MRO – Shot Peening Services

SONATS provides its ultrasonic MRO (maintenance, repair and overhaul) shot peening services directly at customer sites worldwide using manual and automated portable equipment. Our subcontracting shot peening activity work is conducted at our Carquefou workshop (44, France), for offloading or series production.

Using manual and automated industrial equipment designed and manufactured by SONATS, our qualified and experienced team of MRO technicians has been providing quality service for over 30 years.

Example of Shot peening services on steam turbine

Shot peening treatment before putting into operation turbines in order to increase their fatigue life cycle.

During last subcontracting service, 4 technicians process for two weeks to the treatment of turbine Fir Tree Groove.

The team was equipped with 4 ruggedized portative equipment, STRESSVOYAGER®, each of it capable of activated simultaneously two treatment heads to shot peen a total of 8 areas at the same time in order to reduce the overall treatment period.

Prior to the service, an entire qualification process has been realized on a representative model of the part to define the treatment parameters to reach the residual stresses, rugosity and coverage required.

This process qualification lasted around one month and enables now to operate on every turbine of the same model without doing again the development process.

The pluses of our shot peening services

HERMETIC PEENING

No risk of media loss allows us to ensure ultrasonic shot peening treatment directly on assembled elements (SONATS on-site treatment for transportable sub-assemblies, treatment directly in-situ for non-transportable assemblies).

Sealing the treatment chamber allows us to use a very small amount of balls for shot peening. We take advantage of this advantage to use very high quality media (bearing balls) to achieve a very good surface state (low roughness).

LOCALISED PEENING

Ultrasonic shot peening parts do not need to be masked beforehand so our cycle times are low and our lead times are very competitive.

STRESSONIC® technology allows us to treat your parts without disassembly, either directly in your workshops or on the equipment.

Our trained, qualified teams provide quality services with great responsiveness. Our main advantage: minimise the downtime of your equipment.

MRO SERVICES AT CUSTOMER’S SITES

All MRO shot peening services can also be carried out directly at our customer’s sites using portable equipment.

SONATS outsources ultrasonic shot peening services directly to its customers around the world.

Thanks to long-term partnerships combined with trained and qualified teams, SONATS provides quality and responsive services. SONATS portable solutions are designed to treat your parts directly on site.
