Manufacturers increasingly rely on X-ray NDT to protect quality at scale. The choice between online (in-line) and offline inspection depends on production volume, part handling, defect risk, and budget. Both approaches use the same radiographic principles but differ in integration and workflow.

Offline X-Ray Inspection

Offline systems—such as cabinet X-ray machines and trolley scanners—inspect batches of parts in a dedicated QC area. Operators load parts manually or with simple fixtures. This approach suits low to medium volumes, prototype development, and applications requiring flexible angles or longer exposure times.

Advantages: Lower initial investment, easier relocation, suitable for varied part sizes.

Online (In-Line) X-Ray Inspection

Online systems integrate with conveyors, robots, or automated transfer lines to inspect every part at production speed. Micxy fully automatic on-line inspection X-ray scanners are designed for continuous quality control in high-volume casting and assembly lines.

Advantages: 100% inspection, reduced labor, immediate rejection of non-conforming parts, data traceability.

Decision Checklist

• Production volume above 10,000 parts/day? Consider online inspection.
• High safety or regulatory requirements? Online 100% inspection reduces risk.
• Many product variants? Offline systems may offer more setup flexibility.
• Limited floor space? Trolley cabinet scanners bridge mobility and performance.
