1. Cov qauv ua haujlwm tseem ceeb hauv Laser Vuam
Ob peb cov qauv tseem ceeb cuam tshuam Weld Zoo, xwm yeem, thiab efficiency:
a. LASER Fais
Txiav txim siab lub zog xa mus rau cov khoom siv.
Lub zog siab dua yog siv rau tob lossis tuab welds.
Ntau dhau lub zog tuaj yeem ua rau muaj qhov sib npaug lossis hlawv - los ntawm.
b. Vuam ceev
Kev nrawm nrawm txo cov lus tawm ua kom sov, txo qis kev cuam tshuam.
Kev nrawm heev yuav ua rau tsis tiav Fusion lossis Porosity.
Kev qeeb zuj zus tuaj yeem ua kom sov thiab kev pheej hmoo ntawm deformation.
c. Tsom Xam Haujlwm
Txoj hauj lwm ntawm lub laser focal point cuam tshuam rau kev tob tob thiab cov leeg tawv.
Ib qho teeb pom kev zoo tsom ua kom muaj zog ua kom muaj zog thiab ruaj khov txuas.
d. Mem nuj nqis chaw (rau pulsed laser vuam)
Mem tes zaus, ntev, thiab lub zog cuam tshuam rau kev ua kom sov sov.
Qhov zoo tagnrho rau cov khoom siv nyias lossis cov chaw welding.
2. Tiv thaiv cov roj: hom thiab lub luag haujlwm
Kev thaiv cov roj tiv thaiv cov pas dej molten los ntawm oxidation thiab paug. Nws kuj cuam tshuam Arc Stability, tus nqi txias, thiab pom pom kev.
Hom roj ntau li:
Tus sib cav
Feem ntau siv roj.
Inert, muab kev tiv thaiv zoo.
Haum rau feem ntau cov hlau.
Nitrogen
Tuaj yeem txhim kho cov khoom siv tau rau qee cov hlau tsis muaj roj.
Pheej yig dua li argon tab sis tsis haum rau txhua cov ntaub ntawv.
Helium
Muaj cov thermal siab conductivity.
Siv rau cov ntaub ntawv tuab tuab lossis siab dua - ceev vuam.
Kim kim dua, feem ntau tov nrog argon.
3. Roj Flow tus nqi thiab xa khoom
Kho roj ntws yog qhov tseem ceeb heev. Ob yamtsawg dhauthiabsiab dhautuaj yeem ua rau weld tsis xws luag.
Flow tsawg heev:
Kev tiv thaiv tsis zoo.
Nce kev pheej hmoo ntawm porosity, oxidation, thiab discoloration.
Txaus siab heev:
Tuaj yeem ua rau muaj kev kub ntxhov, nqus tau huab cua mus rau hauv thaj chaw weld.
Tej zaum yuav txias lub weld sai sai, ua rau tawg lossis nkig microstructure.
Kiag tus nqi:
10-25 l / min rau feem ntau laser vuam cov ntawv thov.
Nyob ntawm cov khoom, sib koom tes hom, thiab nozzle tsim.
4. Raug cuam tshuam rau kev coj ua
Khoom Hom: Aluminium thiab tooj kho kom tau ntau dua laser fais fab thiab ntau dua inert tiv thaiv roj vim lawv qhov kev xav zoo siab thiab kev ua haujlwm siab.
Nto huv: Cov paug ntawm cov ua haujlwm tuaj yeem ua rau muaj kev tiv thaiv roj av, ua cov roj npuas lossis slag.
Kev Sib Tw Rau Gumetry: Cov duab nyuaj lossis cov chaw kaw kom muaj zog yuav cuam tshuam cov roj teeb thiab yuav tsum tau kho cov roj ntsha thiab kho kom haum lossis kho kom haum.
Tag
Ua tiav qhov siab - Zoo Laser Word nyob ntawm tsis xaiv cov khoom lag luam laser no tsis yog siv kho cov qauv thiab kev thaiv cov roj teeb. Kev tswj hwm lub zog laser, nrawm, ua kom pom tseeb, oxidation pab tiv thaiv tsis xws luag, thiab kev tawg ua kom zoo nkauj thiab txhim khu kev qha nyob rau ntau cov ntawv thov.
