Flangeulu wikiwiki ka ʻenehana hana ʻino.Pākaʻa flangeloaʻa nā waiwai kino a me nā mea kemika e like me ka oxidation ikaika, wahi heheʻe haʻahaʻa, ka hoʻokō wela wikiwiki, ka hoʻonui laina laina nui a me ka wela latent nui o ka heheʻe. No laila, pinepine kekahi mau pilikia i ke koho ʻana i ka welding.

I ka wā wili, hiki ke hoʻololi koke ʻia ka nui o ka wela i loko o ka metala kumu. No laila, i ka wā e kuʻi ai i nā alumini alumini a me nā alumini, hoʻopau ʻia ka ikehu ʻaʻole wale i loko o ka loko metala hoʻoheheʻe ʻia, akā ma nā wahi ʻē aʻe o ka metala. ʻOi aku ka nui o kēia hoʻohana ikehu pono ʻole ma mua o ke kila. I mea e loaʻa ai nā hui kuʻi kiʻekiʻe kiʻekiʻe, pono e hoʻohana ʻia ka ikehu a me ka mana kiʻekiʻe e like me ka hiki, a i kekahi manawa hiki ke hoʻohana ʻia ka preheating a me nā hana ʻenehana ʻē aʻe.
Ma mua o ka wiliwili ʻana, ʻo kaʻaʻohe pāe hoʻomaʻemaʻe loa ʻia e ke kemika a i ʻole ka mīkini e wehe i ke kiʻi ʻoniʻoni ma luna o kona ʻili. Ma GTAW, ho'opau 'ia ke ki'i oxide e ka "ho'oma'ema'e cathode" me ka lako mana AC. No ka hoʻoheheʻe kinoea, pono e hoʻohana i kahi flux e wehe i ke kiʻi oxide. I ka wā e wili ai i nā papa mānoanoa, hiki ke hoʻonui ʻia ka wela welding, a i ʻole ke hoʻohana ʻana i ka wili MIG nui. I ka hihia o ka pili dc, ʻaʻohe pono e hoʻomaʻemaʻe i ka cathode.
He maʻalahi ka hana ʻana i ka lua shrinkage, shrinkage porosity, thermal crack a me ke kaumaha kūloko kiʻekiʻe i ka wā paʻa o ka wai hoʻoheheʻe. Hiki ke lawe ʻia nā hana e hoʻoponopono ai i ka haku mele ʻana o ka uea a me ke kaʻina hana e pale ai i ka hiki ʻana mai o nā māwae wela i ka hana ʻana o ka flange blank. Ma waho aʻe o ka flange blank, hiki ke hoʻohana ʻia ka uea kuʻi flange blank no ka weld flange blank ma lalo o ke ʻano o ka pale ʻana i ka corrosion.
I ka wā o ka paʻa ʻana a me ka hoʻomaloʻo wikiwiki ʻana o ka loko i hoʻoheheʻe ʻia, ua lohi loa ka hydrogen a ua maʻalahi nā lua hydrogen. ʻO ka wai i loko o ka lewa arc, nā mea hoʻoheheʻe o ka flange blank a me ka wai i hoʻopili ʻia e ka film oxide ma ka ʻili metala kumu, ʻo ia nā kumu nui o ka hydrogen i ka welding o ka flange blank. No laila, pono e mālama pono ʻia ke kumu o ka hydrogen e pale ai i ka hoʻokumu ʻana o nā pores.

Flangehakahakakaʻina forgingʻO ka mea maʻamau e pili ana i kēia mau kaʻina hana, ʻo ia hoʻi, e koho i kahi billet maikaʻi no ka blanking, hoʻomehana, hoʻokumu a me ka hoʻomaha ʻana ma hope.ke kalaiwa ana. Hoʻokomo ʻia nā ʻenehana forging me ka forging manuahi, die forging a me die forging. I ke kaʻina hana, pono e koho ʻia nā ʻano forging like ʻole e like me ka maikaʻi o nā forgings a me ka helu o nā pūʻulu hana.
