Cov rays cuam tshuam nrog cov khoom thaum lawv nkag mus rau nws thiab lawv qhov kev siv zog yog attenuated los ntawm kev nqus thiab tawg. Lub degree ntawm kev siv attenuation nyob ntawm qhov attenuation coefficient ntawm cov khoom thiab lub thickness ntawm txoj kev los ntawm cov khoom. Yog tias muaj qhov tsis xws luag hauv ib feem ntawm cov khoom (cov qauv) tau teeb pom kev zoo, thiab qhov sib npaug ntawm cov khoom sib txawv ntawm qhov tsis xws li cov qauv, qhov siv ntawm cov kab hluav taws xob sib kis hauv cheeb tsam yuav txawv ntawm ntawm thaj chaw ib puag ncig, thiab ntev li ntev tau siv lub ntsuas ntsuas ntsuas qhov sib txawv ntawm qhov sib txawv ntawm cov kab hluav taws xob, cov yeeb yaj kiab tau muab tso rau hauv qhov chaw tsim nyog kom nkag mus rau lub teeb los ntawm cov kab hluav taws xob xa mus, thiab qhov tsis zoo yog tau los ntawm chav tsaus. ua. Qhov degree ntawm blackening ntawm txhua lub ntsiab lus ntawm qhov tsis zoo yog nyob ntawm tus nqi hluav taws xob raug, vim qhov tsis xws luag thiab qhov tsis zoo ntawm qhov siv ntawm cov kab hluav taws xob sib txawv, qhov sib thooj ntawm qhov tsis zoo yuav tshwm sim ntawm qhov dub ntawm qhov sib txawv. Thaum qhov tsis zoo yog muab tso rau ntawm lub teeb pom kev, cov duab sib txawv ntawm cov duab sib txawv ntawm qhov sib txawv ntawm qhov tsaus ntuj tuaj yeem pom, raws li tus neeg ntsuam xyuas tuaj yeem txiav txim qhov tsis zoo thiab ntsuas qhov zoo ntawm cov qauv.
Scope ntawm daim ntawv thov: muaj feem xyuam rau txhua yam hlau, cov ntaub ntawv uas tsis yog-hlau thiab cov ntaub ntawv sib xyaw ua ke; feem ntau dav siv nyob rau hauv vuam qhov chaw thiab castings.
(1) Cov duab pom ntawm qhov tsis xws luag tuaj yeem tau txais, qhov tseeb, thiab qhov ntsuas qhov ntev thiab qhov dav dav kuj yog qhov tseeb dua.
(2) Kev soj ntsuam cov txiaj ntsig raug kaw ncaj qha thiab tuaj yeem khaws cia rau lub sijhawm ntev.
(3) Kev kuaj pom ntau dua ntawm qhov tsis xws luag (porosity, slag entrapment, thiab lwm yam)
(1) Tsim nyog rau kev soj ntsuam ntawm nyias thickness ntawm workpiece tab sis tsis haum rau thicker workpieces.
(2) Rau qhov chaw tsis xws luag (xws li cov kab nrib pleb, unfused, thiab lwm yam), yog tias lub kaum sab xis ntawm lub koob yees duab tsis tsim nyog, nws yog qhov yooj yim kom tsis pom qhov pom.
(3) Nws yog ib qho nyuaj rau kev txiav txim siab txoj hauj lwm thiab qhov loj (qhov siab) ntawm qhov tsis xws luag nyob rau hauv thickness ntawm lub workpiece.
(4) Tus nqi kuaj xyuas yog siab thiab qeeb.
(5) Cov rays muaj teeb meem rau tib neeg lub cev.
