ʻO ka hoʻāʻo non-destructive ka hoʻohana ʻana i nā hiʻohiʻona o ke kani, ka māmā, ka magnetism a me ka uila e ʻike inā he kīnā a i ʻole ka like ʻole o ka mea e nānā ʻia me ka ʻole o ka pōʻino a i ʻole ka hopena o ka hana o ka mea e nānā ʻia, a hāʻawi i ka nui. , kūlana, a me kahi o ka hemahema.ʻO ka huaʻōlelo maʻamau no nā ʻano loea āpau e hoʻoholo ai i ke kūlana ʻenehana o ka mea i nānā ʻia (e like me ke kūpono a ʻaʻole paha, ke koena o ke ola, etc.)
Hoʻohana pinepine ʻia nā ʻano hoʻāʻo hoʻāʻo ʻole: ka hoʻāʻo kani ultrasonic (UT), ka hoʻāʻo ʻana i ka ʻāpana magnetic (MT), ka hoʻāʻo wai penetrant (PT) a me ka hoʻāʻo X-ray (RT).
Ka ho'āʻo kani kani
ʻO UT (Ultrasonic Testing) kekahi o nā ʻano hana hoʻāʻo non-destructive ʻoihana.Ke komo ka hawewe kani ultrasonic i kekahi mea a loaʻa i kahi kīnā, e ʻike ʻia kekahi hapa o ka nalu kani, a hiki i ka mea hoʻouna a me ka mea hoʻokipa ke kālailai i ka nalu i hōʻike ʻia, a hiki ke ʻike pololei ʻia ka hemahema.A hiki iā ia ke hōʻike i ke kūlana a me ka nui o nā hemahema o loko, e ana i ka mānoanoa mea, etc.
Nā pōmaikaʻi o ka hoʻāʻo ultrasonic:
1. ʻO ka hiki ke komo nui, no ka laʻana, hiki i ka hohonu ʻike maikaʻi i ke kila ke piʻi aku ma mua o 1 mika;
2. No nā hemahema planar e like me nā māwae, interlayers, etc., ua kiʻekiʻe ka ʻike maka, a hiki ke ana ʻia ka hohonu a me ka nui o nā hemahema;
3. He mea lawe lima ka mea hana, palekana ka hana, a he maʻalahi ke hoʻomaopopo i ka nānā 'akomi.
hemahema:
ʻAʻole maʻalahi ka nānā ʻana i nā mea hana me nā ʻano paʻakikī, a ʻo ka ʻili e nānā ʻia e pono e loaʻa kahi ʻano o ka maʻalahi, a ʻo ke āpau ma waena o ka probe a me ka ʻili e nānā ʻia pono e hoʻopiha ʻia me ka couplant e hōʻoia i ka hoʻopili ʻana i ka acoustic.
Ho'āʻo Mākēneki
ʻO ka mea mua, e hoʻomaopopo kākou i ke kumumanaʻo o ka hoʻāʻo ʻana i nā ʻāpana magnetic.Ma hope o ka magnetized ʻana o ka mea ferromagnetic a me ka mea hana, no ka loaʻa ʻana o ka discontinuity, ua hoʻololi ʻia nā laina kahua magnetic ma ka ʻili a kokoke i ka ʻili o ka mea hana, e hopena i kahi leakage magnetic field, e hoʻomoʻi i ka pauka magnetic i kau ʻia ma ka ka ʻili o ka mea hana, a hana i kahi mākia ʻike ʻia ma lalo o ke kukui kūpono.nā meheu, e hōʻike ana i kahi, ke ʻano a me ka nui o ka hoʻopau ʻana.
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.
He kūlana maikaʻi loa ko Xinfa welding a me ka paʻa ikaika, no nā kikoʻī, e ʻoluʻolu e nānā:https://www.xinfatools.com/welding-cutting/
hoʻāʻo ʻana i ka wai
ʻO ke kumu kumu o ka hoʻāʻo ʻana i ka wai wai ma hope o ka uhi ʻia ʻana o ka ʻili o ka ʻāpana me nā dyes fluorescent a i ʻole nā kala kala, hiki i ka penetrant ke komo i loko o ka wehe ʻana o ka ʻili ma lalo o ka hana capillary no kekahi manawa;ma hope o ka wehe ʻana i ka mea komo nui ma ka ʻili o ka ʻāpana, ua hoʻopili ʻia ka mea hoʻomohala A i ka ʻili o ka ʻāpana.
Pēlā nō, ma lalo o ka hana a ka capillary, e huki ka mea kiʻi kiʻi i ka wai komo i hoʻopaʻa ʻia i loko o ka hemahema, a komo hou ka wai i loko o ka mea hana kiʻi, a ma lalo o kekahi kumu kukui (ke kukui ultraviolet a i ʻole ke kukui keʻokeʻo), ke ʻano o hōʻike ʻia ka wai komo i ka hemahema, (fluorescence melemele-'ōmaʻomaʻo a i ʻole ʻulaʻula ʻulaʻula), i mea e ʻike ai i ka morphology a me ka hāʻawi ʻana i nā hemahema.
ʻO nā mea maikaʻi o ka hoʻāʻo penetration:
1. Hiki iā ia ke ʻike i nā mea like ʻole;
2. Kiʻekiʻe sensitivity;
3. Hōʻike intuitive, hana maʻalahi a me ke kumukūʻai ʻike haʻahaʻa.
ʻO nā hemahema o ka hoʻāʻo ʻana i ke komo ʻana:
1. ʻAʻole kūpono ia no ka nānā ʻana i nā mea hana i hana ʻia i nā mea porous wehe a me nā mea hana me nā ʻili ʻōpala;
2. Hiki ke ʻike i ka hoʻāʻo ʻana i ka ʻili o nā hemahema, a paʻakikī ke hoʻoholo i ka hohonu maoli o nā hemahema, no laila paʻakikī ke hana i ka loiloi quantitative o nā hemahema.Hoʻopili nui ʻia ka hopena ʻike e ka mea hoʻohana.
Nānā X-ray
ʻO ka mea hope loa, ʻo ka ʻike kukui, no ka mea e nalowale ana nā kukui X ma hope o ka hele ʻana i ka mea i hoʻomālamalama ʻia, a ʻo nā mea like ʻole me nā mānoanoa like ʻole he ʻokoʻa ka absorption rate no lākou, a kau ʻia ke kiʻi ʻino ma kēlā ʻaoʻao o ka mea irradiated. ʻokoʻa ia ma muli o nā ʻokoʻa o nā kukuna.Hoʻokumu ʻia nā kiʻi e pili ana, a hiki i nā mea loiloi ke hoʻoholo inā he kīnā i loko o ka mea a me ke ʻano o ka hemahema e like me ke kiʻi.
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. ʻO ka hemahema, 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.
ʻO nā mea a pau, kūpono ke kani ultrasonic a me ka X-ray no ka ʻike ʻana i nā hemahema o loko;i waena o lākou, kūpono ke kani ultrasonic no nā ʻāpana me ke ʻano maʻamau o ʻoi aku ma mua o 5mm, a ʻaʻole hiki i nā kukui X ke ʻimi i ka hohonu kanu o nā hemahema a loaʻa i ka radiation.ʻO ka ʻāpana magnetic a me ka hoʻāʻo penetrant kūpono no ka ʻike ʻana i nā hemahema o ka ʻili o nā ʻāpana;i waena o lākou, ua kaupalena ʻia ka hoʻāʻo ʻana i nā mea magnetic i ka ʻike ʻana i nā mea magnetic, a ua kaupalena ʻia ka hoʻāʻo penetrant i ka ʻike ʻana i nā hemahema o ka wehe ʻana o ka ʻili.
