Kumu: Ma hope o ka ferromagnetic mea a me workpieces ua magnetized, ma muli o ke alo o ka discontinuities, ka magnetic kahua laina ma luna o ka ili a kokoke i ka ili o ka workpieces underlo local distortion, ka hopena i ka leakage magnetic mahina.Hoʻopili ʻia nā ʻāpana magnetic i hoʻopili ʻia i ka ʻili o nā mea hana, e hana ana i nā hōʻailona magnetic ʻike ʻia ma lalo o ke kukui kūpono, e hōʻike ana i ka wahi, ke ʻano, a me ka nui o nā discontinuities.
Hoʻohana a me nā palena:
He kūpono ka nānā ʻana i nā ʻāpana magnetic no ka ʻike ʻana i nā ʻoki ʻole ma ka ʻili a kokoke i ka ʻili o nā mea ferromagnetic i liʻiliʻi loa a loaʻa nā āpau haiki loa (e like me nā māwae hiki ke ʻike ʻia i ka lōʻihi o 0.1mm a me ka laulā o nā micrometers) he paʻakikī ke ʻike. ma ka maka;Hiki iā ia ke nānā i nā mea maka, nā huahana semi-finished, nā mea hana i hoʻopau ʻia, a me nā mea i loko o ka lawelawe, a me nā papa, nā profiles, nā paipu, nā kaola, nā ʻāpana welded, nā ʻāpana kila, a me nā ʻāpana kila forged.Hiki ke ʻike ʻia nā hemahema e like me nā māwae, hoʻokomo ʻia, nā lauoho, nā kiko keʻokeʻo, nā peʻa, nā pani anu, a me ka wehe.
Eia naʻe, ʻaʻole hiki ke ʻike ʻia ka hoʻāʻo ʻana i nā mea hoʻokalakupua austenitic stainless steel a me nā welds i welded me ka austenitic stainless steel electrodes, ʻaʻole hiki iā ia ke ʻike i nā mea non magnetic e like me ke keleawe, aluminika, magnesium, titanium, etc. , a me ka delamination a me ka pelu ʻana me kahi kihi ma lalo o 20 ° mai ka ʻili mea hana.
Hoʻāʻo Penetrant (PT)
Kumu: Ma hope o ka uhi ʻia ʻana o ka ʻili o ka ʻāpana me kahi penetrant i loaʻa ka fluorescent a i ʻole nā kala kala, ma lalo o ka hana a ka puʻupuʻu capillary, ma hope o kekahi manawa, hiki i ka penetrant ke komo i loko o ka wehe ʻana o ka ʻili;Ma hope o ka wehe ʻana i ka penetrant keu ma ka ʻili o ka ʻāpana, hoʻopili ʻia kahi mea hoʻomohala i ka ʻili o ka ʻāpana.Pēlā nō, ma lalo o ka hana a ka capillary, e huki ka mea hoʻomohala i ka penetrant i hoʻopaʻa ʻia i loko o ka hemahema, a e hoʻi hou ka penetrant i ka mea hoʻomohala.Ma lalo o kekahi kumu kukui (ultraviolet a i ʻole ke kukui keʻokeʻo), ʻike ʻia nā ʻāpana o ka penetrant i ka defect (fluorescence ʻōmaʻomaʻo melemele a i ʻole ʻulaʻula ʻulaʻula), no laila e ʻike ai i ka morphology a me ke kūlana hoʻoili o ka hemahema.
Nā pono a me nā palena:
Hiki i ka ho'āʻo Penetrant ke ʻike i nā mea like ʻole, me nā mea metala a me nā mea ʻole;ʻO nā mea magnetic a me nā mea magnetic ʻole;Welding, forging, rolling a me nā ʻano hana ʻē aʻe;Loaʻa i ka ʻike kiʻekiʻe (hiki ke ʻike ʻia he 0.1 μ M ākea ākea, me ka hōʻike intuitive, hana maʻalahi, a me ke kumukūʻai ʻike haʻahaʻa.
Akā hiki iā ia ke ʻike wale i nā hemahema me ka wehe ʻana o ka ʻili a ʻaʻole kūpono no ka nānā ʻana i nā mea hana i hana ʻia me nā mea porous a me nā mea paʻa a me nā mea hana me nā mea ʻala;Hiki ke ʻike ʻia ka puʻunaue ili o nā hemahema, e paʻakikī ai ka hoʻoholo ʻana i ka hohonu maoli o nā hemahema, e paʻakikī ana i ka loiloi quantitatively i nā hemahema.Hoʻopili nui ʻia nā hopena ʻike e ka mea hoʻohana.
