Incoloy 800 vuam txheej txheem
1. Npaj:
Cov khoom siv huv huv cov hlau kom huv si kom tshem tawm cov paug tsis xws li roj, roj, thiab oxides.
Preheat feem ntau yogtsis tas yuav, but for thick sections (>25 hli), preheating rau ib ncig 150 degree (300 degree f) tuaj yeem pab txo cov kev ntxhov siab.
2. Vuam Txoj Kev:
Haum vuam txoj kev:Tige (GTAWW), MIG (GMAW), SMAW (STRAW), thiab ntshav vuam.
Siv cov hlau uas siv tau tshaj nrog Incoloy 800, xws liErnicr -3 (inconel 82)lossisErnicr -4 (inconel 625)Rau kev ua kom zoo nkauj thiab cov tshuab siv tshuab.
3. Qaug Kub:
Ua kom muaj qhov kub nyob hauv qab260 Qib (500 Degree F)Txhawm rau kom tsis txhob mob carbide nag lossis tswj hwm corrosion.
4. Cua sov tawm tswv yim:
Siv cov kev tawm ua cua sov sim kom tsis txhob muaj cov nyom loj hlob thiab tawg.
5. Post-Weld Kev Kho Cua Sov (PWHT):
Feem ntau,PWHT tsis tas yuavrau incoloy 800.
Yog tias pwht yog thov, kev ntxhov siab yog nyob rau ntawm870-950 degree (1600-1740 Qib F)rau 1-2 teev.
6. Tiv thaiv cov roj:
Siv cov kev coj dawb huv siabArgon lossis Argium-Helium MixturesTxhawm rau tiv thaiv lub pas dej weld.
Cov Lus Qhia Ntxiv
Zam kev ua kom txias sai kom txo cov kev ntxhov siab uas tsawg.
Tswj vuam vuam tsis muaj kev tiv thaiv kub tawg.
Rau cov ntawv thov tseem ceeb, ua cov txheej txheem kev siv kev ua yeeb yam vuam.
