Michina yesimbi yekuwachisa zvishongo zve laser yakagadzirwa uye yakagadzirwa nekambani yedu inoshandisa ceramic focusing cavities, inodzivirira ngura, inodzivirira kupisa kwakanyanya, uye inopa kugona kwakanyanya kwekuchinja kwe photoelectric. Focus cavity ne xenon lamp zvinogara kwenguva inopfuura mamiriyoni masere. Kubuda kwegasi rinodzivirira kunoita kuti welds dzifadze pasina oxidation kana kushanduka kweruvara. Muchina uyu unokwanisa kushanda maawa makumi maviri nemana pazuva, mazuva manomwe pasvondo, uye kushanda kwakasimba.

Kubatsira kweLaser welding nekudziisa munzvimbo diki kunoita kuti ishandiswe zvakanyanya mumaindasitiri akadai sezvishongo, mabhatiri, uye zvikamu zvefoni.

Kupinza neLaser kunoratidzwa nekusimba kwakanyanya kwekupinza, kumhanya nekukurumidza, uye mwero wakaderera wezvimedu zvemarara, zvichiita kuti ishandiswe zvakanyanya mukugadzira zvishongo zvemazuva ano. Mukugadzira zvishongo, ine mabhenefiti akasiyana pane matekinoroji ekare ekupinza:

1. Kumhanya Nekukurumidza, Simba Rakanyanya, Kushanduka Kushoma, Hapana Kutwasanudza kana Kuchenesa Mushure mekuWeldingChikonzero chikuru chinoita kuti vagadziri vezvishongo vashandise welding nelaser ndechekuti inokurumidza kumhanya uye kushanduka kushoma, zvichibvisa kudiwa kwekutwasanudza uye kuchenesa mushure mekuwelding. Kunyange zvazvo welding nelaser ichikurumidza kupfuura welding yemurazvo yechinyakare, vashandi vanowanzobata maworkpieces nemaoko kana kushandisa fixtures, vachiwelding chidimbu chimwe panguva. Nzvimbo zhinji dzekushandira dzezvishongo nelaser welding dzakatetepa, zvichideredza kugona kwekugadzirisa batch uye nguva yewelding inowedzera zvishoma. Zvisinei, nguva inochengetwa pakuchenesa inoripira zvizere izvi. Welding nelaser inogona kuitwa pasi pekuchengetedzwa kwegasi risina simba, isingasiyi mavara emoto pazvigadzirwa—zvichibvisa kudiwa kwekuyerera panguva yekuwelding uye acid pickling mushure mezvo. Kazhinji, welding nelaser inopa kushanda kwepamusoro kwekugadzira.

2. Yakakodzera maWorkpieces akakodzera, ichivimbisa Hunhu Hwakanaka

Beam relaser rinogona kunangidzirwa panzvimbo diki kuti rikwanise kuiswa zvakanaka, zvichiita kuti rive rakakodzera kugadzirwa otomatiki. Haringobatsiri chete pakushanda zvakanaka asi rinoderedzawo nzvimbo inokanganiswa nekupisa uye rinovimbisa kuti welds hadzina kusvibiswa, zvichiwedzera kunaka kwewelding uye zvinoderedza mwero wezvimedu. Semuenzaniso, zvishongo zve14K alloy (58% Au, 2% Ag) zvakasungirirwa neflame welding zvinogona kusangana neAg annealing, zvichideredza kuomarara kubva kuHv=145 nehafu - zvichikonzera maburi kana zvikadonhedzwa kubva pakukwirira kwechiuno. Kusiyana neizvi, welding yelaser ine simba shoma, inokurumidza kupinza kupisa, ichidzivirira workpiece annealing uye kuchengetedza simba rechimiro.

3. Kunyatsogadzirwa Kwazvo, Kugonesa Maitiro Ekugadzira Zvishongo Zvitsva Kuunzwa kwelaser welding muindasitiri yezvishongo kwakachinja mafungiro echinyakare ekugadzira. Zvinogonesa kugadzirwa kwezvishongo zvakagadzirwa nenzira yakasarudzika izvo zvaimbove zvakaoma kuwana kana kutadza kusangana nezvinodiwa zvemhando yepamusoro newelding yechinyakare. Laser welding inoshanda munzvimbo yakamanikana, zvichiita kuti zvive nyore kusanganisa zvinhu zvakasiyana-siyana zve alloy pasina kusanganisa—zvichibvumira ruvara rwakangoerekana rwaitika kana kuchinja kwechimiro pakati pezvikamu. Nzvimbo yayo yakamanikana yekushanda inoisiyanisa newelding yechinyakare maererano nekunyorova, kubatana kwakasimba, uye saizi yetsanga munzvimbo ine kupisa.

4.Kugadzikana Kwakanaka uye Kugadzikana

Kupinza neLaser kunowanzo batanidza zvakananga nekunyungudutsa maworkpiece emuno pasina chikonzero chekushandisa simbi dzekuzadza kana flux.

5.Inoita kuti basa rigadziriswe zviri nyore

Inogona kugadzirisa simbi pedyo nematombo anokosha, kubvisa maburi ari mumidziyo yakakandwa, uye kusundira nzvimbo dziri pedyo ne0.2mm kune zvinhu zvakaoma, zvinonzwa kupisa (semuenzaniso, mahinji, mahooks, maclasps, uye masettings).

6. Hushamwari hwezvakatipoteredza

Hapana zvinhu zvinosundidzira, zvinoyerera, kana zvekuchenesa zvemakemikari zvinodiwa panguva yekubatanidza ne laser, zvichibvisa matambudziko ekurasa marara.

7. Inoponesa Zvinhu zveSimbi

Kupinza simbi kwechinyakare kunoda ukobvu hwesimbi hushoma hwe0.2mm, nepo kupinza nelaser kunoderedza izvi kusvika ku0.1mm—zvichideredza huremu hwezvishongo ne35% ~ 40%, izvo zvakakosha zvikuru kune zvigadzirwa zvakagadzirwa nemagetsi. Kupinza nelaser kunochengetedza simbi dzinokosha uye dzinosungirirwa, uye kunobvisa kudiwa kwemhando dzakasiyana dzezvinobatanidza muzvikamu zvakasiyana-siyana zvekubatanidza.

8. Zvimiro zveMuchina weKey

Michina yekuwachisa zvishongo nelaser inowanzoshandiswa muindasitiri iyi ine simba shoma, zvichiita kuti ive yakachengeteka zvakanyanya. Ine dhizaini diki uye inotakurika, zvichibvumira vashandisi kushanda zvakanaka vakagara.
Michina yekucheka zvishongo zve laser yakajairikainogona kusanganisa simbi dzakawanda nema alloys nekukurumidza, zvakavimbika, uye nemazvo, kunyangwe kushanda zvakanaka kuchinyanya kuenderana nehunyanzvi hwechinhu chaunoda. Kugadziriswa kunoramba kuripo kana kugadzirwa kwe casting kunogona kuitwa ne laser pulses imwe chete kana kupfuura pasi pekutarisirwa kwekuona, uye pulse yega yega inogara 1 ~ 20ms. Stereomicroscopes uye crosshair alignment zvinogonesa kuisa nzvimbo chaiyo ye welding, zvichibvumira kugadziriswa kwakanaka kwenzvimbo yebasa mukati memunda wekuona. Welding inowanzoitwa mumamiriro ekunze; kupinza mhepo kana gasi risina simba munzvimbo yekushandira kunogona kutonhora, uye gasi risina simba rinowedzera kuvandudza kunaka kwe welding ye alloy.

9. Kupesvedzera kweAlloy Materials pakushanda kweLaser Welding
Zvinhu zvakasiyana-siyana zve alloy zvinopa mhedzisiro dzakasiyana-siyana dze laser welding. Pasi pema parameter akafanana emuchina uye pulse heat input, musiyano muhuwandu hwesimba rinopisa rinonyudzwa (zvichienzaniswa nerinoratidzwa) ne alloy surface unotungamira kune mhedzisiro dzakasiyana dzekunyunguduka pa pulse. Zvinhu zvikuru zvinopesvedzera zvinosanganisira kugona kupisa (kubva pakupisa kwemukamuri kusvika pakunyunguduka), melting point, latent heat of fusion, uye thermal conductivity. Kusiyana kwehunhu uhwu pazvinhu zvinokanganisa zvakanyanya simba rinodiwa kuti welding ibudirire—kukwana kwekupisa pamusoro pechinhu kwakakosha kuti welding ibudirire.
