He aha ke alo o Hard?

ʻO ke alo paʻakikī, i kapa ʻia hoʻi ka paʻakikī i luna, he kaʻina hana metala no ka hoʻopili ʻana i nā metala ʻoi aku ka paʻakikī, nā ʻāpana wela kiʻekiʻe, nā seramika a me nā uhi ʻē aʻe i nā metala kumu e hoʻomaikaʻi ai i ka lole maʻamau, ka ʻinoʻino, ka paʻakikī a me nā ʻano ʻano kino a me nā kemika o ka metala kumu.

a me nā mea uhi ʻē aʻe i nā metala kumu e hoʻomaikaʻi ai i ka ʻaʻahu maʻamau, ka ʻinoʻino, ka paʻakikī a me nā ʻano kino a me nā kemika ʻē aʻe o ka metala kumu.

I ka manawa hea ke alo paʻakikī?

Hoʻohana mau ʻia ke alo paʻakikī i nā pōʻai ola āpau o kahi ʻāpana i hana ʻia a i ʻole ka mīkini. Ma keʻano laulā, hoʻohana ʻia ke alo paʻakikī.

Ma nā ʻāpana hou e hoʻonui i ka pale ʻaʻahu.

Ma ka hoʻohana ʻana, hoʻohana ʻia i lalo i ka hoʻomanawanui, hoʻolōʻihi i ke ola hana.

Ma nā lako hana e hoʻolōʻihi i ke ola o nā ʻāpana i hana ʻia ma ke ʻano o ka papahana mālama.

Pehea e hoʻohana ʻia ai ke alo paʻakikī?

Nui nā ʻano hana e hoʻohana ai i ke alo paʻakikī. Hoʻohana ʻia kēlā mau ʻano i nā noi like ʻole. No laila, ʻaʻohe mea i ʻoi aku ka maikaʻi ma mua o nā mea ʻē aʻe, akā ua ʻōlelo ʻia ke ʻano ma muli o ke kumu i manaʻo ʻia o ke alo paʻakikī. ʻO kekahi o nā ʻano hana welding maʻamau:

1. Palekana Metal Arc Welding (SMAW)

2. Hoʻoheheʻe ʻia ʻo Gas Metal Arc (GMAW)

3. Hoʻoheheʻe Oxyfuel (OFW)

4. Welding Arc Submerged (SAW)

5. Uila Uila (ESW)

6. Hoʻoheheʻe ʻia ʻo Plasma Transfered Arc Welding (PTAW)

7. Hoʻopuʻi wela

8. Nā pūhui polymer anuanu

9. Hoʻopili Laser

Ua hoʻokomo ʻia ke alo paʻakikī i nā papahana kūʻai a mālama ʻia no nā ʻoihana like ʻole, akā ʻaʻole i kaupalena ʻia, Steel, Cement, Mining, Petrochemical, Power, Sugarcane and Food, Process Chemical, a me nā mea hana maʻamau.

ʻO nā lako a me nā kumukūʻai o ke alo paʻakikī

ʻO ka ʻenehana paʻakikī no kahi hana e pili ana i ka geometry o ka ʻāpana a me ke kumukūʻai pili o ke ʻano paʻakikī. Hiki ke ʻokoʻa ke kumukūʻai me ka helu deposition o ka mea.

Hiki ke hōʻuluʻulu ʻia kēia mau kumukūʻai like ʻole:

•ʻO ka wiliwili arc-cored arc (FCAW) 8 a 25 lb/hr

•Kuʻi ʻia ʻana o nā mea hao metala pale pale (SMAW) 3 a 5 lb/hr

•ʻO ka wiliwili ʻana o Gas Metal Arc (GMAW), me ka hoʻoheheʻe ʻia ʻana o ke kinoea a me ka hāmama arc 5 a 12 lb/hr.

•Oxyfuel Welding (OFW) 5 a 10 lb/hr

Inā makemake ʻoe e aʻo hou aʻe e pili ana i nā ala paʻakikī, nā noi, a i ʻole e ʻimi ana i kahi kūkākūkā, e kelepona iā zzbetter carbide.
