Dear all
Large number of minor Cracks of 5 to 10mm (Not visible in Co 60 Radiograhy)while Gauging few locations in carbon steel casting (WCB) of large section thickness 150 to 170mm. Number of cracks increases while gouging
Can anyone throw light on this behaviour?
How to handle / salvage ?

The subject casting is Taper Plug Valve Body.
Though there is a belly riser, the defects are spreading all thro the thickness much away from the riser also.
When we weld , we notice crack at the joining layer with the parent metal also. We have seen crack on the opposite side to rise also. We feel it is not related to the riser leffect. Pl advise.Regards
