Breaking the mold? Try eliminating the mold altogether.
Stress corrosion and thermal cycling cracks are common flaws discovered during outage inspections. A structural weld overlay (SWOL) is the addition of weld reinforcement material on the outside surface of a pipe to a sufficient thickness and extent to create a new structural barrier. Additionally, it places the inner diameter surface of the component in a more favorable compressive stress state. It has earned recognition as a safe, problem-free means of crack mitigation and pipe repair.
