I have a query about The Duplex cladded E quipment having base material SA 516 Gr70 of 50mm thk and clad of Duplex (3mm )
The eqipment require to undergo PWHT at 600C The Joint is clad restored by Duplex weld
i) Does the PWHT at 600C will affect the Corrosion properties of Duplex weld (Corrosion test like IGC,Pitting corrosin,etc as per GS8)
ii) If yes do we require to carry out PWHt at lower Temp.
