Nyob rau hauv lub tshav pob ntawm niaj hnub industrial manufacturing, laser welding, raws li ib tug high-precision thiab high-efficiency vuam tshuab, tau txais kev saib xyuas. Rau cov neeg siv khoom muaj peev xwm ntawm cov khoom siv tes tuav laser, kev nkag siab qhov sib txawv hauv laser vuam ntawm cov khoom sib txawv steel yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo tshaj plaws thiab ua kom cov vuam zoo.
Ua ntej, cia peb paub cov khoom siv hlau ntau, xws li carbon steel, stainless hlau thiab hlau alloy.
Cov pa roj carbon steel yog ib qho ntawm cov khoom siv hlau feem ntau, thiab nws cov ntsiab lus carbon sib txawv yuav cuam tshuam rau nws txoj haujlwm. Tsawg-carbon steel muaj zoo weldability. Medium-carbon steel yuav tsum tau ceev faj ntau dua thaum vuam, thaum high-carbon steel yog nyuaj rau welding.
Stainless hlau muaj zoo corrosion kuj thiab oxidation kuj. Cov hom muaj xws li austenitic stainless hlau, ferritic stainless hlau thiab martensitic stainless hlau. Lawv muaj pes tsawg leeg thiab microstructure txiav txim siab lawv cov yam ntxwv vuam.
Alloy steel yog ib hom hlau uas tau txais cov khoom tshwj xeeb los ntawm kev ntxiv cov ntsiab lus alloying, xws li lub zog, toughness thiab hnav tsis kam.
Laser vuam muaj ntau daim ntawv thov thiab cov txiaj ntsig tseem ceeb ntawm cov khoom siv hlau sib txawv. Nws qhov siab precision tuaj yeem ua tiav qhov dav me me thiab qhov tob, yog li txo qhov cuam tshuam ntawm tshav kub thiab txhim kho vuam zoo. Lub zog ceev ceev ua kom nrawm nrawm nrawm thiab txhim kho kev ua haujlwm zoo. Ntxiv mus, lub vuam seam ntawm laser vuam yog zoo nkauj thiab muaj lub zog siab, uas tuaj yeem ua tau raws li ntau yam kev lag luam nruj.
Tom ntej no, tsom mus rau kev sib piv thiab tshuaj xyuas qhov sib txawv tseem ceeb ntawm cov khoom siv hlau sib txawv thaum lub sij hawm laser vuam txheej txheem.
Nyob rau hauv cov nqe lus ntawm kub tis, carbon steel muaj ib tug kuj siab thermal conductivity, yog li ntawd tshav kub yog kis tau sai heev thiab kub tis yog kuj sib xws. Txawm li cas los xij, stainless hlau muaj qis dua thermal conductivity thiab nws yooj yim los tsim cov kub hauv zos thaum lub sij hawm vuam, yuav tsum tau tswj kom meej dua.
Cov xwm txheej deformation kuj txawv. Feem ntau hais lus, qhov deformation ntawm carbon steel yog me me, thaum stainless hlau, vim nws cov coefficient loj ntawm thermal expansion, nws muaj ntau deformation thaum lub vuam txheej txheem.
Nyob rau hauv cov nqe lus ntawm muaj pes tsawg leeg kev hloov, thaum lub sij hawm vuam txheej txheem ntawm hlau alloy, kev faib thiab hlawv cov alloying ntsiab yuav muaj feem xyuam rau qhov zoo ntawm vuam zoo.
Rau cov hlau sib txawv, ntawm no yog qee qhov kev pom zoo laser vuam tsis thiab cov lus qhia kev.
Rau cov pa roj carbon steel, qhov vuam ceev dua thiab nruab nrab lub zog laser tuaj yeem siv los txo cov cua sov thiab tsis txhob vuam ntau dhau.
Cov hlau tsis muaj steel yuav tsum muaj qhov vuam qis dua thiab muaj zog dua. Nyob rau tib lub sijhawm, xyuam xim rau kev siv cov roj tiv thaiv kev tiv thaiv oxidation.
Cov kev sib txuas ntawm cov hlau tsis muaj hlau yuav tsum tau hloov kho raws li qhov tshwj xeeb alloy muaj pes tsawg leeg kom ntseeg tau tias cov khoom sib txawv ntawm cov hlau alloying.
Hauv kev xaus, laser vuam muaj kev cia siab dav hauv kev ua hlau. Lub xub ntiag ntawm laser vuam tuaj yeem pom hauv thaj chaw xws li kev tsim tsheb, aerospace, khoom siv hluav taws xob, thiab cov khoom siv kho mob.
Piv txwv li, nyob rau hauv automotive manufacturing, laser welding yog dav siv nyob rau hauv kev sib txuas ntawm lub tsheb lub cev qauv, kev txhim kho lub zog thiab kev ruaj ntseg ntawm lub tsheb lub cev. Nyob rau hauv aerospace teb, rau vuam ntawm high-strength alloy steel Cheebtsam, laser welding yuav xyuas kom meej siab precision thiab zoo.
Txhawm rau pab kom koj tau txais cov txiaj ntsig zoo dua hauv kev ua haujlwm tiag tiag, peb xav kom koj siv peb [hom npe] handheld laser welder. Nws nta cov tshuab laser qib siab, kev ua haujlwm ruaj khov, thiab kev ua haujlwm yooj yim, thiab tuaj yeem ua tau raws li koj qhov kev xav tau ntawm cov khoom siv hlau sib txawv. Txawm hais tias koj yog ib lub chaw tsim khoom me me lossis cov tuam txhab tsim khoom loj, peb cov khoom yuav yog tus pabcuam muaj zog rau koj los txhim kho vuam zoo thiab ua haujlwm zoo.
