He aha ka NDT ʻoihana a me XRAY

NDT ʻOihana (Hoʻāʻo ʻAʻole Luku)
ʻO ka NDT ʻOihana e pili ana i kahi hoʻonohonoho o nā ʻano loea i hoʻohana ʻia i ka ʻoihana e ʻike, loiloi, a kālailai i nā hemahema kūloko a i ʻole ka ʻili, nā waiwai o nā mea, a i ʻole ke kūpaʻa o ke kūkulu ʻana o nā ʻāpana a i ʻole nā ​​​​mea me ka ʻole o ka hōʻino ʻana i ka mea i hoʻāʻo ʻia. Hoʻohana nui ʻia ia i ka hana ʻana, aerospace, ikehu, metallurgy, kūkulu ʻana, a me nā ʻoihana ʻē aʻe e hōʻoia i ka maikaʻi o ka huahana, pale i nā ulia, a hōʻemi i nā kumukūʻai.

Nā Hana NDT ʻOihana Maʻamau:

1. Hoʻāʻo Ultrasonic (UT)
   • Hoʻohana i nā nalu kani alapine kiʻekiʻe e ʻike i nā hemahema kūloko (e like me nā māwae, nā hakahaka) ma ke kālailai ʻana i nā hōʻailona i hōʻike ʻia.
   • Kūpono no nā mea mānoanoa a me nā ʻāpana metala.
2. Hoʻāʻo Radiographic (RT)
   • Hoʻokomo pū ʻia ka hoʻāʻo ʻana o ka X-ray a me ka gamma-ray. Hoʻohana i ka radiation electromagnetic (X-rays) e komo i loko o nā mea a hana i nā kiʻi o nā ʻano kūloko ma nā kiʻiʻoniʻoni a i ʻole nā ​​​​mea ʻike kikohoʻe.
   • Loaʻa ka maikaʻi no ka ʻike ʻana i nā hemahema e like me nā māwae, nā inclusions, a me nā kīnā kuʻihao.
3. Hoʻāʻo ʻĀpana Magnetic (MT)
   • Hoʻopili i nā kahua magnetic e magnetize i nā mea ferromagnetic. Hōʻike ʻia nā hemahema o ka ʻili a kokoke paha i ka ʻili e nā ʻāpana magnetic e hōʻiliʻili ana ma nā wahi kīnā.
   • Hoʻohana pinepine ʻia no ka nānā ʻana i nā ʻāpana kila.
4. Hoʻāʻo Penetrant (PT)
   • Hoʻopili kēia i ka hoʻopili ʻana i kahi penetrant wai i ka ʻili. Hoʻopili nā hemahema i ka penetrant, a laila e ʻike ʻia me ka hoʻohana ʻana i kahi mea hoʻomohala e hōʻike i nā kīnā e wāwahi ana i ka ʻili.
   • He kūpono no nā mea palupalu ʻole e like me nā metala a me nā plastics.
5. Hoʻāʻo ʻana o ke au Eddy (ET)
   • Hoʻohana i ka hoʻokomo electromagnetic e ʻike i nā hemahema o ka ʻili a i ʻole ka lalo o ka ʻili i nā mea alakaʻi. Hōʻike nā loli i nā ʻano o ke au eddy i nā hemahema.
   • Hoʻohana nui ʻia i nā ʻoihana aerospace a me nā ʻoihana kaʻa.

X-Ray ma ka NDT ʻOihana

Nā Kumumanaʻo:

• Hoʻokomo nā kukuna X i loko o ka mea i hoʻāʻo ʻia, a emi iho ko lākou ikaika ma muli o ka mānoanoa a me ka mānoanoa o ka mea.
• ʻIke ʻia nā kīnā (e like me nā hakahaka, nā māwae, a i ʻole nā ​​​​mea ʻē) ma ke ʻano he aka ʻokoʻa ma ka mea kiʻi (kiʻiʻoniʻoni a i ʻole ka mea ʻike kikohoʻe) ma muli o nā ʻano like ʻole o ka omo ʻana.

Nā noi:

1. Nānā Weld
   • Ke ʻike ʻana i ka fusion piha ʻole, ka porosity, a i ʻole nā ​​​​​​slag inclusions i loko o nā welds.
2. Nā ʻĀpana Aerospace
   • Ke nānā ʻana i nā ʻāpana turbine, nā ʻāpana mīkini, a me nā mea i hui pū ʻia no nā hemahema huna.
3. Ka Mana Hoʻokele Hana Hana
   • Ke hōʻoia nei i ka pono o ka hoʻolei ʻana a i ʻole ka hoʻoheheʻe ʻana ma ka ʻike ʻana i nā hemahema kūloko.
4. Nānā ʻana i ka Paipu a me ka Ipu Paʻi
   • Ke loiloi nei i ka kūpaʻa o ke ʻano o nā paipu a me nā pahu me ka ʻole o ka wehe ʻana.

Nā Pōmaikaʻi:

• Hāʻawi i nā moʻolelo ʻike maka mau loa (radiography) no ka palapala a me ka nānā hou ʻana.
• Kūpono no nā mea mānoanoa a me nā geometries paʻakikī.
• Hiki ke ʻike i nā hemahema o loko a me nā hemahema o loko.

Nā Palena:

• Pono nā hana palekana koʻikoʻi (e like me ka pale ʻana i ka radiation) ma muli o nā pilikia olakino mai ka hoʻolōʻihi ʻana.
• ʻAʻole kūpono no nā mea haʻahaʻa haʻahaʻa (e like me nā plastics) ke ʻole e hoʻohana ʻia nā ʻano hana kūikawā.
• ʻOi aku ke kiʻekiʻe o nā lako hana a me nā kumukūʻai hana i hoʻohālikelike ʻia me kekahi mau ʻano NDT ʻē aʻe.

Nā ʻokoʻa koʻikoʻi ma waena o ka NDT a me ka hoʻāʻo X-Ray:
