Kev ceev faj rau refill vuam Gr12 titanium alloy yeeb nkab

General titanium tube manufacturers refill welding Gr12 titanium raj ib puag ncig tsis tuaj yeem muaj cua ntws, txwv tsis pub zoo ib yam li hauv lub thawv vuam hauv cov refill welding. Txawm li cas los xij, yuav tsum tau them nyiaj tshwj xeeb:
(1) thaj tsam ntawm thaj chaw vuam tsis tuaj yeem loj dhau, qhov ntws ntawm nitrogen hauv cov txheej txheem ntawm thaj vuam yuav tsum loj dua, thiab tsis tuaj yeem nres hauv nruab nrab ntawm cov pa roj;
(2) Tom qab thaj chaw vuam, yuav tsum txuas ntxiv kom dhau kev tiv thaiv nitrogen, kom txog thaum thaj av txias;
(3) Rau qee qhov tshwj xeeb castings, xws li complex nyias-walled castings, txhawm rau tiv thaiv oxidation ntawm sab nraub qaum ntawm thaj chaw vuam, koj tuaj yeem tshuab argon rau sab nraub qaum kom txog thaum lub casting txias;
(4) Kev xav tau ntawm thaj chaw vuam cov neeg ua haujlwm nrog cov txheej txheem siab.

Txhawm rau kom tau txais cov khoom zoo titanium raj castings rau thaj vuam, cov ntsiab lus hauv qab no yuav tsum tau muab sau tseg hauv cov txheej txheem ntawm thaj vuam:
(1) Qhov saum npoo ntawm thaj vuam castings yuav tsum huv si thiab qhuav, cov castings tsis raug tso cai los ntawm tes ncaj qha ua ntej thauj khoom rau hauv lub thawv vuam.

(2) Nyob rau hauv tus txheej txheem ntawm refill vuam titanium raj los tiv thaiv tungsten electrode thiab refill weldments luv luv-circuit, ua rau tungsten electrode puas, ua rau tungsten inclusions nyob rau hauv lub welded pob qij txha.
(3) Thaum thaj tsam thiab qhov tob ntawm thaj chaw vuam yog qhov loj, yuav tsum tau muab faib ua ob peb zaug nyob deb txheej vuam, thiab tos kom txog thaum txheej txheej vuam txheej dhau los ua kom txias tag ua ntej txheej tom ntej ntawm vuam, tsis tso cai kiag li. rau - weld rau hauv, txhawm rau tiv thaiv deformation ntawm casting.
(4) nyob rau hauv qhov muab tub lim yuav luag dhau, yuav tsum maj mam txo qhov tam sim no, txo qhov melting tsam. Yog li ntawd, nws raug nquahu kom siv cov khoom siv tam sim no los tiv thaiv cov arc tawg, ua rau tawg.
(5) Tom qab qhov kawg ntawm refill welding yuav tsum tau tso cai kom txias cov castings nyob rau hauv lub thawv rau ib lub sij hawm ntawm lub sij hawm ua ntej qhib lub thawv kom tshem tawm cov castings, nyob rau hauv thiaj li yuav tiv thaiv kom txhob kub ceev ntawm cov castings weld cheeb tsam tawg los yog deformation; qhov ntev ntawm lub sij hawm txias nyob ntawm phab ntsa thickness ntawm cov castings, feem ntau yog nyob rau hauv lub 15-30 hli.
(6) titanium tube castings tom qab ntxiv vuam, yuav tsum tau ceev nrooj annealed lossis kub isostatic siab, yuav tsum tsis txhob muab tso rau ntev heev, feem ntau tsis pub tshaj 5 hnub.
(7) Tus naj npawb ntawm patch welding yuav tsum tsis txhob tshaj cov kev cai ntawm cov ntaub ntawv tseem ceeb.
