For which condition is sectioning a recommended repair method?

Sectioning is a recommended repair method specifically for restoring full-profile damage. This technique involves cutting out the damaged section of the container and replacing it with a new piece that matches the existing structural profile of the container. This approach is essential when the damage is significant enough that surface repairs alone won't suffice to maintain the integrity and safety of the container.

When dealing with full-profile damage, it is crucial to ensure that the structural characteristics are intact. Simple surface repairs would not adequately address the potential for structural weaknesses, making sectioning a more effective and necessary method. This allows for a thorough repair that restores the container to its original strength and functionality.

In contrast, other scenarios, such as small indentations, minor weld repairs, or surface scratches, often require different repair techniques that do not involve extensive cutting and replacing of material. These methods are tailored to less severe damage, where simpler, less invasive repairs can maintain the integrity of the container without needing a full section replacement.
