Kupambana kwachitsulo ndilaser kuwotchererazimadalira pa chiyambi chake chakuthupi. Mwachitsanzo, kuwunikira kwakukulu kumatha kusokoneza mphamvu ya laser, pomwe kutenthetsa kwakukulu kumataya kutentha mwachangu kuchokera kumalo owotcherera. Makhalidwe amenewa, limodzi ndi malo amene amasungunuka, zimasonyeza mmene chinthu chimayamwa bwino mphamvu kuti chipange chowotcherera champhamvu, cholondola.
Pano pali kuwonongeka kwa zitsulo wamba ndi momwe katundu wake amagwirira ntchito.
Laser Welding Carbon Steel
Chitsulo cha kaboni ndi aloyi wachitsulo wa kaboni wokhala ndi mpweya wofikira 2.1%. Mpweya wa kaboni ndiye chiwongolero chachikulu cha zinthu zake.
Chitsulo chochepa cha carbon(yosakwana 0.25% carbon) ndi ductile, yolimba, komanso yosavuta kuyika ndi kuwotcherera. Nthawi zambiri amagwiritsidwa ntchito ngati mapanelo amthupi, waya, ndi mapaipi.
Chitsulo chapakati cha carbon(0.25% mpaka 0.60% carbon) ndi yamphamvu komanso yolimba kuposa chitsulo chochepa cha carbon. Izi zimapangitsa kuti zikhale zoyenera pazinthu zomwe zimafuna mphamvu zambiri komanso kukana kuvala, monga magiya, shafts, ndi mawilo a njanji.
Chitsulo chapamwamba cha carbon(kuposa 0.60% ya carbon) ndi yamphamvu kwambiri komanso yolimba kwambiri mwa atatuwo, komanso ndi yocheperako komanso yolimba kwambiri. Kulimba kwake kumapangitsa kuti ikhale yabwino kwa zida zodulira, akasupe, ndi mawaya amphamvu kwambiri, koma pamafunika kugwiridwa mosamala pakuwotcherera kuti zisagwe.
Chitsulo cha kaboni ndichokwera kwambiri popanga, ndipo chimatengera kuwotcherera kwa laser mokongola.
Ubwino wake: Mumapeza ma welds amphamvu, ozama modabwitsa komanso kupotoza pang'ono. Liwiro ndi kuphatikiza kwakukulu, kukulitsa zokolola pafakitale.
Malingaliro: Kuzizira kofulumira kwa njira ya laser kungapangitse kuti weld brittle komanso sachedwa kusweka. Nthawi zina, kutenthetsa gawolo ndikofunikira kuti muchepetse kuziziritsa ndikuletsa zovuta.
Laser Welding Stainless Steel
Ichi ndi machesi opangidwa kumwamba. Kuwotcherera kwa laser ndiye njira yabwino kwambiri yopangira zitsulo zosapanga dzimbiri, makamaka m'mafakitole omwe amafunikira ukhondo.
Ubwino wake: Kutentha kotsika, kolunjika ndikopambana kwakukulu. Imateteza zitsulo zosapanga dzimbiri zosapanga dzimbiri popewa zomwe zimatchedwa "carbide precipitation." Izi zimapangitsa kuti pakhale ma weld oyeretsedwa mwa opaleshoni, ndichifukwa chake amatchuka kwambiri m'mafakitale azachipatala ndi zakudya.
Malingaliro: Zitsulo zodziwika bwino zosapanga dzimbiri, monga mndandanda wa 300 (mwachitsanzo, 304, 316), weld bwino kwambiri. Komabe, magiredi ena, monga mndandanda wa 400, amatha kukhala osalimba m'malo omwe amakhudzidwa ndi kutentha.
Laser Welding Aluminium
Kuwotcherera aluminium nthawi zonse kumakhala kovuta, koma kuwotcherera kwa laser kukusintha masewerawo.
Ubwino wake: Aluminiyamu ndi kondakitala wamkulu wa kutentha, kutanthauza kuti ndi kuwotcherera kwachikhalidwe, kutentha kumafalikira ndipo kumapangitsa kuti mbali yonse ikhale yopingasa. Mphamvu yolunjika ya laser komanso kutentha pang'ono kumathetsa vutoli, ndikuchepetsa kwambiri kupotoza.
Malingaliro: Aluminiyamu imawunikira kwambiri. Kuwala konyezimira kumatha kudumpha mtengo wa laser pomwepo. Kupambana kumadalira zinthu zingapo zofunika: kuyeretsa pamwamba popanda banga, mpweya wabwino wotchingira, komanso kugwiritsa ntchito laser yoyenera (mafiber lasers nthawi zambiri amakonda) kuwonetsetsa kuti mphamvuyo imalowa.
Laser Welding Titanium
Ngati mukufuna kuwotcherera titaniyamu, laser ndi imodzi mwa zida zanu zabwino kwambiri pantchitoyo.
Ubwino wake: Titaniyamu ndi chitsulo chogwira ntchito, kutanthauza kuti imayipitsidwa mosavuta ndi okosijeni mumlengalenga ikasungunuka, zomwe zimapangitsa kuti chitsulocho chikhale chofooka, chophwanyika. Kuthamanga kwa laser ndi kulondola kwake kumachepetsa nthawi yomwe chitsulo chimasungunuka ndikuwonekera, kuchepetsa chiopsezo cha kuipitsidwa ndi kuphulika.
Malingaliro: Monga ndi TIG kuwotcherera titaniyamu, muyenerabe kusamala kwambiri. Ukhondo wathunthu ndi kutetezedwa koyenera ndi mpweya wa inert (monga argon) sizingatheke.
Laser Welding Copper ndi Zitsulo Zina Zowunikira
Apa ndipamene kuwotcherera kwa laser kumakankhira malire a zomwe zingatheke.
Ubwino wake: Makina owotcherera a laser amatha kujowina zida zowunikira kwambiri ngati mkuwa, zomwe ndizovuta kwambiri kuwotcherera ndi njira ina iliyonse. Izi ndizofunikira kwambiri pamapulogalamu monga mabatire agalimoto yamagetsi (EV), pomwe mkuwa ndi aluminiyamu ziyenera kulumikizidwa.
Malingaliro: Izi ndi zinthu zaukadaulo. Kuwoneka bwino kwambiri komanso kutenthetsa kwamafuta kumatha kuwononga ma laser optics ngati sakuyendetsedwa bwino. Nthawi zambiri zimafunikira zida zapadera, limodzi ndi njira zapamwamba.
Kodi Lkutsanzira Laser kuwotcherera?
Ngakhale zimamveka ngati chida chozizwitsa, sizokwanira pa ntchito iliyonse. Ndikofunika kumvetsetsa zamalonda.
1.Mtengo Wokwera Woyamba: Makina opangira makina opangira laser ndi ndalama zambiri, zokwera mtengo kwambiri kuposa makhazikitsidwe achikhalidwe a MIG kapena TIG.
2.Zofunika Zophatikizana Zolimba: Monga tafotokozera, ma lasers amafunikira kukwanira bwino. Ngati mbali zanu zili ndi mipata kapena sizinadulidwe bwino, laser sangathe kuzimitsa bwino.
3.Nkhani za Reflectivity: Zida zonyezimira monga aluminiyamu ndi mkuwa zimatha kukhala zolimba kuti ziwotcherera popanda ma lasers apadera ndi luso.
4.Nkhawa Zachitetezo: Dongosolo lamphamvu kwambiri la laser ndi lowopsa kwambiri ndipo limatha kuvulaza maso kwambiri komanso kuyaka khungu, ngakhale pakuwunikira. Malo otetezedwa otetezedwa ndi zida zodzitetezera (PPE) ndizovomerezeka.
Zochita Zabwino Kwambiri Zopangira Zopanda Laser Welds
Kuti mupindule kwambiri ndi njira yanu yowotcherera laser, muyenera kukhomerera zoyambira.
Kukonzekera ndi Chilichonse
Joint Fit-Up: Sitinganene mokwanira: mbali zanu ziyenera kugwirizana mwamphamvu. Yesetsani kuti pakhale kusiyana kochepera 10% ya makulidwe azinthu kuti mupeze zotsatira zabwino.
Kuyeretsa Pamwamba: Chotsani chilichonse chomwe sichiri chitsulo. Izi zikutanthauza kuchotsa mafuta onse, mafuta, ma oxides, ndi zoipitsa zina zilizonse. Pamwamba paukhondo ndikofunikira kuti mupewe ma pores ndi zolakwika zina pakuwotcherera kwanu.
Sinthani Njira Yanu
Kuteteza Gasi: Monga TIG ndi MIG, kuwotcherera kwa laser kumagwiritsa ntchito mpweya wa inert (kawirikawiri argon kapena helium) kuteteza dziwe losungunuka kuchokera ku mpweya ndi nayitrogeni mumlengalenga, kuonetsetsa kuti kuwotcherera kwamphamvu, koyera.
Kukhathamiritsa kwa Parameter: Muyenera kuyimba pazokonda zanu. Mphamvu ya laser, liwiro la kuwotcherera, ndi mtunda wolunjika ziyenera kuyendetsedwa bwino ndi zinthu zenizeni komanso makulidwe omwe mukugwira nawo ntchito.
Chitetezo Choyamba, Nthawizonse
Kuwotcherera kwa laser si njira yomwe mungakhale wamba. Kuwala koyang'anako ndi kwamphamvu kwambiri. Aliyense amene ali pafupi ndi opaleshoniyo ayenera kuvala magalasi apadera otetezera laser omwe amavotera kutalika kwake kwa laser yanu.
Kodi Makina Owotcherera a Laser Ndi Njira Yoyenera Kwa Inu?
Ndiye, kodi muyenera kuyika ndalama pakuwotcherera kwa laser?
Tiyeni tibwereze. Laser kuwotcherera ndi chida chapamwamba chopangira chomwe chimapereka liwiro losayerekezeka, kulondola, komanso mtundu. Kusinthanitsa ndi mtengo wokwera woyambira komanso zofunika kwambiri pazigawo zoyera, zokwanira bwino.
Lingaliro lathu lomaliza: Ngati ntchito yanu ikufuna kuchuluka kwa voliyumu, makina odzipangira okha, komanso kulondola kwenikweni, makamaka pazinthu zosalimba kapena zovuta, ndiye kuti kuwotcherera kwa laser si njira ina. Ndilo yankho lapamwamba lomwe lingasinthire kupanga kwanu.
