ER385 Stainless Hlau Vuam Qws
Kev Piav Qhia Luv:
ER385 yog ib hom hlau vuam, tshwj xeeb yog hlau tsis xeb electrode. Tus "ER" sawv cev rau "Electrode lossis Rod," thiab "385" qhia txog cov tshuaj lom neeg thiab cov yam ntxwv ntawm cov hlau filler. Hauv qhov no, ER385 yog tsim los rau kev vuam austenitic stainless hlau.
ER385 Vuam Qws:
Cov hlau tsis xeb Austenitic, xws li Hom 904L, muaj cov chromium, nickel, thiab molybdenum ntau heev, ua rau lawv tiv taus xeb heev thiab tsim nyog siv rau hauv qhov chaw ib puag ncig hnyav. ER385 vuam rods feem ntau siv rau hauv cov ntawv thov uas tiv taus xeb yog qhov tseem ceeb, xws li hauv kev lag luam tshuaj lom neeg, petrochemical, thiab marine. ER385 vuam rods yog tsim rau ntau yam txheej txheem vuam, suav nrog shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW lossis TIG), thiab gas metal arc welding (GMAW lossis MIG).

Cov yam ntxwv ntawm ER385 Vuam Hlau yog dab tsi?
1. Kev tiv thaiv xeb zoo heev, tuaj yeem tiv taus kev xeb ntawm sulfuric acid thiab phosphoric acid, tiv taus kev xeb ntawm acetic acid ntawm txhua qhov kub thiab txias hauv qab qhov siab ib txwm muaj, thiab tuaj yeem daws tau qhov xeb pitting, pitting corrosion, crevice corrosion, stress 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 pub, thiab zoo heev vuam txheej txheem kev ua tau zoo.
Cov hauj lwm vuam thiab cov khoom tseem ceeb:
1. Siv cov khoom thaiv cua thaum vuam hauv cov chaw cua kom tsis txhob muaj qhov cua tshuab los ntawm cua hlob.
2. Qhov kub ntawm cov hla dhau yog tswj tau ntawm 16-100 ℃.
3. Cov dej noo, cov xeb thiab cov roj ntawm qhov chaw ntawm cov hlau hauv paus yuav tsum tau muab tshem tawm tag nrho ua ntej vuam.
4. Siv cov roj CO2 rau kev vuam, qhov huv yuav tsum ntau dua 99.8%, thiab cov roj ntws yuav tsum tswj tau ntawm 20-25L / feeb.
5. Qhov ntev ntawm cov hlau vuam yuav tsum tau tswj kom tsis pub dhau 15-25 hli.
6. Tom qab qhib cov hlau vuam lawm, thov nco ntsoov: ua cov txheej txheem tiv thaiv dej noo, siv nws sai li sai tau, thiab tsis txhob tso cov hlau vuam uas tsis tau siv rau hauv huab cua ntev.
