When is sectioning utilized in repair processes?

Sectioning is utilized in repair processes primarily for restoring damage that extends through the component's full profile. This technique involves cutting out a damaged section of the material and replacing it with a new piece, effectively addressing extensive damage that cannot simply be repaired by surface treatments or minor adjustments. By removing and replacing the damaged portion, sectioning ensures that the structural integrity and functionality of the component are maintained.

This approach is crucial when the damage impacts the entire profile of the component, as it allows for a more thorough and reliable repair. It involves precise measurements and alignment to ensure that the replacement section fits seamlessly and performs well.

In contrast, other options refer to situations that do not necessitate such an involved repair technique. For example, addressing minor damages with heat, handling small dents, or replacing components entirely are less complex processes that do not require sectioning, as they can often be resolved with simpler repair methods.
