Weld a support plate over the horizontal and vertical welding lines a tank.
Weld a support plate over the horizontal and vertical welding lines a tank.
(OP)
Hello all,
I want to know if it is common to weld support pads on the tank shell , if the welding lines are over the welding lines of the tank.
if it is not possible what is the reason?
see attached picture.

the tank is ASTM A36. Do you know if API 650 has information about this?
thanks

For your tank it is allowed but it is still not the best practice.

I don’t have a copy of API 650 in front of me. But, normally it is not good practice to weld into or across other welds because of the potential for intersecting high residual weld stress in the welds and the HAZ regions of the welds. These residual stress fields are perpendicular to each other and lead to nasty tri-axial stress conditions. Additionally, you want to be careful not to leave any start/stop stress raisers in these areas. Obviously, there are times when these types of conditions can not be avoided, and they need special attention to details.
