Titanium welded tubesyog dav siv nyob rau hauv aerospace, tshuaj ua, marine, thiab kev kho mob industries vim lawv zoo heev corrosion kuj, lub teeb yuag zog, thiab siab zog. Ua tau siab - zoo titanium welded raj yuav tsum tau tshwj xeeb txheej txheem thiab nruj zoo tswj. Ntawm no yog cov lus qhia dav dav ntawm cov txheej txheem tsim khoom thiab cov ntsiab lus tseem ceeb
1. Kev npaj raw khoom
Titanium Coil los yog Sawb:
High-purity titanium (feem ntau qib xws li Gr1, Gr2, Gr5) yog muab los ua cov kauj lossis cov strips. Cov khoom siv yuav tsum huv, tiaj tus, thiab tsis muaj qhov tsis xws luag.
Kev Tu Nto:
Ua ntej tsim, lub sawb yog huv si kom tshem tawm cov roj, av, thiab oxidation. Qhov no yog qhov tseem ceeb vim tias titanium muaj qhov ua haujlwm siab ntawm qhov kub thiab txias.
2. Tube txoj kev
Roll forming:
Cov titanium uas ntxuav tau yog pub los ntawm cov chais, maj mam ua rau hauv ib puag ncig (lossis lwm yam xav tau profile) raj.
Ntug Kev Npaj:
Cov npoo ntawm cov sawb yog precisely ua raws li kom muaj ib tug uniform, nruj seam rau vuam.
3. Vuam
Vuam txoj kev:
Txoj kev vuam ntau tshaj plaws rau titanium raj yogGTAW (Gas Tungsten Arc Vuam, tseem hu ua TIG vuam).
Qee zaum,Laser Vuamlos yogPlasma Arc Vuamyog siv rau siab - ceev automated kab.
Shielding Gas:
High -purity argon rojyog siv los tiv thaiv ob lub pas dej da dej thiab sab nrauv ntawm cov pa oxygen, nitrogen, thiab hydrogen. Titanium reacts yooj yim nrog cov pa roj carbon monoxide ntawm qhov kub thiab txias, ua rau embrittlement.
Sab hauv thiab sab nraud shielding:
Rau nyias- cov hlab phab ntsa, tshwj xeeb yog muab rau kev tiv thaiv sab hauv lub raj ("rov qab purging") kom tsis txhob muaj kab mob.
4. Weld Seam Kev Kho Mob
Kev tshuaj xyuas:
Weld seam yog kuaj pom pom thiab nrogtsis yog -kev kuaj kev puas tsuajtxoj kev (xws li X-ray, ultrasonic, lossis eddy tam sim no kuaj) kom paub tseeb tias tsis muaj kab nrib pleb, porosity, los yog inclusions.
Kev kho cua sov (yog tias xav tau):
Qee cov hlab ntsha tuaj yeem raug kev ntxhov siab los yog annealing los txhim kho ductility thiab tshem tawm cov kev ntxhov siab uas seem ntawm vuam.
5. Sizing thiab Straightening
Lub raj dhau los ntawm kev sib txuas ntxiv kom ua tiavmeej qhov ntevthiabroundness.
Straightening tshuabxyuas kom lub raj yog zoo kawg nkaus ncaj.
6. Txiav thiab ua tiav
Tubes yogtxiav rau qhov ntevsiv cov tshuab txiav tsis siv neeg.
Deburring thiab xaus -ua tiavcov txheej txheem tshem tawm cov npoo ntse thiab npaj lub raj rau kev siv ntxiv.
7. Kev soj ntsuam zaum kawg thiab kev tswj xyuas zoo
Mechanical Testing:
Yield zog, tensile lub zog, thiab elongation raug soj ntsuam kom ua tau raws li cov qauv.
Dimensional soj ntsuam:
Phab ntsa thickness, txoj kab uas hla, thiab ntev yog ntsuas precisely.
Nto Zoo:
Tubes raug tshuaj xyuas qhov tsis xws luag, discoloration, los yog paug.
Cov ntaub ntawv:
Ua kom tiav traceability cov ntaub ntawv raug khaws cia rau txhua pawg.

Cov ntsiab lus tseem ceeb
Kev tiv thaiv los ntawm huab cua yog qhov tseem ceebthoob plaws hauv cov txheej txheem vuam los tiv thaiv embrittlement.
Kev huv thiab precisionntawm txhua theem kom ntseeg tau tias muaj kev tiv thaiv corrosion siab thiab cov khoom siv kho tshuab ntawm cov raj tiav.
Cov qauv nruj nruj(ASTM, AMS, ISO, thiab lwm yam) tau ua raws li kev lag luam thiab kev siv dav hlau.
Xaus
Kev tsim cov titanium welded raj yog cov txheej txheem sophisticated uas xav tau cov thev naus laus zis siab, cov neeg ua haujlwm txawj, thiab kev tswj xyuas kom zoo.
Kev tiv thaiv zoo thaum vuam, ua tib zoo tuav raw khoom, thiab kev tshuaj xyuas kom zoo yog qhov tseem ceeb los xyuas kom cov raj ua tau raws li qhov xav tau ntawm kev ua haujlwm siab -.
