Weld integrity is critical in industries such as aerospace, automotive, energy, and heavy manufacturing. Even minor flaws like porosity, cracks, or incomplete fusion can compromise safety, reliability, and compliance. Advanced Non-Destructive Testing (NDT) ensures that welded parts are defect-free without damaging the components.
XRAY-LAB specializes in comprehensive NDT services for welded parts, offering state-of-the-art 2D/2.5D X-ray, Industrial Computed Tomography (CT) and advanced software-driven defect analysis. Our global clients benefit from accurate, fast, and fully traceable inspection solutions.

In the aerospace sector, even the tiniest defect poses enormous risks. Be it microcracks within a turbine blade or voids within a composite fuselage panel, surreptitious flaws can compromise safety, a brand’s performance, and regulation certification. Thus, aerospace manufacturing quality control is not simply about compliance; it is about failure prevention in the most demanding and highly scrutinized environments.
Standard inspection techniques such as visual and ultrasonic evaluations are limited to the detection of surface and some subsurface anomalies. These methods would not provide insight into complex internal structures. In these cases, X-ray inspection and CT (Computed Tomography) scanning are crucial. These techniques are a form of non-destructive testing (NDT) and, as such, they permit manufacturers to assess aerospace components’ internal structures in detail without causing harm. X-ray technology is now a cornerstone of aerospace QA, helping manufacturers and MROs (Maintenance, Repair, and Overhaul providers) maintain rigorous safety, traceability, and compliance standards.

Key Weld Defects and Detection Methods
- Porosity Detection
Porosity occurs when gas becomes trapped during welding, forming voids that reduce mechanical strength.
XRAY-LAB Detection Methods:
- 2D/2.5D X-ray: Fast imaging for surface and near-surface porosity.
- Industrial CT: 3D volumetric imaging for precise pore mapping and measurement.
- Ultrasonic Testing (UT): Detects subsurface voids in thick or complex welds.
- Crack Detection
Cracks can appear internally or on the surface and may propagate rapidly under stress.
XRAY-LAB Detection Methods:
- CT Scanning: 3D visualization of internal cracks in complex weld geometries.
- Ultrasonic Testing: High-precision detection of planar cracks.
- 2D X-ray: Detects internal and surface-breaking cracks.
- Lack of Fusion & Incomplete Penetration
These defects occur when the weld metal fails to bond fully with the base material or adjacent passes.
XRAY-LAB Detection Methods:
- Ultrasonic Testing (UT & Phased Array UT): Excellent for locating planar defects and measuring depth.
- Industrial CT: Shows density inconsistencies and bonding gaps with 3D resolution.
- 2D/2.5D X-ray: Efficient for detecting incomplete fusion in production settings.
