Pono ka welding alumini i nā mea kiko'ī e kūpono i kona mau waiwai kiko'ī e like me ke kiʻekiʻe o ka thermal conductivity a me ka maʻalahi i ka oxidation. Eia ka haʻihaʻi o nā mea pono i hoʻohana ʻia no ka wili alumini:

1. Nā Metala Hoʻopiha

He mea koʻikoʻi ke koho ʻana i ka metala hoʻopihapiha kūpono no ka hoʻohālikelike ʻana me ke kumu alumini alumini, e hōʻoia i nā wili leo me ka ʻole o ka pohā a nāwaliwali. Loaʻa nā metala hoʻopiha alumini maʻamau:

• 4043 Alloy (Al-Ae): Hoʻohana nui ʻia ma muli o kāna mau hiʻohiʻona kahe maikaʻi a me ke kūpaʻa māwae maikaʻi. He kūpono ia no ka wiliwili ʻana i nā alumini alumini 6xxx series akā ʻaʻole i ʻōlelo ʻia ma kahi e koi ʻia ai ka anodizing ma muli o ka hiki ke loaʻa kahi wahi weld ʻeleʻele..
• 5356 Alloy (Al-Mg): Hāʻawi i ka ikaika tensile ʻoi aku ka maikaʻi ma mua o 4043. He kūpaʻa ʻo ia i ka corrosion a kūpono no ka hoʻopaʻa ʻana i nā alloys series 5xxx. Ua like pū me ke kala o ka metala kumu ma hope o ka anodizing.
• 5183, 5556 (Al-Mg): Hoʻohana ʻia no nā welds ikaika kiʻekiʻe ma mua o 5356. Hāʻawi lākou i ke kūpaʻa maikaʻi i ka corrosion ma nā wahi kai.
• 5554, 5654 (Al-Mg): ʻO nā ʻano like ʻole me nā waiwai kikoʻī no nā kaiapuni pili i ke koʻikoʻi-corrosion.
• 4047 Alloy (Al-Ae): Loaʻa i nā silika hou aku, e hoemi ana i ka helu hehee a me ka hoonui ana i ka wai o ka wai weld, hoʻohana pinepine ʻia no nā noi e pono ai ke kahe maikaʻi i ka hui.

2. Nā kinoea pale

He mea koʻikoʻi ke koho kūpono o ke kinoea pale no ka pale ʻana i ka wahi weld mai ka haumia o ka lewa a hoʻopaʻa i ke arc.. Loaʻa nā kinoea maʻamau:

• Argon: ʻO ke kinoea pale i hoʻohana pinepine ʻia no alumini wili no ka mea, kōkua ia i ka hana ʻana i kahi arc kūpaʻa a hōʻemi i ka hana hoʻomaʻemaʻe, ka mea makemake i ka wā e wiliwili ai i ka aluminika.
• Helium a i ʻole Helium-Argon Mixtures: Hoʻohana ʻia kēia mau mea e hoʻonui i ke komo ʻana a me ka weld pool fluidity, ʻoi aku ka maikaʻi ma nā ʻāpana mānoanoa. Kōkua ʻo Helium i ka hana ʻana i kahi arc wela, hiki ke lilo i mea maikaʻi ma muli o ka conductivity wela kiʻekiʻe o ka alumini.

3. Ke Kaʻina Welding Mea Pono

Ma muli o ka ʻenehana welding, pono paha nā mea ʻē aʻe:

• TIG Welding:
  • Nā uila uila: ʻO ka maʻamau, Hoʻohana ʻia nā tungsten maʻemaʻe a i ʻole zirconiated tungsten electrodes no ka AC TIG welding o ka alumini.
  • Nā Mīkini Kuʻi AC: He mea nui ka hoʻololi ʻana i kēia manawa no ka mea e kōkua ana i ka wāwahi ʻana i ka papa oxide i hana ʻia ma luna o nā ʻili alumini.
• MIG Welding:
  • Uea wiliwili: Hoʻohana maʻamau ʻia nā uea e like me ER4043 a i ʻole ER5356 i nā wili a hānai ʻia ma o ka pū welding..
  • Nā Pu Puʻupuʻu a i ʻole Push-Pull Pu: He mea koʻikoʻi kēia no ka pale ʻana i nā pilikia hānai uea ma muli o ka palupalu o nā uea alumini.

4. Mea Hoomakaukau Ili

Pono e hoʻomaʻemaʻe maikaʻi ʻia nā ʻili alumini ma mua o ke kuʻi ʻana i mea e wehe ai i ka papa oxide a me nā mea haumia:

• Palaki (Kila kohu ʻole): Hoʻohana ʻia e holoi i ka ʻili. He mea nui ka hoʻohana ʻana i nā pulupulu i hoʻohana wale ʻia ma ka alumini e pale aku ai i ka haumia.
• Na Mea Hoomaemae Kemika: Hiki ke hoʻohana ʻia nā ʻalapona alkaline a i ʻole waika e wehe i nā oxides kaumaha a me nā aila akā pono e holoi pono ʻia i mea e pale aku ai i ka hoʻokomo ʻana i nā mea haumia i loko o ka weld..

5. Lako Palekana

Hāʻawi ʻia i ka ʻōlinolino o ke arc a me ke ʻano maikaʻi o nā uahi kuʻi alumini, he mea koʻikoʻi nā lako palekana kūpono:

• Palekana Welding pōʻeleʻele: Mālama i nā maka mai ke kukui UV ikaika.
• Nā mea hanu: ʻOi loa i ka wā e wiliwili ai i nā wahi paʻa, e pale aku i ka inha ana i ka mahu ino.
• Na Lole Hoomalu: No ka pale ʻana mai nā ʻulaʻula a me ka ʻike UV.

Using these specific materials correctly can greatly improve the quality of aluminika welds and ensure the structural integrity and longevity of the welded joints.
