I mea e mahalo ai i ka maikaʻi o nā kaula kila i hoʻopaʻa ʻia, hiki ke kiʻi ʻia kēia mau hoʻoholo.
1. ʻIkepili hoʻohui kemika
Nānā Maʻiʻo o C, Si, Mn, P, S, etc. ma Rebar
Pono e hoʻokō ka hui kemika me ASTM, GB, DIN a me nā kūlana ʻē aʻe.
2. Hoao hana mechanical
Hōʻike ka hoʻāʻo ʻana i ka tensile i ka ikaika tensile, yield strength, compression zone, etc.
ʻO ka hoʻāʻo paʻakikī ʻo Rockwell a i ʻole Vickers.
Pono e hahai ʻia nā pae hoʻokō mechanical i kuhikuhi ʻia i nā kūlana kūpono.
3. ʻIke metala
E nānā i ka laʻana i loko o ka mea hoʻohālikelike metallographic e nānā i nā hemahema a me nā laʻana maikaʻi ʻole.
Pono ke ʻano o ke ʻano maʻemaʻe, ʻaʻahu like ʻole, ʻaʻohe māwae a me nā hoʻokomo haole.
4. E nānā i ka maikaʻi o ka pūnaewele.
E nānā i ka hiʻohiʻona, ka maikaʻi o ka ʻili, ka pōʻino mechanical, nā māwae, nā niho, etc.
Hoʻohana ʻia ʻo Ra no ka ʻike ʻana i ka ʻili o ka ʻili
5. Huli i ke ano
Hoʻohana ʻia nā jigs a me nā mea paʻa e nānā i nā ʻāpana e like me ka maikaʻi metala, kani a me nā ʻae.
E nānā i nā hemahema, pōʻino, deformation, etc.
E like me nā kūlana aupuni a me nā ʻoihana
6. ʻO ka hoʻāʻo ʻole luku
Hoʻāʻo ʻia ka ʻili a me ka loko e ke ʻano penetrant wai a i ʻole ke ʻano ʻāpana magnetic.
No laila, inā paha e hoʻokō nā hopena hōʻike i nā koi o ke kūlana ʻoihana hiki ke hana i kahi loiloi maikaʻi o ka rebar.Pono kēia i ka hoʻohanaʻana i nā mea hana ho'āʻo kūikawā a me nā kaʻina hana ho'āʻo.
