Kodi Mbale za Titanium Zingawotchedwe? Njira Zowotcherera ndi Njira Zabwino Kwambiri

Titaniyamu ndi chitsulo chamtengo wapatali kwambiri m'mafakitale monga mlengalenga, kukonza mankhwala, ndi uinjiniya wapamadzi chifukwa cha mphamvu zake zolemetsa, kukana dzimbiri, komanso kuyanjana kwachilengedwe. Komabe, kuwotcherera mbale za titaniyamu kumabweretsa zovuta zapadera chifukwa chakuchitanso kwambiri ndi okosijeni ndi nayitrogeni pakutentha kokwera.

Nkhaniyi ikufotokoza kaya mbale za titaniyamu zimatha kuwotcherera, njira zabwino zowotcherera, ndi njira zazikulu zowonetsetsa kuti malo olumikizirana amphamvu, opanda chilema.

Kodi Mbale za Titanium Zingawotchedwe?

Inde, mbale za titaniyamu zimatha kuwotcherera, koma zimafunikira kuwongolera mosamalitsa kuti zipewe kuipitsidwa, kusweka, ndi kuphulika. Kuchita bwino kwa kuwotcherera kumadalira:

•  Gawo lazinthu (Zamalonda Pure Titanium vs. Titanium Alloys)
•  Njira Yowotcherera (TIG, MIG, Laser, EB, Friction Stir)
•  Kuteteza Kuyera kwa Gasi (Argon kapena Helium)
•  Pre- and Post-Weld Treatments

Njira Zabwino Zowotcherera Zopangira Mbale za Titanium

TIG (GTAW) ndiyo njira yodziwika kwambiri kuwotcherera mbale za titaniyamu chifukwa cha kulondola kwake komanso kuthekera kosunga chitetezo cha gasi.

Zovuta Zazikulu Pakuwotcherera kwa Titanium

1.Kuwonongeka kwa Oxygen & Nitrogen

Titaniyamu imachita ndi mpweya pamwamba 400 ° C (752 ° F), kupanga brittle oxides.

Yankho: Gwiritsani ntchito argon oyera kwambiri (99.999%) ndi zishango zoyendera gasi.

2.Porosity & Cracking

Chinyezi, mafuta, kapena zonyansa zapamtunda zimatha kupangitsa kuti zisawonongeke.

yankho; Zoyeretsa bwino mbale (acetone + chitsulo chosapanga dzimbiri burashi).

3.Zone Yokhudzidwa ndi Kutentha (HAZ) Embrittlement

Kuzizira kofulumira kungayambitse alpha-case (brittle layer).

yankho; Kuwotcha pambuyo pa weld (ngati zingafunike).

Njira Zabwino Zowotcherera Mbale za Titanium

 Pre-Weld Kukonzekera

• Chotsani malo ndi acetone kapena mowa kuti muchotse mafuta.

• Gwiritsani ntchito maburashi achitsulo chosapanga dzimbiri (peŵani chitsulo cha carbon kuti mupewe kuipitsidwa).

 Chitetezo cha Gasi

• Sungani kuphimba kwa argon mbali zonse za weld (kutsuka kumbuyo).

• Gwiritsani ntchito magalasi a gasi kuti muteteze bwino pakuwotcherera kwa TIG.

 Kulowetsa Kutentha Kwambiri

• Pewani kutentha kwambiri kuti mupewe kufota ndi kukula kwa mbewu.

• Gwiritsani ntchito pulse TIG pama mbale woonda.

Pambuyo pa Weld Inspection

• Yang'anani mawonekedwe (udzu/chikasu = chovomerezeka; buluu / imvi = choipitsidwa).

• Kuyesa kwa X-ray kapena ultrasonic pakugwiritsa ntchito zovuta.

Kutsiliza

Ma mbale a Titaniyamu amatha kuwotcherera bwino ndi njira zoyenera, zida, ndi kusamala. Kuwotcherera kwa TIG yokhala ndi chitetezo cha argon kumakhalabe muyezo wagolide, pomwe njira zapamwamba monga kuwotcherera kwa laser ndi ma elekitironi ndizoyenera kugwiritsa ntchito molondola kwambiri.

Potsatira malamulo okhwima oyeretsera, kutchingira, ndi kuwongolera kutentha, opanga amatha kupeza ma weld amphamvu, osachita dzimbiri a titaniyamu m'mafakitale ovuta.
