through:
Cutting-edge white light scanning to
create a digital representation of your
parts and compares the image to an
existing 3-D model to show deviations from the original specs.
Shot-wire peen for coating surface finish
5-axis milling
Shot peen of blade roots
6-axis water jet
Coordinate Measurement Machine
(CMM) to measure geometric dimensions of components in order to give
a more precise analysis of the servicerun condition of a part.
5-axis grinding
Infrared thermography (IR)
5-axis rapid hole EDM
Radiographic testing (RT)
7-axis laser drilling/shaping

Multiple coating techniques
Latest technology in machine tools
Ultrasonic testing (UT)
Eddy current testing (ET)
Fluorescent penetrant inspection

Machining and verification of turbine
parts: Advanced equipment is used to
machine and verify components. The
fiber-optic laser welder with vision system permits precise and accurate weld
build-up on complex material structures.
The axis milling and grinding machines
probe and recreate OEM airfoil and
shroud profiles. Robotic APS and HVOF
coaters repeat programmed paths for
consistent applications. Portable and
table coordinate measuring machines
verify geometries with the utmost precision. Calibrated fixtures ensure that
components meet OEM specifications.
Full in-house coating capabilities: The
Winston-Salem Service Center utilizes a
fully closed-loop control system for APS
and HVOF coating of turbine parts. We
have multiple coating booths to handle
specialized coating needs for TBC, wear
resistant coatings (Chrome Carbide,
T-800) and many other advanced coating techniques and materials. We have
a full range of capabilities in-house to
meet all of your coating needs, for combustion components, turbine blades and
vanes.
In-house product modifications:
As turbine parts are modified and
upgraded, we can implement these
design changes during the repair
process to help enhance product
reliability and plant efficiency.
Component identification: Siemens’
repair facilities engrave a unique identifier on each part, which allows us to
track every component during its service life cycle. We share this information
with our customers, as it helps maintain
a valuable part history for future reference.
Specialized component containers:
Siemens offers all-weather shipping
containers, specifically engineered to
house the critical-to-quality elements
of your parts for better protection
during transport and storage.
