Nyob rau hauv niaj hnub manufacturing, daim ntawv thov ntawm2000W fiber ntau laser vuam tshuabrau welding aluminium hlau yog nce zuj zus. Txawm li cas los xij, txhawm rau ua kom cov vuam zoo thiab kev nyab xeeb, cov teeb meem tseem ceeb hauv qab no yuav tsum raug sau tseg.
1. Kev kho deg ua ntej vuam
Cov oxide zaj duab xis nyob rau saum npoo ntawm txhuas hlau tuaj yeem cuam tshuam rau kev vuam zoo. Kev kho saum npoo zoo yuav tsum tau ua kom tshem tawm cov oxide zaj duab xis, roj stains thiab lwm yam impurities. Thaum ib qho kev lag luam hauv tsheb welded aluminium thav duab, vim qhov tsis saib xyuas ntawm kev kho deg, ntau qhov pores thiab tawg tau tshwm sim hauv qhov vuam, thiab qhov tsim nyog tus nqi poob qis heev. Tom qab txhim kho cov txheej txheem kho mob, qhov kev tsim nyog tau nce mus rau ntau dua 95%.
2. Xaiv qhov tsim nyog Vuam Parameters
Vuam tsis xws li laser fais fab, vuam ceev thiab tsom txoj hauj lwm tseem ceeb heev. Rau cov ntawv txhuas nrog lub thickness ntawm 2 - 3 hli, lub zog ntawm 1500 - 1800W yog qhov tsim nyog dua; rau cov neeg uas muaj lub thickness ntawm 3 - 5 hli, 1800 - 2000W yog haum. Qhov vuam ceev yuav tsum phim lub zog. Piv txwv li, thaum lub zog yog 1800W, qhov ceev ntawm 5 - 7mm / s yog qhov zoo tagnrho. Txoj hauj lwm ua kom pom tseeb kuj cuam tshuam rau cov nyhuv vuam. Kev tsom rau cov phaj nyias nyias yog nyob ntawm qhov chaw, thaum rau cov phaj tuab, nws yuav tsum tau ua kom tob rau hauv.
3. Kev tswj cov cua kub nkag
Aluminium hlau muaj cov thermal conductivity siab thiab ua rau kub poob, uas cuam tshuam rau cov vuam nkag thiab lub zog. Yuav tsum muaj kev tswj xyuas cov cua sov kom zoo. Piv txwv li, thaum lub tuam txhab aerospace welded aluminium qhov chaw, kev tswj tsis zoo ntawm cov khoom siv hluav taws xob ua rau tsis tiav fusion ntawm vuam. Qhov teeb meem tau daws tom qab optimizing tus txheej txheem.
4. Kev siv cov Shielding Gas
Qhov tsim nyog shielding roj tuaj yeem tiv thaiv vuam oxidation thiab porosity. Argon, helium los yog lawv cov khoom sib tov yog feem ntau siv, thiab qhov ntws thiab tshuab kev taw qhia yuav tsum tau kho kom zoo. Kev tshawb fawb qhia tau hais tias argon ntws tus nqi ntawm 15 - 20 L / min thiab kev coj ua kom tsim nyog tuaj yeem txo qhov porosity.
Nyob rau hauv lub neej yav tom ntej, nws xav tias muaj zog dua thiab ntse dua laser vuam cov cuab yeej yuav tshwm sim, thiab cov txheej txheem vuam tshiab thiab cov ntaub ntawv tseem yuav txhawb nqa nws daim ntawv thov dav. Nyob rau hauv xaus, tsuas yog ua raws li cov kev ceev faj no, accumulating kev thiab optimizing tus txheej txheem yuav ua tau qhov zoo ntawm laser welding yuav tsum tau exerted los pab txhawb rau txoj kev loj hlob ntawm lub manufacturing kev lag luam.
