Nā ʻano wili like ʻole: ʻaʻole hiki ke nānā ʻia nā welds palahalaha e ka lekiō, akā hiki ke nānā ʻia nā welds butt e ka radioography. Hoʻohana ʻia ʻo Fillet welding no ka wili palahalahanā leheleheanā lehelehe, oiai ua hoohanaia ka wiliwili apo nowiliwili puʻupuʻua me na paipu. ʻO ka weld paʻa he ʻelua weld fillet a me ka weld butt he weld butt.
ʻO ka ʻokoʻa ma waena o ka maʻalahiwelded flangeme ka ai aflange wiliwili ʻiaʻaʻole ʻāʻī he nui akunā lepa i wiliwili ʻiame ka ai mamuanā leheleheme ka ʻāʻī ʻole o ka ʻāʻī ma ka ʻāpana welded o ka paipu. Apalahalaha welded flangeme ka ai ole he aflange palahalaha, a ʻo ka luna me ka ʻole o ka flange he ʻāpana palahalaha. ʻO ka weld ma waena o ka ʻāʻī kuʻi ʻana o ka ʻāʻī a me ka hui hoʻokipa ʻana he weld B.

ʻO ka weld ma waena o nāʻāʻī palahalahaa ʻo ka hui e loaʻa ana i ka hui C, a ʻokoʻa ka hoʻāʻo non-destructive ma hope o ke kuʻi ʻana. E hoʻohālikelike i ka ʻokoʻa ma waenawiliwili palahalahaa me ka wiliwili puʻupuʻu. ʻOkoʻa ka mea maka: ua hana ʻia ka mea maka o ka ʻāʻī palahalaha welding flange mai ka pā kila maʻamau, a hiki i kona mānoanoa ke hoʻokō i nā koi. ʻO nā mea maka o ka butt welding flange me ka ʻāʻī e hana nui ʻia mai nā ʻāpana kila forged.
ʻOkoʻa ke kaomi nominal: ʻo ke kaomi nominal o ka ʻāʻī kuʻi ʻana i ka ʻāʻī he 0.6 -- 4.0MPa, ʻoiai ʻo ke kaomi nominal o ka ʻāʻī kuʻi ʻana o ka ʻāʻī he 1--25MPa. ʻIke loa, ʻoi aku ka haʻahaʻa o ka papa kaomi noi o ka flange welded neck flat. Nā ʻano hoʻohui like ʻole: ʻO ka ʻokoʻa ʻokoʻa ma waena o nā flanges kuʻekuʻe ʻāʻī ʻāʻī a me nā flanges kuʻi ʻāʻī ʻāʻī ʻo ia ka pili ʻokoʻa o ka mea hoʻokipa a me ka flange. ʻO nā ʻāʻī i hoʻopaʻa ʻia i ka ʻāʻī, ʻo ia ka mea maʻamau a me nā ʻaoʻao ʻaoʻao o ka ʻāʻī, ʻoiai ʻo nā flanges i hoʻopaʻa ʻia ma ka ʻāʻī ʻo ia nā ʻāpana a me ka pahu pahu.
