ʻO ka alumini maʻemaʻe he metala palupalu a maikaʻi hoʻi. No ka nui o nā hale, haʻahaʻa kona ikaika. No ka hoʻonui i ka ikaika o ka alumini, pono e hoʻohui i nā mea hoʻohui. Hoʻohana ʻia ke keleawe, silika, manganese, magnesium, a me ka zinc ma ke ʻano he mea nui e pāʻani i kahi hopena hoʻoikaika paʻa. Ua hoʻohana nui ʻia ka alumini a me ka alumini i nā ʻoihana he nui.
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 ka haʻahaʻa-carbon kila. 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.
1． Aluminum alloy GMAW welding
Ua komo mālie ʻo Gmaw welding i ko mākou ola. Hoʻohana pinepine ʻia ka pilina hoʻohuli DC i ka wā wili, a hiki ke hoʻohana pū ʻia ka wili pulse. Ke hoʻohālikelike ʻia me ka welding TIG, loaʻa i ka welding GMAW nā pono aʻe:
1. Aneane ʻaʻohe wela oxidative i ka wā o ke kaʻina hana kuʻi, a ʻoi aku ka maʻalahi o ka hana.
2. Kiʻekiʻe o ka hana hana.
3. Mai hāpai i nā pou tungsten, ke kumu kūʻai haʻahaʻa.
I ka wā e wili ai ma GMAW, e hoʻolohe i kēia mau mea:
1. Pono ʻoe e hoʻohana i kahi paiki siliki ma muli o ka plastic, a ʻaʻole hiki ke hoʻohana ʻia ke kaula kila.
2. He palupalu ka uea kuʻi alumini a ʻilihune ka lawe ʻana i ka uea. Pono ʻoe e koho i kahi huila hāʻawi uea ʻano U-shaped.
3. E hoʻohana i ka waha conductive anawaena kūpono.
4. Mai kaʻana like i nā ʻāpana me ka wili kila e pale i ka haumia.
Hoʻohana ʻo GMA-A5356 i ka hopena ma ka pūnaewele o kahi mea kūʻai
Hāʻawi kēia ʻikepili me nā mea hoʻohana e hoʻomaka ana a kokoke paha e welded, e ʻae iā mākou e holomua ma ke ala o ka wili alumini alumini.
ʻO nā huahana lako maʻamau o kā mākou hui penei:
