2) TA2: Alpha - titanium alloy vuam hlau, nrog rau kev ua tau zoo thiab vuam kev ua tau zoo, nrog rau siab zog thiab corrosion kuj.

3) TA3: Alpha titanium alloy vuam hlau, tseem hu ua ntshiab alpha titanium vuam hlau, muaj zog thiab zoo heev corrosion kuj.

4) TA9: + - hom titanium alloy vuam hlau muaj kev ua tau zoo thiab kev ua haujlwm vuam, nrog rau lub zog siab thiab corrosion kuj.

5) TC4: Feem ntau siv titanium alloy vuam hlau nrog lub zog siab thiab zoo toughness.

 

2. Vuam txoj kev ntawm titanium vuam hlau

1) Kev npaj ua ntej vuam:

Ua tib zoo ntxuav qhov chaw ntawm qhov chaw welded thiab titanium vuam hlau kom tshem tawm cov impurities xws li oxide zaj duab xis thiab roj stains.

Xaiv cov khoom siv vuam tsim nyog thiab vuam tsis zoo, xws li vuam tam sim no, qhov hluav taws xob, vuam ceev, thiab lwm yam.

2) Kev tiv thaiv roj:

Thaum lub sij hawm vuam txheej txheem, cov roj inert (xws li argon) yog siv los ua cov roj tiv thaiv los tiv thaiv cov vuam los ntawm oxidized ntawm qhov kub thiab txias.

Xyuas kom meej qhov purity thiab ntws tus nqi ntawm cov roj tiv thaiv kom ua tiav cov txiaj ntsig zoo vuam.

3) Vuam txoj kev:

(1) Tungsten inert gas welding (GTAW/TIG): haum rau vuam titanium alloys nyias thiab nruab nrab tuab daim hlau. Los ntawm kev tsim ib qho arc los ntawm tungsten electrode, cov vuam hlau thiab cov khoom siv hauv paus yog rhuab los ua ib qho vuam seam.

(2) Gas Hlau Arc Vuam (GMAW/MIG): Txawm hais tias titanium alloy MIG vuam tsis siv dav hauv khw, nws tuaj yeem txiav txim siab rau qee lub sijhawm tshwj xeeb uas yuav tsum tau siv vuam zoo. Kev tswj kom raug ntawm kev hloov pauv hloov pauv yuav tsum tau ua kom ntseeg tau qhov zoo ntawm cov vuam seam.

(3) Plasma arc vuam (PAW): haum rau vuam titanium alloys ntawm nruab nrab thiab tuab daim hlau. Lub plasma arc tau txais los ntawm cov neeg kho tshuab compression, thermal compression, thiab electromagnetic compression muaj cov yam ntxwv ntawm kev nruj nruj thiab muaj zog nkag, uas tuaj yeem nkag mus rau tuab pob tw welds yam tsis qhib qhov zawj ib zaug.

(4) Nqus Electron Beam Vuam (EBW): Siv lub tshuab hluav taws xob nrawm nrawm los cuam tshuam cov vuam hlau thiab cov khoom siv hauv lub tshuab nqus tsev, ua kom muaj qhov kub thiab txias uas yaj cov vuam hlau thiab cov khoom siv hauv paus thiab tsim cov vuam seam. Haum rau lub sijhawm nrog cov kev xav tau siab heev rau cov khoom siv vuam zoo.

(5) Laser welding: Siv lub zog loj laser beam kom sov cov vuam hlau thiab cov khoom siv hauv paus los tsim cov vuam seam. Haum rau welding nyias-walled cov ntaub ntawv.

4) Kev kho tom qab vuam:

Ua qhov tsim nyog tshuaj xyuas thiab kev ntsuam xyuas ntawm welds kom ntseeg tau tias vuam zoo thiab kev ua tau zoo.

Ua cov txheej txheem tom ntej xws li kev kho cua sov lossis kev kho saum npoo raws li xav tau.

3. Ceev faj

1) Thaum lub sij hawm vuam txheej txheem, vuam tsis thiab txheej txheem txheej txheem yuav tsum nruj me ntsis tswj kom welding zoo thiab kev ua tau zoo.

2) Titanium alloys tshwj xeeb tshaj yog rhiab heev rau oxygen ntawm qhov kub thiab txias, yog li nws yog ib qho tsim nyog los xyuas kom meej qhov purity thiab ntws tus nqi ntawm cov roj tiv thaiv.

3) Rau cov ntaub ntawv sib txawv titanium alloy, cov txheej txheem vuam tsim nyog thiab vuam tsis zoo yuav tsum raug xaiv.

 

Muaj ntau yam khoom siv rau titanium vuam hlau, txhua tus muaj cov khoom tshwj xeeb thiab cov chaw siv. Thaum lub sij hawm vuam txheej txheem, cov txheej txheem vuam tsim nyog thiab cov kev txwv yuav tsum raug xaiv raws li cov khoom tshwj xeeb xws li cov khoom siv, thickness, vuam yuav tsum, thiab cov khoom siv. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them rau cov ntsiab lus xws li kev npaj ua ntej weld, kev tiv thaiv roj, cov txheej txheem vuam, thiab kev kho tom qab vuam kom ntseeg tau tias qhov vuam zoo thiab kev ua haujlwm zoo.
