Argon arc vuam yog hom hluav taws xob arc vuam. Nws peculiarity nyob rau hauv qhov tseeb hais tias cov txheej txheem vuam yuav siv sij hawm qhov chaw nyob rau hauv ib tug tiv thaiv roj, uas tiv thaiv cov hlau los ntawm oxidizing.
Thaj chaw uas tau kho nrog cov roj tiv thaiv muaj xws li cov hauv qab no: qhov kawg ntawm cov khoom siv hluav taws xob thiab cov khoom muab tub lim, ib feem ntawm cov seam thiab thaj chaw muaj kev kub ntxhov. Argon yog ib qho nruab nrab inert roj uas tsis cuam tshuam nrog cov hlau thaum lub sij hawm vuam thiab muab los ntawm ib tug tshwj xeeb nozzle ntawm lub teeb tuav. Los ntawm lub npe ntawm cov roj uas koom nrog hauv cov txheej txheem thev naus laus zis, hom kev sib txuas ntawm cov khoom no tau muaj npe.
TIG vuam cov cuab yeej suav nrog cov khoom siv hluav taws xob tsis siv, uas yog ib txwm ua los ntawm tungsten. Cov hlau refractory no muaj tag nrho cov kev xav tau thiab cov yam ntxwv, yog li nws feem ntau siv rau hauv hom vuam no.
Nyob rau hauv cov ntaub ntawv no, cov khoom muab tub lim yog muab nyob rau hauv daim ntawv ntawm ib tug hlau los yog pas nrig, uas thaum lub sij hawm cov txheej txheem thev naus laus zis yog ib ntus raus rau hauv lub pas dej ua ke. Thaum lub sijhawm ua haujlwm, lub tshuab electrode yog tuav los ntawm tus tuav tshwj xeeb, uas tau nruab rau hauv lub nozzle npaj rau kev muab khoomargon gas mus rau thaj chaw uas argon arc vuam yog nqa tawm. Cov cuab yeej siv, raws li, yuav tsum tau tiv thaiv ob qho tib si hluav taws xob tam sim no dhau los ntawm cov electrodes thiab thermal los ntawm kev siv argon.
Txawm li cas los xij, electrodes tsis yog tsim los ntawm tungsten nkaus xwb. Lawv tuaj yeem ua los ntawm stainless hlau thiab aluminium. Hauv qhov no, argon arc vuam tau muab faib ua 2 hom:
- Fusible electrode.
- Nrog tsis siv hluav taws xob.
Argon arc vuam tuaj yeem yog phau ntawv thiab tsis siv neeg. Hauv kev vuam tsis siv neeg, tsuas yog siv cov hlau electrode xwb, thiab kev tuav vuam tuaj yeem ua tiav nrog cov khoom siv hluav taws xob tsis siv.
Technological txheej txheem ntawm argon arc vuam.
Vim tias cov pa roj tsis zoo tsis cuam tshuam nrog cov hlau, thiab vim tias lawv nyob nruab nrab 38% hnyav dua li cov pa siv hauv vuam, argon yuav yooj yim tshem tawm huab cua nrog tsis xav tau impurities los ntawm qhov chaw vuam. Qhov no tsis txhob plam oxidation ntawm qhov tshwm sim seam, uas txhim kho cov khoom zoo thiab nws cov khoom zoo nkauj.
Hluav taws xob tam sim no dhau los ntawm cov electrodes mus rau qhov chaw yuav tsum tau welded. Ib txhij nrog qhov pib ntawm kev nkag mus ntawm tam sim no los ntawm ib feem, cov khoom siv ntawm argon los ntawm lub qhov cub hluav taws xob pib. Cov txheej txheem ntawm kev nkag mus rau hauv qhov chaw vuam ntawm cov khoom muab tub lim yog pib, uas melts nyob rau hauv qhov kev txiav txim ntawm cov cua sov tso tawm los ntawm txoj kev tam sim no.
Vim tias ib puag ncig argon tsis tso cai rau arcing,Koj yuav tsum tau siv cov cuab yeej tshwj xeeb hu ua oscillator. Cov cuab yeej no muab kev ruaj ntseg arc ignition nrog high-frequency pulses, thiab kuj ua rau kom lub stabilization ntawm arc tawm thaum lub sij hawm ntawm polarity reversal.
Qhov zoo ntawm TIG vuam yog:
- Efficiency.
- weld thickness nyias.
- Muaj peev xwm ntawm qhov vuam yam tsis muaj cov khoom muab tub lim.
