Sayansi Yodziwika Kwambiri ya Maven Laser | Njira 10 Zodziwika Bwino Zowotcherera
- Kuwotcherera kwa Arc ya Chitsulo Chotetezedwa (SMAW)
Kuwotcherera arc yachitsulo chotetezedwa ndi chimodzi mwa luso lofunika kwambiri lomwe wowotcherera ayenera kukhala nalo. Kusadziwa bwino luso limeneli kumabweretsa zolakwika zosiyanasiyana mu msoko wowotcherera.
- Kuwotcherera kwa Arc Yoviikidwa M'madzi (SAW)
Kuwotcherera arc yoviikidwa m'madzi ndi njira yowotcherera yomwe imagwiritsa ntchito arc yamagetsi ngati gwero la kutentha. Imakhala ndi kulowa mozama, kupanga bwino kwambiri komanso mtundu wabwino kwambiri wa kuwotcherera: chitsulo chosungunuka chimachotsedwa mumlengalenga ndi chitetezo cha slag, ndipo ntchitoyi imayendetsedwa bwino kwambiri, zomwe zimapangitsa kuti ikhale yoyenera kuwotcherera mipata yayitali ya nyumba zapakati komanso zokhuthala.
- Kuwotcherera kwa Gasi Tungsten Arc (GTAW/TIG)
Nazi njira zofunika zodzitetezera ku GTAW:
(1) Nthawi zonse sungani electrode ya tungsten ikuthwa bwino. Electrode yosalala imayambitsa magetsi omwazikana komanso arc yosakhazikika, zomwe zingawononge chotchingira.
(2) Ngati electrode ya tungsten ili pafupi kwambiri ndi msoko wa weld, imamatira ku workpiece; ngati ili kutali kwambiri, arc idzabalalika, zomwe zimapangitsa kuti welds ikhale yakuda, electrode yotha msanga komanso kuwala kwamphamvu kwa wowotcherera. Ndi bwino kuyisunga pafupi momwe mungathere.
(3) Kuwongolera zoyambitsa ndi luso, makamaka pakuwotcherera mbale zopyapyala—kuwotcherera malo okha pakangopita nthawi yochepa. Mosiyana ndi makina owotcherera odzipangira okha omwe ali ndi waya wodzipangira okha komanso woyenda, kuwotcherera kosalekeza kumayaka mkati mwa chogwirira ntchito.
(4) Kudyetsa waya ndi manja kumafuna kumva bwino. Waya wowotcherera wabwino kwambiri ukhoza kudulidwa kuchokera ku mapepala 304 osapanga dzimbiri pogwiritsa ntchito makina odulira ubweya m'malo mogula waya wokhomedwa kale; waya wabwino wokhomedwa kale umapezeka kwa ogulitsa ambiri.
(5) Nthawi zonse muzigwira ntchito pamalo opumira bwino ndipo valani magolovesi achikopa, zovala zosayaka moto komanso chisoti chowotcherera chomwe chimazimitsa zokha.
(6) Gwiritsani ntchito nozzle ya ceramic ya tochi yowotcherera kuti mutseke kuwala kwa arc—makamaka, sungani kumbuyo kwa tochi kuyang'ana nkhope yanu momwe mungathere.
(7) Katswiri wowotcherera ali ndi chidziwitso chachilengedwe komanso kuzindikira kutentha, kukula, ndi momwe dziwe lowotcherera limagwirira ntchito.
(8) Ikani patsogolo kugwiritsa ntchito ma electrode a tungsten okhala ndi chizindikiro chachikasu kapena choyera, chifukwa amafunika luso lapamwamba lowotcherera.
- Kuwotcherera Gasi ndi Oxy-Fuel (OFW)
Kuwotcherera mpweya wa okosijeni kumagwiritsa ntchito lawi kutentha waya woyambira ndi waya wowotcherera pamalo olumikizirana a zitsulo, kuzisungunula kuti ziwotchere. Mpweya wamba wamafuta ndi monga acetylene, mpweya wa petroleum wosungunuka ndi haidrojeni, ndipo mpweya ndi womwe umapangitsa kuti okosijeni akhale wofunikira kwambiri.
- Kuwotcherera kwa Laser
Kuwotcherera ndi laser ndi njira yothandiza kwambiri komanso yolondola yowotcherera yomwe imagwiritsa ntchito kuwala kwa laser kokhala ndi mphamvu zambiri ngati gwero la kutentha, ndipo ndi njira yofunika kwambiri yogwiritsira ntchito ukadaulo wokonza zinthu za laser. M'zaka za m'ma 1970, imagwiritsidwa ntchito makamaka powotcherera zinthu zokhala ndi makoma ochepa komanso kuwotcherera mwachangu. Njira yowotcherera imayendetsedwa ndi conduction: kuwala kwa laser kumatenthetsa pamwamba pa workpiece, ndipo kutentha kwa pamwamba kumafalikira mkati kudzera mu conduction ya kutentha. Mwa kuwongolera magawo monga laser pulse width, mphamvu, mphamvu yapamwamba komanso kuchuluka kobwerezabwereza, workpiece imasungunuka kuti ipange dziwe linalake lowotcherera.
- Gas Metal Arc Welding (GMAW/MIG/MAG)
Owotcherera ambiri amaona kuti GMAW ndi njira yosavuta kwambiri yowotcherera chifukwa chakuti ndi yotchipa komanso yosavuta kuphunzira. Kawirikawiri, munthu watsopano amene alibe luso lowotcherera amatha kuwotcherera malo oyambira atatha maola awiri kapena atatu kuchokera kwa katswiri.
Mfundo zazikulu zophunzirira GMAW: khalani ndi dzanja lokhazikika, phunzirani kusintha kwa mphamvu yamagetsi ndi magetsi, lamulirani liwiro la kuwotcherera, ndikuphunzira machitidwe oyenera a manja (osavuta kuwapeza poonera mavidiyo). Kudziwa bwino njira yowotcherera kudzakuthandizani kuchita ntchito zambiri zowotcherera.
- Kuwotcherera kwa Mikangano
Kuwotcherera kwa friction ndi njira yomwe imagwiritsa ntchito kutentha komwe kumapangidwa ndi kukangana pamalo olumikizirana a workpieces ngati gwero la kutentha, zomwe zimapangitsa kuti pulasitiki isinthe zinthu zomwe zili pansi pa kukakamizidwa kuti zigwirizane ndi kuwotcherera.
Pakakhala kupanikizika kosalekeza kapena kuwonjezeka kwa mphamvu, kuyenda pakati pa mbali zolumikizirana ndi welding kumapangitsa kutentha kwa kukangana ndi kutentha kwa pulasitiki pamwamba ndi pafupi ndi kukangana, zomwe zimapangitsa kutentha kwa malowo kukhala pafupi koma nthawi zambiri pansi pa malo osungunuka. Izi zimachepetsa kukana kwa kapangidwe ka chinthucho, zimawonjezera pulasitiki ndikuswa filimu ya oxide pamalo olumikizirana. Pakakhala kupsinjika kosokoneza, limodzi ndi kusintha kwa pulasitiki ndi kuyenda kwa chinthucho, welding imachitika kudzera mu kufalikira kwa mamolekyulu ndi kubwezeretsanso kwa makristalo pamalo olumikizirana - zomwe zimapangitsa kuti ikhale njira yolumikizira yolimba.
Kuwotcherera kwa friction nthawi zambiri kumakhala ndi magawo anayi: (1) kusintha mphamvu ya makina kukhala mphamvu yotentha; (2) kusintha kwa pulasitiki kwa zinthuzo; (3) kupsinjika kwa mphamvu pansi pa mikhalidwe ya thermoplastic; (4) kufalikira kwa mamolekyulu ndi kubwezeretsanso mphamvu.
- Kuwotcherera kwa Akupanga
Kuwotcherera kwa ultrasonic kumatumiza mafunde ogwedezeka kwambiri pamwamba pa zinthu ziwiri zogwirira ntchito zomwe ziyenera kuwotcherera. Pansi pa kupanikizika, malo awiriwa amakokana kuti apange fusion pa molecular layer. Dongosolo lonse la ultrasonic welding makamaka limakhala ndi jenereta ya ultrasound, transducer, horn, welding nsonga assembly, nkhungu ndi chimango.
- Kusungunula Kofewa
Kusungunula ndi kusoka kumagwiritsa ntchito chitsulo chodzaza chomwe chili ndi malo otsika osungunuka kuposa chitsulo choyambira. Ma workpiece ndi chitsulo chodzaza amatenthedwa kufika kutentha pamwamba pa malo osungunuka a filler koma pansi pa malo osungunuka a chitsulo choyambira. Chitsulo chosungunula chodzaza chimanyowetsa chitsulo choyambira, chimadzaza malo olumikizirana ndikufalikira ndi chitsulo choyambira kuti chigwirizane ndi workpiece. Kusungunula ndi kusoka kumakhala ndi kusintha kochepa komanso malo olumikizirana osalala, okongola, zomwe zimapangitsa kuti zikhale zoyenera kulumikiza molondola, zigawo zovuta ndi ma assemblies opangidwa ndi zipangizo zosiyanasiyana (monga, mapanelo a uchi, masamba a turbine, zida zodulira za carbide zomangidwa ndi simenti ndi ma circuit board osindikizidwa). Kutengera kutentha kwa welding, brazing ndi soldering zimagawidwa m'magulu awiri: njira yokhala ndi kutentha kwa welding pansi pa 450℃ imatchedwa soldering yofewa, ndipo yomwe ili pamwamba pa 450℃ imatchedwa hard brazing.
