Dab tsi Shielding Gas yuav tsum tau siv rau Laser Vuam Tshuab?
Shielding gas plays lub luag haujlwm tseem ceeb hauv laser vuam zoo. Xaiv cov roj kom raug tuaj yeem txhim kho qhov zoo li vuam, nkag mus, thiab kev ua haujlwm tag nrho.
Vim li cas Shielding Gas tseem ceeb?
Thaum lub sij hawm vuam, shielding gas tiv thaiv lub pas dej molten los ntawm oxidation thiab paug.
Kev xaiv roj kom zoo pab:
Txhim kho weld zoo
Txo cov spatter
Nce nkag
Txhim khu weld tsos
Common Shielding Gases
Nitrogen (N₂)
Nitrogen yog dav siv thaum vuam stainless hlau.
Qhov zoo:
Smooth weld tsos
Bright weld nto
Tus nqi ua haujlwm qis dua
Tej kev siv:
Cov khoom siv hlau stainless
Cov khoom siv hauv chav ua noj
Kho kom zoo nkauj hlau fabrication
Argon (zeeg)
Argon feem ntau yog siv rau txhuas thiab tooj liab vuam.
Qhov zoo:
Weld tiv thaiv zoo heev
Kev ruaj ntseg vuam kev ua tau zoo
Txo oxidation
Tej kev siv:
Aluminium qauv
Copper Cheebtsam
Precision vuam
Compressed Cua
Cov cua compressed tuaj yeem siv rau qee qhov kev siv carbon steel.
Qhov zoo:
Tus nqi qis heev
Yooj yim muaj
Txawm li cas los xij, weld tsos yuav tsis zoo li thaum siv nitrogen lossis argon.
Pom zoo xaiv Gas
| Khoom siv | Pom zoo Gas |
|---|---|
| Stainless hlau | Nitrogen |
| Carbon Steel | Nitrogen / Cua |
| Aluminium | Argon |
| Tooj | Argon |
Xaus
Xaiv txoj cai shielding roj yog qhov tseem ceeb rau kev ua tiav cov vuam zoo. Nitrogen feem ntau pom zoo rau cov hlau tsis muaj steel, thaum argon yog nyiam rau kev siv txhuas thiab tooj liab. Kev xaiv roj kom zoo tuaj yeem txhim kho cov khoom tsim tau thaum txo qis cov khoom tsis xws luag.
