Ka nānā ʻana i ka pōʻino

1. ʻO ka NDT e pili ana i kahi ʻano hoʻāʻo no nā mea hana a i ʻole nā ​​​​mea hana i hōʻino ʻole a pili ʻole i kā lākou hana a hoʻohana paha.

2. Hiki i ka NDT ke loaʻa nā hemahema i loko a me ka ʻili o nā mea hana a i ʻole nā ​​mea hana, e ana i nā hiʻohiʻona geometric a me nā ana o nā mea hana, a e hoʻoholo i ka haku o loko, ka hale, nā waiwai kino a me ke kūlana o nā mea a i ʻole nā ​​​​mea hana.

3. Hiki ke hoʻohana ʻia ka NDT i ka hoʻolālā huahana, ke koho ʻana i nā mea waiwai, ka hana ʻana a me ka hana ʻana, ka nānā ʻana i ka huahana i hoʻopau ʻia, ka nānā ʻana i ka lawelawe (mālama), a me nā mea ʻē aʻe, a hiki ke pāʻani i kahi hana maikaʻi ma waena o ka mana maikaʻi a me ka hoʻemi ʻana i ke kumukūʻai. Kōkua pū ʻo NDT e hōʻoia i ka hana palekana a / a i ʻole ka hoʻohana pono ʻana i nā huahana.

Nā ʻano hana NDT

1. Loaʻa i ka NDT nā ala he nui i hiki ke hoʻohana pono. Wahi a nā loina kino ʻokoʻa a i ʻole nā ​​​​mea hoʻāʻo a me nā kumu, hiki ke hoʻokaʻawale ʻia ka NDT i kēia mau ʻano:

a) ʻano hoʻoheheʻe:

——X-ray a me ka gamma ray hoao ana;

——Ka hoao radiographic;

——Ka hoao ana i ka helu helu helu;

——Ka ho'āʻo radiographic Neutron.

b) ʻO ke ʻano acoustic:

——Ultrasonic hoao ana;

——Ka ho'āʻo ʻana i ka hoʻoheheʻe ʻana i ka leo;

——Electromagnetic acoustic hoao ana.

c) Keʻano electromagnetic:

——Eddy hoao ana;

——Ka ho'āʻo ʻana i ka leakage flux.

d) Keʻano o ka ʻili:

——Ka ho'āʻo ʻana i nā ʻāpana magnetic;

——Ka hoao ana i ka wai;

——Ka hoao ana.

e) Keʻano leakage:

——Hoao leak.

f) Keʻano infrared:

——Hoao wela infrared.

E hoʻomaopopo: hiki ke hoʻomohala ʻia a hoʻohana ʻia nā ʻano hana NDT hou i kēlā me kēia manawa, no laila ʻaʻole kāpae ʻia nā ʻano hana NDT ʻē aʻe.

2. ʻO nā ʻano hana NDT maʻamau e pili ana i nā ʻano NDT i hoʻohana nui ʻia a makua i kēia manawa. ʻO ia ka hoʻāʻo radiographic (RT), ka hoʻāʻo kani ultrasonic (UT), ka hoʻāʻo ʻana i kēia manawa (ET), ka hoʻāʻo ʻana i nā ʻāpana magnetic (MT) a me ka hoʻāʻo penetrant (PT).
