Dab tsi yog ntshiab tungsten electrode?

Ntshiab tungsten electrode yog ib qho hluav taws xob siv hauv tungsten inert gas welding (TIG), tseem hu ua roj tungsten arc vuam (GTAW). Ntshiab tungsten electrodes yog tsim los ntawm 99.5% ntshiab tungsten thiab feem ntau yog xim coded ntsuab. Lawv paub txog lawv lub peev xwm tiv taus qhov kub thiab txias thiab muab kev ua haujlwm ruaj khov arc.

Ntshiab tungsten electrodes feem ntau yog siv rau vuam cov ntaub ntawv uas yuav tsum tau ib tug tsis-oxidizing ib puag ncig, xws li txhuas thiab magnesium alloys. Txij li thaum lawv tsim ib tug tsom thiab meej arc, lawv kuj yog haum rau vuam cov ntaub ntawv thinner.

Ntshiab tungsten electrodes tsis pom zoo rau kev siv vuam uas xav tau ntau dua tam sim no lossis rau cov khoom siv vuam uas tsim cov txheej oxide tuab, vim tias lawv muaj kev cuam tshuam ntau dua rau kev sib kis thiab tuaj yeem ua rau arc drift.

Hauv cov ntsiab lus, ntshiab tungsten electrodes yog tsim tshwj xeeb rau TIG vuam daim ntawv thov qhov chaw uas tsis yog-oxidizing thiab meej arc tswj yog qhov tseem ceeb. Lawv yog cov zoo tagnrho rau welding aluminium, magnesium thiab lwm yam ntaub ntawv uas tsis yog-ferrous, ua rau lawv yog ib qho tseem ceeb ntawm kev lag luam vuam.

Dab tsi yog qhov muaj pes tsawg leeg ntawm tungsten electrode?

Tungsten electrodes siv hauv TIG vuam feem ntau yog tsim los ntawm cov feem ntau ntawm tungsten, nrog rau me me ntawm lwm cov ntsiab lus ntxiv los txhim kho lawv cov kev ua tau zoo. Feem ntau cov khoom ntawm tungsten electrodes muaj xws li:

1. Pure Tungsten Electrodes: Cov electrodes no yog ua los ntawm 99.5% ntshiab tungsten thiab feem ntau yog xim coded ntsuab. Lawv tsim nyog rau kev siv vuam uas xav tau qhov chaw tsis muaj oxidizing, xws li vuam aluminium thiab magnesium alloys.

2. Thoriated Tungsten Electrodes: Cov electrodes no muaj me me ntawm thorium oxide tov nrog tungsten (feem ntau 1-2%). Lawv feem ntau yog xim coded thiab muaj lub ntsis liab. Thorium electrodes paub txog lawv qhov zoo tshaj plaws arc pib thiab ruaj khov, ua rau lawv haum rau ntau yam kev siv vuam.

3. Ceramic tungsten electrode: Ceramic electrode muaj cerium oxide (feem ntau 1-2%) thiab tungsten. Lawv cov xim feem ntau yog txiv kab ntxwv. Ceramic electrodes muaj qhov zoo arc stability thiab haum rau ob qho tib si AC thiab DC vuam, ua rau lawv haum rau ntau yam kev siv vuam.

4. Rare earth tungsten electrode: Rare earth electrode muaj ib qho me me ntawm lanthanum oxide tov nrog tungsten (feem ntau 1-2%). Lawv cov xim feem ntau yog xiav. Lanthanum series vuam rods muaj qhov zoo arc pib zog thiab ruaj khov, thiab haum rau AC thiab DC vuam.

5. Zirconium tungsten electrode: Zirconium electrode muaj ib qho me me ntawm zirconium oxide tov nrog tungsten (feem ntau yog 0.8-1.2%). Lawv cov xim feem ntau yog xim av. Zirconium electrodes paub txog lawv lub peev xwm tiv thaiv kab mob thiab feem ntau siv rau AC vuam ntawm txhuas thiab magnesium alloys.

Txhua hom tungsten electrode muaj cov yam ntxwv tshwj xeeb uas ua rau nws tsim nyog rau kev siv vuam sib txawv. Qhov kev xaiv ntawm electrode muaj pes tsawg leeg yog nyob ntawm cov yam ntxwv xws li hom khoom siv welded, vuam tam sim no, thiab cov kev cai tshwj xeeb ntawm cov txheej txheem vuam.
