Titanium alloy phaj thiab raj vuam
Titanium alloy, lub teeb yuag thiab muaj zog hlau cov khoom siv dav siv hauv aerospace, khoom siv kho mob, kev tsim tsheb thiab lwm yam. titanium alloy cov ntaub ntawv yog cov yam ntxwv zoo heev corrosion kuj, siab zog thiab zoo plasticity. Kab lus no yuav tsom mus rau cov kev paub txog cov titanium alloy daim hlau thiab titanium alloy raj thiab cov khoom siv vuam sib txuas.
Cov yam ntxwv tseem ceeb ntawm titanium alloy:
Kev tiv thaiv corrosion zoo heev: Titanium alloy muaj siab corrosion kuj rau oxides, acids, alkalis, thiab lwm yam.
Siab zog thiab qhov ceev qis: titanium alloy muaj lub zog siab thiab ceev, ua rau nws cov khoom siv tsim qauv zoo.
Tsawg melting point: Titanium alloys muaj cov ntsiab lus melting tsawg thiab yuav tsum tau vuam ntawm qhov kub siab dua.
Titanium alloy phaj, raws li lub npe qhia, hais txog lub phaj zoo li cov khoom ua los ntawm titanium alloy ua cov khoom tseem ceeb. Titanium alloy phaj yog dav siv nyob rau hauv aerospace teb vim lawv tsis tshua muaj ceev, siab zog thiab corrosion kuj. Kev tsim cov txheej txheem ntawm titanium alloy daim hlau yuav tsum nruj tswj hwm ntawm alloy muaj pes tsawg leeg thiab cov txheej txheem kev kho cua sov kom ntseeg tau tias nws cov khoom siv tau raws li qhov yuav tsum tau ua.
Thaum vuam titanium alloy daim hlau, koj yuav tsum tau xyuam xim rau cov nram qab no yam. Ua ntej, xaiv txoj kev vuam tsim nyog. Cov txheej txheem vuam feem ntau suav nrog TIG vuam, arc vuam, laser vuam, thiab lwm yam. Xaiv txoj kev vuam tsim nyog tuaj yeem txhim kho vuam zoo. Thib ob, tswj qhov vuam kub thiab ceev. Titanium alloys yog kub rhiab heev, thiab cov vuam kub ntau dhau yuav ua rau muaj kev hloov pauv hauv cov qauv hlau thiab cuam tshuam rau nws txoj haujlwm. Nyob rau tib lub sijhawm, qhov vuam ceev yuav tsum yog nruab nrab. Kev nrawm dhau los yog qeeb dhau yuav muaj kev cuam tshuam tsis zoo rau qhov zoo ntawm qhov vuam. Thaum kawg, xaiv cov khoom ntim uas tsim nyog. Cov khoom siv muab tub lim yuav tsum muaj cov tshuaj zoo sib xws thiab cov khoom siv kho tshuab rau titanium alloy kom ntseeg tau tias lub zog thiab corrosion kuj ntawm vuam.
Titanium alloy tube yog hais txog cov khoom siv tubular ua los ntawm titanium alloy ua cov khoom tseem ceeb. Titanium alloy kav yog lub teeb yuag, siab zog thiab corrosion-resistant thiab yog dav siv nyob rau hauv aviation, aerospace thiab tshuaj industries. Thaum vuam titanium alloy kav, koj yuav tsum tau xyuam xim rau cov ntsiab lus hauv qab no. Ua ntej, xaiv txoj kev sib txuas cov yeeb nkab uas tsim nyog. Cov kev sib txuas ntawm cov kav dej muaj xws li vuam, threaded kev twb kev txuas, clamp kev twb kev txuas, thiab lwm yam. Thib ob, tswj cov kev ntsuas vuam. Vuam tsis muaj xws li vuam tam sim no, vuam voltage thiab vuam ceev. Kev tswj kom tsim nyog ntawm cov ntsuas no tuaj yeem txhim kho vuam zoo. Thaum kawg, kev kho cua sov tom qab vuam yog ua. Kev kho cua sov tom qab vuam tuaj yeem tshem tawm kev ntxhov siab ntawm vuam thiab txhim kho lub zog thiab corrosion tsis kam ntawm welds.
Cov txheej txheem ntawm titanium alloy vuam:
TIG welding (GTAW/TIG): Qhov no yog ib qho kev siv phau ntawv vuam txoj kev rau titanium alloys uas muab cov welds zoo.
Plasma Arc Vuam (PAW): Vuam yog ua los ntawm kev siv plasma generated los ntawm arc, thiab yog haum rau thicker titanium alloy daim hlau.
Resistance welding: Feem ntau yog siv rau kev sib koom ua ke nyias daim hlau, vuam yog nqa tawm los ntawm cov cua sov tsim los ntawm kev ua haujlwm.
Vuam codes thiab cov qauv:
AWS D1.9/D1.9M: Qhov no yog cov lus qhia tshwj xeeb rau titanium alloy welding tawm los ntawm American Welding Society (AWS), uas suav nrog cov kev cai rau argon arc vuam thiab plasma vuam.
TS EN ISO 6848 Tus Qauv rau phau ntawv argon arc vuam ntawm titanium alloys muab los ntawm International Organization for Standardization (ISO).
ASTM B265: ASTM International tus qauv qhia tshwj xeeb rau kev tsim cov ntawv titanium alloy, sawb, thiab ntawv.
Tej yam uas yuav tsum nco ntsoov thaum welding:
Kev tiv thaiv roj inert: Titanium alloys yooj yim hnov mob nrog oxygen, nitrogen thiab lwm yam roj thaum lub sij hawm vuam, yog li yuav tsum muaj kev tiv thaiv roj inert.
Kev tswj qhov kub thiab txias: Vim qhov tsis tshua muaj melting point ntawm titanium alloys, vuam yuav tsum tau ua nyob rau hauv ib tug ntau dua kub, thiab kub heev yuav tsum tau zam kom tsis txhob oxidation.
Tsis txhob hla kev sib kis: Thaum lub sij hawm vuam, tsis txhob hla kev sib kis nrog lwm cov hlau los tiv thaiv brittleness thiab deterioration.
Thaum vuam titanium alloys, nws raug nquahu kom ua raws li cov kev qhia tshwj xeeb thiab cov qauv kom ntseeg tau tias vuam zoo thiab kev nyab xeeb. Tsis tas li ntawd, rau thaj chaw thov tshwj xeeb, cov txheej txheem vuam nruj dua yuav tsum tau txais raws li cov kev xav tau tshwj xeeb.
Txhawm rau ua kom tiav, daim ntawv thov ntawm titanium alloy cov ntaub ntawv yog sib cais los ntawm qhov tsim nyog vuam specifications. Thaum vuam titanium alloy daim hlau thiab titanium alloy raj, nws yog ib qho tsim nyog los xaiv txoj kev vuam tsim nyog, tswj cov vuam kub thiab ceev, thiab xaiv cov khoom tsim nyog los yog cov yeeb nkab txuas txoj kev. Cov kev ntsuas no tuaj yeem ua kom cov vuam zoo thiab txhim kho kev ua haujlwm thiab kev ntseeg siab ntawm cov ntaub ntawv titanium alloy.
