Raws li peb txhua tus paub, cov khoom siv aluminium alloy yog ib hom ntawm cov khoom tsis muaj kev txhim kho cov khoom siv dav hauv kev lag luam. Lub teeb yuag, tawv zoo thiab lub zog siab yog qhov zoo ntawm txhuas cov ntaub ntawv. Tam sim no, nws tau dav siv hauv aerospace, tsheb, tshuab kev lag luam thiab kev lag luam chemical. Yog li dab tsi yog cov txheej txheem welding ntawm aluminium alloy hauv laser vuam tshuab?
Aluminium alloy yog ib hom hlau tsis muaj hlau, uas muaj qhov cuam tshuam rau txhua yam ntawm lub teeb, thiab nws saum npoo yog yooj yim los ua refractory oxide zaj duab xis. Yog tias koj siv cov txheej txheem vuam tsoos, nws yog qhov yooj yim rau kev tsim cov kev tsis xws luag, xws li suav nrog, qhov hws, siv lead ua tawg thiab lwm yam. Raws li muaj zog ntom nti, cov kab teeb ci laser tau yooj yim dua rau ntawm qhov chaw ntawm aluminium alloy. Hauv lwm lo lus, tsis muaj hlau tsis muaj txhuas ntau qhov muaj qhov cuam tshuam siab thiab qhov qis qis rau kev nqus tau.
Txoj ntsiab cai ua haujlwm ntawm aluminium alloy laser vuam tshuab yog tias lub nqaj laser tau ua tiav raws li cov mem tes lossis nruam cov nqaj laser. Thaum lub laser nqaj ncaj qha irradiates saum npoo ntawm aluminium alloy, kub kub nyob rau saum npoo ntawm aluminium alloy tuaj yeem ceev nrawm rau sab hauv ntawm lub txhuas aluminium; tib lub sijhawm, cov tshuaj tiv thaiv tau tsim tawm ntawm cov hlau molten, thiab saum npoo ntawm molten aluminium alloy yog nias los tsim qhov me me.
Qhov zoo ntawm aluminium alloy laser vuam tshuab:
Kev kub siab lub zog, cov cua nkag qis, kev kho cua sov me me, nqaim nkag thaj tsam thiab thaj tsam cuam tshuam tshav kub, cua txias sai dua, qauv tawg zoo.
Piv nrog rau kev sib cuag vuam, lub tshuab ua lub laser vuam tsis tas yuav siv cov electrodes, yog li ntawd lub sijhawm ua haujlwm thiab tus nqi txo. Lub laser tuaj yeem xa cov ntaub ntawv raws li cov kab ke kho qhov muag hauv qhov ntev, uas ua rau cov txheej txheem yoog raws ntau dua. Tsis tas li ntawd, khoos phis tawj thiab kev ntsuas dag tuaj yeem siv los tswj cov vuam tshuab ua haujlwm tau sai thiab raug.
