Hoʻohana mau ʻia nā ʻano hoʻāʻo ʻole luku nopaipu kila kalaponaʻo ia: ka hoʻāʻo kani ultrasonic (UT), ka hoʻāʻo ʻana i nā ʻāpana magnetic (MT), ka hoʻāʻo ʻana i ka wai penetrant (PT) a me ka hoʻāʻo ʻana o ka X-ray (RT).

ʻO ka hoʻohana ʻana a me nā palena o ka hoʻāʻo ultrasonic:
Hoʻohana nui ia i ka ikaika penetrability a me ka directionality maikaʻi o nā hawewe kani ultrasonic e hōʻiliʻili i ka noʻonoʻo ʻana o nā hawewe kani ultrasonic ma nā ʻano media like ʻole, a hoʻohuli i nā nalu hoʻopilikia i nā hōʻailona uila uila ma ka pale e ʻike ai i ka ʻike kīnā ʻole. Pōmaikaʻi: ʻaʻohe pōʻino, ʻaʻohe hopena i ka hana o ka mea i nānā ʻia, kiʻi pololei o ke ʻano o loko o nā mea opaque, kahi ākea o nā noi ʻike, kūpono no nā metala, non-metala, nā mea hoʻohui a me nā mea ʻē aʻe; ʻoi aku ka pololei o ke kūlana hemahema; ʻoluʻolu i nā hemahema ʻāpana, ʻike kiʻekiʻe, haʻahaʻa kumu kūʻai, wikiwiki wikiwiki, ʻaʻohe pōʻino i ke kino kanaka a me ke kaiapuni.

Ka palena: Pono nā hawewe kani ultrasonic e hilinaʻi ma luna o ka media a ʻaʻole hiki ke hoʻolaha i loko o kahi moena. Ua maʻalahi nā hawewe kani ultrasonic i ka nalowale a hoʻopuehu i ka lewa. ʻO ka mea maʻamau, pono ka ʻike ʻana i ka hoʻohana ʻana i nā couplants e hoʻopili i nā mea ʻike, a ʻo ka media e like me (ka wai deionized) he mea maʻamau.

ʻO ka hoʻohana ʻana a me nā palena o ka hoʻāʻo ʻana i nā ʻāpana magnetic:
1. He kūpono ka nānā ʻana i nā ʻāpana magnetic no ka ʻike ʻana i nā discontinuities liʻiliʻi ma ka ʻili a kokoke i ka ʻili o nā mea ferromagnetic, a he haiki loa a paʻakikī ke ʻike maka.
2. Hiki i ka nānā ʻana i nā ʻāpana magnetic ke ʻike i nā ʻāpana i nā kūlana like ʻole, a hiki ke ʻike pū i nā ʻano ʻāpana like ʻole.
3. Hiki ke loaʻa nā hemahema e like me nā māwae, nā mea hoʻokomo, nā lauoho lauoho, nā kiko keʻokeʻo, nā pelu, nā pani anu a me ka wehe.
4. ʻAʻole hiki ke ʻike ʻia ka hoʻāʻo ʻana i nā mea ʻeleʻele austenitic a me nā welds i hoʻopaʻa ʻia me nā electrodes stainless steel austenitic, ʻaʻole hiki ke ʻike i nā mea non-magnetic e like me ke keleawe, aluminika, magnesium a me ka titanium. He paʻakikī ka loaʻa ʻana o nā delamination a me nā pelu me nā ʻōpala pāpaʻu ma ka ʻili, kanu ʻia nā lua hohonu, a me nā kihi ma lalo o 20° me ka ʻili mea hana.

ʻO nā mea maikaʻi o ka ʻike penetrant: 1. Hiki iā ia ke ʻike i nā mea like ʻole; 2. He kiʻekiʻe kona naʻau; 3. Loaʻa iā ia ka hōʻike intuitive, hana maʻalahi a me ke kumukūʻai ʻike haʻahaʻa.
ʻO nā hemahema o ka hoʻāʻo penetrant: 1. ʻAʻole kūpono ia no ka nānā ʻana i nā mea hana i hana ʻia i nā mea hoʻoheheʻe porous a me nā mea hana me nā ʻili ʻōpala; 2. Hiki i ka ho'āʻo Penetrant ke ʻike wale i ka mahele o ka ʻili o nā hemahema, a paʻakikī ke hoʻoholo i ka hohonu maoli o nā hemahema, no laila paʻakikī ke ʻike i ka loiloi Quantitative o nā hemahema. Hoʻopili nui ʻia ka hopena ʻike e ka mea hoʻohana.

Hoʻohana a me nā palena o ka hoʻāʻo radiographic:
1. ʻOi aku ka maʻalahi i ka ʻike ʻana i nā hemahema ʻano leo, a ʻoi aku ka maʻalahi o ke ʻano o nā hemahema.
2. He mea maʻalahi ka mālama ʻana i nā mea ʻino radiographic a loaʻa ka traceability.
3. Hōʻike maka i ke ʻano a me ke ʻano o nā hemahema.
4. Nā pōʻino ʻAʻole hiki ke ʻike ʻia ka hohonu kanu o ka hemahema. I ka manawa like, ua kaupalena ʻia ka mānoanoa ʻike. Pono e holoi ponoʻia ke kiʻi maikaʻiʻole, a he meaʻino ia i ke kino o ke kanaka, a he kiʻekiʻe ke kumukūʻai.
