Hiki i nā metala like ʻole (e like me ke kila a me ka alumini) ke welded? ʻO wai ka mīkini welding kūpono?

I ka hana ʻoihana a me ka hoʻoponopono ʻana i kēlā me kēia lā, he mea maʻamau ka pono e hui pū i nā ʻano metala like ʻole, e like me ke kila a me ka alumini. He nui ka poʻe e noʻonoʻo nei: Hiki i ke kila a me ke alumini, nā mea ʻokoʻa loa, ke welded pū? A inā hiki iā lākou, he aha ke ʻano o ka mīkini kuʻi e kūpono? I kēia lā, e wehewehe au i kēia mau pilikia ma ka ʻōlelo maʻalahi e kōkua i ka poʻe a pau e hoʻomaopopo i ka paʻakikī o ka wiliwili ʻana i nā metala like ʻole.

 I. Hiki i ke kila a me ka alumini ke wili? ʻAe ka pane, akā paʻakikī

ʻO ka mea mua, e ʻae mai iaʻu e hōʻoiaʻiʻo iā ʻoe: Hiki ke wili pū ʻia ke kila a me ka alumini. Eia nō naʻe, ke hoʻohālikelike ʻia i ka wili ʻana i ke ʻano metala like, ʻoi aku ka kiʻekiʻe o ka paʻakikī, ma muli o kēia mau ʻaoʻao ʻelua:

Ma kekahi ʻaoʻao, ʻokoʻa nā ʻano like ʻole o ke kila a me ka alumini. He wahi hehee ko ke kila ma kahi o 1,500 ℃, oiai he alumini ka hehee ma 660 ℃ wale nō. He mea paʻakikī kēia i ka hoʻomalu ʻana i ka wela i ka wā wili - inā haʻahaʻa loa ka mahana, ʻaʻole hehee ke kila; inā kiʻekiʻe loa, e puhi maʻalahi ka alumini a i ʻole ke ʻano. Eia kekahi, ʻokoʻa ka wikiwiki o ka lawe ʻana i ka wela. Lawe ʻo Aluminum i ka wela me ka wikiwiki, e hoʻoheheʻe koke i ka wela a paʻakikī i ka hana ʻana i ka wai hoʻoheheʻe paʻa.

Ma ka ʻaoʻao ʻē aʻe, hiki ke loaʻa nā hopena maikaʻi ʻole i ka wā welding. I nā wela kiʻekiʻe, hiki i ke kila a me ka alumini ke hana i nā mea ʻala a paʻakikī. Ua like kēia mau pūhui me nā ʻiliʻili liʻiliʻi i loko o ke kuʻi weld, e haki ana i ka pilikia. Hoʻohui ʻia, hiki ke maʻalahi ka alumini i ka oxidation, e hana ana i kahi papa o ka oxide ma kona ʻili. He wahi heheʻe kiʻekiʻe kēia ʻāpana oxide a hiki ke pale i ka hui ʻana o ke kila a me ka alumini. Inā ʻaʻole e hoʻoponopono pono ʻia, e nāwaliwali ke kaʻina weld.

Eia naʻe, mai hoʻonāwaliwali. Me nā ala kūpono a me nā mea hana, hiki ke lanakila i kēia mau pilikia, a hiki ke hoʻopaʻa paʻa ʻia ke kila a me ka alumini.

 II. ʻEhā ʻano o nā mīkini wiliwili no nā kila like ʻole - nā pono wili alumini

He mea koʻikoʻi ke koho ʻana i ka mīkini wiliwili kūpono no ka wili kila a me ka alumini. He ʻano ʻano like ʻole nā ​​mīkini wiliwili like ʻole a kūpono i nā hiʻohiʻona like ʻole. Eia nā ʻano ʻehā i hoʻohana mau ʻia:

1. Mīkini Mīkini Kūʻai Kūʻē Gas Metal (MIG Welder): He koho maʻamau no ka welding i kēlā me kēia lā

  ʻO ka MIG welder he mea hoʻohana nui ia no ka wili kila a me ka alumini. Hoʻohana ia ma ka hoʻoheheʻe ʻana i kahi uwea kuʻi e hoʻopiha i ke kaʻina a hoʻohana i nā kinoea inert e like me argon e pale i ka wahi kuʻi mai ka oxidation.

  No nā mea kila - aluminika me ka mānoanoa o 3 - 10mm, e like me nā ʻāpana pili o ka mīkini, kūpono ka MIG welder. Hāʻawi ia i ka wikiwiki wiliwili a maʻalahi ke hana. Hiki i nā poʻe hoʻomaka ke akamai ma hope o kekahi hana. Eia nō naʻe, he mea nui e hoʻohana i ka uwea welding i hoʻolālā ʻia no nā metala like ʻole e pale aku i nā pilikia i ka wili weld.

2. Gas Tungsten Arc Welding Machine (TIG Welder): No ka hana pololei

  E like me ka MIG welder, hoʻohana ka TIG welder i ke kinoea inert no ka pale. Akā ma kahi o ka hoʻoheheʻe ʻana i kahi uea e like me ka electrode, hoʻohana ia i kahi electrode tungsten e hana i kahi arc. ʻO ka pōmaikaʻi, ʻo ia ka hoʻomalu wela kūpono, ka mea e pale ai i ka alumini mai ke ahi a hoʻohua i nā wili weld ʻoluʻolu a me ka nani.

  Ke wiliwili i ke kila lahilahi - nā ʻāpana alumini, e like me nā ʻāpana uila a i ʻole nā ​​​​mea liʻiliʻi me ka mānoanoa o 1 - 3mm, a i ʻole ke ʻano koʻikoʻi ke ʻano o ka weld seam, ʻo ka welder TIG ke koho maikaʻi loa. Eia nō naʻe, ʻoi aku ka māmā o ka wiliwili ʻana a ʻoi aku ka kūpono no ka liʻiliʻi - batch, precision welding. ʻAʻole kumu kūʻai - kūpono no ka hana nui.

3. Laser Welding Machine: ʻO ke koho kiʻekiʻe no nā noi kiʻekiʻe - hopena

  Hoʻohana ka mīkini hoʻoheheʻe laser i ka kukuna laser kiʻekiʻe e hoʻoheheʻe i nā metala. Hiki i kona wela ke hoʻohui koke i ke kila a me ka alumini me nā wahi wela liʻiliʻi, e hōʻemi ana i ka deformation a me ka hoʻokumu ʻana o nā pūhui brittle.

  I ka ʻoihana kaʻa, ke kila kiʻekiʻe - pololei - nā ʻāpana alumini, a me nā ʻāpana koʻikoʻi i ke kahua aerospace, hilinaʻi pinepine i nā mīkini welding laser. Eia nō naʻe, he kumukūʻai kēia mau mīkini a koi i nā limahana kūikawā no ka hana a me ka mālama ʻana. Hoʻohana liʻiliʻi ʻia lākou i nā hale hana liʻiliʻi a i ʻole no ka hoʻoponopono ʻana i kēlā me kēia lā.

4. Friction Stir Welding Machine: The Strongman for Thick - Plate Welding

  No ke kila mānoanoa - nā ʻāpana alumini, e like me nā pilina ma waena o ke kila a me nā hale alumini me ka mānoanoa o luna o 10mm, ʻoi aku ka maikaʻi o ka mīkini wiliwili friction stir. Hoʻohana ʻo ia i kahi hāmeʻa hoʻololi kiʻekiʻe e hoʻoheheʻe a hoʻoheheʻe i nā ʻili pili o ke kila a me ka alumini, a laila hoʻomaʻalili a paʻa pū.

  ʻAʻole pono kēia ʻano welding i ka uea hoʻopiha a hoʻopau i nā hopohopo oxidation. ʻO ka hopena weld seam he ikaika a māwae - kū'ē. Eia nō naʻe, ʻoi aku ka nui o nā mea hana a hiki ke wili wale i nā mea hana maʻamau. ʻAʻole hiki ke hoʻohālikelike ʻia i nā ʻano welders mua.

 III. Manaʻo kōkua no ke koho ʻana i ka welder pono e pale aku i nā lua

Ke koho ʻana i ka mīkini wili no ke kila - alumini wili, mai ʻimi makapō i nā koho pipiʻi. E koho ma muli o kāu mau pono kikoʻī:

No ka hana liʻiliʻi, nā ʻāpana lahilahi, a i ʻole ka wili pololei, e like me ka hoʻoponopono ʻana i nā ʻāpana liʻiliʻi a i ʻole ka hana ʻana i nā mea hana liʻiliʻi, hāʻawi ka TIG welder i ka waiwai maikaʻi no ke kālā. No ka hana ʻana i kēlā me kēia lā o ke kila mānoanoa - nā ʻāpana alumini me ka koi haʻahaʻa, lawa ka MIG welder. I nā hale hana me ka hana nui a me nā koi kikoʻī kiʻekiʻe, e like me ka ʻoihana automotive a me nā ʻoihana uila, ʻoiai ke kumukūʻai o ka mīkini welding laser, hiki ke hoʻomaikaʻi i ka pono a me ka maikaʻi. No ke kuʻi ʻana i ke kila mānoanoa - nā hale alumini, ʻo ka friction stir welding machine ke koho kūpono loa.

Eia kekahi, me ka nānā ʻole i ke ʻano o ka welder āu e koho ai, pono e hoʻomaʻemaʻe pono i nā ʻili o ke kila a me ka alumini no ka wehe ʻana i nā papa oxide a me ka haumia aila ma mua o ka wili. A i ʻole, ʻaʻole hiki i ka welder maikaʻi ke hana i kahi weld maikaʻi.

Inā loaʻa iā ʻoe nā koi mīkini wili, e ʻoluʻolu e kelepona iā Ms. Zhao
