Kho welding rau tawg ntawmcondenser titanium yeeb nkab:
Qhov tseem ceeb yog tshem tawm qhov tawg mus rau hauv paus. cov kab nrib pleb yuav tsum tau muab tshem tawm tag nrho los ntawm kev siv lub taub hau polisher thiab reamer lub taub hau ua ntej tom qab lawv pom, txwv tsis pub cov kab nrib pleb tom qab kho vuam yuav maj mam txuas mus rau qhov tsis txaus tom qab ob peb teev, ua rau cov kab nrib pleb tshiab.PT kev tshuaj xyuas yog nqa tawm ntawm qhov tawg. thaj chaw tom qab kev khawb thiab kho, thiab kev kho vuam tuaj yeem ua tiav tsuas yog tom qab nws tau raug tshem tawm tag nrho: thaj tsam tawg yuav tsum tau ntxuav nrog ua ntej kho vuam; Ntxiv welding hlau rau lub sijhawm lag luam ntawm kev kho vuam. Tus yuam sij rau kev txhim kho vuam vuam yog tswj qhov kub thiab txias, nres oxidation thiab overheating ntawm titanium yeeb nkab, xyuas PT tom qab ua tiav qhov txias ntawm cov vuam sib txuas, thiab xyuas PT dua tom qab 24 teev los txiav txim seb puas muaj qhov tawg qeeb.
Kho welding ntawm cua qhov:
Pore tsim yog tsuas yog tshwm sim los ntawm impurities ntawm lubcondenser titanium yeeb nkabthiab lub cev daim ntawv. Kev saib xyuas tseem ceeb yuav tsum tau them rau cov ntawv tswj cov raj ua ntej welding kom lub cim ntawm lub pore tuaj yeem zam tau zoo. welding hlau feem ntau tsis tas yuav tsum tau kho cov cua qhov. Kev ua haujlwm ruaj khov yog xav tau thaum kho vuam. Lub ntsiab lus ntawm tungsten yog ncaj qha mus rau lub arcing nyob rau hauv lub pore cheeb tsam. Lub arc nres tam sim ntawd tom qab lub pore melts. Lub sij hawm attenuation thaum lub sij hawm arc nres yuav tsum ntau tshaj 4S thiab lub arc nres / T.tsis txhob tshem tawm cov argon arc tam sim ntawd. Siv argon kom txias qhov sib koom ua ke rau ob peb feeb ua ntej tshem tawm argon arc. qhov chaw tom qab kho vuam yuav tsum ci dawb nrog hlau gloss. Yog tias cov xim dhau los ua xiav lossis nyiaj grey, nws qhia tau tias qhov kub thiab txias siab dhau thaum kho vuam thiab cov kab nrib pleb yooj yim pom thaum lub sij hawm tshuaj xyuas PT.
Kev kho ntawm weld beading thiab tsis tiav fusion defects:
Nws yog tsuas yog tshwm sim los ntawm xoob expansion ntawm lubcondenser titanium yeeb nkablos yog tsis txaus coaxiality ntawm lub vuam tshuab, thiab qhov sib txawv ntawm cov phom vuam los ntawm cov kab nruab nrab ntawm lub titanium raj. qhov chaw ntawm vuam qhov mob thiab tsis tiav fusion defects yog feem ntau sib sib zog nqus. Qee cov hlaws hlaws yog 3.5 hli deb ntawm cov yeeb nkab orifice, yog li kev kho vuam qhov chaw nyuaj. Thiab vim hais tias cov yeeb nkab titanium nyias nyias, nws yooj yim rau hlawv cov yeeb nkab titanium thaum kho vuam, ua rau qhov tshwm sim ntawm kev kho ntau dua, kev kho vuam nyuaj dua. Ua ntej kho vuam ntawm qhov tsis tiav fusion defects ntawm weld beading, weld beading yuav tsum tau muab tshem tawm nrog cov cemented carbide rotary cov ntaub ntawv, thiab tom qab ntawd cov yeeb nkab yuav tsum tau nthuav dav dua nrog cov yeeb nkab expander, thiab tom qab ntawd kev kho vuam yuav tsum tau nqa tawm tom qab ntxuav nrog. ketone lub cev. Qhov kev kho welding no yuav tsum muaj kev siv vuam siv siab rau tus neeg teb xov tooj. Hauv kev ua haujlwm, peb yuav tsum tau nkag siab tag nrho cov haujlwm tseem ceeb ntawm "kev ruaj ntseg, qhov tseeb, thiab kev ua siab phem", uas yog, kev ua haujlwm yuav tsum ruaj khov, kev noj cov hlau yuav tsum yog qhov tseeb, thiab kev txiav txim siab yuav tsum txiav txim siab.
Thaum kho vuam, tus neeg teb xov tooj yuav tsum tuav rab phom welding thiab lean ntawm lub raj phaj kom tsis txhob muaj kev ruaj ntseg ntawm rab phom vuam thiab arc hlawv ntawm lwm qhov ntawm lub titanium raj. Thaum lub sij hawm xaim noj, txhua qhov poob ntawm cov vuam hlau yuav tsum raug xa mus rau qhov tsis xws luag, thiab txoj hauj lwm yuav tsum tau noj yuav tsum tau txiav txim siab yam tsis muaj hesitation, thiaj li tiv thaiv oxidation los ntawm kub heev. qee qhov tsis xws luag nyob deb ntawm qhov chaw ntawm lub raj xaim, yog li nws nyuaj rau pub hlau thaum kho vuam. Txhawm rau tiv thaiv qhov tsis xws luag los ntawm qhov loj thiab loj dua vim qhov kev pub mis tsis tu ncua ntawm cov kab, ib qho kev poob ntawm cov vuam hlau tuaj yeem yaj ntawm ntug ntawm qhov tsis xws luag ua ntej kho qhov vuam.
