01 yog awelded sib koom
Ib qho kev sib txuas welded yog hais txog kev sib koom ua ke uas ob lossis ntau lub workpieces txuas nrog vuam. Lub welded sib koom ua ke ntawm fusion vuam yog tsim los ntawm cov cua sov hauv zos los ntawm qhov chaw kub-kub kub. Lub welded sib koom ua ke muaj fusion zone (weld zone), fusion kab, tshav kub cuam tshuam cheeb tsam, thiab lub hauv paus hlau cheeb tsam, raws li qhia hauv daim duab.
02 Lub pob tw yog dab tsi
Ib qho kev siv vuam siv feem ntau yog kev sib koom ua ke uas ob qhov sib txuas sib txuas tau welded nyob rau hauv tib lub dav hlau los yog arc ntawm qhov nruab nrab ntawm qhov sib koom ua ke. Cov yam ntxwv yog cov cua kub sib xws, lub zog tsis sib xws, thiab yooj yim los xyuas kom zoo vuam zoo.
03 yog avuam zawj
Txhawm rau kom ntseeg tau tias kev nkag mus thiab qhov zoo ntawm cov pob qij txha welded, thiab txo cov vuam deformation, cov pob qij txha ntawm cov welded feem ntau ua ntej ua tiav rau hauv ntau yam duab ua ntej vuam. Qhov sib txawv vuam grooves yog tsim rau txawv vuam txoj kev thiab weldment thicknesses. Cov ntaub ntawv groove feem ntau suav nrog: I-puab, V-puab, U-puab, unilateral V-puab, thiab lwm yam, raws li qhia hauv daim duab.

04 Qhov cuam tshuam ntawm Butt Joint Groove Form onLaser Arc Composite Vuam
Raws li lub thickness ntawm lub welded workpiece nce, ua tiav ib leeg-ib sab welding thiab ob-sided forming ntawm nruab nrab thiab tuab daim hlau (laser zog <10 kW) feem ntau ua complex. Feem ntau, cov tswv yim vuam sib txawv yuav tsum tau txais kev pom zoo, xws li tsim cov ntaub ntawv groove tsim nyog lossis khaws qee qhov sib txawv ntawm qhov sib txawv, thiaj li ua tiav cov vuam ntawm nruab nrab thiab tuab daim hlau. Txawm li cas los xij, nyob rau hauv qhov tseeb welding, khaws cia qhov sib txawv ntawm qhov sib txawv yuav ua rau qhov nyuaj ntawm vuam fixtures. Yog li ntawd, qhov tsim ntawm qhov zawj yog qhov tseem ceeb thaum lub sij hawm vuam txheej txheem. Yog tias tus qauv tsim tsis tsim nyog, kev ruaj ntseg thiab kev ua haujlwm ntawm vuam yuav raug cuam tshuam, thiab nws kuj ua rau muaj kev pheej hmoo ntawm vuam tsis xws luag.
(1) Daim ntawv zawj ncaj qha cuam tshuam rau qhov zoo ntawm cov vuam seam. Qhov tsim nyog zawj tuaj yeem ua kom ntseeg tau tias cov vuam hlau hlau tau ntim rau hauv cov vuam seam, txo qhov tshwm sim ntawm vuam tsis xws luag.
(2) Cov duab geometric ntawm qhov zawj cuam tshuam rau txoj kev tshav kub hloov mus, uas tuaj yeem coj cov cua sov zoo dua, ua kom muaj cua sov ntau dua thiab ua kom txias, thiab pab kom tsis txhob thermal deformation thiab kev ntxhov siab.
(3) Daim ntawv zawj yuav cuam tshuam rau qhov sib txawv ntawm qhov sib txawv ntawm qhov vuam seam, thiab nws yuav ua rau qhov sib txawv ntawm qhov sib txawv ntawm qhov vuam seam ntau dua raws li cov kev cai tshwj xeeb, xws li vuam qhov tob thiab qhov dav.
(4) Daim ntawv groove tsim nyog tuaj yeem txhim kho kev ruaj ntseg ntawm vuam thiab txo qhov tshwm sim tsis ruaj khov thaum lub sij hawm vuam, xws li txaws thiab txiav tsis xws luag.
Raws li pom nyob rau hauv daim duab 3, cov kws tshawb fawb tau pom tias siv laser arc composite welding (laser fais fab 4kW) tuaj yeem sau cov zawj hauv ob txheej thiab ob txoj kev hla, kev txhim kho vuam efficiency; Ib qho tsis xws luag dawb vuam ntawm 20 hli tuab MnDR tau ua tiav siv peb txheej laser arc puas vuam (laser zog ntawm 6kW); Laser arc composite welding tau siv los vuam 30 hli tuab qis-carbon steel nyob rau hauv ntau txheej thiab hla, thiab tus ntoo khaub lig-sectional morphology ntawm cov welded sib koom yog ruaj khov thiab zoo. Tsis tas li ntawd, cov kws tshawb fawb tau pom tias qhov dav ntawm cov grooves thiab lub kaum sab xis ntawm Y-zoo li tus grooves muaj qhov cuam tshuam loj heev rau cov nyhuv spatial. Thaum qhov dav ntawm lub voj voos zawj yog≤4mm thiab lub kaum sab xis ntawm Y-puab zawj yog≤60 °, cross-section morphology ntawm weld seam qhia cov kab nrib pleb thiab sab phab ntsa, raws li qhia hauv daim duab.

05 Cov ntsiab lus
Kev xaiv ntawm daim ntawv zawj yuav tsum ua tib zoo 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 laser arc sib xyaw. Tsim kom zoo zawj tuaj yeem txhim kho vuam efficiency thiab txo qhov kev pheej hmoo ntawm vuam tsis xws luag. Yog li ntawd, kev xaiv thiab tsim ntawm daim ntawv zawj yog qhov tseem ceeb ua ntej laser arc puas vuam ntawm nruab nrab thiab tuab daim hlau.
