Argon arc welding, nws hom thiab cov yam ntxwv

Argon Vuam - ib yam ntawm cov hluav taws xob arc welding. Nws feature yog hais tias lub vuam txoj kev yuav siv sij hawm qhov chaw nyob rau hauv inert cov roj, uas tiv thaiv oxidation ntawm cov hlau.

Cov cheeb tsam uas yog tiav nyob rau hauv ib tug tiv thaiv cov roj, muaj cov nram qab no hais: lub electrode ntsis thiab cov muab tub lim cov ntaub ntawv uas sau tseg weld feem thiab tshav kub cuam tshuam cheeb tsam. Argon - nruab nrab inert roj uas tsis hnov mob nrog cov hlau thaum lub sij hawm vuam thiab yog noj los ntawm ib tug tshwj xeeb nozzle electrode teeb. Gas lub npe muab kev koom tes nyob rau hauv tus txheej txheem, thiab twb muaj npe no hom ntawm kev twb kev txuas qhov chaw.

Tig vuam cov khoom muaj xws li ib tug uas tsis yog-consumable electrode, uas feeb yog ua los ntawm tungsten. Qhov no refractory hlau muaj tag nrho cov uas yuav tsum tau zoo thiab cov yam ntxwv, ces nws yog feem ntau siv nyob rau hauv no hom ntawm welding.

Nyob rau hauv xws li ib tug cov ntaub ntawv muab tub lim cov ntaub ntawv uas nkag rau hauv daim ntawv ntawm hlau los yog pas nrig, uas thaum lub sij hawm tus txheej txheem yog tsis tseg raus hauv lub molten pas dej ua ke. Thaum lub sij hawm lub lag luam lub electrode yog muaj los ntawm ib tug tshwj xeeb bracket, uas yog mounted rau hauv lub nozzle, tsim los rau argon gas pub rau cov cheeb tsam nyob qhov twg lub argon-arc vuam yog nqa tawm. Khoom, ntsig txog, thiab yuav tsum tau withstand lub fais tam sim no ntws los ntawm cov electrodes, thiab thermal nyhuv los ntawm kev siv ntawm argon.

Txawm li cas los, tsis tsuas yog ua los ntawm tungsten electrodes. Lawv kuj yuav ua los ntawm stainless steel thiab txhuas. Nyob rau hauv no hais txog, argon arc vuam yog muab faib ua 2 hom:

1. Nrog consumable electrode.
2. Nrog uas tsis yog-consumable electrode.

Argon arc vuam yog ceev thiab tsis siv. Nrog tsis siv neeg vuam electrode yog tsuas yog siv dragged thiab los ntawm txhais tes vuam yuav tsum tau uas tsis yog-consumable electrode.

Cov hauj txheej txheem ntawm tig welding.

Vim hais tias cov inert gases tsis hnov mob nrog co, raws li zoo raws li lub fact tias lawv nyob rau nruab nrab 38% hnyav dua cov pa siv rau welding, argon yooj yim tshem cov huab cua nrog undesirable impurities ntawm lub vuam tsam. Qhov no txhob undesirable oxidation ntawm lub resulting weld, uas muaj nuj nqis tsub kom qhov zoo tshaj ntawm cov khoom thiab nws aesthetic qualities.

Los ntawm electrodes hluav taws xob tam sim no yog dhau ntawm welded qhov chaw. Ib txhij nrog cov pib ntawm zaj tam sim no cov khoom pib argon khiav los ntawm cov burner nozzle. Khoom txheej txheem sau nyob rau hauv lub cheeb tsam ntawm Vuam muab tub lim cov ntaub ntawv uas, uas yog melted los ntawm lub tshav kub hloov zuj zuj los ntawm dua tam sim no.

Txij li thaum argon tiv thaiv arcing, nws yog tsim nyog los siv ib tug tshwj xeeb ntaus ntawv hu ua ib qho oscillator. Qhov no ntaus ntawv muab ib tug txhim khu kev qha tiv cav tseb ntawm lub arc los ntawm txoj kev high-zaus pulses, thiab kuj yuav tsub lub stabilization ntawm arc paug thaum lub sij hawm ntawm polarity reversal.

Qhov zoo muaj los ntawm argon arc welding, yog:

1. Efficiency.
2. Lub me me thickness ntawm lub weld.
3. Cov tau Vuam qhov chaw tsis muaj muab tub lim cov ntaub ntawv uas.
