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. Ke koi ʻia nā hoʻāʻo he nui, e hōʻoia ke ʻano laʻana e hiki i nā laʻana i lawe ʻia ke hōʻike i ka hoʻomaka a me ka hopena o ka pōʻai wela (inā pili) a me nā ʻaoʻao ʻelua o ka paipu.

3. Hiki ke lawe 'ia ka la'ana paipu seamless ma kekahi kulana ma ke anapuni o ka paipu; e lawe ʻia ka laʻana paipu welded ma kahi o 90 ° i ka weld seam, a i ʻole ma ke koho o ka mea hana. Lawe ʻia nā laʻana ma kahi o ka hapahā o ka laula o ka lau.
4. ʻAʻohe mea ma mua a ma hope o ka hoʻokolohua, inā ʻike ʻia ka hoʻomākaukau ʻana i ka laʻana he hemahema a i ʻole ka nele o nā mea i pili ʻole i ke kumu o ka hoʻokolohua, hiki ke ʻoki ʻia ka hāpana a hoʻololi ʻia me kahi laʻana i hana ʻia mai ka paipu like.
5. Inā ʻaʻole i kūpono ka hoʻāʻo tensile e hōʻike ana i kahi pūʻulu o nā huahana i nā koi, hiki i ka mea hana ke lawe i 3 mau paipu hou mai ka pūʻulu like o nā paipu no ka nānā hou ʻana.
Inā kūpono nā ho'āʻo hou a pau o nā laʻana i nā koi, ua kūpono ka pūʻulu o nā paipu koe wale nō ka paipu kūpono ʻole i hoʻohālikelike mua ʻia.
Inā ʻoi aku ma mua o hoʻokahi laʻana i hōʻike mua ʻia a i ʻole hoʻokahi a ʻoi aku paha nā laʻana no ka hoʻāʻo hou ʻana ʻaʻole i kūpono i nā koi i ʻōlelo ʻia, hiki i ka mea hana ke nānā i ka pūʻulu o nā paipu i kēlā me kēia.

Ho'āʻo palahalaha:
1. 'O ka mea ho'ā'o he apo ho'ā'o a 'oki hope 'ole ma lalo o 63.5mm (2-1 / 2in).
2. Hiki ke ʻoki ʻia nā hiʻohiʻona ma mua o ka hoʻomaʻamaʻa ʻana i ka wela, akā ma lalo o ka mālama wela e like me ka paipu i hōʻike ʻia. Inā hoʻohana ʻia kahi hoʻāʻo pūʻulu, e hana ʻia nā ana e ʻike ai i ka pilina ma waena o ka hāpana a me ka paipu laʻana. Pono e ʻoki ʻia kēlā me kēia umu i kēlā me kēia pūʻulu.
3. E hoʻopalahalaha ʻia ka mea hoʻohālike ma waena o nā papa ʻelua. I kēlā me kēia pūʻulu o nā hōʻike hoʻāʻo palahalaha, ua pālahalaha ʻia kahi weld ma 90 ° a ʻo kekahi i pālahalaha ʻia ma 0 °.

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. Ma ke koho a ka mea hana, hiki ke hoʻomaʻamaʻa hou ʻia kēlā me kēia pūʻulu o nā paipu a hoʻāʻo hou ʻia e like me kahi pūʻulu o nā paipu hou.
