Revolution ye Welding Technology |Laser Welding yeAluminium Alloy
Aluminium alloys anoshandiswa zvakanyanya mumhando dzakasiyana-siyana dzakasungirirwa zvigadzirwa nekuda kwehuremu hwadzo huremu, kusimba kwepamusoro, yakanaka corrosion resistance, non-magnetic properties, good formability uye yakanaka yakaderera tembiricha kuita.Kana welding nearuminiyamu alloys, huremu hwewelded structural product inogona kudzikiswa ne50% kana ichienzaniswa neayo akaiswa mundiro dzesimbi.Parizvino, izvi zvave kushandiswa zvakanyanya mumaindasitiri akasiyana siyana sendege, aerospace, mota, bhatiri remagetsi, kugadzira michina, kuvaka ngarava, magonhi nemahwindo, indasitiri yemakemikari uye zvinodiwa zvezuva nezuva.
Yepamberi laser welding tekinoroji yealuminium alloy
Laser welding tekinoroji yealuminium alloy tekinoroji nyowani yakagadzirwa mumakore gumi apfuura.Iyo inoratidzira yekushanda kwakasimba, kuvimbika kwepamusoro uye kushanda kwakanyanya mukuenzanisa neyechinyakare welding nzira.Hezvino zvakanakira laser welded aluminium alloys:
▪ Kuwanda kwesimba remagetsi, kupisa kwakaderera, kuderera kwekushisa, nzvimbo yakamanikana yekunyunguduka uye nzvimbo inokanganisa kupisa uye kudzika kukuru kwekunyunguduka.
▪ Microfine weld chimiro nekuda kwekutonhora kwakanyanya uye kushanda kwakanaka kwemajoini.
▪ Laser welding pasina maelectrode, kuderedza vanhu-maawa uye mari.
▪ Chimiro chewelded workpiece haina kukanganiswa ne electromagnetism uye haiburitse X-rays.
▪ Kugona kupinza zvinhu zvesimbi mukati mezvinhu zvakavharwa zvinoonekera.
▪ Laser inogona kutapurirwa madaro marefu neoptical fibers, iyo inoita kuti nzira yacho ienderane.Nemakomputa uye marobhoti, iyo welding process inogona kuita otomatiki uye kunyatsodzorwa.
Zvakanakira kubata nearuminiyamu yakagadziriswa kupisa
Wedzera kumhanya kwekugadzirisa
Wedzera kugona kwekugadzira uye kuvandudza kunaka kwewelding nekudzikisa zvakanyanya kupinza kwekupisa.
Kana welding yakakwirira-simba uye yakakura-ukobvu aruminiyamu alloys, inogona nyore kuwana welding kuburikidza mune imwe chete pass nekugadzira yakakura kudzika kwekiiyi umo laser yakadzika fusion welding uye keyhole mhedzisiro inoitika, iyo yakasimba kupfuura yechinyakare welding nzira.
Kuenzanisa kweyakajairwa laser sosi mune laser welding yealuminium alloys
Mazuva ano, iwo makuru laser masosi anoshandiswa mumusika CO2 laser, YAG laser uye fiber laser.Nekuda kwekuita kwayo kwepamusoro-simba, CO2 laser inonyanya kukodzera kune gobvu plate welding, asi mwero wekunyudzwa kweCO2 laser beam pamusoro pearuminiyamu alloy idiki, izvo zvinokonzeresa kurasikirwa kwesimba rakawanda panguva yewelding process.
YAG laser inowanzoita idiki musimba, kunyura kweYAG laser beam pamusoro pealuminium alloy yakakura kupfuura iyo CO2 laser, inowanikwa optical fiber conduction, kuchinjika kwakasimba, kurongeka kwemaitiro, nezvimwewo, iyo yakashata yeYAG: iyo simba rekubuda uye photoelectric kutendeuka simba rakaderera.
Fiber laser ine zvakanakira saizi diki, mutengo wakaderera wekushandisa, hupenyu hurefu hwesevhisi, kugadzikana kwakanaka uye yakakwirira danda mhando.Zvichakadaro, mwenje unoburitswa nefiber laser ndeye 1070nm wavelength ine yakakwira kunyudzwa mwero, photoelectric conversion rate yakakwira kagumi pane YAG laser, uye kumhanya kwewelding inokurumidza kupfuura YAG uye CO2 laser.
Welding Technology Revolution
Yakakwira simba laser welding michina inotarisirwa kuiswa mualuminium alloy welding
Seyakakwira-simba-density welding process, laser welding inogona kudzivirira zvinokanganisa hurema hunokonzerwa nemaitiro echinyakare welding, uye welding simba coefficient ichavandudzwa zvakanyanya.Zvichiri kunetsa kushandisa yakaderera-simba laser welding muchina weld aluminium alloy gobvu mahwendefa, kwete chete nekuti kunyudzwa kweiyo laser beam pane aluminium alloy pamusoro yakadzikira, asi zvakare kuchine dambudziko rechikumbaridzo raivepo kana zvichidikanwa. welding yakadzika yekupinda.
Chinhu chinonyanya kubata ziso chealuminium alloy laser welding muchina ndeyekunyanya kushanda kwayo, iyo inoshandiswa kune yakakura-yakadzika-yakadzika-yekupinda welding kuti ishandiswe.Uye iyi yakakura-yakadzika-yakadzika-yekupinda welding tekinoroji ichave isingadzivisike budiriro mune ramangwana.Neimwe nzira, uku kudzika kwakadzika kwemukati welding inosimbisa chiitiko chepinhole uye kukanganisa kwayo pane weld porosity, iyo inoita kuti magadzirirwo epinhole aite uye kutonga kwayo kuve kwakanyanya kukosha, uye ichave yechokwadi shanduko mune welding nyika mune ramangwana.
