri laser matanda anogona kuchinjika, kuitira kuti chigadzirwa ive ese semiconductor.laser weldingkugona mushure mekugadzira. Mhedzisiro yacho inopenya uye ine kudzika kwefiberlaser welding.
Semiconductors anowanzo shandisa nzvimbo yakakura yemwenje inodarika mazana mana, iyo inonyanya kuita basa rekutanga kupisa zvinhu, kunyungudusa pamusoro pechinhu, uye kuwedzera chiyero chekunyudza kwefiber laser (yezvinyorwa zvekunyura kwelaser inowedzera sezvo tembiricha inowedzera)
Mhete Laser: Maviri fiber laser modules anoburitsa laser mwenje, iyo inopfuudzwa kune iyo chinhu pamusoro peiyo composite optical fiber (mhete optical fiber mukati mecylindrical optical fiber).
Maviri laser matanda ane annular nzvimbo: mhete yekunze ine basa rekuwedzera kiyi yekuvhura nekunyungudutsa zvinhu, uye yemukati mhete laser ine basa rekudzika kwekupinda, ichigonesa ultra-low spatter welding. Iyo yemukati uye yekunze mhete laser simba core diameters inogona kuenzaniswa zvakasununguka, uye iyo dhayamita yepakati inogona kuenzaniswa zvakasununguka. Iwindo rekuita rinoshanduka kupfuura iro reimwe laser beam.
Kuenzanisa kwecomposite-circular welding effects
Sezvo hybrid welding iri musanganiswa we semiconductor thermal conductivity welding uye fiber optic deep penetration welding, iyo yekunze mhete yekupinda haina kudzika, iyo metallographic chimiro chakapinza uye chakatetepa; panguva imwecheteyo, chitarisiko chiri kupisa conductivity, dziva rakanyungudutswa rine kushanduka kuduku, hukuru hukuru, uye dziva rakanyungudutswa rinonyanya kugadzikana, richiratidza kune chitarisiko chakanaka.
Sezvo mhete laser iri musanganiswa wekupinda kwakadzika welding uye yakadzika yekupinda welding, iyo yekunze mhete inogona zvakare kuburitsa kudzika kwekupinda, iyo inogona kunyatso kuwedzera kuvhurwa kwekiyi. Simba rimwechete rine kudzika kukuru kwekupinda uye kukora metallography, asi panguva imwe chete, kugadzikana kwedziva rakanyungudutswa zvishoma kudarika Kuchinja kwe optical fiber semiconductor yakakura zvishoma kudarika iyo ye composite welding, uye kushata kwacho kwakakura.
