Laser vuam ntawm aluminium alloy teeb meem 1: tsis tshua muaj laser nqus tus nqi ntawm aluminium alloy
Qhov teeb meem no feem ntau yog vim qhov teeb meem ntawm cov khoom siv aluminium alloy. Vim lub siab pib pom ntawm aluminium alloy rau laser beam thiab nws cov thermal conductivity, qhov nqus ntawm aluminium alloy rau laser ua ntej melting yog tsawg heev. Cov kev daws teeb meem no feem ntau suav nrog cov hauv qab no:
1. Nto pretreatment ntawm aluminium alloy cov ntaub ntawv. Xws li cov ntawv xuab zeb sib tsoo, tshuaj lom neeg etching, nto plating thiab lwm yam kev ntsuas pretreatment feem ntau siv hauv kev tsim khoom. Nce lub laser nqus tus nqi ntawm cov khoom.
2. Txo qhov chaw me me thiab ua kom lub zog laser ceev.
3. Hloov cov qauv vuam kom lub laser beam tsim ntau qhov kev xav hauv qhov sib txawv, uas yog yooj yim rau laser vuam ntawm aluminium alloy.
Aluminium alloy laser vuam teeb meem 2: yooj yim los tsim pores thiab kub tawg
Pores thiab kub tawg yuav yooj yim tshwm sim thaum lub sij hawm laser vuam ntawm txhuas alloys. Rau qhov teeb meem no, cov kev daws teeb meem feem ntau suav nrog cov hauv qab no:
1. Kho lub zog laser waveform nyob rau hauv cov txheej txheem vuam tuaj yeem txo qhov tsis ruaj khov ntawm qhov pores, hloov lub kaum sab xis ntawm laser beam irradiation thiab siv cov nyhuv ntawm magnetic teb nyob rau hauv vuam, thiab tseem tuaj yeem tswj cov pores generated thaum vuam.
2. Thaum siv YAG laser, lub mem tes waveform tuaj yeem hloov kho kom tswj tau cov cua sov nkag, kom txo tau cov kab nrib pleb.
Aluminium alloy laser vuam teeb meem 3: cov khoom siv ntawm welded pob qij txha poob
Kev kub hnyiab ntawm cov ntsiab lus alloy hauv cov txheej txheem vuam txo cov khoom siv ntawm aluminium alloy welded pob qij txha. Cov kev daws teeb meem no feem ntau suav nrog cov hauv qab no:
Cov khoom siv ntawm cov pob qij txha welded yog tshwm sim los ntawm cov pores tsis ruaj khov uas ua los ntawm aluminium alloy vuam. Aluminium alloy feem ntau suav nrog Zn, Mg thiab al. Thaum lub sij hawm welding, lub boiling point ntawm txhuas yog siab tshaj li ntawm ob lub ntsiab. Yog li ntawd, thaum welding aluminium alloy cov ntsiab lus, qee qhov qis boiling point alloy ntsiab tuaj yeem ntxiv, uas yog qhov tsim nyog rau kev tsim cov qhov me me thiab qhov ruaj khov ntawm vuam.
