Kev sib raug zoo ntawm Titanium Vuam Seam Xim thiab Weld Zoo
Aug 12, 2025
Titanium yog ib qho kev siv tshuaj siv hlau nrog kev ua kom muaj zog rau cov roj av xws li oxygen, hydrogen, thiab nitrogen ntawm qhov kub. Qhov no affinity ua tshwj xeeb tshaj yog hais raws li kev siv kub nce ntxiv thaum Titanium vuam. Kev xyaum tau muaj pov thawj tias tsis ua raws li kev nqus thiab cais ntawm cov pa oxygen, thiab nitrogen los tsim cov teeb meem tseem ceeb hauv Titanium Weld txheej txheem.
Xyoo tsis ntev los no, nrog kev txhim kho kev lag luam, thiab tshwj xeeb nrog kev hloov pauv ntawm kev hloov kho thiab qhib, kuv lub teb chaws tau ua tiav hauv kev lag luam kev lag luam. Ib txhij, cov kev ua kom tseem ceeb tau tau ua nyob rau hauv vuam cov phiaj xwm xws li rajpelines. Titanium vuam yog ib qho kev sib tw vuam, thiab kev tswj hwm zoo thaum lub sijhawm vuam muaj qhov cuam tshuam loj rau ntawm weld xim. Vim yog cov khoom siv ntawm titsis weld xim, tshawb fawb txog kev sib raug zoo ntawm titanium weld xim thiab weld zoo yog qhov tseem ceeb tshaj plaws. Kev kos rau xyoo kev tshawb fawb hauv titanium vuam thiab cov ntaub ntawv tshawb fawb kev sib raug zoo ntawm titanium weld zoo thiab weld ua kom pab txhawb rau thaj chaw tshawb fawb no.
Ii. Qhov cuam tshuam ntawm titanium cov khoom ntawm titanium vuam
1. Cov teebmeem ntawm cov pa oxygen thiab nitrogen
Oxygen thiab nitrogen interstitlyly yaj nyob rau hauv titanium, ua rau muaj kev cuam tshuam loj, ua kom muaj zog dua thiab ua kom muaj zog, tab sis txo cov yas thiab tawv. Lub xub ntiag ntawm cov pa thiab cov nitrogen hauv Welds yog detrimental thiab yuav tsum zam.
2. Cov nyhuv ntawm hydrogen
Qhov kev sib ntxiv ntawm hydrogen tuaj yeem ua kom tsawg dua qhov cuam tshuam nyuaj ntawm titanium weld hlau, thaum me ntsis txo cov khoom yas. Hydride tsim kuj tseem tuaj yeem ua rau brittleness hauv kev sib koom ua ke.
3. Cov nyhuv ntawm carbon
Nyob rau hauv chav tsev kub, carbon incolves nyob rau hauv titanium, nce zog thiab txo cov pa roj oxygen thiab nitrogen. Thaum cov pa roj carbon ntau tshaj nws solubility, nws tsim nyuaj thiab brittle tic, uas ua rau lub network {} zoo li faib tawm thiab muaj feem ntau tawg. Cov qauv hauv tebchaws tau hais tias cov ntsiab lus carbon uas nyob rau hauv titanium alloys yuav tsum tsis pub tshaj 0.1%. Thaum lub sij hawm vuam, roj stains ntawm qhov chaw ua haujlwm thiab cov hlau vuam tuaj yeem nce cov ntsiab lus carbon, yog li lawv yuav tsum tau ntxuav kom huv si. III. Kev tsom xam ntawm titanium weldability
Titanium muaj cov muaj Veldability zoo heev. Vim nws cov thermal tsawg conductivity (0.041 Cal / Qib Tebchaws Mail tsuas yog nyob rau Arc cov kev sib txuas thiab kev ua kom zoo nkauj. Tsis tas li ntawd, nws cov coefficient ntawm thermal expansion (8.6 × 10-7 / degree, ntau dua li cov tshuaj carbon) loj ua rau nws cov ntaub ntawv weldability.
IV. Kev sib raug zoo ntawm Titanium Vuam Seam Xim thiab Weld Zoo
1. Cov xim hloov pauv thiab cov txheej txheem discation ntawm titanium thiab titanium alloy xaim hluav
Qhov tsis xws luag thiab lawv cov txheej txheem ntau tiam ntawm titanium alloy xaim hluav taws xob tsuas yog tsim los ntawm cov kab sib cav sib ceg tsuas yog tsim los ntawm cov hluav taws xob weld los ntawm kev puas tsuaj ntawm huab cua. Nws tsis muaj kev tiv thaiv ntawm Weld thiab thaj chaw ib puag ncig, uas tau ua rau muaj kev ruaj khov thiab nyob ntawm qhov kub. Txawm li cas los xij, Weld thiab ib puag ncig thaj chaw ntawm cov kav dej titanium nyob rau hauv lub xeev no tseem muaj lub peev xwm los nqus tau cov pa roj Oxygen thiab cov pa. Cov pa oxygen nqus tau pib pib ntawm 400℃thiab ntawm 600 degree, thiab huab cua muaj cov nitrogen ntau thiab oxygen. Raws li cov oxidation qib nce, cov xim ntawm titanium yeeb nkab weld hloov pauv thiab cov plasticity ntawm Weld txo qis. Silvery Dawb (tsis muaj oxidation), golden daj (tio, titanium pib nqus hydrogen ntawm ib ncig 250℃oxidized ti2o3), grey (mob oxidized oxidized tio2).
2. Qhov zoo ntawm titanium velds tuaj yeem raug txiav txim los ntawm cov xim saum npoo ntawm Titanium Weld.
Kuaj cov xim sib txawv thiab hardness ntawm titanium welds:
(1) cov kev sim tau qhia tias raws li Weld cov xim sib sib zog nqus, qhia txog qhov nce hauv qib ntawm oxidation, lub weld hardness nce. Cov phooj ywg - rau {- pakee cov tshuaj nyob rau hauv lub weld, xws li oxygen thiab nitrogen, tseem txo weld zoo.
(2) Tus Weldability ntawm Titanium yog ze rau nws cov tshuaj thiab lub cev cov khoom. Txawm li cas los xij, lub ntsiab lus tseem ceeb yog qhov kub thiab txias, titanium qhov kev ua haujlwm siab yog yooj yim cuam tshuam los ntawm cov cua paug. Thaum rhuab, nws nplej nthuav dav, thiab thaum welded koom ua ke txias, ib daim ntawv loj loj. Titanium muaj qhov taw tes zoo heev, ncav 1668 ± 10 degree, xav tau ntau lub zog ntau dua li cov vuam hlau. Tsis tas li ntawd, Titanium yog siv tshuaj thiab ua kom muaj ntau dua yooj yim dua nrog cov pa thiab hydrogen dua li cov hlau, sai sai reacting siab tshaj 600 degree. Ntawm 100 degree, nws nqus cov hydrogen ntau thiab oxygen, nrog hydrogen solubility kaum ntawm ntau txhiab zaus ntau dua li ntawm cov hlau. Qhov no, nyob rau hauv lem, ua cov titanium hydride, uas ua yeeb yam txo qis tawv. Gaseous impurities nce nyiam qhov kev mob khaub thuas thiab ncua kev tawg, thiab nce mustch rhiab heev. Yog li ntawd, lub purity ntawm argon siv nyob rau hauv vuam yuav tsum tsis pub tsawg tshaj 99.99%, cov av noo yuav tsum tsis pub dhau 0.039%, thiab cov hlau hydrogen ntawm lub vuam hlau yuav tsum qis dua 0.002%. Titanium cov cua sov hloov cov coefficient yog ib nrab ntawm cov hlau. Lub - rau-} hloov tshwm sim ntawm 882 degree. Thaum ntau dua qhov kub thiab txias dua, cov nplej loj hlob sai thiab ua kom tsis tshua muaj, cuam tshuam tsis meej. Yog li ntawd, kev tswj kom tuab heev yog qhov tseem ceeb, tshwj xeeb tshaj yog lub siab- kub nyob lub sij hawm vuam lub voj voog. Thaum kub tawg thiab intergranular cracking tsis yog teeb meem thaum vuam titanium, tshwj xeeb yog thaum vuam + alloys} titanium vuam ceev
Raws li cov kev tshawb fawb saum toj no, cov ntsiab lus hauv qab no yuav tsum tau sau tseg thaum Vuam Titanium:
1. Lub sijhawm titanium vuam, thaj chaw vuam thiab cov posts {}}}} qhov chaw kub, uas tuaj yeem cuam tshuam rau hauv Weld zoo. Yog li ntawd, 99.99% Ntshiab Argon thiab ib qho rov qab - Cov Khaub Ncaws Tiv Thaiv Uas Yuav Tsum Tau Ua.
2. Tus Weld Groove yuav tsum machined (sib tsoo tsis raug tso cai).
3. Chaw vuam yuav tsum zam kev zam, thiab siab- muaj arc pib yuav tsum tau siv.
4. Post {- Weld Kho Kom Sov yuav tsum zam; Yog tias tshaj tawm - Weld Kev Kho Tshav Kub yog qhov tsim nyog, cov kev kho cua sov kub yuav tsum tsawg dua 650 degree.
Kev tswj hwm zoo ntawm titanium vuam muaj qhov cuam tshuam tseem ceeb rau ntawm weld xim. Lub weld xim kuj tseem siv tau los txiav txim siab qhov zoo ntawm titanium weld. Ob tug muaj feem cuam tshuam zoo.
