R1, R2 , R3 on vertical joint
R1, R2 , R3 on vertical joint
(OP)
Dear experts,
Is there any code states that if on the vertical joint of the shell plate on the same location there are more then 2 times repair, so that vertical joint shall be cut out.
I have an assumption that many repair on the same location will make that location is brittle due to many heat input during repair. This may be the reason behind.

RE: R1, R2 , R3 on vertical joint
What is the shell material and thickness?
What process was used to remove material and make the new welds?
Is this a water tank or gasoline tank?
Is this a mission critical tank or simple storage in the middle of a field?
RE: R1, R2 , R3 on vertical joint
Do you mean it is depend on shell material, thickness, repair method and product to be stored ?
Let say : material group III, 22 mm thick. product to be stored fire water.
Repair method : arc gouge and re weld by SMAW till 3 times on the same location.
Do we need to cut out and remove that vertical including HAZ area ?
