Guidedwave Mission Statement
To become the leading ultrasonic guided wave innovations company
Market Niche
“Theoretically-driven” sensor design and software development combined with unprecedented vast experience in ultrasonic guided waves
Guided Waves vs.
Bulk Waves
Natural Waveguide Examples
• Plates (ship hull, aircraft skin)
• Rods (cylindrical, square, rail, etc.)
• Hollow cylinder (pipes, tubing)
• Multi-layer structures
• Curved or flat surfaces on a half-space
• Layer or multiple layers on a half-space
• An interface
Aircraft Skins
Pipelines
Storage Tanks
Principal Benefits of Guided Waves • 100% coverage throughout the thickness of the structure.
• Inspection over long distances from a single probe position.
• Ability to inspect hidden and inaccessible regions of structures and structures under water, coatings, insulations, and concrete.
• Cost effectiveness because of inspection simplicity and speed.
Common Uses • Pipe inspection and monitoring
• Plate inspection and monitoring
• Delamination detection
Long-Range GW Pipeline Inspection Technology (U.S. Patents 11/948,383 and 13/298,758)
