Tmteck Angle Beam Transducers Selelekela
Mokhoa oa angle-beam (Shear Wave) o sebelisetsoa ho etsa lakane, poleiti, phala le li-welds. Sekhahla sa polasetiki se beoa lipakeng tsa ntho e lekiloeng le transducer ka filimi ea couplant lipakeng tsa transducer le chesele. Chesele ea polasetiki e lumella leqhubu la molumo ho kenya ntho ea liteko ka lehlakore. Kamore ea molumo e ntan'o bonahala ho transducer joalo ka ha ho etsoa liteko tse otlolohileng.
Hangata liteko tsa molamu o otlolohileng li ke ke tsa fumana sekoli. Ka mohlala, haeba sekoli se otlolohile ebile se otile ka ho lekaneng, se ke ke sa hlahisa molumo o lekaneng ho transducer ho tsebisa mohlahlobi hore e teng. Maemong a tjena, mokhoa o mong oa ho etsa liteko tsa ultrasound o lokela ho sebelisoa. Mokhoa o mong oa ho etsa liteko tsa ultrasound ke ho etsa liteko tsa boriti. Ho lekola toloki ea Angle ho sebelisa liketsahalo tse ling ntle le likhato tse 90. Ha ho etsoa tlhahlobo, ho na le polasetiki e nang le angled pakeng tsa transducer le ntho e ka etsang hore ho be le lehlakore le lakatsehang. Bakeng sa liteko tsa toloki ea maqhubu litsing tsa ho qoelisoa, polasetiki ha e hlokehe hobane transducer e ka ts'oaroa ka metsing feela.
Haeba boemo ba ketsahalo bo fetotsoe ho ba eng kapa eng ntle le likhato tse 90, maqhubu a longitudinal le mofuta oa bobeli oa leqhubu la molumo lia hlahisoa. Maqhubu ana a mang a bitsoa maqhubu a ho kuta. Hobane leqhubu le kene ka lehlakoreng, ha le tsamaee kaofela ka kotloloho ka har'a thepa. Limolek'hule tse nthong ea tlhahlobo li hohelana hobane lintho tse tiileng li na le maqhama a matla a limolek'hule. Limolek'hule tse tsamaisang molumo li hoheloa ke limolek'hule tse li potolohileng. Ka lebaka la sekhutlo, limolek'hule tse nang le molumo li huloa ke matla a hohela ka nqa e le 'ngoe ho ea ntlheng ea leqhubu. Sena se hlahisa maqhubu a ho kuta, kapa maqhubu ao limolek'hule tsa 'ona li tsamaeang ka mokhoa o ikhethileng ho ea lehlakoreng la leqhubu.
Ho lekoa ha toloki ea Angle le phetoho ea boemo ba liketsahalo le hona ho baka mathata a mang. Hopola hore ha leqhubu le thula holim'a metsi ka lehlakoreng le leng, le tla khuoa kapa le kobehe ha le kena mochining o mocha. Kahoo, maqhubu a ho kuta le maqhubu a longitudinal a tla qhekelloa nthong ea teko. Palo ea phepelo e its'etleha ka lebelo la molumo lipakeng tse peli tseo leqhubu le tsamaeang ho tsona. Kaha lebelo la maqhubu a ho kuta le lieha ho feta lebelo la maqhubu a longitudinal, maqhubu a tsona a ho fapanya a tla fapana. Ka ho sebelisa molao oa Snell, re ka bala leqhubu la ts'ebetso ha re tseba lebelo la molumo linthong tsa rona.
Ho khethoa sekhutlo ho netefatsa hore echo e fumanoa mefokolong e belaelloang. Hangata tsena ke liphoso tse kotsi ka ho fetesisa, mohlala, ho hloka fusion maboteng a litšepe le motso, kapa mapetsong. Li-angles tsa probe tse sebelisoang haholo bakeng sa botenya bo fapaneng ba tšepe ke tse latelang:
a. 70 Wedge - 0.250 ho 0.750 inches ka botenya
b. 60 Wedge - 0.500 ho 2.00 inches ka botenya
c. 45 Wedge - 1.500 ho ea holimo ka botenya
Mekhoa e sebetsoang ka mahlakore a mang e tlameha ho sebelisoa, ho ipapisitse le boemo ba phoso molemong oa liteko le bakeng sa linyeoe tse ikhethang likarolong tse tšesaane. Maqhubu a lokela ho ba tlase ka ho lekaneng e le ho qoba ho fokotsa ho feteletseng.
Angle Beam Transducers le li-wedge hangata li sebelisetsoa ho hlahisa leqhubu la shear le kentsoeng ka har'a thepa ea liteko. Tsela ea molumo oa angled e lumella molumo oa molumo hore o kene ka lehlakoreng, ka tsela eo o ntlafatsa bofokoli ba liphoso libakeng tse haufi le tse haufi.
