ʻO ke kuʻekuʻe wela wela mai ka hoʻopau ʻana i ka wili kila wela hope loa ma o ka hoʻoheheʻe ʻana i ka laminar a hiki i ka mahana i hoʻonohonoho ʻia, ʻo ia ka winder coil, ke kila kila ma hope o ka hoʻoluʻu ʻana, e like me nā pono like ʻole o nā mea hoʻohana, me nā laina hoʻopau ʻokoʻa (flat. , hoʻopololei, ʻoki ʻoki a i ʻole ka lōʻihi, ka nānā ʻana, ke kaupaona ʻana, ka hōʻailona a me ka logo, a me nā mea ʻē aʻe) a lilo i pā kila, ʻōwili pālahalaha a me nā huahana ʻokiʻoki lōʻihi.No ka mea, he ikaika kiʻekiʻe ka ikaika o nā huahana kila i ʻōwili ʻia, ka paʻakikī maikaʻi, ka hana maʻalahi a me ka weldability maikaʻi a me nā waiwai maikaʻi ʻē aʻe, hoʻohana nui ʻia ia i ka hana moku, kaʻa, alahaka, kūkulu, mīkini, moku kaomi a me nā ʻoihana hana ʻē aʻe.

ʻO ke kila kalapona kekahi ʻano kila maʻamau i hui pū ʻia me ka hao a me ke kalapona.He ʻoi aku ka nui o ke kalapona, wahi heheʻe haʻahaʻa a ʻoi aku ka lōʻihi e hoʻohālikelike ʻia me ke kila kila.
ʻO ke kila carbon ka mea i hoʻohana nui ʻia i ka ʻenekinia a me nā mea kūkulu hale no nā noi ʻoihana ma ke ʻano nui, me nā hale kai, nā mea kanu mana, ka lawe ʻana, ka hana kemika a me ka hana ʻaila a me ka hoʻomaʻemaʻe.
Δ Hoʻopili ʻia ka mea i ʻōwili ʻia i loko o ka umu hoʻoheheʻe anuanu a ma hope o ka pickling i loko o ka waikawa.
Δ Ua wili ʻia nā ʻōwili wili a pau ma ka mīkini wili pololei me ka chamfering kūpono ma hope o ka hana mua.
Δ Hoʻopiʻi ʻia nā pepa a pau i loko o nā pahu like ʻole a maloʻo ʻia nā pepa ma ka mīkini ʻōwili ma mua o ka hoʻouna ʻana.
Δ Hoʻopili hou ʻia kēia mau pepa a laila hoʻouna ʻia e hoʻopololei i ka mīkini no ka hoʻoponopono ʻana a me ka pickling i loko o ka waikawa a hoʻouna ʻia no ka hoʻopili ʻana e like me ka nui a me ka maikaʻi.
Hana ʻia ka nānā ʻana ma nā pae like ʻole.Ma ka ʻike ʻana i nā limahana e mālama pono ana i ke kaʻina holoʻokoʻa holoʻokoʻa ma o ka ʻōwili ʻana, annealing, pickling, mālama ʻana i ka ʻōpala etc.
