Supersonic Inspection
 

Ultrasonic Inspection

Ultrasonic inspection at BESSEY Präzisionsstahl GmbH is performed as an automatic continuous process, using phased-array technology. This enables the use of various ultrasonic testing techniques, as defined in EN 10308. This includes grid-pattern examination for sq./oct. and for hex. sections as well as a 100% volumetric inspection of the core area, either with or without inspection of the edge zone. Such testing is suited to all the types of steel we offer, from unalloyed structural steel to highly-alloyed stainless and acid-resistant grades.

Testable area Test type Max.  registration limit*
Ø 10 - 43 mm 100% volumetric inspection uninspected edge zone of 2-3 mm FBH 0.7 mm
Ø 10 - 36 mm 100% full volumetric inspection with inspected edge zone FBH 0.7 mm
hexagonal 10 - 30 mm Grid-pattern examination uninspected edge zone of 2-3 mm FBH 1.0 mm
octagonal 10 - 30 mm Grid-pattern examination uninspected edge zone of 2-3 mm FBH 1.5 mm
square 10 - 22 mm Grid-pattern examination uninspected edge zone of 2-3 mm FBH 2.0 mm

- FBH-values are dependent upon the steelgrade
- Uninspected bar ends (50mm on both sides)
- Inspection for min. defect length of 10 mm possible

Other dimensions of FBH-values are available on request
