1. ʻO ka ikaika hua a me ka elongation o ka pā keleawe he inversely proportional, ʻo ka paʻakikī o ka pā keleawe i hana ʻia e piʻi kiʻekiʻe loa, akā hiki ke hoʻemi ʻia e ka mālama wela.
2. ʻAʻole i kaupalena ʻia ka pā keleawe e ka mahana hana, ʻaʻole palupalu i ka haʻahaʻa haʻahaʻa, a hiki ke welded me ka puhi ʻana o ka oxygen a me nā ʻano hana hoʻoheheʻe wela ʻē aʻe ke kiʻekiʻe ka helu heheʻe.
3. Ma waena o nā mea metala a pau no ke kūkulu ʻana, ʻoi aku ka maikaʻi o ka elongation o ke keleawe a loaʻa iā ia nā pōmaikaʻi nui i ka hoʻololi ʻana i ke ʻano hoʻohālike.
4. He maikaʻi ka hoʻoponopono ʻana o ka pā keleawe a me ka ikaika, kūpono no nā kaʻina like ʻole a me nā ʻōnaehana e like me ka ʻōnaehana paʻa paʻa, ʻōnaehana paʻi kuʻekuʻe, etc.
● Liʻiliʻi ka wela i kūkulu ʻia
● ʻOi aku ka maikaʻi o ka ʻili
● ʻOi aku ka lōʻihi o ke ola paahana
● Hoʻonui i ka hana lua hohonu
● maikaʻi weld-hiki
●He kūpono no nā cores mold, cavities, a me nā mea hoʻokomo
