Argon arc vuam yog hom hluav taws xob arc vuam. Qhov peculiarity ntawm cov txheej txheem thev naus laus zis yog raws li hauv qab no: argon arc vuam tshuab tsim ib qho chaw tiv thaiv roj. Qhov no tiv thaiv tau oxidation ntawm cov ntaub ntawv welded.
TIG vuam tshuab tsim tshwj xeeb hauv thaj chaw vuam, uas cov khoom yuav tsum tau welded, electrodes, muab tub lim, seam cheeb tsam thiab ib feem me me ntawm cov seam nyob. Tag nrho cov ntsiab lus no yog ib puag ncig los ntawm cov hlau tsis muaj zog inert hu ua argon. Gas yog muab los ntawm ib tug tshwj xeeb channel - lub nozzle - nyob rau hauv lub tuav ntawm ib tug hluav taws xob burner.
Lub npe ntawm tag nrho cov txheej txheem thev naus laus zis los ntawm qhov tshwj xeeb no - cov pa roj tshwj xeeb inert.
TIG vuam tshuab muaj cov hauv qab no tseem ceeb thiab tsis muaj kev cuam tshuam cov qauv: cov khoom siv hluav taws xob uas tsis yog siv tau los ntawm cov khoom siv refractory thiab cov khoom muab tub lim uas yaj yooj yim heev thiab tso cai rau ntau qhov chaw los koom ua ke. Cov khoom siv electrode feem ntau yog tungsten, txij li nwsmuaj txhua yam uas yuav tsum tau muaj thiab cov yam ntxwv zoo heev rau cov txheej txheem no.
Cov khoom siv muab tub lim, dhau los, tuaj yeem ua los ntawm ntau yam hlau, uas tau pub rau hauv qhov chaw vuam hlau nyob rau hauv daim ntawv ntawm daim kab xev los yog hu ua pas nrig. Lub argon arc vuam tshuab raws sij hawm immerses cov khoom muab tub lim rau hauv lub pas dej weld nyob rau hauv tus nqi tsim nyog rau cov txheej txheem no.
Raws li tau hais dhau los, muaj lub taub hau ib sab ntawm lub tshuab hluav taws xob, sab hauv uas muaj lub thawv tshwj xeeb rau lub tshuab hluav taws xob tau teeb tsa, nyob rau tib qhov chaw uas muaj roj nkag. Qhov no ua kom ntseeg tau tias qhov chaw nruab nrab ntawm cov huab cua yog qhov tseeb nyob rau hauv qhov chaw ntawm qhov vuam tau ua tiav. Yog li ntawd, qhov tshwm sim uas cov pa oxygen ntxiv yuav ua rau oxidation ntawm cov hlau yog txo qis heev. Hauv qhov no, argon arc vuam tshuab yuav tsum muaj kev tiv thaiv zoo rau cov teebmeem ntawm hluav taws xob tam sim no thiab thermal tawg. Qhov ntsuas no ua lub luag haujlwm tseem ceeb thaum xaiv cov cuab yeej siv rau ib qho txheej txheem vuam txheej txheem.
Kev faib cov khoom siv vuam:
TIG vuam tshuab tuaj yeem nruab nrog ob hom electrodes:
- Tsis yaj. Tungsten ib txwm siv rau hom electrode.
- Fusible. Rau cov laj thawj no, qhov ua tau zoo tshaj plaws yog siv cov txhuas thiab stainless hlau.
vuamib chav tsev ntawm hom no tuaj yeem nthuav tawm hauv phau ntawv thiab tsis siv neeg tua. Txawm li cas los xij, txawm tias qhov sib txawv me me no muaj qee qhov kev hloov pauv. Piv txwv li, nyob rau hauv lub tshuab welding tsis siv neeg, nws yog kev cai siv tsuas yog electrode hlau, uas nkag mus rau hauv cheeb tsam uas yuav tsum tau welded ntawm qhov yuav tsum tau ceev.
Qhov zoo ntawm txoj kev no yog suav tias yog qhov tuab me me ntawm qhov ua tau zoo, kev ua haujlwm siab thiab kev ntseeg siab ntawm cov txheej txheem.
