Haʻahaʻa-alloy steels Manual electrode E7018-B2L metala Jointing makings
ʻO ka pauka hao haʻahaʻa hydrogen potassium ʻano koʻokoʻo kuʻi lima, paʻa arc
ʻO ka liʻiliʻi liʻiliʻi, hoʻoheheʻe maikaʻi, maʻalahi e wehe i ka hana X-Ray slag
Hiki ke mālama ʻia nā waiwai mechanical paʻa, ʻoi aku ka ikaika ma lalo o nā kūlana mālama wela
