Hoʻāʻo hoʻopālahalaha
Pono e hoʻāʻo ʻia ka hoʻopālahalaha ʻana o nā paipu kila me ke anawaena waho ma mua o 22 mm a hiki i 400 mm, a ʻoi aku ka mānoanoa o ka paia ma mua o 10 mm. Ma hope o ka hoʻopālahalaha ʻia ʻana o nā laʻana
Hoʻāʻo kūlou
Pono e hoʻāʻo kūlou ʻia nā paipu kila me ke anawaena waho ʻaʻole i ʻoi aku ma mua o 22 mm. ʻO ke kihi kūlou he 90o. ʻO ke anawaena kūlou he 6 manawa o ke anawaena waho o ka paipu kila. Ma hope o ke kūlou ʻana i ka hāpana, ʻaʻole ʻae ʻia nā māwae a i ʻole nā māwae e ʻike ʻia ma ka hāpana.
Hoʻokolokolo macroscopic
No nā paipu kila i hana pololei ʻia e nā billets i hoʻolei mau ʻia a i ʻole nā ingots kila, pono ka ʻaoʻao hoʻolako e hōʻoia ʻaʻohe kiko keʻokeʻo, nā haumia, nā pehu ea ma lalo o ka ʻili, nā ʻāpana iwi poʻo a i ʻole ke kau ʻana ma luna o ka ʻiʻo macroscopic i hoʻopili ʻia me ka waikawa o ka billet a i ʻole ka paipu kila.
Nānā ʻana ʻaʻole luku
Wahi a ke noi a ka ʻaoʻao koi, a laila kūkākūkā ʻia ma waena o nā ʻaoʻao hoʻolako a me nā ʻaoʻao koi a hōʻike ʻia ma ka ʻaelike, hiki ke hana pākahi ʻia ka ʻike ʻana i nā kīnā ultrasonic no nā paipu kila. Pono ka hemahema lima lōʻihi o ka paipu laʻana kuhikuhi e hoʻokō i nā koi no ka māka ʻae ma hope o ka nānā ʻana C8 i kuhikuhi ʻia ma GB/T 5777-1996.
