Hi!

 

As base metal is of LAS ,  req  PWHT at min 650C  , Therefore suitable  consumable for clad restoration of 410 S clad is  E NiCr fe3 or NiCr Mo3

 

Preheat Temp . of base metal for barrier layer is 100 C , (No need of preheating  for subsequent layers.  min ,Interpass temp  is  175 max,  Welding Current – 110-120  Amp for 3 .2 dia electrode.
