Titanium tub raj thiabtitanium clad steel tube ntawvnthuav dav sib koom ua cov txheej txheem thiab vuam cov txheej txheem siv phau ntawv tungsten argon arc vuam. Nws tseem raug pov thawj los ntawm kev tsim ua qhov kev xav ntawm kua dej ammonia tub yees tias titanium raj thiab titanium clad steel tube ntawv tuaj yeem tau txais cov hlau tsis muaj hlau ua kom zoo nyob rau hauv qhov kev xaiv ntawm kev tsim cov txheej txheem tsim nyog. Nyob rau tib lub sijhawm, nws yog kev tsim khoom ntawm titanium thiab titanium steel composite phaj hloov khoom siv kub. Sau tej kev ua tau los.
Cov txheej txheem ntsuas thiab vuam txheej txheem kev soj ntsuam Titanium yog cov khoom siv uas muaj peev xwm tsim tau zaj duab xis oxide ntom nrog oxygen ntawm chav sov thiab tswj cov siab ruaj khov thiab xeb. Cov oxide zaj duab xis ua los saum toj 540" C tsis yog ntom. Titanium reacts sai sai nrog oxygen, nitrogen, thiab hydrogen ntawm qhov kub, thiab nws yog qhov yooj yim los tsim cov tshuaj brittle, uas ua rau lub weldability tsis zoo.
Yog li no, txhawm rau xyuas kom lub vuam zoo ntawm cov raj titanium thiab cov titanium clad steel tube ntawv, peb pib los ntawm cov ntsiab lus ntawm cov ntaub ntawv thiab cov khoom tsim, thiab tau txais qee cov ntaub ntawv los ntawm cov txheej txheem sim thiab vuam txheej txheem kev tsim nyog. Titanium-steel composite tube ntawv thiab cov raj raj titanium tuav cov txheej txheem tsim khoom ntawm thawj nthuav thiab tom qab ntawd vuam. Txhawm rau kom ntseeg tau tias cov khoom zoo, peb tau ua cov kev sim nram qab no.
Cov txheej txheem sim ntawm tube daim ntawv thiab lub raj lis cov kev sib koom tes sib xyaw Cov txias txias sab nraud yuav tsum tau nthuav tawm ua ntej thiab tom qab ntawd ua vuam. Lub zog tau lees tias los ntawm kev sib koom tes nthuav dav, thiab lub vuam siv yog feem ntau siv rau kev sib khi. Txhawm rau kom ntseeg tau tias lub zog ntawm kev sib koom tes nthuav dav, peb nres cov txheej txheem sim ntawm kev sib koom tes sib txuas nruab nrab ntawm cov ntawv tub raj thiab cov raj raj. Tom qab lub raj xa khoom siv ua kev sim, peb tau sim nthuav dav cov kev sib koom tes zoo los ntawm ntsuas qhov ntsuas siab-tso tawm lub zog, thiab paub tseeb tias cov ntawv sib koom tes thiab cov sib koom tes sib koom tes thiab lwm cov txheej txheem sib txawv kom paub tseeb tias qhov nthuav tawm nyob hauv qhov ntau thiab ua tau raws li cov qauv tsim.
