Kev xaiv cov khoom siv vuam tsis raug rau Q415NH Corten Steel feem ntau ua rau muaj teeb meem kim heev -weld tawg, txo kev sib koom ua ke, los yog tsis zoo corrosion kuj uas ua rau cov hlau ua haujlwm sab nraum zoov. Raws li qhov nruab nrab -lub zog siab Corten Steel, Q415NH xav tau cov khoom siv uas haum rau nws cov khoom siv dag zog thiab huab cua- cov khoom tiv taus, tab sis ntau tus neeg yuav khoom tsuas yog siv cov khoom siv hluav taws xob tsim los rau cov hlau zoo tib yam. Yog li, cov khoom siv vuam siv tau zoo li cas nrog Q415NH, thiab yuav ua li cas kom ntseeg tau tias muaj kev ntseeg siab, ntev ntev -welding? Raws li GB / T cov qauv thiab kev siv vuam, cov lus teb tseem ceeb yog qhov tseeb:Q415NH Corten Steel yuav tsum muaj tsawg-hydrogen, nruab nrab- siab zog vuam consumables uas phim nws 415MPa yield zog thiab muaj corrosion- tiv taus cov ntsiab lus- haum rau cov txheej txheem vuam sib txawv. Hauv qab no yog cov lus qhia yooj yim, ua tau zoo.
Cov Ntsiab Cai Tseem Ceeb ntawm Kev Ua Tau Zoo (Critical for Success)
Cov khoom siv raug cai rau Q415NH yuav tsum ua tau raws li ob qhov tsis yog - cov txheej txheem sib tham tau - hla ib qho, thiab kev ua haujlwm vuam yuav raug kev txom nyem:
Lub zog sib tw: Cov khoom siv yuav tsum muaj qhov tsawg kawg nkaus lub zog ntau dua los yog sib npaug ntawm 415MPa kom ntseeg tau tias qhov sib koom ua ke muaj zog zoo li Q415NH hauv paus hlau, zam cov ntsiab lus tsis muaj zog hauv kev siv cov qauv.
Corrosion Resistance Match: Consumables yuav tsum muaj cov kab Cu, Cr, los yog Ni (tib yam li Q415NH) kom cov weld tsim ib tug uniform patina nrog lub hauv paus hlau, tiv thaiv lub zos corrosion.
Tsawg-Hydrogen Yuav Tsum Tau: Cov dej noo hauv cov khoom siv ua rau cov kab mob txias hauv Q415NH welds-ib txwm siv qis- hydrogen consumables thiab khaws cia kom zoo.
Pom zoo Vuam Consumables los ntawm txheej txheem (Cov Tswv Yim Qhia)
Hauv qab no yog cov txheej txheem vuam ntau tshaj plaws rau Q415NH, ua ke nrog cov khoom siv sib xws thiab cov lus qhia tseem ceeb:
1. Shielded Hlau Arc Vuam (SMAW) - Feem ntau rau ntawm -Qhov Chaw Ua Haujlwm
Pom zoo Consumables: E5515-G (AWS A5.1) los yog E5516-G electrodes-cov no yog cov low-hydrogen, nruab nrab-siab zog, thiab muaj cov kab mob corrosion-resistant.
Ntsiab Lus Qhia: Qhuav electrodes ntawm 350-400℃rau 1-2 teev ua ntej siv kom tshem tawm cov dej noo; khaws cov electrodes uas tsis siv rau hauv lub txee qhuav.
2. Gas Metal Arc Vuam (GMAW/MIG) - Rau siab -Efficiency Fabrication
Pom zoo Consumables: ER55-G or ER55-Ni solid wires (AWS A5.18), paired with Ar+CO₂ (80/20) shielding gas.
Cov Lus Qhia Tseem Ceeb: ER55-Ni yog qhov nyiam rau qhov chaw txias (-10℃thiab hauv qab no) vim nws txhim kho qhov tawv tawv, txo qhov kev pheej hmoo tawg.
3. Gas Tungsten Arc Vuam (GTAW/TIG) - Rau Precision Welds
Pom zoo Consumables: ER55-G los yog ER55-Ni muab tub lim (AWS A5.28)-zoo tagnrho rau nyias daim hlau (tsawg dua los yog sib npaug rau 10mm) los yog hniav welds qhov twg zoo li zoo li.
Ntsiab lus tseem ceeb: Siv cov pa ntshiab Ar shielding gas rau ntxuav welds; tsis txhob kis tus kab mob ntawm cov pas nrig los tiv thaiv corrosion.
Tswv yim Matching Tips & Common yuam kev
Tswv yim 1: Rau cov phaj tuab (＞ 20mm), siv E5515-G electrodes nrog preheating (80-120 degree) los txo cov kev ntxhov siab vuam.
Tswv yim 2: Tom qab welding, ntxuav weld spatter tam sim ntawd -spatter cuam tshuam kev tsim patina thiab tuaj yeem ua rau xeb hauv zos.
Ua yuam kev kom tsis txhob: Siv cov khoom siv E4313 lossis ER49 zoo tib yam-1 khoom siv-cov no muaj zog heev thiab tsis muaj cov khoom tiv thaiv corrosion, ua rau
