Lub vuam electrode, uas feem ntau hu ua "welding pas nrig," yog ib qho ntawm cov hlau nplaum uas muaj cov hlau nplaum uas tseem ua tau raws li kev muab tub lim thaum siv hauv cov txheej txheem vuam hu ua " shielded hlau arc vuam "or SMAW.

Raws li txoj cai, cov khoom siv twg yog siv rau hauv vuam pas nrig?

Vuam rods feem ntau siv alloys ntawm ob peb cov ntaub ntawv . Raws li online vuam cov ntaub ntawv xov xwm Vuam Tshuab Tshuab, peb feem ntau vuam rods tso cai rau kev koom los yog tsim ntau yam hlau alloys: tooj liab coated me me hlau alloy, siab carbon steel alloy thiab 3 feem pua nickel steel alloy.

Ib yam li ntawd, 7018 vuam pas nrig siv rau dab tsi? Cov 7018 arc welding pas nrig feem ntau yog siv rau lub hom phiaj vuam ntawm carbon steel. Nws yog ib qho hlau me me rod uas yog coated nrog ib tug tsawg-hydrogen, hlau-raws li flux compound uas vaporizes los tiv thaiv lub molten vuam hlaws los ntawm kev sib kis los ntawm huab cua thiab noo noo.

Ib yam li ntawd, tib neeg nug, tus pas nrig twg siv rau hauv arc vuam?

Kuj tseem hu ua Gas Tungsten Arc Vuam (GTAW), siv cov tungsten electrode uas tsis yog siv los tsim cov arc thiab ib qho inert shielding roj los tiv thaiv cov vuam thiab molten pas dej ua ke tiv thaiv atmospheric paug.

Cov tshuaj dab tsi yog siv rau hauv vuam?

Gases siv hauv vuam thiab txiav cov txheej txheem suav nrog:

  • shielding gases xws li carbon dioxide, argon, helium, thiab lwm yam.
  • roj gas xws li acetylene, propane, butane, thiab lwm yam.
  • oxygen, siv nrog roj gases thiab kuj nyob rau hauv me me nyob rau hauv ib co shielding roj sib tov.
