Weld radiographic testing (RT) is a cornerstone of non-destructive examination in pressure vessels, pipelines, structural steel, and engineered assemblies. X-rays penetrate weld joints to reveal internal discontinuities that surface inspection cannot detect.

Common Weld Defects Visible on X-Ray

• Lack of penetration: Incomplete root fusion weakens the joint.
• Slag inclusions: Non-metallic material trapped in the weld metal.
• Porosity: Gas pockets from contamination or improper shielding.
• Cracks: Linear indications requiring immediate rejection.
• Undercut and overlap: Geometric defects affecting stress concentration.

Standards and Qualification

Many industries reference ISO, ASME, AWS, and EN standards for weld RT acceptance levels. Qualified personnel interpret images according to agreed sensitivity, IQI placement, and density requirements. Digital radiography is increasingly accepted when image quality and archiving meet code requirements.

Equipment Considerations

Industrial X-ray NDT systems for weld inspection must provide adequate penetration for material thickness, stable imaging, and ergonomic operation for field or workshop use. Portable and cabinet systems each serve different site constraints.

Micxy industrial NDT X-ray inspection systems support weld and casting applications with digital imaging and enhanced defect visibility. Contact us for specifications matched to your material thickness and production environment.
