American Welding Society (AWS) tau tsim cov kev qhia tshwj xeeb rau ntau yam khoom siv vuam, suav nrog titanium vuam hlau. AWS A5.16 yog qhov tshwj xeeb tsim tshwj xeeb rau titanium vuam hlau. Nws qhia txog qhov yuav tsum tau muaj rau cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov txheej txheem kuaj kom ntseeg tau tias qhov zoo thiab ua haujlwm ntawm titanium welds.
ASTM B863 Titanium Vuam Hlau:
ASTM International, yav tas los hu ua American Society for Testing and Materials (ASTM), teeb tsa cov qauv rau ntau yam khoom, suav nrog titanium. ASTM B863 yog tus qauv specification rau titanium thiab titanium alloy vuam hlau. Nws npog cov kev cai rau cov tshuaj muaj pes tsawg leeg, txhua yam khoom, thiab qhov ntev ntawm cov xov hlau.
Kev sib piv ntawm Chemical Composition:
| Chemical Composition (wt.%) | ASTM B 863 | AWS A5.16 (Gr2/ERTi2) |
|---|---|---|
| Titanium (Ti) | Ntau dua lossis sib npaug li 99.2 feem pua | Ntau dua lossis sib npaug li 99.2 feem pua |
| Nitrogen (N) | - | Tsawg dua lossis sib npaug rau 0.015 feem pua |
| Cov pa roj carbon (C) | Tsawg dua lossis sib npaug rau 0.08 feem pua | Tsawg dua los yog sib npaug rau 0.03 feem pua |
| Hydrogen (H) | - | Tsawg dua lossis sib npaug rau 0.008 feem pua |
| Hlau (Fe) | Tsawg dua lossis sib npaug rau 0.30 feem pua | Tsawg dua lossis sib npaug rau 0.12 feem pua |
| Cov pa oxygen (O) | Tsawg dua lossis sib npaug rau 0.25 feem pua | {{0}}.08 ~ 0.16 feem pua |
| Aluminium (Al) | - | - |
| Vanadium (V) | - | - |
| Lwm yam impurities | Tsawg dua lossis sib npaug rau {{0}}.10 feem pua txhua, Tsawg dua lossis sib npaug rau 0.40 feem pua tag nrho | Tsawg dua lossis sib npaug rau {{0}}.10 feem pua txhua, Tsawg dua lossis sib npaug rau 0.40 feem pua tag nrho |
AWS A5.16 thiab ASTM B863 tau lees paub dav dav rau titanium vuam hlau. AWS A5.16 muab cov lus qhia tshwj xeeb, suav nrog tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab, ua kom haum rau qib sib txawv ntawm titanium. Ntawm qhov tod tes, ASTM B863 muaj cov kev cai dav dav ntxiv txog cov tshuaj muaj pes tsawg leeg thiab cov khoom siv tshuab yam tsis tau tsom rau cov qib tshwj xeeb.
Thaum xaiv ibtitanium vuam hlau, nws yog ib qho tseem ceeb los xav txog cov kev cai tshwj xeeb ntawm daim ntawv thov, nrog rau kev sib raug zoo nrog lub hauv paus hlau. Kev sab laj txog qhov tsim nyog tshwj xeeb (AWS A5.16 lossis ASTM B863) thiab ua haujlwm nrog cov neeg xa khoom thiab cov kws tshaj lij vuam tuaj yeem pab ua kom tiav kev ua tiav ntawm titanium vuam tej yaam num, ua rau muaj zog, ruaj, thiab corrosion-resistant welds.
