Nā hemahema maʻamau o ka paipu kila welded:

(1) kila papa
ʻO ke ʻano o ka paipu kila pāpaʻi ʻia, ua māhele ʻia ka ʻāpana keʻa i ʻelua papahele, ʻike ʻia ka ʻili kila e hōʻike ana i nā māwae hierarchical vertical.ʻO kekahi mau mea hōʻike i loko a i waho o ka ʻili kila i hoʻihoʻi ʻia a i hoʻokiʻekiʻe ʻia ma ka ʻāina, ua hoʻokiʻekiʻe koke ʻia ka hoʻoheheʻe ʻana, nā niho a i ʻole ke kaua ʻana i loko a i waho o ka weld.
(2) ʻili ʻili
ʻO ka ʻili paʻa paipu e pili ana i ka ʻili o loko a me waho o ka ʻili kila nui.
(3) puka
ʻO ka paipu ma loko o ka lua e pili ana i kahi lua paipu kila kūloko.
(4) welding welding
Welded kila paipu wehe 'o ia hoʻi ma o ka lōʻihi māwae ma kila welds a hapa hōʻike o.
(5) Kuʻi wili ʻūhā kūloko
ʻO ka paipu kila welded e pili ana i kahi ʻāpana o waho o ka paipu kila e hōʻike ana i kahi weld arc.
(6) Auwai wiliwili
ʻO ke awāwa hoʻoheheʻe paipu ʻo ia ka ʻili o waho o ka paipu kila e hana ʻia ma o ka weld awāwa lōʻihi.
(7) ka hāʻule ʻana o ka welding
ʻO ka hāʻule ʻana o ka paipu kila welo e pili ana i ka ʻili o waho o nā iwi weld metala e hōʻike ana ma o kahi ʻauwaha lōʻihi, kahi i ka ʻili o nā kihi convex pili.
(8) ka wehe ʻana o nā hui paipu
Steel paipu ami dislocation pili i ke kila paipu weld, i ka hanana o staggered i luna a me lalo.
