ʻO nā sampbuilders a me nā papa inoa o ka hoʻohanaʻana i ka hana alumini a me nā condosinim no ka paleʻana o ka corrosion:

• Moku i nā Hulls a me Superstructure: 5083 and 5 xxx alloys weld me ka hōʻemi haʻahaʻa haʻahaʻa, E hoʻopau i nā nui o nā helu pākuʻi nui (a i 10 m) a hōʻemi i ka wā o ka hālāwaiʻana ma 20%.
• Nā ipu koʻikoʻi & ʻO nā pahu cryogenic: E like me 5083 and 6061 WELL ma Tig i loko o nā lewa i mālamaʻia, e hana ana i nā hui likak-paʻa i ka hana -196 ° C lawelawe ma LNG noi.
• Kumuku'āina: Hoʻomoʻa i nā lāʻau hoʻonaninani i loko 6 ʻO nā mea hou-Serix-Series Extrussions.
  ʻO Laser ka uē hou i nā'āpana'ē aʻe i lalo 0.5 mm, hana i ka flush, Nā papa i mākaukauʻia.

Ke kū nei i nā'āpana: Nā kaʻa uila & Ka ikehu hou

E like me ka pivot o nāʻoihana, Kākoʻo kōkuaʻo Aluminim i nāʻenehana hou:

• ʻO ka makaniʻo Turbine Hubs: ʻO nā mea nuiʻo FSW (a i 50 mm) 6 ʻO nā papa inoa XXX-Series no ka Turbine Blade Blade Bootings 300 Mpa a ola loa ka momona 10⁷ nā kupu ma lalo o ka laweʻana i ka cyclic.
• ʻO nā FOLLAR TOCKER FIELD: Mig-welded 5 ʻO XXX Extrussions i nā mea kākoʻo kākoʻo palekana, hoʻemi i nā kumukūʻai kālā e 25% ua hoʻohālikelikeʻia i nā pahu kila galvanized.
• ʻO nā cylinders mālama hydrogen: ʻO nā mea kūʻai aku a me ka laser a me ka laser 6 xxx alloys seft seamless, nā kīʻaha kiʻekiʻe, Mālama palekana, E hoʻohālikelike i nā pahu Hydrogen no nā kaʻa Upel-cell.

11. Loaʻa a me nā hemahema o ka umuni

Hāʻawiʻo Aluminim i nā pōmaikaʻi nui akā e hōʻike pū ana i nā pilikia kūʻokoʻa e pono ai nā mea pāʻani e hoʻokele pono.

Loaʻa:

• Nā kukui māmā: Ua kaupaonaʻia nā hui alumini a Alminim 50 % ua emi ma lalo o nā hana kila likeʻole, Hoʻopili i ka hana pono i nā kaʻa, Kōkua, and Marine Kāleka.
• Ke kū'ē neiʻo Corrosionion: I ka wā i huiʻia me nā mea hoʻohui hoʻohui (E.g., Er5356 ma 5xxx Series),
  Mālamaʻo Aluminim.
• Ke hoʻohanaʻoihana kiʻekiʻe: ʻO nā kaʻina hana hou e like me ka fricetion stir westing maʻamau e loaʻa ana i ka 95-100 % o ka ikaika o ke kumu, e hiki ai i nā noi e hāʻawi ana i nā noi.
• Maikaʻi maikaʻi thermal: Hoʻemiʻo Rapid i ka hoʻohemoʻana i ka wela i ka nui, ʻO ka hōʻemiʻana i nā'āpana i nā'āpana likeʻole ke kāohi ponoʻia nā parameters.
• Recyclability a me ka mālamaʻana: ʻO ka aluminum scrap mai weld spatter a me nāʻokiʻoki i hoʻopili houʻia i ka ipu hao maʻalahi, ke kākoʻo nei i ka hanaʻana i ka manawa 95 % ka mālamaʻana i ka ikehu ma luna o ka hana mua.

Loaʻa nā hemahema:

• Hoʻolālāʻo Onede Trege: Ua koiʻia nā kiʻiʻoniʻoni Al₂o₃ (kemika a me ka mīkini) and, i tig, AC Polarity e hōʻoia i ka wikiwiki.
• ʻO ka wela wela: ʻOiai ke kiʻekiʻe o ka laweʻana i ka mana o ka maʻi maʻi, ʻO nā mea waiwai e hoʻonui ai i ka nui o ka nui o ka nui o ka nui o ka puhiʻana i ka puhiʻana i nā'āpana wela a me nā'āpana wela i nā'āpana he nui.
• Haz e hoʻonāukiuki i nā alloys wela: Hoʻopiliʻo Fusion i nā 6xxx a me 7xxx Series pinepine i ka hoʻoikaikaʻana i nā hanaʻino,
  ka hopena i kahi wahi i hoʻopaʻaʻia e koi ai i nā hana a me nā kaʻina hana a iʻole nā ​​kaʻina hana e like me ka FSW.
• ʻO kaʻoluʻolu a me nā kūlana kaumaha: ʻO ka hoʻonuiʻiaʻo Aluminim kiʻekiʻe a me nā haʻahaʻa haʻahaʻa haʻahaʻa elastic a me nā mea elastic haʻahaʻa e hoʻohui ai i ke kauaʻana; ʻO ke ola kūpono a me nā hoʻolālā wela-wela i lilo i mea pono ai.
• Nā mea hana a me nā koi pono: Ke loaʻa nei ka loaʻaʻana o ka hoʻopunipuni manuahi-manuahi, Nā mea kiʻi kiʻi kūikawā,
  a me nā mea hana maʻamau (E.g., ʻO nā mea hana maikaʻi loa i nā lako mana, FSW Rigs), ka hoʻonuiʻana i ke kālā a me nā kumukūʻai aʻo.

12. Hopena

ʻO ka uluminum ulding e hoʻohana i nā manawa kūpono a me nā paʻakikī. Ma ke kākauʻana i ka metallim a Alminim, Ke kohoʻana i ke kaʻina kūpono,

E lilo ia i tig no ka pololei, Mig no ka huahana, a iʻole fsw no ka defect-free, ʻO nā pūpū ikaika-ikaika-a ikaika loa e hoʻopaʻa i nā parameter a me nā lāʻau lapaʻau, Loaʻa nā mea hana i ka hilinaʻi, nā hana kiʻekiʻe.
