Kev tsom xam ntawm kev nyuaj thiab countermeasures hauv titanium alloy vuam
Aug 12, 2025
Titanium yog xim hlau tshuaj nrog cov khoom siv tshuaj lom neeg ti thiab cov khoom siv kho mob, thiab lwm yam khoom siv kho mob, thiab lwm yam muaj zog, thiab zoo heev corrosion. Txawm li cas los xij, vim muaj cov khoom tshwj xeeb ntawm titanium alloys, vuam muab nthuav tawm qee yam kev cov nyom thiab muaj peev xwm vuam tsis xws luag.
Vuam titanium alloys yog qhov nyuaj. Cov kev nyuaj thiab muaj peev xwm vuam tsis xws luag yog qhov tseem ceeb ntawm cov hauv qab no:
Embrittlement: titanium alloys tau txais kev cuam tshuam nrog cov huab cua sov, ua rau cov pa taws, ua rau muaj cov plastatures siab thiab tawv ntawm welded sib koom tes. Yuav kom tsis txhob emgrittlement, lub vuam illosphere thiab cov kev coj dawb huv ntawm cov khoom kho yuav tsum tau tswj hwm.
Weld Cracking: Qhov tshwm sim ntawm Weld tawg hauv titanium alloys muaj feem nrog kev ntxhov siab thiab hydrogen cov ntsiab lus. Yog li ntawd, kev ntxhov siab tswj yog xav tau thaum lub vuam, overheating thiab txias txias ntawm cov khoom yuav tsum tau zam, thiab thaj chaw weld yuav tsum khaws cia kom qhuav thiab huv.
Weld Porosity: thaum lub sij hawm vuam, cov tshuaj tiv thaiv ntawm titanium alloys nrog oxide tuaj yeem yooj yim ua rau Weld Porosity, uas txo lub zog thiab kev sib khi ntawm welded sib koom tes. Ua tib zoo tswj cov ntsiab lus pa oxygen ntawm argon tiv thaiv roj thiab vuam cov ntaub ntawv, thaum ua rau lub cheeb tsam weld yog qhuav thiab huv.
Txhawm rau tiv thaiv cov teeb meem vuam sib tham saum toj no, muaj kev cuam tshuam tiv thaiv tsis ncaj ncees.
1. Xaiv cov txheej txheem vuam tsim nyog thiab xaiv cov qauv vuam uas tsim nyog raws li Titanium alloy cov ntsiab lus thiab impurity cov ntsiab lus thiab impurity cov ntsiab lus thiab impurity ntsiab lus
2. Siv siab - zoo thaiv cov roj nrog lub purity ntawm tsawg kawg 99.99%.
3. Kom huv si thiab kho cov khoom siv hauv paus thiab vuam hlau ua ntej vuam siv kom tsis txhob tawg thiab cuam tshuam.
4. Thaum vuam, siv tsim nyog argon tiv thaiv argon tiv thaiv thaj chaw weld thiab kub}}} cuam tshuam cheeb tsam ntawm weld kom ntseeg tau weld zoo.
Ua ntej - weld npaj:
Kev kho deg: kho lub cev kho cov titanium alloy nto, suav nrog cov hauv kev xws li sandblasting thiab polishing, kom tshem tawm nplaim av av thiab oxide txheej. Qhov no txhim kho weld zoo thiab kev ntseeg tau.
Kev Kho Mob Siv Tshuaj: Tshuaj lom neeg xws li cov acids thiab alkalis tau siv los yaj thiab tshem tawm cov av av thiab oxides. Tshuaj lom neeg tshuaj pab txhim kho cov khoom zoo thiab cov khoom ntawm Weld sib koom tes.
Kev ntxuav thiab ziab: kom ntseeg tau lub chaw weld yog qhuav thiab huv kom tsis txhob muaj qhov porosity thiab lwm yam tsis meej. Siv tshuab ziab khaub ncaws lossis cua sov ua kom tsim nyog kom ua kom tau qhov tseeb thiab av noo hauv lub chaw vuam.
Cov Qauv Vuam:
Ntshav Arc Vuam: lub siab {{0} {} Lub Zog Plasma ARC yog siv los ua kom sov thiab yaj lub titanium alloy, feem ntau siv DC ARC. Ntshav Arc Vuam muab lub zog loj thiab vuam ceev, ua rau nws haum rau thicker titanium alloy daim hlau thiab welds loj.
Roj tungsten arc vuam (gtaw): ib txoj kev sib tw ua ntej: ARC VUAM txoj kev siv A {{melting tungsten electrode. Thaum GTaw, thaj chaw weld yog daim thaiv los ntawm cov kev tiv thaiv cov pa hluav taws xob (feem ntau yog cov roj av xws li Argon), thiab cov tub rog sib dhos (weld hlau) feem ntau siv.
Nws siv lub tshuab arch los ntawm kev sib tw weld. Mig vuam yog yooj yim los ua haujlwm thiab haum rau vuam tuab titanium alloy daim phiaj thiab cov qauv loj.
Roj Tungsten Arc Vuam (Tig): A TIGTEN Electrode yog siv los ua kom sov thiab yaj lub titanium alloy, thaum Argon Gas Shields Weld cheeb tsam. Tigding muaj cov siab weld zoo thiab tswj, ua rau nws haum rau nyias daim hlau thiab precision vuam.
Nqus plua plob welding: Siv hluav taws xob ci ntsa iab hauv qab lub tshuab nqus dej, titanium alloys yog rhuab thiab melted. Nqus plua plob welding muaj cov high vuam maj thiab weld zoo, ua rau nws haum rau cov qauv tower titanium.
Lub tuam txhab khav ua cov khoom lag luam hauv tsev titanium ua ntau lawm, nrog rau:
German -} imported precision titanium raj ntau lawm kab (txhua xyoo tsim muaj peev xwm: 30,000 tons);
Japanese -} technology titanium ntawv ci rolling kab (thinnest rau 6μm);
Qoos motated titanium qws txuas ntxiv mus rau kab extrusion;
Ntse titanium phaj thiab sawb fining;
MES system ua noj digital tswj thiab kev tswj hwm ntawm tag nrho cov txheej txheem ntau lawm, ua tiav cov khoom lag luam seem ntawm ± 0.01M.
