ʻO wai ka lako maikaʻi no ka wiliwili ʻana i nā Aluminum Alloys? Hiki i ka Oxidation ke hana?

He māmā a ikaika ka alumini alumini, e hoʻohana nui ʻia i nā kaʻa, nā mea hana hale, a me nā ʻāpana mokulele. Eia nō naʻe, paʻakikī ka poʻe he nui i ka wā e wili ai i ka alumini alumini: ʻo wai nā mea pono e koho ai, a pehea lā lākou e pale aku ai i nā pilikia oxidation? I kēia lā, e wehewehe pololei wau e kōkua iā ʻoe e koho i nā lako kūpono a pale i nā pilikia o ka oxidation i ka wili alumini alumini.

 I. Ke koho ana i na lako pono no ka wiliwili alumini

Nui nā koho mea hana wili no ka alumini alumini. Ma ke ʻano he mea hana i nā mea welders wahi, nā mīkini welding laser, a me nā mīkini wili laser robotic, maopopo mākou i ka ikaika o kēlā me kēia ʻano. Hiki iā ʻoe ke koho ma muli o ka nui o kāu hana a me nā koi pono:

1. Spot Welder: ʻO ke koho maikaʻi loa no ka hoʻoheheʻe ʻia ʻana o ka huila Aluminum Alloy Batch

  - Hoʻohana nā mea welder wahi alumini alumini i nā electrodes e hoʻopili i ke kaomi a hoʻohua i ka wela ma o ka hoʻopili ʻana i ka hoʻoheheʻe ʻana e hoʻoheheʻe i ka alloy a hana i kahi weld point. ʻO ka pōmaikaʻi ka wikiwiki; ʻO kēlā me kēia helu weld e lawe wale i ka 0.1-1 kekona. He mea maikaʻi kēia no ka alumini alumini paʻa lahilahi (0.1-3 mm) i ka hui kuʻi ʻana, e like me nā ʻāpana alumini alumini i nā pahu mea hana hale a me nā ʻāpana alumini liʻiliʻi.

  - Eia nō naʻe, ʻoi aku ka conductive alumini alumini a hoʻopau koke i ka wela. Pono ʻoe i kahi welder kikoʻī me nā ʻāpana kuʻi kiʻekiʻe a me ka pōkole pōkole e pale aku i ka hoʻopili piha ʻole. Hiki i nā electrodes ke oxidize a mae ma muli o ke kiʻekiʻe o ka wela, no laila pono ka wili maʻamau a i ʻole ka hoʻololi ʻana no ka mālama ʻana i ka wili paʻa.

2. Laser Welding Machine: Pono no ka High-Precision Aluminum Alloy Weld

  - Hoʻohana nā mīkini hoʻoheheʻe laser i kahi kukuna laser ikaika nui e hoʻoheheʻe i ka alumini alumini. He liʻiliʻi loa ka wahi i hoʻopili ʻia i ka wela, e ʻae i ka mana pololei o ka weld seam. ʻO ka hopena weld seam he laumā a koi liʻiliʻi a ʻaʻole paha ma hope o ka weld. Hiki iā ia ke wiliwili i ka alumini alumini mai ka 0.05-8 mm mānoanoa a kūpono i nā noi kiʻekiʻe a me nā hiʻohiʻona koʻikoʻi, e like me nā papa alumini alumini i nā smartphones a me nā ʻāpana mea kani.

  - I ka wā e wiliwili ai i ka alumini alumini, e koho i ka mīkini wiliwili laser me ka hana pulse e hōʻemi i ka hoʻokomo wela a pale i ka deformation. Eia kekahi, e hoʻohana i ka pale kinoea argon e pale i ka oxidation i ka wā wili, e hōʻoia i ka ikaika weld a me ka helehelena.

3. Robotic Laser Welding Machine: ʻO ke koho i makemake ʻia no ka Welding Aluminum Alloy maʻamau ʻano nui.

  - Hoʻohui nā mīkini hoʻoheheʻe laser robotic i ka wiliwili laser me nā lima robotic e hoʻokō ai i ka wili a me ka maʻamau, hiki ke hoʻomau i ka hana 24-hola. Paʻa ka pololei o ka welding a ʻaʻole i hoʻopilikia ʻia e ka ʻokoʻa o ka hana kanaka, kūpono ia no ka wiliwili alumini alumini nui, e like me ka hana ʻana o nā puka kaʻa alumini alumini a me nā ʻāpana chassis i ka ʻoihana kaʻa.

  - Hiki iā ia ke lawelawe i kahi ākea ākea o ka mānoanoa alumini alumini a me nā trajectories wili paʻakikī, e like me nā welds circumferential ma nā ʻāpana alumini alumini like ʻole, e kūpono ana i nā ʻoihana e nānā ana e hoʻonui i ka hana a hoʻemi i nā kumukūʻai hana.

4. Nā Lako Kuʻuna: Hoʻokō i nā Pono Kūlohelohe

  - TIG Welder: E hoʻohana i ka electrode tungsten e hana i kahi arc, me ke kinoea argon e pale ana i ka wai hoʻoheheʻe. Pono ia i ka hānai uea manual. Hāʻawi ia i ka hoʻomalu wela kūpono a me nā welds aesthetically leʻaleʻa, kūpono no ka alumini alumini paʻa lahilahi (0.5-5 mm) i ka wili pololei, e like me nā mea hoʻonaninani alumini a me nā ʻāpana liʻiliʻi. Eia nō naʻe, he haʻahaʻa haʻahaʻa ka hana kuʻi ʻana a ʻoi aku ka maikaʻi no ka hana liʻiliʻi.

  - MIG Welder: Loaʻa nā hiʻohiʻona hānai uea maʻalahi, me ka wikiwiki o ka welding 3-5 mau manawa ʻoi aku ka wikiwiki ma mua o ke kuʻi ʻana o TIG. He kūpono ia no ke alumini alumini mānoanoa (3-20 mm) i ka hui kuʻi ʻana, e like me nā paipu alumini alumini a me nā papa hana. Eia nō naʻe, pono ke kinoea argon maʻemaʻe kiʻekiʻe (99.99%+) e pale i ka porosity.

 

II. ʻO nā pilikia o ka hoʻoheheʻe ʻana i ka hoʻoheheʻe alumini alumini a pehea e pale aku ai iā lākou

Nui ka poʻe hopohopo e pili ana i ka oxidation i ka wā e wili ai i ka alumini alumini. ʻO kēia ma muli o ke ʻano o ka alumini alumini, akā me ka ʻike kūpono a me ka pale ʻana, hiki ke pale maikaʻi ʻia:

1. Ke Kumu o ka Oxidation

  - Hoʻopili koke ka ʻili o ka alumini alumini me ka ea e hana i kahi papa oxide (ʻoi aku ka nui o Al₂O₃), nona kahi helu heheʻe a hiki i 2050°C, ʻoi aku ka kiʻekiʻe ma mua o ka helu heheʻe ponoʻī o ka alloy (ma kahi o 660°C). Inā ʻaʻole i wehe pono ʻia kēia papa okisa ma mua o ka hoʻoheheʻe ʻana, e komo ia i loko o ka loko i hoʻoheheʻe ʻia, e hoʻokomo ai i ka pala a me ka porosity i loko o ka weld seam. Hoʻopilikia pū ia i ka hui ʻana o ka alloy, e pili ana i ka ikaika weld. Eia kekahi, i ka wā wili, inā ʻaʻole mālama pono ʻia ka loko i hoʻoheheʻe ʻia, e hoʻomau ka oxygen i ka lewa me ia, e hoʻonui ana i ka oxidation.

2. Nā Hana Nui e Kāohi i ka Oxidation

  - E hoʻomaʻemaʻe maikaʻi i ka papa oxide ma mua o ka hoʻopaʻa ʻana: palaki me ka mechanically i ka ʻili o ka aluminika me kahi pulupulu uea kuhili ʻole a i ʻole e hoʻomoʻi iā ia i loko o kahi mea hoʻomaʻemaʻe alumini alumini kūikawā e hoʻoheheʻe i ka papa okisa. Ma hope o ka hoʻomaʻemaʻe ʻana, hoʻopau i ka kuʻi ʻana i loko o 4 mau hola e pale ai i ka lua o ka oxidation.

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