Tie rod bolts that connect gas turbine stages are susceptible to fretting fatigue at the edge of the contact region between the turbine rotors and the tie rod landings. Learn how it can be mitigated in this Power Magazine article.

Turbines are the backbone of power generation, so maintaining top performance of all their moving parts is important for continued, efficient operation.

Welding can leave tensile residual stresses in and around the heat-affected zone, increasing susceptibility to fatigue and stress corrosion cracking.

Engineered compression provides a way to modify that residual stress state by introducing deep, stable compression in critical areas.

In this interview, our VP of Operations discusses how optimized burnishing can be applied to welded components and the role residual stress plays in their performance.

The act of welding induces stress into the material, so metal fabricators employ various methods to mitigate it. One technique is low-plasticity burnishing, a high-tech cousin of the old-school burnishing process.

Deep compression is an effective repair and life-extension solution for steam turbine components affected by fatigue, stress corrosion cracking (SCC), and other forms of surface damage.

This article published in Turbomachinery International examines how engineered compressive residual stress can be used during manufacturing or repair to improve damage tolerance and extend component life.

For power plants, these improvements can help reduce downtime and recurring maintenance while improving the reliability of critical turbine components.
