Nā hemahema Weld:He koʻikoʻi ka weld defects, hoʻohana ʻia ke ʻano hana hana wili mīkini lima e uku ai, e hopena i nā kaha wili, ka hopena i ka ʻili ʻole, pili i ka helehelena.
Ka ʻili like ʻole:ʻO ka pickling a me ka passivation wale nō o ka weld e hana i ka ʻili ʻole a pili i ka helehelena.
He paʻakikī ke wehe i nā ʻōpala:holoʻokoʻa pickling passivation, ʻaʻole hiki ke hana ʻia i ke kaʻina o nā ʻano ʻōpala āpau i wehe ʻia, a ʻaʻole hiki ke wehe ʻia ma muli o nā ʻōpala, nā kuʻi ʻana a me ka adhesion ma luna o ka ʻili o ke kila kila kila, nā ʻōpala a me nā mea haumia ʻē aʻe, ka hopena i ke alo o ka corrosive. media ma lalo o ke kūlana o ka ʻino kemika a i ʻole ka ʻino electrochemical a me ka ʻōpala.
ʻO ka poli ʻole a me ka passivation:Hoʻokō ʻia ka mālama passivation pickling ma hope o ka polishing manual a me ka polishing. He paʻakikī ka loaʻa ʻana o ka hopena lapaʻau like ʻole a paʻa no nā forgings nui, a ʻaʻole hiki ke loaʻa kahi ʻano like ʻole. A ʻoi aku ka kiʻekiʻe o ke kumukūʻai o nā hola hana, nā mea kōkua.

Ua kaupalena ʻia ka hiki ke koho ʻana:ʻAʻole ʻo pickling passivation paste, no ka ʻoki ʻana i ka plasma, ka ʻoki ahi a me ka ʻeleʻele ʻeleʻele, paʻakikī ke wehe.
ʻOi aku ka koʻikoʻi o nā ʻōpala i hana ʻia e nā kumu kanaka:i ke kaʻina o ka hāpai ʻana, ka lawe ʻana a me ka hoʻoponopono ʻana, ʻoi aku ka koʻikoʻi o nā ʻōpala i hana ʻia e ke kīkēkē, kauo, hāmare a me nā mea ʻē aʻe o ke kanaka, ʻoi aku ka paʻakikī o ka mālama ʻana i ka ʻili, a ʻo ia ke kumu nui o ka corrosion ma hope o ka mālama ʻana.
Nā mea lako: ma ka ʻaoʻao, ke kuʻi ʻana o ka pā, ke kaʻina hana kulou, i hana ʻia e nā ʻōpala a me nā creases ke kumu nui o ka corrosion ma hope o ka mālama ʻana.
Nā kumu ʻē aʻe:kuhiliʻolehao haoi ke kūʻai ʻana, ke kaʻina hana mālama, ma muli o ka hāpai ʻana, ʻoi aku ka koʻikoʻi o ke kaʻina lawe ʻana o ka puʻu a me nā ʻōpala, ʻo ia kekahi o nā kumu o ka corrosion.
