Welding: E ​​hoʻopaʻa ʻia nā kuʻina, e hoʻopili piha ʻia.

E hana ʻia ka welding e like me nā kaʻina hana i kuhikuhi ʻia ma ka Pauku IX o ka ASME Boiler and Pressure Vessel Code.

E hana ʻia nā welds me ka lima a i ʻole ma ke kaʻina hana uila e pili ana i ka waiho ʻana o ka metala filler.

Lapaau Wela no na Papa like ole

ʻO nā papa ʻē aʻe ma mua o 10, 11, 12, a me 13 e mālama ʻia i ka wela i loko o kahi umu i hoʻomalu ʻia i ± 25 °F[± 15°C].

Nā papa 20, 21, 22, a me 23

E hoʻomaʻamaʻa like ʻia i loko o ka pae wela o ka mālama ʻana i ka wela ma hope o ka weld i hōʻike ʻia ma ka Papa 2 no ka liʻiliʻi o 1 h/in.[0.4 h/cm] o ka mānoanoa a i ʻole no 1 hola, ʻo ia ka mea i ʻoi aku ka nui.

Nā papa 30, 31, 32, a me 33

E hoʻomaʻamaʻa like ʻia a hiki i kahi wela ma ke ʻano austenitizing a ʻaʻole i ʻoi aku ma mua o ka wela maʻamau i hōʻike ʻia ma ka Papa 2 a ma hope iho e hoʻomaha ʻia i ka ea ma ka wela lumi.

Nā papa 40, 41, 42, a me 43

E hoʻomaʻamaʻa ʻia ka paipu.

E hoʻomaʻamaʻa hou ʻia ka paipu i ka wela wela i hōʻike ʻia ma ka Papa 2 ma ke ʻano he haʻahaʻa loa a mālama ʻia ma kahi mahana no ka liʻiliʻi o 0.5 h/in.[0.2 h/cm] o ka mānoanoa a i ʻole 0.5 h, ʻo ia ka mea i ʻoi aku ka nui, a me ka ea- hooluolu.
