Mangani marudzi e laser welding aunoziva?

Zvakanakira uye Zvakaipa Laser Welding of Aluminium Alloy

Kana laser welding aluminium alloy, kungofanana nekuputirwa kwesimbi yesimbi, mapores mazhinji uye makatsemuka anogadzirwa panguva yekushongedza, izvo zvinokanganisa kunaka kwewelding.Aluminium element ine yakaderera ionization simba, yakashata welding kugadzikana, uye zvakare ichakonzera welding kusaenderera.Pamusoro peiyo yakanyanya kupisa welding nzira, aluminium oxide uye aruminiyamu nitride ichagadzirwa mukuita kwese, zvichikonzera kusvibiswa kune zvakatipoteredza.

Nekudaro, iyo aruminiyamu alloy plate pamusoro inogona kukwenenzverwa isati yaturika kuti iwedzere kutorwa kwayo kwelaser simba;Inert gasi rinozoshandiswa panguva yewelding kudzivirira maburi emhepo.

Laser arc hybrid welding yealuminium alloy yakagadzirisa matambudziko elaser welding simba, kunyura kwelaser beam pamusoro pealuminium alloy uye chikumbaridzo kukosha kwekudzika kwekupinda welding.Ndiyo imwe yeanonyanya kuvimbisa aluminium alloy welding process.Parizvino, maitiro haasati akura uye ari mudanho rekutsvagisa uye rekuongorora.

Kuoma kwelaser welding kwakasiyana kune akasiyana aluminium alloys.The vasiri kupisa kurapwa akasimbisa aruminiyamu uye aruminiyamu chiwanikwa 1000 dzakatevedzana, 3000 akatevedzana uye 5000 akatevedzana vane weldability yakanaka;4000 akatevedzana alloy ane yakaderera mutswe kunzwa;Kune 5000 series alloy, apo ω Apo (Mg) = 2%, alloy inobudisa mitswe.Nekuwedzera kwe magnesium yemukati, iyo welding performance inovandudzwa, asi iyo ductility uye corrosion kuramba inova murombo;2000 akatevedzana, 6000 akatevedzana uye 7000 akatevedzana alloys ane hunhu hwakakura hwekupwanya kupisa, kushata kuumbwa kwe weld, uye kudzikisira kwakakosha kwekuomarara kwemashure ekuchembera.

Naizvozvo, kune iyo laser welding yealuminium alloy, zvinodikanwa kutora matanho akakodzera ekuita uye kusarudza nemazvo nzira dzewelding uye maitiro kuti uwane yakanaka welding mhedzisiro.Pamberi pekuputira, kurapa kwepamusoro kwezvinhu, kutonga kweiyo welding process parameters uye shanduko yewelding chimiro inzira dzese dzinoshanda.

Kusarudzwa kwewelding parameters

· Laser simba 3KW.

· Laser welding kumhanya: 4m/min.Iyo welding yekumhanyisa inoenderana nekuwanda kwesimba.Iyo yakanyanya kuwanda kwesimba, ndiko kukurumidza kukurumidza kwewelding.

· Kana ndiro yacho yakabatiswa (senge 0.8mm yedivi remadziro rekunze ndiro uye 0.75mm yevhavha yekunze ndiro yekunze), gungano remvumo rinodzorwa nepakati, kazhinji 0.05 ~ 0.20mm.Kana iyo weld isingasviki 0.15 mm, iyo zinc vapor haigone kubviswa kubva kune gap rerutivi, asi inobviswa kubva kune weld surface, iyo iri nyore kugadzira porosity defects;Kana iyo weld yakakura kupfuura 0.15 mm, simbi yakanyungudutswa haigone kuzadza gap, zvichikonzera kusakwana kwesimba.Kana iyo weld yakakura yakafanana neiyo yeplate, iyo mechanical properties ndiyo yakanakisisa, uye weld width inoenderana nekutarisa dhayamita;Kudzika kwe weld kunoenderana nekuwanda kwesimba, welding kumhanya uye kutarisisa dhayamita.

· Iyo inodzivirira gasi ndeye argon, iyo inoyerera ndeye 25L / min, uye kushandiswa kwekushanda ndeye 0.15 ~ 0.20MPa.

· Focus dhayamita 0.6 mm.

· Kutarisisa chinzvimbo: kana kukora kweplate kuri 1mm, kutarisisa kuri pamusoro pepamusoro, uye chinzvimbo chekutarisa chinoenderana nechimiro chekoni.
