Ultrasonic welding inzira yeindasitiri umo ma-high-frequency ultrasonic acoustic vibrations anoiswa munharaunda kune zvidimbu zvebasa zviri kubatwa pamwechete pasi pekumanikidzwa kugadzira yakasimba-state weld.Inowanzoshandiswa mapurasitiki nesimbi, uye kunyanya kujoina zvinhu zvakasiyana.Mune ultrasonic welding, hapana mabhaudhi anobatanidza, zvipikiri, zvekushongedza zvinhu, kana zvinonamira zvinodikanwa kuti zvisunge zvinhu pamwechete.Kana yaiswa kune simbi, chinocherechedzwa hunhu hweiyi nzira ndechekuti tembiricha inogara iri pazasi pekunyungudika kwezvinhu zvinosanganisirwa nekudaro kudzivirira chero zvinhu zvisingadiwe zvinogona kusimuka kubva pakufumurwa kwekushisa kwakanyanya kwezvinhu.
Kujoinha majekiseni akaomarara akaumbwa thermoplastic zvikamu, ultrasonic welding michina inogona kugadziridzwa zviri nyore kuti ikwane izvo chaizvo zvakatemwa zvezvikamu zviri welded.Zvikamu zvakasungirirwa pakati pedendere rakagadziriswa (anvil) uye sonotrode (nyanga) yakabatanidzwa kune transducer, uye ~ 20 kHz low-amplitude acoustic vibration inobudiswa.(Cherechedza: Mafaro akajairika anoshandiswa mu ultrasonic welding ye thermoplastics i15 kHz, 20 kHz, 30 kHz, 35 kHz, 40 kHz uye 70 kHz).Kana welding mapurasitiki, chimiro chezvikamu zviviri zvakagadzirirwa kutarisisa maitiro ekunyunguduka.Imwe yezvigadzirwa kazhinji ine spiked kana yakatenderedzwa simba director inobata chikamu chechipiri chepurasitiki.Iyo ultrasonic simba inonyungudutsa iyo poindi yekubatana pakati pezvikamu, kugadzira mubatanidzwa.Iyi nzira yakanaka otomatiki imwe nzira yeglue, screws kana snap-fit dhizaini.Inowanzo shandiswa nezvikamu zvidiki (semuenzaniso nharembozha, zvemagetsi zvevatengi, maturusi ezvokurapa anoraswa, matoyi, nezvimwewo) asi inogona kushandiswa pazvikamu zvakakura kunge diki diki yemudziyo wemotokari.Ultrasonics inogona zvakare kushandiswa kukwenenzvera simbi, asi kazhinji inogumira kune madiki welds ematepi, anogadzika simbi, eg aluminium, mhangura, nickel.Ultrasonics yaisazoshandiswa muwelding chassis yemota kana muwelding zvidimbu zvebhasikoro pamwechete, nekuda kwemazinga emagetsi anodiwa.
Ultrasonic welding ye thermoplastics inokonzera kunyunguduka kwepurasitiki kwepanzvimbo nekuda kwekutorwa kwesimba rekudengenyeka pamwe chete nejoini kuti rive welded.Mune simbi, welding inoitika nekuda kwekunyanya-kudzvanywa kupararira kwepamusoro oxides uye kufamba kwenzvimbo kwezvinhu.Kunyange zvazvo kune kupisa, hazvina kukwana kunyungudutsa zvinhu zvepasi.
Ultrasonic welding inogona kushandiswa kune ese mapurasitiki akaoma uye akapfava, akadai semicrystalline mapurasitiki, uye simbi.Kunzwisisa kwe ultrasonic welding kwakawedzera nekutsvagisa uye kuyedzwa.Iko kugadzirwa kwemidziyo yakaoma uye isingadhuri uye kuwedzera kudiwa kwepurasitiki nemagetsi zvinhu zvakakonzera kukura kweruzivo rweiyo yakakosha maitiro.Nekudaro, akawanda maficha e ultrasonic welding achiri kuda kwakawanda kudzidza, senge ane chekuita weld mhando kugadzirisa ma paramita.Ultrasonic welding inoenderera mberi iri kukurumidza kukura munda.
