Non-Destructive Testing

Non-destructive testing (NDT) finds flaws and measures material condition without damaging the part. The range covers ultrasonic thickness gauges and flaw detectors, magnetic particle yokes and consumables, dye penetrant systems, eddy current instruments, radiographic film viewers, hardness testers, coating and surface gauges, and visual inspection tools.

Typical applications

• Weld inspection and fabrication quality control
• Corrosion and wall-thickness surveys on pipes, tanks and vessels
• Crack detection on castings, forgings and machined parts
• In-service and shutdown maintenance inspection
• Training and procedure checks with reference blocks and flawed specimens

Choosing a method

Start with the flaw or property you need to find, the material, and whether the flaw is at the surface or inside the part. Surface cracks in magnetic steels suit magnetic particle testing. Surface-breaking flaws in non-magnetic metals suit dye penetrant. Internal flaws and wall thickness suit ultrasonic testing.
