Experience in maintenance and repair services for Gas Turbine hot gas path parts

Throughout the years, ATLA has increased experience, rendering excellent quality services.

Our facilities in Chieri focus on the repair of Gas Turbine hot gas path parts, mainly blades and vanes, as well for power generation as for aircraft industry. Our high specialized services are fundamental for Gas Turbine efficiency; to ensure the best possible services to our Customers, ATLA provides comprehensive technologies and customized repair solutions.

Over 500.000 stripped, repaired and coated parts

Maintenance is fundamental to ensure optimum performances.

Our Facilities repair rotor and stator blades and other gas turbine hot path parts and deliver these parts “as new” relying on our long experience.

Preliminary Inspection and Testing

We offer a range of Non Destructive and Destructive Testing services. Carrying out testing tasks is fundamental in order to make sure that quality and safety standards are met.

Each inspection process provides a detailed list of the detected defects’ features, determining whether or not the part is suitable for its desired function. During the whole manufacturing process, starting from the incoming inspection of the raw material, all individual parts are monitored and inspected by our Quality Department.
