Titanium-steel composite phaj, uas muaj ob qhov zoo ntawm titanium alloys thiab hlau, yog dav siv nyob rau hauv marine, shipbuilding, mechanized chemical thiab lwm yam kev lag luam teb, thiab vuam tshuab tau ua lub luag hauj lwm tseem ceeb irreplaceable nyob rau hauv cov txheej txheem ntawm nws nce qib thiab daim ntawv thov.
Tam sim no txoj kev tsom xam ntawm vuam tshuab rau titanium-steel clad phaj
Rau kev vuam ntawm titanium-steel clad daim hlau, yuav ua li cas thiaj li txo tau cov tshuaj tiv thaiv alloying ntawm titanium clad txheej thiab steel puag txheej thaum lub sij hawm vuam txheej txheem, thiaj li yuav txo tau cov tiam ntawm brittle Ti-Fe intermetallic tebchaw, thiab tib yam. lub sij hawm txo los yog txawm zam qhov teeb meem ntawm dilution ntawm titanium clad txheej Nws yog tus yuam sij kom paub txog nws cov high-strength thiab txhim khu kev qha kev twb kev txuas. Tam sim no, ib txoj hauv kev tseem ceeb yog kom tsis txhob muaj kev sib cuag ncaj qha ntawm titanium thiab hlau los ntawm txheej txheej vuam los ntawm cov qauv sib txawv; Lwm txoj hauv kev yog ntxiv cov txheej txheem hloov pauv thaum lub sij hawm vuam los tiv thaiv titanium ncaj qha kev sib cuag nrog hlau, thiaj li paub txog kev tswj ntawm microstructure thiab kev ua haujlwm ntawm kev sib koom ua ke; Tsis tas li ntawd, txhawm rau txhim kho kev ua haujlwm ntawm clad phaj vuam, qee cov kws tshawb fawb sim siv laser ib zaug nkag mus ua kom muaj txiaj ntsig zoo ntawm titanium-steel clad phaj.
1. Kev tsim qauv ntawm qhov zawj
Los ntawm cov qauv sib txawv groove tsim, ua ke nrog cov txheej txheem ntawm txheej txheej vuam, kev sib cuag ncaj qha ntawm molten steel puag txheej thiab titanium clad txheej yuav raug zam thaum lub sij hawm vuam txheej txheem, yog li ua tiav lub hom phiaj ntawm kev txo cov tiam ntawm brittle Ti-Fe intermetallic. compounds nyob rau hauv kev sib koom tes.
2. Tsim thiab ntxiv cov ntaub ntawv hloov pauv
Thaum cov molten titanium thiab hlau nyob rau hauv kev sib cuag ncaj qha thaum lub sij hawm vuam, tsis tsuas yog yuav brittle intermetallic tebchaw yuav tsim nyob rau hauv lub weld, tab sis ntau heev alloying cov tshuaj tiv thaiv kuj yuav ua rau lub dilution ntawm titanium clad txheej, yog li deteriorating cov kev ua tau zoo. sib koom. Ntxiv txheej hloov pauv ntawm ob yog ib txoj hauv kev zoo los daws cov teeb meem saum toj no.
3. Kev nkag mus vuam
Multi-layer multi-pass welding, nrog rau cov txheej txheem vuam ntxiv rau cov txheej txheem hloov pauv, thiab lwm yam, tuaj yeem txo cov khoom sib txuas ntawm intermetallic hauv kev sib koom ua ke thiab txhim kho kev ua haujlwm. Cov kev tshawb fawb kuj tau lees paub tias kev txo cov vuam cua sov cov tswv yim yuav txo tau qhov sib txuas ntawm intermetallic. kom muaj txiaj ntsig zoo. Piv nrog rau cov txheej txheem arc welding ib txwm muaj, lub zog loj nqaj vuam muaj peev xwm siv tau zoo hauv kev vuam ntawm titanium-steel clad daim hlau vim nws qhov zoo ntawm lub zog siab ceev thiab tsis tshua muaj vuam cua sov input. Kev tshawb fawb ntawm beam vuam tseem nyob rau hauv nws cov me nyuam mos.
Tam sim no, kev tshawb fawb thiab engineering daim ntawv thov ntawm titanium-steel composite phaj welding los ntawm kev sib txuas ntawm ntau qhov kev siv vuam tshuab nrog ntxiv txheej txheej hloov tau kuj paub tab. Txawm li cas los xij, cov txheej txheem ntau txheej txheej txheej vuam muaj qhov tsis zoo ntawm cov txheej txheem cumbersome thiab kev ua haujlwm qis, uas txwv nws txoj kev siv dav rau qee yam. Txawm hais tias lub zog siab ntom ntom thiab tsis tshua muaj cua sov ntawm lub zog vuam vuam, nws tau pom zoo nyob rau hauv kev txhim kho kev ua haujlwm vuam kev ua haujlwm ntawm cov vaj huam sib luag. Txawm li cas los xij, kev tshawb fawb tob thiab kev ua haujlwm tseem ceeb tseem ceeb hauv kev xaiv, tsim thiab ntxiv cov txheej txheem hloov pauv ntawm cov hlau txuas ntxiv txhawm rau txhim kho cov pob qij txha zoo, uas tseem yuav yog ib qho ntawm cov lus qhia tseem ceeb hauv daim teb no yav tom ntej. .
Nrog rau kev nce ntxiv hauv daim ntawv thov kev lag luam ntawm titanium steel clad daim hlau thiab kev txhim kho txuas ntxiv ntawm vuam tshuab, vuam tshuab yuav ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa engineering daim ntawv thov ntawm titanium steel clad daim hlau. Nyob rau tib lub sijhawm, kev sim thiab theoretical kev tshawb fawb ntawm kev vuam ntawm titanium-steel clad daim hlau tseem yuav muab kev taw qhia thiab siv rau kev vuam ntawm qhov nyuaj-rau-weld dissimilar hlau thiab lwm daim hlau clad.
