Hana ʻia ka wili ʻōwili wela me ka papa (ʻoi aku ka nui o ka hoʻolei ʻana i ka billet) ma ke ʻano he mea maka, i hoʻomehana ʻia a hana ʻia e ka wili wili a me ka wili hoʻopau.ʻO ka wili ʻōwili wela ʻO ka ʻili kila wela mai ka wili hoʻopau hope loa e hoʻoluʻu ʻia i ka wela i hoʻonohonoho ʻia e ke kahe laminar, a ʻolokaʻi ʻia ka wili kila e ka coiler.Hoʻopiliʻia ka'ōwili kila kila e nā laina hoʻopau likeʻole (leveling, straightening, cross-cutting or longitudinal cutting, inspection, weight, packaging and marking, etc.) e like me nā pono likeʻole o nā mea hoʻohana.
I mea e maʻalahi ai, ua wela kahi ʻāpana billet (ʻo ia hoʻi, ka ʻulaʻula a wela o ke kila i puhi ʻia ma ka TV) a laila ʻōwili ʻia i nā manawa he nui, a laila ʻoki ʻia a hoʻopololei ʻia i loko o kahi pā kila, i kapa ʻia ʻo ka ʻōwili wela. .
Ma muli o kona ikaika kiʻekiʻe, paʻakikī maikaʻi, hana maʻalahi a me ka weldability maikaʻi, hoʻohana nui ʻia nā huahana pā kila wela i nā moku, nā kaʻa, nā alahaka, ke kūkulu ʻana, nā mīkini, nā moku kaomi a me nā ʻoihana hana ʻē aʻe.
Me ka oʻo o nā ʻenehana hoʻomalu hou e like me ka pololei o ka dimensional, ke ʻano a me ka maikaʻi o ka ʻili o ka ʻōwili wela a me ka hiki ʻana mai o nā huahana hou, ua hoʻohana nui ʻia nā huahana wela a me nā pā kila a ʻoi aku ka ikaika a me ka ikaika o ka hoʻokūkū ma ka mākeke.
