welding overlay for compensating thickness loss
welding overlay for compensating thickness loss
(OP)
we have a pressure vessel of which the bottom shell portion (cylindrical) severely corroded due to which there is a thickness loss of 8 mm (original thickness was 34 mm and now it is 26 mm). There is an option of replacing the bottom shell course by new one but it will take a lot of time and we cannot afford plant shutdown for long time. For a quick fix we are thinking of developing a welding overlay over the corroded portion to compensate for the thickness loss. Is this solution in line with code?

What material?
Preheat required?
How are you going to supply clean air, power, lights, ventilation, fume exhaustion, supplies, and still have room to move around and grind and work?
