Umshini wokushisela we-laser ophethwe ngesandla uyimishini yokushisela impahla yensimbi evamile njengamanje, futhi ziyanda izimboni ziqala ukuthenga inombolo enkulu yemishini yokushisela i-laser ephathwa ngesandla ukuze isetshenziswe.Kodwa-ke, nakuba imishini ngokwayo inokusebenza okuhle kakhulu, la maphuzu amabili kufanele anakwe lapho usebenzisa umshini wokushisela we-laser ophethwe ngesandla.Ayini amaphuzu amabili?Ake sibheke!
Lawa maphuzu amabili kufanele aqashelwe lapho kusetshenziswa umshini wokushisela we-laser ophethwe ngesandla:
1, i-pulse waveform
I-Pulse waveform iyinkinga ebalulekile emshinini wokushisela we-laser ophethwe ngesandla, ikakhulukazi ekushiseleni kweshidi le-laser;Uma i-beam yokukhanya ephansi ifinyelela endaweni ebonakalayo, amandla athile endaweni yensimbi azohlakazwa futhi alahleke, futhi i-reflection coefficient izoshintsha ngokushintsha kwezinga lokushisa elingaphezulu.Phakathi nenkathi ye-pulse, ukubukeka kwensimbi kushintsha kakhulu, futhi ububanzi be-pulse bungenye yemingcele ebalulekile ye-laser welding.
2, ukuminyana kwamandla
Ukuminyana kwamandla kungenye ipharamitha eyisihluthulelo ku-laser welding.Ngaphansi kokuminyana kwamandla aphezulu, indawo ebonakalayo ingafinyelela endaweni ebilayo ngaphakathi kwama-microseconds, okubangele ukuncibilika okuningi.Ukuminyana kwamandla okuphezulu kulungele ukususwa kwezinto, njengokumba, ukuhlukaniswa kanye nokuqoshwa.Ngokuminyana kwamandla aphezulu, izinga lokushisa elingaphezulu lingafinyelela endaweni yokubilisa ngama-millisecond;Ngemva kokuba ubuso buncibilikisiwe umshini wokushisela we-laser ophethwe ngesandla, ungqimba olungezansi lufinyelela endaweni yokuncibilika ukuze kwakhiwe ukushisela okuhle kwe-fusion.Ngakho-ke, ku-insulator laser welding, ukuminyana kwamandla kungu-104~106Wcm2.Ukuminyana kwamandla maphakathi nendawo ye-laser kuphansi kakhulu ukuthi kungahwamuka kube yizimbobo.Endizeni eseduze nokugxilwe kwe-laser, ukuminyana kwamandla kunokulinganisa.Kunezindlela ezimbili zokususa ukugxila: ukuhlehlisa ukugxila okuhle nokubi.
Okungenhla amaphuzu ayinhloko okufanele anakwe lapho usebenzisa umshini wokushisela we-laser ophethwe ngesandla.Ngokuvamile, kufanele sisuse iphutha futhi siqinisekise la maphuzu amabili ngaphambi kokuwasebenzisa.Ukucubungula okusemthethweni kungenziwa kuphela ngemva kokulungisa iphutha nokuqinisekisa ukuthi alikho iphutha.
