Kaʻina hana kuʻi lāʻau intro
Kapa ʻia ʻo SMAW (Shielded Metal Arc Welding) he wili lāʻau.ʻO ia kekahi o nā kaʻina hana welding kaulana loa i hoʻohana ʻia i kēia lā.ʻO kona kaulana ma muli o ka versatility o ke kaʻina hana a me ka maʻalahi a me ke kumukūʻai haʻahaʻa o nā mea hana a me ka hana.Hoʻohana mau ʻia ʻo SMAW me nā mea e like me ke kila māmā, ka hao hao, a me ke kila kila.
Pehea ka hana ʻana o ka wili lāʻau
ʻO ka wili lāʻau he kaʻina hana kuʻi lima lima.Pono ia i kahi electrode consumable i uhi ʻia i ka flux e hoʻomoe i ka weld, a hoʻohana ʻia ke ʻano uila no ka hana ʻana i kahi arc uila ma waena o ka electrode a me nā metala e wili pū ʻia.ʻO ke au uwila paha he kaha ʻokoʻa a i ʻole ke au pololei mai kahi lako mana kuʻi.
ʻOiai e waiho ʻia ana ka weld, hemo ka uhi ʻana o ka flux electrode.Hoʻopuka kēia i nā mahu e hāʻawi i kahi kinoea pale a me kahi papa o ka slag.Mālama ke kinoea a me ka slag i ka wai weld mai ka haumia o ka lewa.Hoʻohana pū ka flux e hoʻohui i nā scavengers, deoxidizers, a me nā mea hoʻohui i ka metala weld.
Nā Electrodes i uhi ʻia i ka Flux
Hiki iā ʻoe ke loaʻa nā electrodes i uhi ʻia i ka flux i nā ʻano anawaena a me nā lōʻihi.ʻO ka maʻamau, i ke koho ʻana i kahi electrode, makemake ʻoe e hoʻohālikelike i nā waiwai electrode i nā mea kumu.ʻO nā ʻano electrode i uhi ʻia i ka flux me ke keleawe, ke keleawe aluminika, ke kila māmā, ke kila kila, a me ka nickel.
Nā hoʻohana maʻamau o ka wili lāʻau
Kaulana nui ʻia ʻo SMAW ma ka honua holoʻokoʻa e hoʻomalu i nā kaʻina hana wili ʻē aʻe i ka ʻoihana hoʻoponopono a mālama.Ke hoʻomau nei ka hoʻohana nui ʻia i ka hana ʻenehana a me ke kūkulu ʻana i nā hale kila, ʻoiai ke ulu nei ka wiliwili flux-cored arc i kaulana i kēia mau wahi.
Nā ʻano ʻē aʻe o ka wili lāʻau
ʻO nā hiʻohiʻona ʻē aʻe o Shielded Metal Arc Welding penei:
- Hāʻawi ia i nā kūlana kūlana āpau
- ʻAʻole paʻakikī loa ia i ka makani a me nā kikoo
- ʻO ka maikaʻi a me ke ʻano o ka weld e like me ke akamai o ka mea hana
- Hiki iā ia ke hana i ʻehā ʻano hui welded: ʻo ka hui pū, hui pū, T-joint, a me ka weld fillet.
