Mukugadzirwa kwemazuva ano, kushandiswa kwe2000W fiber laser welding michinaye welding aluminum metals iri kuramba ichipararira. Nekudaro, kuti ive nechokwadi chewelding mhando uye kuchengetedzeka, zvinotevera zvakakosha zvinhu zvinoda kucherechedzwa.
1. Kurapa kwepamusoro kusati kwaita welding
Iyo oxide firimu iri pamusoro pealuminium simbi inogona kukanganisa zvakanyanya kunaka kwewelding. Kunyatsogadziriswa kwepamusoro kunofanirwa kuitwa kubvisa iyo oxide firimu, mavara emafuta uye kumwe kusvibiswa. Kana imwe indasitiri yezvikamu zvemotokari yakasungirira furemu yealuminium, nekuda kwekuregererwa kwekugadziriswa kwepamusoro, huwandu hukuru hwemapores uye makatsemuka zvakaonekwa muweld, uye mwero wekufanirwa wakadzikira zvakanyanya. Mushure mekuvandudza nzira yekurapa, chiyero chekufanirwa chakakwira kusvika kupfuura 95%.
2. Kusarudzwa kweAkakodzera Welding Parameters
Welding paramita senge laser simba, welding kumhanya uye chinzvimbo chekutarisa zvakakosha zvikuru. Kune mahwendefa ealuminium ane hutema hwe2 - 3mm, simba re1500 - 1800W rinonyanya kukodzera; kune avo vane ukobvu hwe3 - 5mm, 1800 - 2000W yakakodzera. Iyo welding yekumhanyisa inofanira kufanana nesimba. Semuenzaniso, kana simba riri 1800W, kumhanya kwe5 - 7mm / s kwakanakira. Iyo yekutarisisa chinzvimbo inokanganisawo welding maitiro. Kutariswa kwemahwendefa matete kuri pamusoro, nepo kune makobvu mahwendefa, inoda kudzika mukati.
3. Kudzora kweKupisa Kupinza
Aluminium simbi ine yakakwira yekupisa conductivity uye inokurumidza kurasikirwa nekupisa, iyo inokanganisa weld kupinda uye simba. Kudzora kwakaringana kwekupisa kunodiwa. Semuyenzaniso, kana bhizinesi remuchadenga rakasonerwa zvikamu zvearuminiyamu, kusadzora zvakanaka kwekuisa kupisa kwakakonzera kusakwana kusanganiswa kweweld. Dambudziko rakagadziriswa mushure mekugadzirisa maitiro.
4. Kushandiswa kweShielding Gas
Yakakodzera kudzivirira gasi inogona kudzivirira weld oxidation uye porosity. Argon, helium kana misanganiswa yavo inowanzoshandiswa, uye chiyero chekuyerera uye kutungamira kwekuvhuvhuta kunofanirwa kugadziridzwa nemazvo. Tsvagiridzo inoratidza kuti argon kuyerera mwero we15 - 20 L/min uye kwakakodzera kuvhuvhuta gwara kunogona kuderedza porosity.
Mune ramangwana, zvinotarisirwa kuti epamusoro-simba uye akangwara akanyanya laser welding michina ichabuda, uye mitsva yewelding maitiro uye zvinhu zvinosimudzirawo kushanda kwayo kwakafara. Mukupedzisa, chete nekutevera idzi dziviriro, kuunganidza ruzivo uye optimize maitiro anogona zvakanakira laser welding zvinogona kuisirwa kubatsira mukusimudzira indasitiri yekugadzira.
