Titanium alloys yog siv dav hauv aerospace, kev kho mob, thiab siab -kev ua haujlwm engineering vim lawv lub zog siab- rau - qhov hnyav piv, superior corrosion kuj, thiab siab - kub kam rau ua. Txawm li cas los xij, cov khoom tshwj xeeb no kuj ua rau titanium alloys nyuaj rau vuam siv cov txheej txheem ib txwm muaj. Laser vuam tshuab muab cov kev daws teeb meem meej thiab muaj txiaj ntsig los kov yeej cov kev cov nyom no.
Kev sib tw hauv Vuam Titanium Alloys
Thaum titanium nthuav tawm qhov zoo ntawm qhov kev sib txuas, nws cov khoom siv tshuaj muaj cov kev ua haujlwm sib txawv:
- High Chemical Reactivity:Thaum kub siab, titanium yog reactive heev nrog gases xws li oxygen, nitrogen, thiab hydrogen.
- Embrittlement thiab Defects:Cov txheej txheem ib txwm muaj xws li TIG (GTAW) lossis plasma arc vuam feem ntau qhia txog kev sib kis ntawm huab cua, ua rau kev sib koom ua ke, porosity, micro- tawg, thiab txo cov cuab yeej siv zog piv rau cov khoom siv hauv paus.
Cov txiaj ntsig tseem ceeb ntawm Laser Vuam rau Titanium
Laser welding daws ntau yam kev txwv ntawm cov txheej txheem arc ib txwm los ntawm ntau qhov zoo:
- Yam tsawg kawg nkaus Thaum tshav kub kub input & Txo Distortion:Lub teeb laser tsom teeb ua rau lub zog loj ntom ntom, ua rau muaj cua sov nqaim- cuam tshuam thaj chaw (HAZ) thiab tsawg kawg thermal deformation.
- Enhanced Joint Integrity:Kev tswj xyuas kom zoo laser vuam yields siab - cov pob qij txha muaj zog nrog zoo heev ductility thiab qaug zog tiv thaiv, txawm rau siab - kub titanium qib.
- Eco-Tus phooj ywg thiab huv:Cov txheej txheem yog huv, hu rau -dawb, thiab yooj yim automated rau repeatable siab -precision ntau lawm.
Cov kev coj ua zoo tshaj plaws rau kev ua tiav Laser Vuam
Txhawm rau kom ntseeg tau siab -zoo, tsis raug-dawb laser welds ntawm titanium Cheebtsam:
- Tooling & Fixturing:Ruaj ntseg clamp cov khoom siv kev cai fixtures kom nruj tolerances thiab txo qhov sib koom ua ke.
- Inert Gas Shielding:Siv txuas ntxiv, siab -purity argon gas shielding (sab saum toj, trailing, thiab rov qab roj) los tiv thaiv oxidation kom txog thaum lub weld txias hauv qab ~ 400℃.
- Kev soj ntsuam zoo ntawm Weld Xim:Ntsuam xyuas kev tiv thaiv kev ua tau zoo los ntawm kev soj ntsuam cov xim xim ntawm qhov chaw vuam - vuam:
· Nyiaj / Bright Straw:Kev tiv thaiv zoo heev (tsis muaj teeb meem oxidation).
· Xiav / Ntshav:Nruab nrab oxidation (tej zaum yuav tsum tau kho cov txheej txheem).
· Grey/White hmoov:Kev kis mob hnyav (weld embrittlement).
Raws li cov nqi tsim khoom txo qis thiab thev naus laus zis nce ntxiv, titanium alloys tau nthuav dav tshaj qhov tshwj xeeb aerospace thiab kev siv kho mob rau hauv kev lag luam kev lag luam.High -precision fiber ntau laser vuam systemyuav txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ntseeg siab, tsim kom muaj peev xwm ntawm cov khoom siv titanium thoob ntiaj teb.
