2.25Cr-1Mo 재질에 초층309L+ 308L로 Overlay된 압력용기에 표면에서 Deposit부분을 제거 한 후(단, 희석된 부분은 남아 있음) 2.25Cr-1Mo용 용접봉인 E9016-B3로 육성 용접이 가능한지를 알고 싶습니다. 희석된 부분에 의하여 어떠한 영향이 있는지를 알려 주시면 감사 하겠습니다. 이런 육성 용접부를 굽힘시험을 할 경우 Crack 발생 하는지를 알려 주시기를 부탁 합니다.
It may be expected the different melting temperature (M.T), about 120-150 deg.C between the diluted surface by 309L SS (lower M.T-on base metal) and new overlay welding surface by E9016-B3 (higher M.T-on weld metal). It means some cracks may appear after welding or during bend testing at the bond.
If the purpose of removing the 308 overlay is to eliminate of the chloride corrosion, ENiCrFe2 or 3 is recommended for the repair overlay welding.
Please do not hesitate to get in touch with me if you want to get further information.
