Titanium yog cov tshuaj lom neeg uas nws daim ntawv hlau muaj cov khoom siv cim lub cev thiab tshuaj lom neeg. Titanium alloy ua si lub luag haujlwm tsis tseem ceeb hauv Aerospace, cov khoom siv kho mob, muaj kuab lom thiab kev lag luam siv tshuaj lom neeg thiab muaj zog thiab zoo heev corrosion. Txawm li cas los xij, cov txheej txheem vuam ntawm titanium alloys ntsib ntau yam kev cov nyom thiab muaj peev xwm tej yam tsis xws luag vim nws cov khoom tshwj xeeb.
Lub ntsiab nyuaj thiab muaj peev xwm tsis xws luag nyob rau hauv vuam titanium alloys muaj xws li:
1. Mebrittlement tshwm sim: titanium alloys muaj kev tawm tsam nrog cua tshuab hluav taws xob, nitucing ntawm welded pob qij txha thiab txo lawv cov plasticity thiab nruj. Txhawm rau zam dhau qhov kev tshwm sim no, cov vuam thiab cov khoom siv purity yuav tsum tau ua nruj me ntsis tswj tau.
2. Vuam cracks: cov kab nrib pleb muaj feem cuam tshuam nrog cov kev ntxhov siab thiab hydrogen cov ntsiab lus. Yog li ntawd, nws yog qhov tsim nyog los tswj cov kev ntxhov siab thaum lub sijhawm vuam, tsis txhob txias thiab txias sai sai ntawm cov khoom siv, thiab thaj chaw vuam yog qhuav thiab huv.
3. Vuav porosity: cov tshuaj tiv thaiv ntawm titanium alloy thiab oxides yog luag porosity, cuam tshuam rau lub zog thiab sib khi ntawm welded pob qij txha. Los ntawm kev tswj cov ntsiab lus argon kev tiv thaiv thiab cov pa oxygen ntawm cov khoom siv vuam muag, nrog rau kom muaj kev siv vuam yog qhuav thiab muaj peev xwm txo cov porosity.
Txhawm rau tiv thaiv tsis xws luag nyob rau hauv titanium alloy vuam, ntsuas hauv qab no yuav tsum tau ua:
1. Xaiv cov txheej txheem vuam tsim nyog thiab cov hlau vuam: raws li cov ntaub ntawv thiab impurities ntawm titanium alloy cov qauv vuam thiab vuam hlau tsim nyog thiab vuam hlau.
2. Siv cov roj tiv thaiv zoo: xyuas kom meej tias qhov kev coj dawb huv tsis tsawg tshaj li 99.99% los xyuas kom cov nyhuv welding.
3. Kev tu thiab kho ua ntej vuam: kom huv si huv si huv si thiab kho cov khoom siv hauv paus thiab vuam hlau kom tsis txhob tawg thiab interlayers.
4. Kev tiv thaiv kev tsim nyog tsim nyog: Tiv thaiv cov pas dej thiab cov cua sov ntawm cov roj weld nrog kom cov vuam zoo.
Nyob rau hauv kev npaj preach theem, cov ntsiab lus hauv qab no yuav tsum tau sau tseg:
- Cov kev kho mob saum lub cev: cov kev siv lub cev xws li khau khiab, kom tshem cov av thiab lwm yam, kom tshem tawm cov av ntawm titanium alloy, txhawm rau txhim kho versony, txhawm rau txhim kho virtual zoo thiab kev ntseeg tau.
- Tshuaj lom neeg: Siv tshuaj yeeb tshuaj xws li cov kua qaub thiab alkalis kom yaj thiab oxides rau ntxiv txhim kho cov khoom zoo thiab cov yam ntxwv ntawm welded pob qij txha.
- Kev tu thiab ziab: Xyuas kom pom tias qhov chaw vuam yog qhuav thiab huv kom tsis txhob muaj qhov porosity thiab lwm yam tsis meej. Siv lub cub cub qhuav lossis cov khoom siv cua sov uas tsim nyog kom ntseeg tau qhov kub thiab cov av noo hauv qhov chaw vuam.
Feem ntau siv titanium vuam txoj kev muaj xws li:
- Ntshav ARC Vuam: Haum rau thicker titanium alloy daim hlau thiab loj weldments nrog lub zog siab ntom thiab vuam ceev.
- Tungsten Gas thaiv cov thaiv arc vuam (gtaw vuam): thaiv cov pa tsis huv ntawm cov pa roj av los ntawm kev thaiv pa roj, feem ntau siv nrog kev sib tsoo.
- Fused Arcon Vuam (Mig Vuam (Mig Vuam): Yooj yim ua haujlwm, haum rau thicker titanium alloy daim hlau thiab cov qauv loj vuam.
- Tungsten Argon Arc Vuam (Tig Vuam): Nrog siab vuam zoo thiab tswj, tshwj xeeb yog tsim nyog rau nyias daim hlau thiab precision vuam.
- Siv hluav taws xob nqaj war
