Cov txheej txheem vuam rau Incoloy 825
1. Npaj:
Ntxuav cov khoom siv los tshem tawm cov paug tsis huv, roj, roj, lossis oxides.
Preheat feem ntautsis tas yuav, tab sis tuaj yeem siv (100-150 degree) rau cov ntu thicker kom txo thermal kev ntxhov siab.
2. Vuam Txoj Kev:
Tig (Gtaw)thiabMIG (GMAW)feem ntau siv rau incoloy 825.
Pas vuam (smaw)Nrog cov tshuab hluav taws xob tau sib haum kuj ua tau.
3. Cov Khoom Siv Khoom Siv:
Kev sivSib phim cov tub rogxws li ernicrmo -3} lossis sib npaug nrog cov tshuaj sib thooj kom zoo sib xws rau Incoloy 825.
Cov xua hlau los yog cov pas nrig yuav tsum phim cov hlau hauv paus kom ntseeg tau corrosion tsis kam thiab cov khoom siv neeg kho tshuab.
4. Tiv thaiv cov roj:
Kev sivArgon lossis Argon \/ Helium MixturesTxhawm rau tiv thaiv lub pas dej weld los ntawm oxidation.
5. Interpass Kub:
Ua hauv qab no300 Degreekom tsis txhob carbide nag lossis daus thiab intergranular corrosion.
6. Post-Weld Kev Kho Mob:
Feem ntau, incoloy 825 uatsis tas yuav tsum tau muab tshuaj tua hluav taws xob tom qab Weld (duab).
Kev ntxhov siab tau ua tau yog tias tsim nyog, tab sis feem ntau yog zam kom muaj kev tswj hwm corrosion.
7. Vuam tsis muaj:
Siv cov tshav kub tsis tshua muaj cua sov los txo cov distortion thiab tswj weld zoo.
Tswj vuam ceev thiab amperage raws li tuab thiab sib koom ua ke tsim.
