Na Lipoleiti tsa Titanium li ka Chesoa? Mekhoa ea ho Welding le Mekhoa e Molemo ka ho Fetisisa

Titanium ke tšepe ea bohlokoa haholo liindastering tse kang sefofane, lisebelisoa tsa lik'hemik'hale, le boenjiniere ba leoatleng ka lebaka la tekanyo ea eona e ikhethang ea boima ba 'mele, ho hanyetsa kutu, le ho lumellana ha lintho. Leha ho le joalo, lipoleiti tsa tjheseletsa tsa titanium li hlahisa liphephetso tse ikhethang ka lebaka la ts'ebetso ea tsona e phahameng ea oksijene le naetrojene mochesong o phahameng.

Sengoliloeng sena se hlahloba hore na lipoleiti tsa titanium li ka chesoa, mekhoa e metle ka ho fetisisa ea ho cheselletsa, le mekhoa ea bohlokoa ka ho fetisisa ea ho netefatsa manonyeletso a matla, a se nang sekoli.

Na Lipoleiti tsa Titanium li ka Chesoa?

Ee, lipoleiti tsa titanium li ka chesetsoa, ​​empa li hloka taolo e tiileng ea ts'ebetso ho qoba tšoaetso, ho peperana le ho senyeha. Katleho ea welding e itšetlehile ka:

•  Material Grade (Commercially Pure Titanium vs. Titanium Alloys)
•  Mokhoa oa ho Welding (TIG, MIG, Laser, EB, Friction Stir)
•  Tšireletso ea Khase e sireletsang (Argon kapa Helium)
•  Liphekolo tsa Pele le ka morao ho Weld

Mekhoa e Molemohali ea ho Welding bakeng sa Lipoleiti tsa Titanium

TIG (GTAW) ke mokhoa o atileng haholo bakeng sa tjheseletsa lipoleiti tsa titanium ka lebaka la ho nepahala ha eona le bokhoni ba ho boloka tšireletso ea khase.

Mathata a ka Sehloohong ho Welding ea Titanium

1. Tšilafalo ea Oxygen & Nitrogen

Titanium e arabelana le moea o ka holimo 400 ° C (752 ° F), ho etsa li-brittle oxides.

Tharollo: Sebelisa argon ea bohloeki bo phahameng (99.999%) 'me lithebe tse tsamaisang khase.

2.Porosity & Cracking

Mongobo, mafura, kapa litšila tse ka holimo li ka baka likheo.

tharollo: Hloekisa lipoleiti ka ho feletseng (acetone + brush ea tšepe e sa hloekang).

3.Maemo a Amehiloeng ke Mocheso (HAZ).

Pholiso e potlakileng e ka lebisa ho alpha-case (brittle layer).

tharollo: Ka mor'a weld annealing (haeba ho hlokahala).

Mekhoa e Molemohali ea ho Cheselletsa Lipoleiti tsa Titanium

 Tokisetso ea Pele ho Weld

• Hloekisa libaka ka acetone kapa joala ho tlosa oli.

• Sebelisa borashe ba tšepe e sa hloekang (qoba tšepe ea carbon ho thibela tšilafalo).

 Tšireletso ea Khase ea Tšireletso

• Boloka tšireletso ea argon mahlakoreng ka bobeli a weld (ho hloekisa ka morao).

• Sebelisa lilense tsa khase ho itšireletsa hamolemo ho tjheseletsa ea TIG.

 Kenyelletso ea Mocheso e Laolehileng

• Qoba mocheso o feteletseng ho thibela ho khopama le ho hōla ha lijo-thollo.

• Sebelisa pulse TIG bakeng sa lipoleiti tse tšesaane.

Tlhahlobo ea Post-Weld

• Sheba hore na ho na le ho fifala ha mmala (mohlaka/mosehla = ho amoheleha; boputsoa/bohlooho = bo silafetse).

• Etsa tlhahlobo ea X-ray kapa ea ultrasonic bakeng sa lits'ebetso tsa bohlokoa.

fihlela qeto e

Lipoleiti tsa Titanium li ka chesetsoa ka katleho ka mekhoa e nepahetseng, lisebelisoa le litemoso. TIG welding e nang le tšireletso ea argon e lula e le maemo a khauta, athe mekhoa e tsoetseng pele joalo ka laser le electron beam welding e loketse bakeng sa lisebelisoa tse nepahetseng haholo.

Ka ho latela melaoana e tiileng ea ho hloekisa, ho sireletsa le ho laola mocheso, bahlahisi ba ka fumana litšepe tsa titanium tse matla, tse sa jeng bakeng sa liindasteri tse boima.
