Iyo yakanakisa tungsten electrode kune chaiyo application zvinoenderana nezvinhu zvakaita semhando yewelding, welding material uye welding current. Zvisinei, mamwe anowanzo shandiswa tungsten electrodes anosanganisira:

1. Thoriated tungsten electrode: inowanzoshandiswa kuDC welding yesimbi isina tsvina, nickel alloy uye titanium. Ivo vane yakanaka arc kutanga uye kugadzikana zvivakwa.

2. Tungsten-cerium electrode: inokodzera AC uye DC welding, inowanzoshandiswa pakugadzira carbon steel, simbi isina tsvina, nickel alloy uye titanium. Ivo vane yakanaka arc yekutanga zvivakwa uye yakaderera kupisa mitengo.

3. Lanthanum Tungsten Electrodes: Aya ndiwo magetsi akasiyana-siyana akakodzera AC uye DC welding ye carbon steel, Stainless steel, nickel alloys uye titanium. Ivo vane yakanaka arc kugadzikana uye hupenyu hurefu hwebasa.

4. Zirconium tungsten electrode: inowanzoshandiswa kune AC welding yealuminium uye magnesium alloys. Vane kupikisa kwakanaka kusvibiswa uye vanopa arc yakagadzikana.

Izvo zvakakosha kubvunza nyanzvi yewelding kana kutaura kune chaiwo welding application madhairekitori kuti uone yakanakisa tungsten electrode yerimwe basa rewelding.

Tungsten haina kusimba kupfuura dhaimondi. Dhaimondi ndechimwe chezvinhu zvakaoma zvikuru zvinozivikanwa uye inoratidzirwa nekuoma kwakasiyana uye kusimba. Inoumbwa nekabhoni maatomu akarongwa mune chaiyo crystal chimiro, iyo inopa iyo yakasarudzika zvimiro.

Tungsten, kune rumwe rutivi, isimbi yakakora uye yakasimba ine nzvimbo yakakwirira yekunyungudika, asi haina kuoma sedhaimani. Tungsten inowanzoshandiswa mumashandisirwo anoda simba rakawanda uye kupisa kupisa, sekugadzira maturusi epamusoro-soro, mabatiro emagetsi, uye indasitiri yemuchadenga.

Muchidimbu, nepo tungsten chinhu chakasimba uye chakasimba, haina kuoma sedhaimani. Dhaimondi rinoramba riri chimwe chezvinhu zvakaoma uye zvakasimba zvakanyanya zvinozivikanwa nemunhu.

Tungsten ine yakanyanya kunyungudika ye3,422 ° C (6,192 ° F), ichiiita imwe yepamusoro-soro yekunyungudika kwezvinhu zvese. Nekudaro, pane zvimwe zvinhu uye mamiriro anogona kunyungudutsa tungsten:

1. Tungsten pachayo: Tungsten inogona kunyungudutswa uchishandisa tembiricha yakanyanyisa inogadzirwa nemichina yakasarudzika yakadai semavira emagetsi arc kana dzimwe nzira dzekudziisa.

2. Tungsten-rhenium alloy: Kuwedzera zvishoma rhenium kune tungsten kunogona kuderedza nzvimbo yakanyunguduka yealloy. Iyi alloy inoshandiswa mune mamwe tembiricha yakakwira apo panoda kunyungudika yakaderera.

3. Tungsten inogonawo kunyungudutswa muhupo hwemamwe magasi anoshanda kana pasi pemamiriro ezvinhu chaiwo munzvimbo inodzorwa.

Kazhinji, kunyunguduka tungsten kunoda mamiriro akanyanya nekuda kwekunyungudika kwayo, izvo zvisiri nyore kuwana.
