Radiography / X-ray Inspection
Radiographic Inspection
Radiographic Inspection makes use of x-rays to produce an internal image of a casting (or part of a casting) on film, seeking out any internal defects. Our x-ray facility incorporates two x-ray cells (225 kv + 320 kv) for use on both aluminum and steel castings. Using an automatic processor, images are produced on film and inspected against customer and industry standards for compliance.
We employ multi-disciplined inspectors who are able to work in both of our NDT departments. All are qualified to NAS 410 / EN4179 + PCN level II. In addition to our Level II members of staff we also have an on-site Level III, who is qualified to write and sanction our own process techniques without any assistance from an external source.
Both departments are fully Nadcap approved and are currently on the PRI Merit program (24 month audits) following eight previous successful audits.
Sub-contract testing service
In addition to carrying out NDT inspections of our own castings Maycast-Nokes also offers a sub-contract NDT service, inspecting components manufactured by other companies to their required standards – please contact Tony Mays (tmays@maycast.co.uk) for further information.
Radiography frequently asked questions
Common questions about radiography inspection, X-ray testing and how we verify internal casting integrity for demanding industries.
-
Radiography is a critical nondestructive testing method that allows us to examine the internal integrity of aluminium castings without altering or damaging the part. Using advanced Xray imaging, we can detect porosity, inclusions, cracks, and other internal features that are vital to performance – particularly in safety sensitive sectors such as aerospace.
As a NADCAP approved radiography provider, supported by an onsite PCN Level III specialist, we carry out all radiographic inspection in our two purpose built bays here in Halstead. Every inspection is fully documented and retained in line with aerospace quality system requirements, ensuring complete traceability for our customers.
-
Radiographic inspection can identify a wide range of internal casting defects, including Porosity (gas pores, shrinkage cavities); Inclusions (nonmetallic particles or foreign material); Cracks or hot tears; Wall thickness variations and Internal mis-runs or cold shuts.
These findings help ensure that only structurally sound castings move forward in the manufacturing process.
-
Radiography is especially important in aerospace applications, where even a small internal defect can compromise performance or safety. To support these requirements, our company holds NADCAP accreditation for Radiography, and all work is overseen by an on‑site PCN Level III Radiography and PFD Specialist.
-
All radiographic inspections are carried out, sentenced and certified in accordance with aerospace quality‑system requirements. Documentation typically includes film images; Inspection reports and acceptance criteria; Operator qualifications; Equipment settings and traceability data, as well as any non‑conformance findings and disposition.
-
Yes – All radiographic inspection is carried out in-house at our Halstead facility. We operate two dedicated radiography bays, allowing us to manage inspection schedules efficiently and maintain full control over quality, safety, and turnaround times.
