Laser vuam
Hauv kev sib txuas ntawm cov khoom siv, lub zog siab laser vuam tau tsim sai heev, tshwj xeeb tshaj yog nyob rau hauv cov tsoos tsheb tsim thiab tshiab zog tsheb tsim.Nyob rau hauv lub neej yav tom ntej, qhov kev thov nyob rau hauv aerospace kev lag luam, shipbuilding kev lag luam, petrochemical kev lag luam thiab lwm yam kev lag luam yuav maj mam nce, txhawb lub technologies upgrading kev lag luam.
01 Traditional tsheb tsim kev lag luam
Tam sim no, qhov loj tshaj plaws ntawm kev lag luam laser vuam yog nyob rau hauv lub tsheb tsim kev lag luam, thiab qhov xwm txheej no yuav tsis hloov nyob rau hauv ob peb xyoos tom ntej no, thiab kev ua lag luam tseem yuav muaj kev xav tau loj heev.Laser vuam tshuab muaj xws li laser tus kheej fusion vuam, laser muab tub lim hlau fusion vuam, laser muab tub lim hlau brazing, tej thaj chaw deb scanning vuam, laser viav vias vuam, thiab lwm yam. Los ntawm cov laser vuam technologies, qhov tseeb, nruj thiab kev koom ua ke degree ntawm lub tsheb lub cev tuaj yeem txhim kho. , kom paub txog lub teeb yuag, txuag hluav taws xob, kev tiv thaiv ib puag ncig thiab kev nyab xeeb ntawm lub tsheb [1].Niaj hnub nimno tsheb ntau lawm feem ntau yog siv hom ntawm cov khoom siv tsis siv neeg.Txawm hais tias qhov txuas twg muaj kev sib tsoo, nws yuav ua rau poob hnyav, uas tseem ua rau muaj kev xav tau siab rau kev ruaj ntseg thiab kev ntseeg siab ntawm cov khoom siv hauv txhua qhov txuas.
Raws li lub hauv paus tseem ceeb ntawm cov khoom siv laser vuam, lub laser yuav tsum muaj kev ruaj ntseg ntawm cov zis hluav taws xob, ntau cov channel, tiv thaiv kev tiv thaiv siab tiv thaiv siab tiv thaiv siab tiv thaiv siab tiv thaiv kev muaj peev xwm, thiab lwm yam. Ruike Laser tau ua haujlwm ntau hauv daim teb no. thiab tau tsim cov khoom siv vuam ruaj khov thiab txhim khu kev qha.
02 Tshiab zog tsheb tsim kev lag luam
Kev lag luam tsheb fais fab tshiab tau txhim kho sai, nrog kev loj hlob tsis tu ncua hauv kev muag khoom thoob ntiaj teb thiab hauv tsev.Qhov kev thov rau nws cov khoom tseem ceeb, xws li cov roj teeb fais fab thiab cov tsav tsheb, kuj tseem loj tuaj;
Txawm hais tias nws yog kev tsim cov roj teeb fais fab lossis tsav lub cev muaj zog, muaj kev thov loj rau laser vuam.Cov ntaub ntawv tseem ceeb ntawm cov roj teeb hluav taws xob no, xws li cov roj teeb square, roj teeb cylindrical, roj teeb pob muag thiab cov roj teeb hniav, yog aluminium alloy thiab tooj liab liab.Cov plaub hau Pin lub cev muaj zog yog qhov kev txhim kho yav tom ntej ntawm tus tsav lub cev muaj zog.Cov windings thiab txuas txuas ntawm lub cev muaj zog yog tag nrho cov khoom siv tooj liab liab.Kev sib txuas ntawm ob "cov ntaub ntawv siab tiv thaiv kev cuam tshuam" yeej ib txwm muaj teeb meem.Txawm hais tias laser vuam siv, tseem muaj cov ntsiab lus mob - vuam tsim, vuam efficiency thiab vuam spatter.
Txhawm rau daws cov teeb meem no, tib neeg tau ua tiav ntau txoj kev tshawb fawb, suav nrog kev tshawb nrhiav cov txheej txheem vuam, kev tsim cov vuam pob qij txha [2], thiab lwm yam: los ntawm kev kho cov txheej txheem vuam thiab xaiv qhov sib txawv ntawm qhov sib txawv, kev tsim vuam tuaj yeem ua tau. yuav txhim kho, thiab vuam efficiency tuaj yeem txhim kho rau qee yam;Los ntawm kev tsim ntau yam tshwj xeeb vuam pob qij txha, xws li viav vias vuam pob qij txha, dual wavelength laser sib txuas vuam cov pob qij txha, thiab lwm yam., cov vuam tsim, vuam spatter thiab vuam efficiency yuav zoo heev.Tab sis nrog kev loj hlob sai ntawm kev thov, qhov vuam efficiency tseem tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua.Cov tuam txhab loj laser teeb pom kev lag luam tau qhia txog cov teeb pom kev zoo lasers los ntawm kev kho dua tshiab ntawm lasers.Lub laser no muaj ob lub coaxial laser beam outputs, thiab lub zog piv ntawm ob yuav raug kho ntawm yuav.Thaum vuam aluminium alloy thiab tooj liab liab, nws tuaj yeem ua tiav cov txiaj ntsig zoo thiab txaws dawb vuam, ua tau raws li qhov xav tau tam sim no ntawm kev lag luam tsheb tshiab, uas yuav yog lub ntsiab lus laser hauv kev lag luam hauv ob peb xyoos tom ntej no.
03 Vuam teb ntawm nruab nrab thiab tuab daim hlau
Lub vuam ntawm nruab nrab thiab tuab daim hlau yog ib qho tseem ceeb kev taw qhia ntawm laser vuam nyob rau hauv lub neej yav tom ntej.Nyob rau hauv aerospace, petrochemical, shipbuilding, nuclear fais fab nroj tsuag, rail transit thiab lwm yam lag luam, qhov kev thov rau vuam ntawm nruab nrab thiab tuab daim hlau yog loj.Ob peb xyoos dhau los, txwv los ntawm lub zog, tus nqi thiab vuam tshuab ntawm lasers, daim ntawv thov thiab kev txhawb nqa ntawm laser vuam hauv cov kev lag luam no qeeb heev.Nyob rau hauv ob xyoos tsis ntev los no, qhov kev thov rau kev txhim kho kev lag luam thiab kev tsim kho kev lag luam ntawm Tuam Tshoj txoj kev lag luam tau dhau los ua qhov ceev heev.Kev txhim kho kom zoo thiab ua haujlwm zoo yog qhov xav tau ntawm txhua qhov chaw ntawm lub neej.Laser arc hybrid welding yog suav tias yog ib qho ntawm cov thev naus laus zis zoo tshaj plaws rau nruab nrab thiab tuab phaj vuam.
