ER385 Stainless hlau vuam qws
Lus piav qhia luv luv:
ER385 yog ib hom vuam muab tub lim hlau, tshwj xeeb yog stainless hlau electrode."ER" sawv cev rau "Electrode lossis Qws," thiab "385" qhia txog cov tshuaj muaj pes tsawg leeg thiab cov yam ntxwv ntawm cov hlau muab tub lim.Hauv qhov no, ER385 yog tsim los rau vuam austenitic stainless hlau.
ER385 Vuam pas nrig:
Austenitic stainless hlau, xws li Hom 904L, muaj cov qib siab ntawm chromium, npib tsib xee, thiab molybdenum, ua rau lawv cov corrosion-resistant thiab haum rau siv nyob rau hauv ib puag ncig hnyav.ER385 vuam rods feem ntau yog siv rau hauv daim ntawv thov uas corrosion kuj yog ib qho tseem ceeb, xws li nyob rau hauv cov tshuaj, petrochemical, thiab marine industries.ER385 vuam rods yog haum rau ntau yam vuam txheej txheem, xws li shielded hlau arc vuam (SMAW), roj tungsten arc. welding (GTAW or TIG), thiab gas hlau arc vuam (GMAW lossis MIG).

Dab tsi yog cov yam ntxwv ntawm ER385 Vuam Hlau?
1. Kev tiv thaiv corrosion zoo heev, tuaj yeem tiv taus corrosion tsis zoo ntawm sulfuric acid thiab phosphoric acid, tiv thaiv corrosion ntawm acetic acid ntawm txhua qhov kub thiab txias nyob rau hauv ib txwm siab, thiab tuaj yeem daws tau zoo pitting corrosion, pitting corrosion, crevice corrosion, kev nyuaj siab corrosion thiab lwm yam teeb meem ntawm halides.
2. Lub arc yog mos thiab ruaj khov, nrog tsawg spatter, zoo nkauj zoo nkauj, zoo slag tshem tawm, ruaj khov hlau noj, thiab zoo heev vuam txheej txheem kev ua tau zoo.
Vuam txoj haujlwm thiab cov khoom tseem ceeb:
1. Siv cov khoom thaiv tsis zoo thaum vuam nyob rau hauv qhov chaw uas muaj cua daj cua dub kom tsis txhob muaj cua tshuab los ntawm cua.
2. Qhov kub ntawm qhov kev hla yog tswj ntawm 16-100 ℃.
3. Cov dej noo, xeb stains thiab roj stains ntawm qhov chaw ntawm lub hauv paus hlau yuav tsum tau muab tshem tawm tag nrho ua ntej vuam.
4. Siv cov pa roj CO2 rau vuam, qhov purity yuav tsum siab tshaj 99.8%, thiab cov roj ntws yuav tsum tau tswj ntawm 20-25L / min.
5. Qhov ntev ntev ntawm cov vuam hlau yuav tsum tau tswj nyob rau hauv qhov ntau ntawm 15-25mm.
6. Tom qab unpacking welding hlau, thov nco ntsoov: siv cov dej-pov thawj ntsuas, siv nws kom sai li sai tau, thiab tsis txhob cia cov vuam hlau tsis siv nyob rau hauv cov huab cua ntev.
