Lub hauv paus ntsiab lus ntawm kev soj ntsuam ultrasonic ntawm tuab-walled seamless steel kav yog hais tias lub ultrasonic sojntsuam yuav paub kev sib nrig sib hloov ntawm hluav taws xob zog thiab suab zog. Cov yam ntxwv ntawm lub cev ntawm ultrasonic tsis propagating nyob rau hauv elastic media yog lub hauv paus ntawm lub hauv paus ntsiab lus ntawm ultrasonic soj ntsuam ntawm steel kav. Lub directionally emitted ultrasonic beam generates ib tug reflected nthwv dej thaum nws ntsib ib tug tsis xws luag thaum propagation nyob rau hauv cov yeeb nkab steel. Tom qab qhov tsis xws luag cuam tshuam yoj yog khaws los ntawm ultrasonic sojntsuam, qhov tsis xws luag ncha teeb liab tau los ntawm kev ua haujlwm tsis zoo, thiab qhov tsis xws luag yog muab.

Txoj kev kuaj pom: Siv cov txheej txheem shear wave reflection los tshuaj xyuas thaum lub sij hawm sojntsuam thiab cov yeeb nkab steel txav mus rau ib leeg. Thaum lub sij hawm tsis siv neeg los yog phau ntawv tshuaj xyuas, nws yuav tsum tau xyuas kom meej tias lub suab beam scans tag nrho saum npoo ntawm cov yeeb nkab.
Qhov tsis xws luag nyob rau hauv longitudinal sab hauv thiab sab nrauv phab ntsa ntawm cov kav hlau steel yuav tsum tau soj ntsuam cais. Thaum tshawb xyuas qhov tsis xws luag ntawm longitudinal, lub suab beam propagates nyob rau hauv lub circumferential kev taw qhia ntawm cov yeeb nkab phab ntsa; Thaum kuaj xyuas qhov tsis xws luag, lub suab beam propagates nyob rau hauv cov yeeb nkab phab ntsa raws axis ntawm cov yeeb nkab. Thaum kuaj pom qhov ntev thiab qhov hloov pauv tsis xws luag, lub suab beam yuav tsum tau soj ntsuam hauv ob qho kev taw qhia ntawm cov yeeb nkab steel.

Cov cuab yeej kuaj xyuas qhov tsis zoo suav nrog cov mem tes qhia txog ntau lub channel lossis ib leeg-channel ultrasonic flaw detectors, uas nws qhov kev ua tau zoo yuav tsum ua raws li cov kev cai ntawm JB / T 10061, nrog rau kev sojntsuam, cov cuab yeej tshawb nrhiav, cov khoom siv sib kis, thiab cov khoom sib cais.
