Pehea e ʻoi aku ka maikaʻi o ka welded alumini alloy

ʻOi aku ka paʻakikī o ka hoʻopili ʻana o ka alumini a me ka alumini ma mua o ke kila haʻahaʻa-carbon.ʻOkoʻa kona mau hiʻohiʻona wiliwili me ke kila haʻahaʻa-carbon.ʻO ka hana kūikawā penei:
1. Soferality o welded hoʻohui mechanical hana, emi corrosion kū'ē.
2. He ikaika loa ka hana kemika, a ua maʻalahi ka ili.
3. ikaika thermal conductivity, a he mea maʻalahi ke kumu insoluble phenomena i ka wā welding.
4. ʻO nā hemahema e like me nā pores, nā māwae, nā ʻaoʻao nahu, ka slag a me ka hana weld.
5. ʻO ka helu hoʻonui laina nui (e pili ana i 2 mau manawa o ke kila haʻahaʻa haʻahaʻa), hiki ke hoʻololi i ka warp a me ka deformation i ka wā wili.
6. He nui ka thermal conductivity (e pili ana i 5 manawa ka haʻahaʻa -carbon kila).Ma ka wikiwiki hoʻohui like, ʻo ka hoʻokomo wela he 2 a 4 mau manawa nui ma mua o ke kila welding.

Hoʻopili ʻia ke alumini alumini me TIG a i ʻole GMAW.

1． Aluminum alloy tig welding
Inā pono ʻoe e kiʻi i ka welding kiʻekiʻe loa, ʻo Tig welding ka mea koho mua.ʻO ke ala kaʻina hana kūpono e hoʻololi i ka welding TIG a me ka AC pulse TIG welding.Nui nā pono:

1. I ka wā e wili ai, hiki ke wehe ʻia nā hiʻohiʻona cathode atomization iā ia iho.
2. ʻAʻole i kaupalena ʻia ke ʻano pili, maʻemaʻe ka ʻili a maikaʻi no ka hana ʻana.
3. ʻO ka'āpana hoʻoheheʻe o ka ea e hoʻomaha i nā hono e hoʻomaha a hoʻonui i ka hui a me ka hana.
No laila, kūpono loa kēia kaʻina hana i ka ʻoihana aerospace kiʻekiʻe a koʻikoʻi.ʻOiaʻiʻo, ua maopopo loa kona mau hemahema.He haʻahaʻa ka maikaʻi o ka welding, a ʻaʻole kūpono ia no ka hana ʻana o ka nui-scale high-efficiency.
