Tmteck Angle Beam Transducers Chiyambi
Kuyendera kwa ngodya
Njira yozungulira (Shear Wave) imagwiritsidwa ntchito poyesa pepala, mbale, chitoliro, & ma welds. Mphero yapulasitiki imayikidwa pakati pa chinthu choyesera ndi transducer ndi kanema wa couplant pakati pa transducer ndi mphero. Mphero ya pulasitiki imalola mawu akumvekera kuti alowetse chinthu choyesera pangodya. Phokosolo limawonekeranso ku transducer monga poyesa mtengo wowongoka.
Kuyendera kwa ngodya ya 2
Kawirikawiri kuyezetsa mtengo wowongoka sikungapeze vuto. Mwachitsanzo, ngati chilemacho ndi chowongoka komanso chochepa thupi, sichimveka mawu okwanira kwa transducer kuti woyesayo adziwe kuti ulipo. Zikakhala chonchi, njira ina yoyeserera ndi ultrasound iyenera kugwiritsidwa ntchito. Njira ina yoyeserera ndi kuyesa kwapayipi. Kuyesa kwamakona a Angle kumagwiritsa ntchito zochitika zina kupatula madigiri a 90. Poyesa kulumikizana, pulasitiki wokhala ndi angled ndi malo pakati pa transducer ndi chinthu kuti apange mawonekedwe omwe angafune. Poyesa mtengo woloza pamakina omiza, pulasitiki siyofunikira chifukwa transducer imatha kungozingidwa m'madzi.

Ngati mawonekedwe azinthu asinthidwa kukhala china chilichonse kupatula madigiri a 90, mafunde akutali ndi mtundu wina wamawu amawu amapangidwa. Mafunde enawa amatchedwa mafunde akumeta ubweya. Chifukwa chakuti funde limalowa mozungulira, silimayenda lonse molunjika. Mamolekyu omwe ali mu chinthu choyesedwacho amakopeka wina ndi mnzake chifukwa zolimba zimakhala ndimphamvu yamagulu. Mamolekyu onyamula mawuwo amakopeka ndi mamolekyulu oyandikana nawo. Chifukwa cha ngodyayo, mamolekyulu omwe amanyamula mamodwayo amakoka mwa kukopa mphamvu mozungulira mozungulira kulowera kwa funde. Izi zimapanga mafunde akumeta ubweya, kapena mafunde omwe mamolekyulu awo amayenda molunjika komwe amalowera.
Kuyesa kwamakona a angle ndikusintha kwakuchulukiraku kumayambitsanso zovuta zina. Kumbukirani kuti funde likamafika pamwamba penipeni, limabwezeretsedwanso, kapena kuwerama, likalowa munjira yatsopanoyo. Chifukwa chake, mafunde akumeta ubweya ndi mafunde akutali adzachotsedwa mu chinthu choyesera. Kuchuluka kwa mawonekedwe kumatengera liwiro la phokoso m'mawayilesi awiri omwe mafunde akuyenda. Popeza liwiro la mafunde akumeta ubweya ndilocheperako kuposa liwiro la ma longitudinal mafunde, mawonekedwe awo obwezeretsa adzakhala osiyana. Pogwiritsira ntchito lamulo la Snell, titha kuwerengera momwe tingabwezeretse ngati tidziwa kuthamanga kwa mawu pazinthu zathu.
Ngodya imasankhidwa kuti iwonetsetse kuti mawuwo amapezeka pazolakwika zomwe akukayikira. Izi nthawi zambiri ndizomwe zimawononga kwambiri, mwachitsanzo kusowa kwa maphatikizidwe pamakoma azitsulo komanso pamizu, kapena ming'alu. Ma angles omwe amagwiritsidwa ntchito pazitsulo zazitsulo ndi awa:
a. 70 Wedge - 0.250 mpaka 0.750 mainchesi makulidwe
b. 60 Wedge - 0.500 mpaka 2.00 mainchesi makulidwe
c. 45 Wedge - 1.500 ndikukwera makulidwe
Ma probes omwe amagwiritsidwa ntchito pamakona ena amayenera kugwiritsidwa ntchito, kutengera pomwe cholakwacho chili pachiyeso, komanso milandu yapadera m'magawo ochepa. Mafupipafupi ayenera kukhala otsika mokwanira kuti apewe kuchepetsa kwambiri.
Angle Beam Transducers ndi wedges amagwiritsidwa ntchito poyambitsa mawonekedwe osunthira a shear mumayeso oyeserera. Njira yolumikizira bwino imalola kuti phokoso la mawu libwere kuchokera mbali, potero limathandizira kuzindikira zolakwika m'malo ozungulira ndi ozungulira.
