Radioactive Specimen Manufacture
-
Within the Walton House Active Laboratory, Wood has the capability to produce a variety of complex geometry test specimens from a range of materials. The capabilities include:
-
Wire Electric Discharge Machining (WEDM)
-
Precision Knee-Mill, with digital readout
-
Diamond Wheel slit saw and Lathe
-
Band saw for large sample sectioning
-
Lead-lined glove-box with machining capabilities for high activity materials, previously used for ex-service graphite and contaminated steel components.
Wood have a team of design engineers, who can produce specimen and extraction drawings to customer requirements.
Non-Active Sample Manufacture
The capabilities listed above can also be used for machining of non-active materials, but in addition, Wood has two non-active machining facilities with the following capabilities
-
3 off knee-milling machines
-
3 off precision lathes
-
A horizontal surface grinder, with precision feed and position controls for optimised surface finish
-
Welding capabilities
-
Large band saw, with support apparatus
A non- active metallographic preparation facility is available for mounting and preparing samples for metallographic analysis (e.g. SEM, XRD, Micro-hardness, fractography, etc.).
Example Specimens Manufactured at Wood:
-
‘Dog-bone’ tensile specimens extracted from contaminated plastic pipe
-
Charpy Impact samples from ex-service stainless steel
-
M6 round tensile test specimens from ex-service weldment
-
Curved ‘dog-bone’ creep specimen from contaminated ex-service stainless steel
-
Activated Magnox Graphite 4-point bend and tensile specimen
-
316 Stainless steel 12mm and 25mm compact tension fatigue samples
-
Active graphite thermal diffusivity and CTE samples
-
Flat section cross-weld tensile samples extracted from curved sections of stainless steel pipe
