Laser-Arc Hybrid Vuam

Raws li kev siv thev naus laus zis tshiab, laser-arc hybrid welding siv laser thiab arc ua ob qhov chaw tshav kub, uas ua rau tib lub pas dej molten tib lub sijhawm los tsim ib lub laser-guided thiab ruaj khov arc. Lub arc txhim kho lub laser nqus tus nqi ntawm cov hlau thiab txhim khu kev hloov thiab txuas ntawm cov molten droplets. Ib txoj kev muaj peev xwm welding uas muab kev ua si tag nrho rau qhov zoo ntawm laser vuam thiab arc vuam thiab ua rau lawv qhov tsis zoo. Tshwj xeeb tshaj yog nyob rau hauv vuam ntawm nruab nrab thiab loj thickness cov ntaub ntawv, hybrid vuam tshuab muaj ntau yam zoo. Vim tias cov txheej txheem vuam ib txwm muaj qhov tsis zoo xws li kev sib koom ua ke tsis muaj zog, kev ua haujlwm tsis zoo, deformation loj, thiab siv cov khoom siv vuam loj; thiab ib leeg laser welding kuj muaj qee qhov tsis txaus, xws li kev sib koom ua ke ntawm cov txheej txheem siab thiab vuam muaj peev xwm txwv los ntawm lub zog laser. Loj, tsis zoo bridging peev xwm, loj undercutting welds, thiab lwm yam.

Raws li txoj kev vuam tshiab, laser-arc hybrid vuam muaj peb yam tseem ceeb hauv qab no:
1) Txhim kho kev siv hluav taws xob, ua kom cov vuam nkag qhov tob thiab vuam ceev;
2) Txo cov haujlwm ua haujlwm sib dhos;
3) Txhim kho weld zoo thiab txhim kho weld tsim.

Muaj ntau hom laser-arc hybrid vuam, xws li Laser-MAG/MIG hybrid vuam, Laser-TIG hybrid vuam, laser-plasma arc hybrid vuam, thiab lwm yam. thiab semiconductor lasers. Piv txwv li, Raycus nruam fiber ntau laser 4000W, 6000W thiab fiber ntau output semiconductor laser 4000W.

Laser-MAG hybrid vuam muaj ob qhov chaw vuam kub, uas yog laser thiab MAG arc. Thaum siv los ua ib qho chaw sov so rau vuam, lub pas dej molten zoo tuaj yeem tsim tau, tab sis cov yam ntxwv ntawm lub pas dej molten sib txawv: cov yam ntxwv ntawm lub laser vuam molten pas dej ua ke yog "qhov tob thiab nqaim" ", qhov chaw qhib me me thiab qhov tob yog qhov loj, uas tsis yog qhov tsim nyog rau kev tsim cov welding; MAG arc vuam molten pas dej ua ke yog tus cwj pwm los ntawm kev ua "ntiav thiab dav", qhov chaw qhib loj thiab qhov tob me me, uas yog qhov tsim nyog rau kev tsim ntawm lub weld thiab muaj zog bridging muaj peev xwm.

During the Laser-MAG composite welding process, two heat sources act on the base material at the same time. There is mutual influence between the two heat sources, and there is also mutual influence between the two molten pools, which will eventually form a new composite molten pool. This composite molten pool has both the "large depth" of the laser molten pool and the "large area" of the arc molten pool. This composite molten pool has a large depth, good weld formation, and strong bridging ability. At the same time, because of the MAG arc welding There is welding wire filling, and the type of welding wire can be selected, so according to the performance defects of the base material itself, the appropriate welding wire can be selected and added to the welding process, thereby improving the crack resistance, fatigue resistance, and corrosion resistance of the weld at the micro level. , wear resistance and other aspects to carry out purposeful improvements. In addition, during the entire welding process, there are two heat sources acting on the base material. The mutual influence between them can increase the penetration depth and achieve the effect of "1+1>2 "Yog li ntawd, ib qho melting point ntawm laser-arc hybrid welding yog lub peev xwm nkag tau zoo heev. Thaum kawg, laser-arc hybrid welding tuaj yeem ua tiav ntau qhov kev sib tw vuam thiab vuam ntawm cov ntaub ntawv loj tuab, thiab fusion peev xwm ntawm lub sab sauv thiab qis weld hlaws thiab sab phab ntsa muaj zog heev vim lub arc.
