Mr. Dutta,
You have mentioned that, 'I would have thought that the flat sheets should be
plugwelded to geta single sheet of 36 mm thickness (30 mm SA 516 Grade 70
with 6 mmSuperduplex SS lining) and then the entire 36 mm sheet could be
rolled. However our contractor informs that there could be problems in
the strength of the plug weld and the joints could fail on Rolling.'
As you have rightly pointed out, the SS with higher thick CS could be plugged together
and then rolled. No problems will arise as long as the weld is sound and with proper fusion..
It is a common practice and radiography / Ultrasonic test could be taken at random (or) fully to
check the quality of the weld if required.
Since you are going to use a SS consumable, the ductility will not be a problem and the rolling
will be successful and you can go ahead positively.
