Laser vuam tshuab raws li hom tshiab ntawm cov txheej txheem vuam yog ntau thiab ntau tus neeg paub txog. Nrog kev ua haujlwm siab thiab kev sib tsoo me me, laser vuam yog dav siv hauv tsheb tsim, aerospace, kev lag luam tub rog, kev tsim khoom kho vajtse, thiab lwm yam.
Feem ntau hais lus, laser arc composite welding txais laser thiab arc dual tshav kub qhov chaw, ua ke ntawm cov khoom siv kom paub qhov melting ntawm cov khoom, thiab nrog lub zog ntawm cov cua sov qhov chaw, lub molten pas dej ua ke solidifies tsim ib tug nruam weld. Laser arc composite welding feem ntau yog siv hauv cov phaj tuab, nws qhov zoo yog pom tseeb dua. Nyob rau hauv cov nqe lus ntawm vuam efficiency, laser arc puas welding efficiency rau cov tsoos arc vuam efficiency ntawm ntau tshaj 3 lub sij hawm, nyob rau hauv lub vuam consumables (hlau, roj) noj, laser arc composite welding yog hais txog 1/5 ntawm cov tsoos vuam. Thiab laser arc composite welding nyob rau hauv vuam ntawm daim hlau tuab tsis tas yuav qhib lub bevel, txuag lub sijhawm thiab kev ua haujlwm. Yog li ntawd, cov cuab yeej siv tau siv rau hauv kev sib txuas ntawm lub nkoj nkoj hauv kev lag luam shipbuilding thiab vuam ntawm crane boom hauv kev tsim kho tshuab.
Nrog kev txhim kho txuas ntxiv ntawm MIG / MAG thev naus laus zis, laser arc sib xyaw vuam kuj tseem tsim nyog rau kev kub ceev vuam ntawm nyias daim hlau. Tsis ntev los no, Pentium laser sib koom ua ke cov cuab yeej siv hauv tsev loj heev, sib koom ua ke tsim lub laser + microMIG sib txuas vuam tshuab hauv hluav taws xob dej rhaub steel liner vuam daim ntawv thov.
Hauv kev tsim khoom ib txwm muaj, lub tshuab rhaub dej kub yog welded los ntawm cov txheej txheem plasma vuam. Plasma vuam siv lub plasma arc siab zog ceev beam raws li lub vuam kub qhov chaw ntawm fusion vuam txoj kev. Lub plasma arc muaj lub zog tsawg zog thiab qis zog ntau dua li laser, yog li nws tsis tuaj yeem paub qhov kev kub ceev vuam, uas txwv qhov kev ua tau zoo ntawm lub tshuab rhaub dej sab hauv.
Laser, raws li lub tshav kub qhov chaw nrog lub zog siab tshaj plaws, yog dav siv nyob rau hauv vuam ntawm lithium roj teeb thiab ntawv, automotive qhov chaw, aerospace qhov chaw, tub rog thiab lwm yam khoom. Txawm li cas los xij, laser vuam kuj muaj qee qhov kev txwv tsis pub siv, piv txwv li, hauv cov txheej txheem laser nws tus kheej melting welding, cov pab pawg welding mus rau qhov sib txawv ntawm qhov yuav tsum tau muaj siab heev, qhov sib txawv yog siab, qhov sib txawv me me. Yog li ntawd, txhawm rau ua kom tiav cov kev xav tau ceev ceev, thiab cov kev xav tau ntawm vuam seam tag nrho, qhov chaw ntawm qhov loj seem ntawm qhov siab ntawm qhov chaw, yuav tsum tau siv cov txheej txheem laser arc composite vuam.
Dej rhaub carbon steel liner thickness feem ntau tsawg dua 2 hli, teej tug mus rau nyias phaj thickness ntau. Kev lig kev cai MIG / MAG thiab laser composite vuam yuav ua rau cov cua kub loj ntawm cov vuam, qhov vuam HAZ thaj tsam loj dua, qhov tawv tawv nce, tsis zoo rau kev txhim kho lub zog qaug zog ntawm sab hauv liner. Yog li ntawd, Pentium Laser thov kom siv laser + microMIG (CMT) vuam txheej txheem. Laser + microMIG (CMT) kev sib xyaw tsis tsuas yog tuaj yeem paub txog tag nrho kev nkag mus ntawm laser high-speed vuam, microMIG (CMT) thiab tuaj yeem xyuas kom meej tias qhov vuam nto tsim thiab qhov seem seem. Pentium laser vuam xeem, laser + microMIG (CMT) qhov siab tshaj vuam ceev tuaj yeem ncav cuag 3.6m / min, yog cov tshuaj plasma vuam efficiency ntau tshaj 3 zaug. Lub caij no, kev siv cov khoom siv vuam vuam yog 1/3 ntawm cov txheej txheem vuam qub.
Tom qab laser + microMIG (CMT) welding, qhov siab ntawm qhov ncaj seam ntawm lub puab liner yog tswj nyob rau hauv 1 hli, thiab cov yaj dav yog hais txog 3 hli, thiab qhov siab ntawm lub hauv qab seam yog tswj nyob rau hauv 0. 5mm, thiab qhov dav dav yog li 1.5mm. Lub weld seam ntawm cov qauv tom qab vuam yog tsim uniformly thiab tag nrho ntawm ib zaug.
Piv nrog rau cov plasma welding ib txwm muaj, laser + microMIG (CMT) tuaj yeem paub cov vuam zoo nyob rau hauv qhov chaw ntawm kev lav qhov zoo ntawm cov vuam seam, thiab cov welded puab liner tau qaug zog rau ntau tshaj 200, 000 zaug ntawm lub siab tshaj (160, 000 lub sij hawm ntawm kev xeem qaug zog yog tsim nyog). Nws ua tau raws li qhov yuav tsum tau ua ntawm cov hlau sab hauv liner rau hluav taws xob dej rhaub.
