Tuscorrosion tsis kam ntawm weld cheeb tsam hauv Q550NHERDER STEELMuaj peev xwm txo cov ntawv tshaj tawm -} vuam yog tias kev ntsuas tsis tau ua, tab sis qhov no tuaj yeem raug txiav nyom. Nov yog vim li cas thiab yuav ua li cas:
1. Yuav txo qis hauv corrosion tsis kam
Thaum tshav kub kub -} cuam tshuam thaj chaw (Haz):Lub siab kub ntawm vuam yuav hloov microstructure, txo qhov ua tau zoo ntawm alloying ntsiab (CU, NI) uas ua tus tiv thaiv pina.
Weld Hlau Composition:Cov chaw ua cov tub ntxhais ua cov hlau yuav tsis muaj huab cua txaus, tsim kom "qhov txuas tsis muaj zog" hauv corrosion tsis kam.
2. Kev Pab Tswv Yim
Siv Worireing - Tsis kam ua cov tub rog:Xaiv cov hluav taws xob / cov xov hlau sib txuam Q550NH txoj kev sib xyaw (piv txwv li,AWS E7015-W2lossis sib npaug).
Tshaj tawm -} Weld Tu:Tshem tawm slag / spatter thiab maj mam zom cov weld los txhawb cov khaub ncaws tsis sib haum txheej txheej txheej.
Nraum Huab Cua:Ua key cyclic ntub / kev kho mob kom qhuav rau lub chaw weld rau dhia patina kev txhim kho.
3. Ntev -} sij hawm ua haujlwm
Yuav muaj kev sib koom ua ke welded welded yuav kawg tsim kev tiv thaiv patina, tab sis cov txheej txheem yuav siv sijhawm ntev dua li cov hlau.
