Tig-vuam: daim ntawv thov nta

Argon vuam tig (T ungsten kuv nert G li ), los yog uas tsis yog-consumable electrode vuam - thaum illuminated arc ntawm tungsten electrode thiab cov welded qhov chaw. Yog li, nyob rau hauv lub arc kis tshwm sim molten hlau hloov mus rau lwm. Qhov no tswj lub hlawv arcing thiab ho ua rau kom nws stability. Tsis tas li ntawd, tig-vuam los txo evaporation losses, excludes tau spatter thiab tas cov roj los ntawm tej yam uas cov arc kem nyob rau hauv molten hlau. Raws li ib tug tsim nyog tau, qhov weld zoo yog tsa mus rau ib tug tshiab, ntau sophisticated theem.

Tig-vuam yog nrog AC los yog DC, thiab, nyob rau hauv cov ntaub ntawv ntawm lub caij nyoog kawg no yog tsuas yog siv ncaj qha polarity, uas yog, thaum lub davhlau ya nyob twg "plus" plug welded qhov chaw, thiab mus rau lub davhlau ya nyob twg "ib tug rho tawm" - ib tug uas tsis yog-consumable electrode. Qhov yuav tsum tau mus cuag nyob rau hauv no txoj kev vim lub fact tias yog hais tias lub interchange davhlau ya nyob twg, qhov yuav tshwm ntawm overheating zoo nkaus li tungsten refractory hlau, thiab thiaj li nws kuj dauv ho. Nyob rau hauv tas li ntawd, tej zaum nws yuav ua rau chipping los yog melting ntawm lub electrode, uas ua rau kev tsis pom nrias tsis xws luag ntawm lub weld.

Tig vuam implies lub nram qab no loj hais rau tsob nroj tsim: ib qhov chaw ntawm AC los yog DC, arc stabilizer, ib tug oscillator, ib tug tam sim no tus nqi kho ntaus ntawv, tam sim no muaj mem tes generator, ib tug roj solenoid valve, thiab ib tug ntaus ntawv rau suppressing tam sim no Cheebtsam.

Tig-vuam yog lub feem ntau universal hom hlau compound, txij li thaum nws tso cai rau weld ntaub ntawv sib txawv nyob rau hauv txhua txoj hauj lwm nyob rau hauv qhov chaw.

High vuam txoj kev qhov chaw yog tiav los ntawm lub fact tias nws yog npaum hawm me ntsis ntxiv dua lwm yam ntawm welding. Nyob rau hauv no hais txog, tig-vuam yog tsuas yog siv thaum lub zoo cov yam ntxwv ntawm cov tau weld yog decisive tseem ceeb.

Lub qhov txawv feature ntawm no hom ntawm vuam yog qhov tseeb hais tias cov ntshiab argon yog siv los txuas kiag li tej ntaub ntawv, thaum lub seem hom Vuam roj yuav tsum tau xaiv nyob rau hauv raws li cov welded hlau.

Tig-vuam yog ib tug theej nyuab thiab laborious txheej txheem. Yog li ntawd, rau lub rooj sib tham yog yuav tsum tau los ntawm txaus kawm welder. Cov hauj txheej txheem yuav tsum los ntawm nws ib tug txaus dexterity, txij li thaum ib tug tes yog tsim nyog los muab txaus thiab raws sij hawm mov ntawm muab tub lim ntaub, thaum nyob rau hauv lwm cov tes yuav ua tau lub Vuam teeb.

Thaum xaiv ib tug vuam siv lub tshuab ntawm no zoo yuav tsum tau ua los ntawm cov nram qab no xav txog kev teem:

1. Nws yog tsim nyog los mus txiav txim lub hwj huam mov muaj peev xwm ntawm lub vuam siv lub tshuab.

2. Ua tsaug rau cov complexity thiab nyiaj ua hauj lwm.

3. Coj mus rau hauv tus account lub hom tam sim no noj: DC los yog AC.

Nws yuav tsum tau paub hais tias ib co welders yuav siv tau tam sim ntawd thiab ib tug lawm thiab alternating tam sim no. Qhov no yog tsim nyog rau lub vuam sib txawv ntawm cov ntaub ntawv, xws li txhuas thiab hlau. Welders muaj ib tug ntau ntawm cov tam sim no qhov tseem ceeb ntawm 3 mus rau 500 A.
