1. Galvanized ntawv
Galvanized ntawv yuav tsum yog cov khoom siv vuam ntau tshaj plaws. Lub gasification kub ntawm zinc yog tsawg tshaj li qhov melting point ntawm hlau, yog li nws yog yooj yim dua rau cov duab thiab welding thaum vuam. Tau kawg, vim qhov no, cov ntawv galvanized kuj tseem muaj qhov tsis xws luag thaum vuam. Raws li zinc tsis tu ncua evaporates, cov nkev generated yuav nkag mus rau hauv lub weld tsim pores los yog undercuts. Haum rau laser vuam.
2. Stainless hlau
Peb feem ntau hnov cov ntaub ntawv stainless hlau. Cov khoom siv vuam feem ntau suav nrog austenitic stainless hlau, ferritic stainless hlau, thiab martensitic stainless hlau.
1. Austenitic stainless hlau
Austenitic stainless hlau tau zoo dua vuam kev ua tau zoo, me me thermal conductivity tab sis siab nqus tus nqi. Thaum nws yog siv nyob rau hauv laser vuam, lub vuam ceev yog ceev thiab lub tshav kub input me me. Austenitic stainless hlau yog siv ntau dua hauv Cr Ni series stainless hlau vuam kev ua haujlwm, thiab laser vuam siv ntau dua los vuam austenitic stainless hlau, zoo zam nws qhov deformation thiab seem.
2. Ferritic stainless hlau
Qhov zoo ntawm ferritic stainless hlau yog nws super toughness thiab zoo ductility. Hauv cov txheej txheem vuam, qhov cuam tshuam tsawg heev. Piv txwv li, austenite thiab martensite yuav tawg thaum lub sij hawm laser vuam, tab sis ferrite zoo txo qhov muaj peev xwm.
3. Martensitic stainless hlau
Martensitic stainless hlau tej zaum yuav coj txawv txawv rau txhua leej txhua tus, vim hais tias nws cov kev ua tau zoo nyob deb inferior rau cov austenitic stainless hlau thiab ferritic stainless hlau. Txias tawg feem ntau tshwm sim thaum martensitic stainless hlau siv rau vuam, thiab cov nyhuv vuam tsis zoo. Qee qhov kev siv vuam nrog cov kev xav tau qis dua thiab cov nqi siv qee zaus, thiab qhov siv ntau zaus tsis siab.
3. Alloy hlau
Alloy steel kuj ua rau cov kab nrib pleb txias thaum vuam, tab sis nws qhov zoo dua yog tias nws tuaj yeem ncaj qha welded ntawm chav tsev kub, thiab nws cov hardness siab. Rau qee qhov kev siv nrog cov kev xav tau nruj nruj, alloy steel vuam yog qhov kev xaiv zoo. Rau alloy steel welding, laser vuam feem ntau yog siv. Qee lub tsheb sib kis, txawm tias lub cav qhov chaw ntawm lub dav hlau, yuav raug siv los vuam hlau hlau.
