Ua ntej xyoo 1970, lub tshuab siv hluav taws xob muaj zog txuas ntxiv (CW) lasers tseem tsis tau tsim, yog li kev tshawb fawb tsom mus rau kev siv lub tshuab pulsed laser welding (PW). Cov kev tshawb fawb tshawb fawb thaum ntxov feem ntau siv cov ruby pulsed lasers. Lub zog tso tawm qhov siab tshaj plaws Pm ntawm 1ms mem tes yog kwv yees li 5KW, lub zog siv hluav taws xob yog 1 ~ 5J, thiab cov mem tes zaus tsawg dua lossis sib npaug rau 1 Hz. Txawm hais tias nws muaj peev xwm nyob nrog lub zog mem tes siab dua nyob rau lub sijhawm ntawd, lub zog tso tawm nruab nrab P ntawm cov lasers no tau qis heev, uas tau txiav txim siab feem ntau los ntawm kev ua haujlwm qis ntawm lub laser thiab cov khoom zoo siab ntawm cov khoom siv luminescent. Vim tias nws lub zog nruab nrab siab, lub tshuab laser tau dhau los ua cov cuab yeej zoo dua rau qhov chaw vuam thiab cov hlua txuas tom qab nws tshwm sim. Cov txheej txheem vuam yog ua los ntawm kev siv vuam sib txuas kom txog thaum lub zog txuas ntxiv ua haujlwm laser ntau dua 1KW yug. Qhov tiag laser seam vuam tuaj yeem paub.
Qhov xwm txheej tam sim no thiab kev cia siab ntawm Vuam Automation Technology
Nrog rau kev loj hlob zuj zus ntawm cov thev naus laus zis, cov tshuab siv vuam siv hluav taws xob thiab thev naus laus zis tswj kev siv xov tooj sib txuas thev naus laus zis hauv cov chaw ua haujlwm sawv cev tau nkag mus tsis tu ncua. Peb Txoj Haujlwm Gorges, Sab Hnub Poob-Sab Hnub Poob Project, kev tsim vaj tsev hauv av, kev tsim nkoj thiab lwm qhov haujlwm loj hauv tebchaws tau txhawb nqa kev txhim kho thiab kev vam meej ntawm kev siv vuam zoo, tshwj xeeb tshaj yog vuam siv tshuab. Kev tsim cov tsheb thiab cov khoom siv yuav tsum tau hloov pauv vuam siv lub tshuab. Kuv lub tebchaws' kev lag luam vuam tau maj mam txav mus rau&"kev ua haujlwm siab, kev siv tshuab kom zoo, thiab kev txawj ntse &". Kev siv vuam siv tshuab hauv kuv lub tebchaws tseem tsawg dua 30%, uas nyob deb ntawm 80% hauv cov tebchaws tsim khoom lag luam. Txij li thaum xyoo pua 20th, cov tebchaws tau maj mam txhawb txoj kev siv vuam yooj yim ntawm kev siv lub tshuab tsis siv neeg-roj tiv thaiv vuam hauv ntau yam kev lag luam los hloov cov txheej txheem ib txwm siv arc vuam, uas tau ua tiav cov txiaj ntsig pib. Nws tuaj yeem kwv yees tau tias yav tom ntej, kev siv tshuab siv tshuab siv tshuab hauv tsev yuav txhim kho ntawm qhov tsis tau pom dua.
Qhov xwm txheej tam sim no ntawm kev siv tshuab ua haujlwm zoo thiab siv lub tshuab ua haujlwm tsis zoo
Xyoo 1990, kuv lub tebchaws' kev lag luam vuam tau ua tiav ntawm kev siv tshuab thiab kev siv tshuab vuam txheej txheem raws li lub hom phiaj phiaj xwm. Nws tau ua tiav hauv kev txhim kho kev tshawb fawb thiab thev naus laus zis hauv ntau yam lag luam. Nws tab tom txhim kho vuam tsim khoom siv tshuab, tshawb nrhiav thiab tsim cov vuam tsim cov kab thiab hloov pauv cov cuab yeej tsim khoom, thiab tsim cov ntawv thov Khoos phis tawj pab tsim thiab tsim khoom; flux-cored welding hlau nce los ntawm 2% mus rau 20%; submerged arc vuam cov khoom siv tseem yuav txuas ntxiv mus rau qib 10%. Ntawm lawv, qhov kev loj hlob ntawm flux-cored vuam hlau tau nce ntau ntxiv, thiab yuav tshaj qhov ntawm cov hlau-cored vuam hlau nyob rau 20 xyoo tom ntej, thiab nws thiaj li dhau los ua cov khoom lag luam ntawm lub chaw vuam.
