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. Lub a awinity no ua tshwj xeeb tshaj plaws thaum titanium vuam, raws li kev siv kub nce. Ua tsis tiav kev nqus cov nqus thiab kev sib cais ntawm cov roj av no los ntawm titanium thaum lub sij hawm vuam tuaj yeem tsim cov teeb meem vuam tseem ceeb hauv cov txheej txheem Valanium Weld.
Xyoo tsis ntev los no, nrog kev txhim kho kev lag luam, Kuv lub teb chaws tau ua tiav kev nce qib hauv Vuam rau raj xa dej thiab lwm yam haujlwm. Titanium vuam yog ib txoj kev vuam vuam. Tswjhwm zoo thaum Titanium Vuam muaj qhov cuam tshuam tseem ceeb rau ntawm Weld xim. Vim yog cov khoom siv ntawm Titanium Weld xim, kawm qhov kev sib raug zoo ntawm titanium weld xim thiab weld zoo yog qhov tseem ceeb tshaj plaws.
I. Cov nyhuv ntawm titanium cov khoom ntawm titanium vuam
1. Cov nyhuv ntawm cov pa thiab cov pa roj oxygen: oxygen thiab nitrogen increrstionly, thiab ua kom muaj zog dua thiab ua kom muaj zog, thaum txo cov plasticity thiab tawv. Lub xub ntiag ntawm cov pa thiab cov nitrogen hauv welds yog detrimental thiab yuav tsum zam dhau kev cuam tshuam ntawm hydrogen ntawm titanium weld hlau thiab me ntsis txo nws cov vasivity. Hydride tsim kuj tseem tuaj yeem ua rau brittleness hauv kev sib koom ua ke.
3. Cov nyhuv ntawm cov pa roj carbon: ntawm chav ntsuas kub, carbon interolves nyob rau hauv titanium, nce zog thiab txo cov pa thiab nitrogen. Thaum cov qib carbon ntau dua nws cov solubility, nws ua nyuaj thiab khov kho, uas ua rau lub network li kev faib tawm thiab muaj feem ntau tawg. Cov qauv hauv tebchaws coj tau hais tias cov ntsiab lus carbon hauv titanium thiab nws cov 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.
Ii. Kev tsom xam ntawm titanium weldability
Titanium muaj cov muaj Veldability zoo heev. Vim nws cov thermal tsawg conductivity (0.041 Cal / Qib Siab Melts tsuas yog nyob rau Arc cov kev sib txuas ua ke thiab ua kom zoo nkauj. Tsis tas li ntawd, Titanium muaj qhov qis coefficient ntawm thermal expansion (8.6 × 10-7 / degree), deb txhawb nqa nws lub weldability ntau. III. Kev sib raug zoo ntawm Titanium Vuam Seam Xim thiab Weld Zoo
1. Titanium Weld xim hloov pauv thiab tsis muaj peev xwm tiv thaiv cov huab cua, tab sis tsis muaj kev tiv thaiv rau cov kev sib cav sib ceg tab sis kub weld seam thiab nws cov cheeb tsam kub. Nyob rau hauv lub xeev no, Titanium Weld Seam thiab nws cov cheeb tsam ib puag ncig tseem muaj lub peev xwm los nqus cov pa hluav taws thiab oxygen los ntawm huab cua. Cov pa oxygen tso cai pib ntawm 400 degree, thiab nitrogen nqus pib ntawm 600 degree. Raws li cov qib ntawm oxidation nce, cov xim ntawm titanium weld hloov pauv, thiab weld plasterity txo. Cov xim hloov xim yog: Silvery Dawb (tsis muaj oxidation), oxidation (tieces), xiav (TiT2O), thiab Grey (TiO2, ntau dua oxidized).
2. Kev txiav txim siab weld zoo los ntawm cov xim titanium ntawm cov khoom siv rau Weld, qhia txog kev nce qib Weld, kev siv Weld hardness nce. Qhov nce hardness ntawm titanium hlau txhais tau tias kev nce ntxiv xws li oxygen thiab nitrogen nyob rau hauv weld, uas tuaj yeem txo qis weld zoo.
IV. Titanium Vuam Ceev Kev Tiv Thaiv
Raws li cov kev tshawb fawb saum toj no, cov kev ceev faj hauv qab no yuav tsum tau coj thaum vuam titanium hlau:
1. Lub sijhawm titanium vuam, ntawm thaj chaw weld thiab cov pos}} weld siab {}}}}}}}}}}}}}}}}}}}}}}}} pa taws, uas tuaj yeem cuam tshuam weld zoo. Yog li ntawd, kev siv 99.99% Cov Ntshiab Argon thiab ib qho rov qab {{6} }rd cov ntaub thaiv yog qhov tseem ceeb.
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.
Hauv cov ntsiab lus, kev tswj hwm zoo ntawm titanium vuam muaj qhov kev cuam tshuam tseem ceeb ntawm Weld xim. Tsis tas li ntawd, chav weld tuaj yeem siv los ntsuas qhov zoo ntawm titanium vuam. Ob tug muaj feem cuam tshuam zoo.
