ʻO ka hana nui omaikaʻi forgingsʻo ka nānā ʻana a me ka nānā ʻana i ka maikaʻi e ʻike i ka maikaʻi onā kalaiwa, kālailai i nā kumu ohana hewaa me nā hana pale, e kālailai i nā kumu ohana hewa, hoʻopuka i nā hana pale a me ka hoʻomaikaʻi maikaʻi, he ala nui ia e hoʻomaikaʻi ai a hōʻoia i ka maikaʻi o nā forgings. Mai nā hemahema forging hiki ke ʻike ʻia he nui nā mea e pili ana i ka maikaʻi forging, ʻoi aku ka nui o ka maikaʻi o nā mea maka he hopena koʻikoʻi, akā pili pū kekahi i ke kaʻina hana forging a me ke kaʻina hana wela. No laila, ʻo ka nānā ʻana a me ka noiʻi ʻana no ka hoʻopaʻa ʻana i nā pilikia maikaʻi, he hana akahele a paʻakikī.
ʻO ke kaʻina hana maʻamau o ka nānā ʻana i ka maikaʻi o nā forgings:
1. E noiʻi i ke kūlana kumu, me ka hoʻokolokolo ʻana i nā mea maka akaʻina forging. Pono ka mea mua e ʻike i ka maikaʻi o nā mea maka, a me ka ʻenehana hoʻoheheʻe a me ka hana ʻana o nā mea maka. Pono ka mea hope e noiʻi inā kūpono ke kaʻina hana forging a me ka hoʻokō maoli ʻana o ka hana forging.
2. E wehewehe i ka pilikia maikaʻi, ʻo ka mea nui e hoʻomaopopo i ke kumu, e ʻike i nā hemahema o ka hoʻopaʻa ʻana i nā ʻāpana a me nā hiʻohiʻona macro o nā hemahema, hoʻoholo mua ʻia e nā mea maka, a i ʻole ma ke kaʻina hana forging.

3. ʻO ka noiʻi hoʻokolohua a me ka nānā ʻana, ʻo ia ka pae nui e hoʻoholo ai i ke kumu o nā hemahema o ka forgings, ʻo ia hoʻi, ua hoʻohālikelike ʻia nā forgings hemahema a hoʻopaʻa ʻia e hoʻoholo i nā ʻano o nā hale macroscopic a me nā microscopic; Inā pono, pono ka ho'āʻo hoʻohālikelike o nā kaʻina kaʻina hana e aʻo a kālailai i nā kumu ohana hewa.
4. Nā hāʻina i manaʻo ʻia, ma muli o nā kumu maopopo ohana hewa, hui pū ʻia me ka hana hana, nā hana pale a me nā hoʻonā.
Nā ʻano hoʻāʻo omaikaʻi forgingsʻO ka nānā ʻana he: haʻahaʻa-mana microstructure ho'āʻo, metallographic microstructure ho'āʻo a me ka metala deformation a me kahe ana ho'āʻo. E like me ka mea i ʻōlelo ʻia ma luna, hiki i ka hoʻāʻo haʻahaʻa haʻahaʻa ke hōʻike i nā hemahema macro o ka forgings; He mea kōkua ka hōʻike microstructure metallographic i ke aʻo ʻana a me ka nānā ʻana i nā hiʻohiʻona microstructure a me ka hoʻokumu ʻana o nā hemahema. He koʻikoʻi koʻikoʻi ka hoʻāʻo ʻana o ke kahe deformation metala i ka nānā ʻana i ka māwae, ka pelu ʻana, ka hoʻokumu ʻana i ka palaoa coarse, ka hoʻohele streamline a pēlā aku. I forgings quality analysis, ua hui pinepine ia me ka luna ekolu. Me ka hoʻomohala wikiwiki ʻana o ka ʻenehana hou, ua hoʻohana ʻia kekahi mau ʻenehana hoʻāʻo holomua e like me ke ʻano hoʻāʻo non-destructive, microscope electron, etc. hoʻomohala kūpono.
