Thaum nws los txog rau vuam titanium kav, tsuas muaj ib lo lus ntawm lub hauv paus: "kev tiv thaiv". Titanium, ntawm qhov kub thiab txias, yog "courtesan", tsis tshua muaj kev tshaib plab rau cov pa oxygen, nitrogen, hydrogen, thaum nws raug cua thaum lub sij hawm vuam, lub vuam yuav nkig, discolored, los yog tawg, thiab nws nto moo corrosion kuj yuav poob. Yog li ntawd, tag nrho peb cov kev npaj thiab kev khiav hauj lwm tig mus yuav ua li cas kom nws tag nrho huab cua- cais tawm ntawm tag nrho cov txheej txheem los ntawm cua sov, melting kom txias mus rau hauv qab 300 degrees Celsius.
Kev npajBua ntejWelding
Thawj yog kev ntxuav. Qhov no tsis yog ib qho yooj yim so. Tsawg kawg li ntawm 25 hli ntawm ob sab ntawm titanium yeeb nkab bevel, nrog rau ntawm qhov chaw ntawm vuam hlau, ib qho me ntsis roj, noo noo, plua plav lossis txawm tias tus ntiv tes yuav decompose rau hauv carbon, hydrogen, thiab oxygen ntawm qhov kub thiab txias, polluting lub vuam seam thiab ua rau porosity thiab tawg. Lub bevel yuav tsum tau sanded kom huv si nrog stainless hlau xaim txhuam tshwj xeeb uas tsim los rau titanium kom txog thaum nws nthuav tawm nws cov xim hlau. Tom qab ntawd ntxuav nrog cov kuab tshuaj tshwj xeeb xws li acetone, nco ntsoov tias koj yuav tsum tsis txhob siv cov kuab tshuaj uas muaj chlorine (xws li trichloroethylene), chloride ions tuaj yeem ua rau muaj kev ntxhov siab corrosion tawg, uas yog kev puas tsuaj. Tom qab ntxuav, nws yog qhov zoo tshaj rau hnav hnab looj tes, thiab nws yuav tsum tau welded tsis pub dhau 4 teev tom qab ntxuav, txwv tsis pub nws yuav tsum tau reprocessed.
Qhov thib ob yog kev tiv thaiv roj, uas yog tus ntsuj plig ntawm titanium vuam. Lub purity ntawm argon roj yuav tsum ncav cuag ntau tshaj 99.999%, thiab yuav tsum tsis muaj noo noo los yog impurities txhua. Nws tsis txaus los tiv thaiv pem hauv ntej weld pas dej ua ke nrog lub nozzle ntawm rab phom vuam. Koj yuav tsum tsim ib lub tshuab nqus tsev rau sab nraum qab ntawm lub vuam (hauv lub raj) thiab cais qhov chaw hauv lub raj nrog siab -cov ntaub ntawv kub los yog tshwj xeeb "dej- ntawv soluble" kom ntseeg tau tias cov roj argon puv thiab nyob hauv nws. Qhov tseem ceeb tshaj, titanium tseem yuav tsum tau muaj kev tiv thaiv thaum lub sij hawm tshaj tawm -welding theem. Cov xim ci ntsa iab ntawm qhov chaw weld yog qhov zoo saib, tab sis nws yog pov thawj ntawm kev tiv thaiv tsis ua haujlwm. Yog li ntawd, ib qho cuab yeej hu ua "tail tow" yuav tsum tau siv, uas ua raws li lub teeb zoo li lub kaus txav thiab txuas ntxiv tshuab argon ntawm cov vuam thiab cua sov- thaj chaw cuam tshuam uas nyuam qhuav khov tab sis tseem nyob rau qhov kub thiab txias kom txog thaum kub poob qis dua 300 degrees. Ua ntej welding, nco ntsoov ua qhov kev tiv thaiv kev tiv thaiv: qhov cua zoo, arc lub phaj xeem yam tsis tau sau cov xaim, thiab yaj lub vuam sib txuas. Yog hais tias qhov saum npoo ntawm qhov sib koom ua ke yog nyiaj -dawb li daim iav, zoo siab nrog rau, kev tiv thaiv nyob rau hauv qhov chaw. Yog tias nws tshwm daj, xiav lossis grey, tom qab ntawd koj yuav tsum kuaj xyuas koj cov pa roj, ntws thiab kev tiv thaiv cov cuab yeej sai sai, thiab koj yuav tsum tsis txhob pib vuam txoj cai kom txog thaum qhov teeb meem daws tau.
VuamProcess
Ua ntej arcing, yuav tsum muaj lub sijhawm ua ntej - qhov cua, kwv yees li 3 mus rau 5 vib nas this, txhawm rau hloov cov huab cua hauv qhov sib txuas, cov kav dej, thiab cov pa roj. Thaum vuam, siv qhov luv tshaj plaws arc (1 mus rau 2 hli), qhov ntev ntawm lub arc yog yooj yim rau do cua, thiab kev tiv thaiv cov nyhuv yuav phem dua. Thaum noj cov hlau, lub vuam hlau lub taub hau yuav tsum nyob twj ywm hauv qhov chaw tiv thaiv roj argon, thiab yuav tsum tsis txhob rub tawm thiab xa mus rau hauv, sai li sai tau thaum nws nkag mus thiab tawm, nws nqa cov cua nkag mus.
Kev tswj cov khoom siv hluav taws xob kuj tseem ceeb heev, tsis txhob siv tam sim no ntau dhau los txhawm rau txhawm rau hauv av vuam, nyob rau hauv qhov chaw ntawm kev ua kom muaj kev nkag mus, qhov ceev yog qhov tsim nyog sai dua, txo lub sij hawm nyob ntawm vuam thiab lub hauv paus hlau ntawm qhov kub thiab txias, thiab tiv thaiv cov nplej los ntawm kev loj hlob thicker.
Thaum vuam arc retraction, kev paub ntau dua. Nws tsis zoo li koj tam sim tsa koj rab phom thiab tua huab cua sai li sai tau thaum koj kaw lub arc. Lub vuam vuam yuav tsum nyob ntawm qhov taw tes arc ib ntus, thiab tib lub sijhawm lag luam cua, thiab txuas ntxiv tshuab argon roj kom txias cov liab siab -kub weld. Lub sijhawm no tuaj yeem siv sijhawm li 15 vib nas this mus rau ib nrab ib feeb kom txog thaum lub vuam hlau ua tiav nws cov xim liab thiab tsis kub nrog sab nraub qaum. Cov kauj ruam no yog kauj ruam kawg los xyuas kom meej qhov zoo ntawm cov vuam, thiab nws kuj yog qhov yooj yim tshaj rau tub nkeeg.
Tshaj tawm -WeldIkev soj ntsuam (Color)
Nyiaj dawb / ci nyiaj:zoo meej kev tiv thaiv, zoo tshaj plaws weld zoo.
Lub teeb daj / Golden daj:Muaj me ntsis oxidation, uas tej zaum yuav tau txais nyob rau hauv tej lub sij hawm undemanding, tab sis rau hnyav ua hauj lwm tej yam kev mob, qhov no twb yog ib tug ceeb toom.
Tsaus xiav / ntshav:Oxidation yog pom tseeb dua, cov yas thiab corrosion kuj ntawm weld tau txo, thiab feem ntau nws yog tsim nyog los txiav tawm lub re- vuam.
Tawm -dawb/grey-dub:Cov oxidation hnyav, nkig welds, thiab txawm tias hmoov tev tawm, yuav tsum tau muab tshem tawm tag thiab rov-welded.
Tag nrho cov nyob rau hauv tag nrho cov, vuam titanium kav tsis raws li nws kim heev li vuam carbon steel, nws yog zoo li ua ib tug precision sterile phais. Qhov nruj thiab ceev faj ntawm txhua kauj ruam yuav yog qhov kawg ntawm qhov ci ntsa iab, ntom ntom thiab muaj zog weld. Nws ntsuas tsis tau tsuas yog siv tshuab, tab sis kuj yog tus welder lub siab ntev, kev nkag siab ntawm lub luag haujlwm thiab kev nkag siab tob ntawm cov khoom siv.
