Peening Services & Applications

Shot Peening - Metal fatigue occurs during cyclic loading via tensile stress, which can cause a crack to start in highly stressed areas. Shot peening mitigates this by imparting a high magnitude, residual compressive stress at the surface in potential failure areas.

Laser Peening—Laser Peening (sometimes called Laser Shock Peening) drives deep plastic strain into a part, creating a high-magnitude residual compressive stress from 1 to 10 mm below the surface. This enhances the fatigue strength, durability, damage tolerance, and resistance to stress corrosion cracking of critical metallic components.

Ultrasonic Cavitation Peening—Ultrasonic cavitation peening produces shallow depths of peening, which is ideal for components with thin sections. This shallow depth improves the fatigue life of components with a thin cross-section

Shot Peen Forming - This process uses the compressive stress induced by controlled shot peening to change the component shape. Gentle curves within the material's elastic range are regularly formed to consistent tolerances. 

C.A.S.E. Isotropic Superfinishing - C.A.S.E. (Chemically Assisted Surface Enhancement) is a two-stage process consisting of shot peening followed by vibratory superfinishing.

Additive Manufacturing Post Processing - CWST has developed many additive manufacturing post processes, which have several benefits.
