Koho ʻia ke kaʻina hana wili no ka hoʻoheheʻe keleawe-aluminum

Me ka hoʻomohala wikiwiki ʻana o ka mana uila o koʻu ʻāina, ʻoi aku ka nui o ka hoʻohana ʻana i nā koi no nā ʻāpana copper-aluminum butt a ʻoi aku ka kiʻekiʻe o nā koi. ʻO nā kaʻina hana hoʻoheheʻe keleawe-aluminika maʻamau ma ka mākeke i kēia mau lā, ʻo ia ka: flash butt welding, rolling friction welding a me brazing. Na ka mea hoʻoponopono ma lalo nei e hoʻolauna i nā ʻano o kēia mau kaʻina no ʻoe.
Friction rolling welding i kēia manawa wale nō i ka welding bars, a welded bars hiki no hoi forged i loko o nā papa, akā, he mea maʻalahi ke kumu māwae o interlayers a me welds.
Hoʻohana nui ʻia ʻo Brazing, a ua hoʻohana nui ʻia no nā ʻāpana nui a me nā ʻano hui like ʻole keleawe-aluminum, akā aia kekahi mau mea e like me ka haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa, a me ka maikaʻi ʻole.
ʻO ke kuʻi ʻana o Flash Butt ke ala maikaʻi loa e wili ai i ke keleawe a me ka alumini. Loaʻa nā koi kiʻekiʻe o ka hoʻoheheʻe ʻana o Flash butt ma ka pā mana, a aia nō ka pohō. Eia naʻe, ʻaʻohe pores a me ka lepo o ka mea hana weld i ka weld seam a ʻoi aku ka kiʻekiʻe o ka ikaika o ka weld seam. Hiki ke ʻike ʻia ua ʻike ʻia kona mau hemahema, akā ua uhi ʻia kona mau mea maikaʻi i kona mau hemahema.
ʻO ke kaʻina hana welding butt welding copper-aluminum he mea paʻakikī, a he ʻokoʻa nā ʻāpana helu a hoʻopaʻa paʻa kekahi i kekahi, e pili ana kēlā me kēia i kona ʻano kuʻi. I kēia manawa, ʻaʻohe ala ʻike maikaʻi no ka maikaʻi o ke kuʻi keleawe-aluminika, a ʻo ka hapa nui o lākou e hoʻokō i ka ʻike luku e hōʻoia i kona ikaika (hiki i ka ikaika o nā mea alumini), i hiki ke hana pono i ka mana mana.
ʻO nā koi no ka hoʻoheheʻe ʻana i nā mea o ke keleawe-aluminum butt welding machine
1. Pono nā mea pono o ka mīkini wiliwili uila;
ʻAʻole pono ka haʻahaʻa o nā mea hoʻohana welding ma mua o ka maʻamau
2. E hoʻololi i nā pono ili o ka mīkini hoʻoheheʻe ʻōpuʻu uila:
ʻAʻole pono e loaʻa nā ʻili aila a me nā mea ʻē aʻe e pili ana i ka conductivity i ka wā e wili ai ma ka ʻili o nā ʻāpana, a ʻaʻohe pena ma ka ʻili hope wili a me nā ʻaoʻao ʻelua.
3. E hoʻololi i ka mīkini wiliwili uila uila nā mea pono e hoʻomākaukau mua ai:
Ke kiʻekiʻe loa ka ikaika o ka mea, pono e hoʻopili mua ʻia e hōʻoia i ka paʻakikī haʻahaʻa a me ka plasticity kiʻekiʻe o ka weldment, kahi e kūpono ai i ka extrusion o ka wai metala slag i ka wā o ka huhū.
4. E hoʻololi i ka nui o ka mīkini hoʻoheheʻe uila;
Ke koho ʻana i ka mānoanoa o ka mea hana welding e like me ka nui weldable o ka mīkini welding, koho i kahi waiwai maikaʻi ʻole no ke keleawe a me kahi waiwai kūpono no ka alumini (maʻamau 0.3 ~ 0.4). ʻAʻole pono ka ʻokoʻa mānoanoa ma waena o ke keleawe a me ka alumini ma mua o kēia kumukūʻai, inā ʻaʻole ia e hoʻokau i ka lawa ʻole a i ʻole ke kahe nui ʻana, e hoʻopilikia nui i ka maikaʻi o ka welding.
5. Nā koi no ka ʻāpana mea o ka mīkini hoʻoheheʻe ʻāwīwī:
Pono e palahalaha ka maka hope o ka weld, a ʻaʻole nui loa ka ʻoki ʻana, e hoʻoulu ʻia ka wela ma nā ʻaoʻao ʻelua o ka weld a hoʻoulu i ka weld ʻole.
6. ʻO ka nui o ka nui o ka mīkini wiliwili uila uila:
Ke hoʻopau ʻia ka weldment, pono e hoʻohui ʻia ka nui o ka puhi ʻana a me ka huhū i ke kiʻi e like me ke kaʻina hana kuʻi.
