Ultrasonic inspection system for real-time weld quality assessment in roof membranes
A novel ultrasonic inspection system using a wheel probe for real-time assessment of roof membrane weld quality. It provides cost-effective, in situ evaluation and real-time feedback, enhancing welding accuracy and reducing defects.
Overview
The ultrasonic inspection system is designed to enhance the quality assurance in roof membrane welding by providing real-time feedback on weld integrity. This innovative technique uses ultrasound to detect the quality of the weld by measuring reflections at the bond line and the bottom surface. The system is cost-effective, integrates easily into existing welding equipment, and offers a direct mechanical interrogation of weld quality, unlike other non-destructive evaluation (NDE) methods that rely on indirect thermal assessments.
Technical specifications
Key features:
- Utilizes a wheel probe to transmit ultrasound through overlapping membrane layers
- Differentiates between high-quality and poor welds based on reflection strength
- Provides real-time feedback, allowing for immediate adjustments
- Easily integrates into existing welding equipment
Technical process:
- Ultrasound is transmitted through membrane layers
- High-quality welds show weak reflection at the bond line and strong reflection from the bottom surface
- Poor welds exhibit strong reflection at the bond line
- Results are analyzed in real-time to provide immediate feedback
Technology readiness level
This ultrasonic inspection system is currently at Technology Readiness Level 4. It has been validated through feasibility studies and is ready for further development and testing in realistic welding conditions. Future validation plans include the development of a wheel probe prototype and performance validation through destructive testing.
