ʻO ke kaʻina hana okiʻekiʻe-frequency welded paipupili nui i ke ʻano o nā huahana. Pono nā kaʻina hana maimea makai nā huahana i hoʻopau ʻia. Pono ka hoʻopau ʻana o kēia mau kaʻina hana i nā ʻano mīkini like ʻole a me ka welding, ka mana uila a me nā mea ʻike. Hoʻonohonoho pono ʻia kēia mau lako a me nā mea hana e like me nā koi kaʻina like ʻole, Typical kaʻina okiʻekiʻe-frequency welded paipu: uncoiling - hoʻopaneʻe ʻāʻī - ʻāhi poʻo a me ka huelo - welding butt - hoʻopaʻa ʻana i ka looper - hoʻokumu ʻia - Welding - wehe ʻana i ka burr - sizing - ʻike hewa - ʻoki lele - nānā mua - hoʻopololei ʻana i ka paipu kila - ka hoʻoheheʻe ʻana i ka pauku - hydrostatic test - ʻike hewa - ka paʻi ʻana a me ka uhi ʻana - nā huahana i hoʻopau ʻia.
