Qhov loj ntawm lub laser core txoj kab uas hla tuaj yeem cuam tshuam qhov kev xa tawm tsis zoo thiab lub zog ntom ntom ntawm lub teeb. Kev xaiv tsim nyog ntawm cov tub ntxhais txoj kab uas hla yog qhov tseem ceeb heev. Cov tub ntxhais txoj kab uas hla ntau dhau tuaj yeem ua rau muaj kev cuam tshuam ntawm hom thiab tawg hauv laser kis, cuam tshuam rau beam zoo thiab tsom qhov tseeb. Ib txoj kab uas hla me me tuaj yeem ua rau txo qis hauv qhov sib luag ntawm ib hom fiber ntau optical zog ntom ntom, uas tsis tsim nyog rau kev sib kis ntawm siab - lub zog lasers.
1, Qhov zoo thiab kev siv ntawm me me txoj kab uas hla Lasers (<100um)
Cov ntaub ntawv zoo heev: aluminium, tooj liab, stainless hlau, nickel, molybdenum, thiab lwm yam;
High reflective khoom (txhuas, tooj liab) workpieces
① High reflectivity materials require the selection of small core diameter lasers, which use high-power density laser beams to quickly heat the material to a liquefied or vaporized state, improve the material's laser absorption rate, and achieve efficient and fast processing. Xaiv cov lasers nrog cov tub ntxhais loj diameters yooj yim tuaj yeem ua rau muaj kev cuam tshuam siab, ua rau tsis muaj tseeb, thiab txawm hlawv tawm lub laser;
Cov khoom tawg yooj yim: npib tsib xee, npib tsib xee plated tooj liab, txhuas, stainless hlau, titanium alloy, thiab lwm yam.
② Cov khoom siv no feem ntau yuav tsum muaj kev tswj xyuas nruj ntawm thaj chaw tshav kub thiab yuav tsum muaj lub pas dej me me. Xaiv ib tug me me txoj kab uas hla laser yog tsim nyog;
Kev kub ceev laser ua:
③ Kev sib sib zog nqus nqus vuam yuav tsum tau ua haujlwm siab - laser ceev, thiab nws yog ib qho tsim nyog yuav tsum xaiv lub siab - lub zog ceev laser kom paub meej tias cov kab hluav taws xob txaus los yaj cov khoom ntawm kev kub ceev. Tshwj xeeb tshaj yog rau pawg vuam, nkag mus vuam, thiab lwm yam kev xav tau siab rau kev nkag mus tob, nws yog qhov tsim nyog los xaiv lub me me txoj kab uas hla laser.
Daim ntawv thov ntawm Loj Core Diameter Laser
2, Advantages and Applications of Large Core Diameter Lasers (>100 hli)
Cov tub ntxhais txoj kab uas hla loj thiab lub teeb loj loj, nrog rau thaj tsam loj tshav kub thiab thaj chaw siv dav, thiab tsuas yog ua tiav micro melting ntawm cov khoom nto, yog qhov tsim nyog rau kev siv hauv laser cladding, laser remelting, laser annealing, laser hardening, thiab lwm yam. Hauv cov teb no, cov teeb pom kev loj loj txhais tau tias muaj kev ua haujlwm ntau dua thiab qis dua (thermal conductivity vuam yuav luag tsis muaj qhov tsis xws luag).
Nyob rau hauv vuam, loj lub teeb me ntsis yog tsuas yog siv rau kev sib txuas vuam, uas yog siv rau laser cladding nrog me me diameters. Lub teeb pom kev loj ua rau saum npoo ntawm cov khoom kom yaj me ntsis, hloov los ntawm cov khoom mus rau cov kua, ua kom cov khoom nqus tau zoo heev ntawm laser. Tom qab ntawd, ib qho keyhole yog drilled nrog ib tug me me txoj kab uas hla los tsim ib tug tob tob. Thaum lub sij hawm tus txheej txheem no, vim preheating thiab post- kev kho mob ntawm lub teeb pom kev loj, nrog rau qhov loj kub gradient muab rau lub pas dej ua ke molten, Qhov no ua rau cov ntaub ntawv tsis tshua muaj kev puas tsuaj tshwm sim los ntawm cua sov thiab cua txias sai, thiab kuj ua rau cov weld zoo li smoother, thaum ua tiav cov txaws qis dua piv rau ib qho kev daws teeb meem laser.
