1. Puas yog Qib 2 titanium yuav tsum muaj cov roj tiv thaiv kev vuam?
Yog lawm, Qib 2 ua lag luam ntshiab titanium tiag tiag yuav tsum tau tiv thaiv roj thaum vuam.
Titanium yog heev reactive nrog oxygen, nitrogen, thiab hydrogen ntawm qhov kub thiab txias. Txawm tias me me ntawm cov kab mob tuaj yeem ua rau embrittlement, porosity, thiab poob ntawm corrosion kuj.
Tiv thaiv lub pas dej welding: Feem ntau siv siab -purity argon (99.99%+) ua cov roj tiv thaiv thawj.
Back shielding: Sab nraub qaum ntawm lub vuam yuav tsum tau tiv thaiv nrog argon.
Post-weld shielding: Lub vuam thiab cua sov- thaj tsam cuam tshuam yuav tsum nyob hauv qab argon tiv thaiv kom txog thaum txias dua 300℃kom tsis txhob muaj xim thiab oxidation.
Yog tias tsis muaj kev tiv thaiv zoo, Qib 2 welds yuav nkig thiab ua tsis tau raws li qhov xav tau ntawm kev siv tshuab thiab corrosion.
2. Puas yog Qib 2 titanium xav tau kev kho cua sov tom qab vuam?
Feem ntau, tsis muaj kev tshaj tawm -weld heat treatment (PWHT) yog yuav tsum tau rau Qib 2 titanium nyob rau hauv ib txwm muaj.
Yog vim li cas:
Qib 2 yog kev lag luam ntshiab titanium, tsis yog nag lossis daus- cov hlau tsis muaj zog. Nws tsis cia siab rau kev kho cua sov kom muaj zog.
Vuam tsis ua rau muaj kev nyuaj siab loj lossis ua rau muaj kev puas tsuaj rau metallurgical hloov uas yuav tsum tau annealing.
Raws li -welded mechanical thiab corrosion zog yog feem ntau txaus rau feem ntau daim ntaub ntawv.
Kev kho cua sov tsuas yog xav tau hauv cov xwm txheej tshwj xeeb:
Yog hais tias lub weld muaj kab mob hnyav heev thiab yuav tsum tau txo qhov kev ntxhov siab (tsis yog rau cov welded zoo Qib 2).
Rau siab heev -corrosion los yog cov ntaub ntawv tseem ceeb ntawm cov txheej txheem uas qhov kev ntxhov siab tau teev tseg los ntawm txoj cai.
Hauv feem ntau cov txheej txheem kev lag luam thiab cov txheej txheem vuam rau Qib 2, tsis muaj kev tshaj tawm - vuam cov cua sov yog tsim nyog.
3.Dab tsi txog kev khoov thiab stamping kev ua tau zoo ntawm Qib 2?
Qib 2 unalloyed titanium yog feem ntau siv cov ntshiab titanium qib, paub txog zoo heev ductility thiab formability.
Khoov Performance
Khoov tau zoo heev: Nws tuaj yeem ua tiav me me khoov radii yam tsis muaj tawg.
High ductility: Elongation feem ntau nyob ib ncig ntawm 20% lossis siab dua, ua rau nws tsim nyog rau kev ua haujlwm txias txias.
Tsawg springback nyiam piv rau ntau lub siab - zog hlau, txawm tias me ntsis siab dua qee cov hlau mos.
Zoo tagnrho rau cov khoom uas yuav tsum tau nruj khoov, nkhaus qhov chaw, thiab tsim plhaub.
Stamping Performance
Zoo formability: Ua tau zoo nyob rau hauv txias stamping, sib sib zog nqus nqus, thiab sib sau.
Lub zog qis dua cov qib alloyed titanium, yog li nws yuav tsum muaj zog stamping tsawg.
Resistant to tearing thaum lub sij hawm deformation vim siab ductility.
Dav siv nyob rau hauv stamped qhov chaw rau tsheb, kho mob, thiab kev lag luam dav dav qhov twg formability thiab corrosion kuj yuav tsum tau.
