Nyob rau niaj hnub no txoj kev loj hlob sai ntawm kev lag luam aluminium, xaiv cov khoom siv vuam zoo tau dhau los ua qhov tseem ceeb. Cov kev taw qhia tsis ntev los no ntawm cov thev naus laus zis tshiab tau teeb tsa los hloov kev lag luam - kev siv cov xim tshwj xeeb tungsten electrodes los txhim kho qhov zoo thiab ua haujlwm ntawm txhuas vuam. Qhov kev tshawb pom no tsis yog tsuas yog qhia txog kev nce hauv kev tsim khoom, tab sis kuj yog qhov tseem ceeb hauv kev siv tshuab vuam.

Tungsten electrodes, raws li cov khoom siv tseem ceeb rau tungsten arc vuam (TIG), ib txwm yog ib feem tseem ceeb ntawm kev lag luam vuam. Cov xim sib txawv ntawm tungsten electrodes qhia txog cov ntsiab lus sib txawv thiab cov peev txheej ntawm daim ntawv thov, thaum rau txhuas vuam, cov kws tshaj lij pom zoo kom siv ntsuab tungsten electrodes. Ntsuab tungsten electrodes muaj cov ntshiab tungsten thiab yog qhov zoo tagnrho rau cov vuam tam sim no ntawm aluminium thiab aluminium alloys vim lawv cov hluav taws xob zoo heev thiab kub tsis kam.

Kev siv ntsuab tungsten electrodes muab qhov chaw ruaj khov dua thaum lub sij hawm vuam txheej txheem thiab txo cov vuam tsis xws li porosity thiab inclusions, yog li kev txhim kho cov cuab yeej cuab tam thiab cov tsos ntawm cov pob qij txha. Tsis tas li ntawd, kev ruaj ntseg ntawm cov ntshiab tungsten electrodes ntawm qhov kub thiab txias yog superior rau lwm hom tungsten electrodes, uas ua rau nws tshwj xeeb tshaj yog zoo thaum ua hauj lwm nrog nyias aluminium daim hlau los yog ua hauj lwm welding ilv.

Raws li cov kws tshaj lij kev lag luam, txoj hauv kev tshiab ntawm kev siv ntsuab tungsten electrodes yuav ua rau muaj txiaj ntsig zoo thiab cov txiaj ntsig zoo rau kev lag luam txhuas. Cov thev naus laus zis tsis yog tsuas yog txo cov khoom pov tseg hauv cov txheej txheem tsim khoom, tab sis kuj ua rau lub sijhawm ua haujlwm luv thiab txhim kho tag nrho cov txiaj ntsig ntawm cov kab ntau lawm.

Nrog rau kev txhawb nqa ntawm ntsuab tungsten electrode thev naus laus zis, nws xav tias yuav tsav lub txhuas ua kev lag luam mus rau kev coj ua tau zoo dua thiab ib puag ncig zoo. Daim ntawv thov ntawm cov thev naus laus zis tshiab no tsis yog tsuas yog siv rau txhuas vuam, tab sis kuj tseem xav tau txuas ntxiv mus rau kev ua cov khoom siv hlau yav tom ntej, coj cov kev hloov pauv rau tag nrho cov kev lag luam tsim khoom.

FORGED, ua ib lub tuam txhab ua lag luam hauv kev lag luam, twb tau pib siv cov thev naus laus zis tshiab no hauv nws cov kab ntau lawm, thiab tos ntsoov yuav tshawb nrhiav ntau txoj hauv kev ua haujlwm nrog cov npoj yaig hauv kev lag luam los koom ua ke txhawb kev tsim kho tshiab thiab kev loj hlob ntawm kev lag luam.
