01 Dab tsi yog ib qhokev sib koom ua ke
Ib qho sib txuas uas vuam yog hais txog ib qho sib txuas uas ob lossis ntau qhov workpieces txuas nrog los ntawm kev vuam. Qhov sib txuas vuam ntawm kev vuam fusion yog tsim los ntawm kev cua sov hauv zos los ntawm qhov chaw kub siab. Qhov sib txuas vuam muaj ib cheeb tsam fusion (cheeb tsam vuam), kab fusion, thaj chaw cuam tshuam cua sov, thiab thaj chaw hlau, raws li pom hauv daim duab.
02 Dab tsi yog lub pob tw sib koom ua ke
Ib qho qauv vuam uas siv ntau yog qhov sib koom ua ke uas ob qhov sib txuas ua ke raug vuam rau hauv tib lub dav hlau lossis arc ntawm nruab nrab ntawm qhov sib koom ua ke. Qhov yam ntxwv yog cua sov sib npaug, lub zog sib npaug, thiab yooj yim los xyuas kom meej qhov zoo ntawm kev vuam.
03 Dab tsi yog ib qhovuam qhov
Yuav kom ntseeg tau tias cov pob qij txha vuam tau nkag mus thiab zoo, thiab txo qhov kev hloov pauv ntawm kev vuam, cov pob qij txha ntawm cov khoom vuam feem ntau raug ua ntej ua ntau yam duab ua ntej vuam. Cov qhov vuam sib txawv yog qhov tsim nyog rau ntau txoj kev vuam thiab qhov tuab ntawm kev vuam. Cov duab grooves feem ntau muaj xws li: I-puab, V-puab, U-puab, ib sab V-puab, thiab lwm yam, raws li qhia hauv daim duab.

04 Qhov Cuam Tshuam ntawm Butt Joint Groove Form rauLaser Arc Composite Vuam
Thaum qhov tuab ntawm cov khoom siv vuam nce ntxiv, kev ua tiav kev vuam ib sab thiab kev tsim ob sab ntawm cov phaj nruab nrab thiab tuab (lub zog laser <10 kW) feem ntau dhau los ua qhov nyuaj dua. Feem ntau, cov tswv yim vuam sib txawv yuav tsum tau siv, xws li tsim cov duab groove tsim nyog lossis khaws qee qhov docking gaps, txhawm rau ua tiav kev vuam ntawm cov phaj nruab nrab thiab tuab. Txawm li cas los xij, hauv kev vuam ntau lawm tiag tiag, kev khaws cov docking gaps yuav ua rau muaj kev nyuaj ntawm kev vuam khoom. Yog li ntawd, kev tsim qauv ntawm qhov groove dhau los ua qhov tseem ceeb thaum lub sijhawm vuam. Yog tias qhov tsim qauv groove tsis tsim nyog, kev ruaj khov thiab kev ua haujlwm ntawm kev vuam yuav raug cuam tshuam tsis zoo, thiab nws kuj ua rau muaj kev pheej hmoo ntawm kev vuam tsis zoo.
(1) Cov duab ntawm qhov zawj cuam tshuam ncaj qha rau qhov zoo ntawm cov xov hlau vuam. Kev tsim cov zawj tsim nyog tuaj yeem ua kom cov hlau vuam tau puv tag nrho rau hauv cov xov hlau vuam, txo qhov tshwm sim ntawm cov qhov tsis zoo ntawm kev vuam.
(2) Cov duab geometric ntawm qhov zawj cuam tshuam rau txoj kev hloov pauv cua sov, uas tuaj yeem coj cua sov zoo dua, ua kom muaj cua sov thiab txias sib xws, thiab pab kom tsis txhob muaj kev hloov pauv thermal thiab kev ntxhov siab seem.
(3) Daim ntawv groove yuav cuam tshuam rau qhov cross-sectional morphology ntawm weld seam, thiab nws yuav ua rau qhov cross-sectional morphology ntawm weld seam ua raws li cov kev cai tshwj xeeb, xws li qhov tob thiab dav ntawm weld penetration.
(4) Ib daim duab groove tsim nyog tuaj yeem txhim kho qhov ruaj khov ntawm kev vuam thiab txo cov xwm txheej tsis ruaj khov thaum lub sijhawm vuam, xws li kev sib txhuam thiab kev txiav tsis zoo.
Raws li pom hauv Daim Duab 3, cov kws tshawb fawb tau pom tias kev siv laser arc composite welding (laser fais fab 4kW) tuaj yeem sau qhov zawj hauv ob txheej thiab ob qhov dhau, ua kom zoo dua qhov vuam zoo; Kev vuam tsis muaj qhov tsis xws luag ntawm 20mm tuab MnDR tau ua tiav siv peb txheej laser arc composite welding (laser fais fab ntawm 6kW); Laser arc composite welding tau siv los vuam 30mm tuab qis-carbon hlau hauv ntau txheej thiab dhau, thiab cov duab sib tshuam ntawm qhov sib koom ua ke tau ruaj khov thiab zoo. Tsis tas li ntawd, cov kws tshawb fawb tau pom tias qhov dav ntawm cov grooves rectangular thiab lub kaum sab xis ntawm Y-puab grooves muaj qhov cuam tshuam loj rau qhov cuam tshuam ntawm qhov chaw. Thaum qhov dav ntawm cov groove rectangular yog≤4 hli thiab lub kaum sab xis ntawm Y-puab qhov yog≤60 °, qhov cross-section morphology ntawm lub weld seam qhia cov kab nrib pleb hauv nruab nrab thiab cov phab ntsa sab notches, raws li pom hauv daim duab.

05 Cov Lus Qhia Luv Luv
Kev xaiv cov duab groove yuav tsum xav txog qhov yuav tsum tau ua ntawm txoj haujlwm vuam, cov yam ntxwv ntawm cov khoom siv, thiab cov yam ntxwv ntawm cov txheej txheem vuam laser arc composite. Kev tsim cov duab groove kom zoo tuaj yeem txhim kho kev ua haujlwm vuam thiab txo qhov kev pheej hmoo ntawm kev puas tsuaj ntawm kev vuam. Yog li ntawd, kev xaiv thiab tsim cov duab groove yog qhov tseem ceeb ua ntej laser arc composite vuam ntawm cov phaj nruab nrab thiab tuab.
