Eia kekahi, aia kekahi mau koi no ka microstructure, ka nui o ka palaoa, a me ka papa decarburization o ka paipu kila i hoʻopau ʻia.
Ho'āʻo Uʻi:
1. No ka mea kila o nā huahana, pono e hana ka mea hana i ka ho'āʻo tensile. No ka paipu welded electric, ma muli o ke koho a ka mea hana, hiki ke hana i ka ho'āʻo tensile ma ka pā kila i hana ʻia i ka paipu a i hana ʻia ma ka paipu kila. Hiki ke hoʻohana ʻia kahi hoʻokolohua i hana ʻia ma kahi huahana ma ke ʻano he hōʻike huahana.
2. E koho wale ia na paipu hoao.

5. Inā ʻaʻole i kūpono kekahi laʻana e hōʻike ana i kahi paipu i nā koi i ʻōlelo ʻia, hiki i ka mea hana ke lawe i kahi laʻana mai ka hopena like o ka paipu no ka hoʻāʻo hou ʻana a hiki i ka hoʻokō ʻana i nā koi. Eia naʻe, ʻaʻole pono e emi ka lōʻihi o ka paipu i hoʻopau ʻia ma hope o ka laʻana ma mua o 80% o ka lōʻihi kumu. Inā ʻaʻole kūpono kekahi laʻana o ka paipu e hōʻike ana i kahi pūʻulu o nā huahana i nā koi i kuhikuhi ʻia, hiki i ka mea hana ke lawe i ʻelua mau paipu hou mai ka pūʻulu o nā huahana a ʻoki i nā laʻana no ka hoʻāʻo hou ʻana. Inā kūpono nā hopena o kēia mau ho'āʻo hou i nā koi, ua kūpono ka pūʻulu o nā paipu koe wale nō ka paipu i koho mua ʻia e like me ka laʻana. Inā ʻaʻole i hoʻokō kekahi o nā laʻana hoʻāʻo hou i nā koi i kuhikuhi ʻia, hiki i ka mea hana ke hoʻāʻo i nā paipu i koe o ka pūʻulu pakahi.
