Structural reinforcement of pipelines by welding is a widely used technique to restore or improve the integrity and strength of compromised pipeline systems. This method is particularly effective in situations where there are cracks, corrosion or other types of degradation. Welding offers a robust solution for pipeline repairs, allowing the fusion of materials that, when properly performed, can equal or even exceed the mechanical properties of the original material. Welding is applied based on specific standards and procedures that ensure the quality and safety of the repair.
