Nā mea kumu: ʻO nā pā uila electrolytic I-pae me ka mānoanoa o like a ʻoi aku paha ma mua o 0.8mm e hoʻohana ʻia.
ʻIlikai mea: Hoʻohana ʻia ka pauka palakiko kiʻekiʻe loa, a loaʻa iā ia nā mea like a me nā ʻāpana maikaʻi, ke kala like a me ka hoʻopili ikaika.
ʻO nā pono pono lako paʻa: hoʻohana ʻia nā loka kila kila i lawe ʻia mai me nā puʻupuʻu māmā i pīpī ʻia me PU.
Iecaianoaaiiuo kaʻina: mōlina a me ka welded nā mea hana → ka waikawa pickling a me ka wehe ʻana i ka popo → ka hoʻoliʻiliʻi māmā → ka holoi wai → ka holoi ʻana i ka alkali a me ka hoʻoneʻe ʻana i ka aila .
Hōʻike: ʻEkolu papa paʻi hoʻoneʻe me kahi lima hina.
Nānā hou: 1.0mm ka mānoanoa o ka papapa, he ʻehā anuenue ka wehe ʻana o ka papa, ʻo ka mānoanoa o ka pā kila o ka iwi ʻaoʻao e hoʻonui ana ʻo 1.0mm, a ua kī ʻia ka mokulele ʻaoʻao me nā auwai concave e hoʻomaikaʻi ai i ka halihali ukana. ʻO nā laka he ʻelua mau laka laka, a palekana a hilinaʻi ʻia, nani a kūpaʻa. Lawe ʻia ke kaʻina hana pulse holomua, a paʻa ka wahi kuʻihao a kiʻekiʻe ka pālahalaha.
