Six Technical Contributions from GWA
This year, GWA is making a significant technical contribution to the conference, with five technical papers accompanied by video presentations and one additional video presentation-only contribution.
Our six contributions focus on Guided Wave Testing (GWT), addressing important topics ranging from inspection fundamentals and physics-based principles to reporting transparency, inspection reliability, and future developments in the technology.
Here is an overview of our contributions:
This paper examines guided wave testing from its fundamental identity as ultrasonic testing operating at low frequencies. By establishing a physics-based framework, it addresses the principles underlying reliable pipeline inspection, defect characterization, and inspection transparency.
This paper explores how reporting principles commonly used in conventional ultrasonic testing can be applied to long-range ultrasonic inspection. The objective is to improve transparency, consistency, and clarity in GWT reporting, making inspection results more understandable and meaningful to end users.
Multi-frequency operation offers additional opportunities to improve defect detection and characterization in guided wave inspection. This paper examines how multi-frequency techniques can enhance probability of detection (POD) and defect sizing capabilities in GWT.
Accurate terminology and clear reporting are essential for reliable inspection communication. This paper addresses the distinction between reflection coefficient and reflectivity, explaining why the appropriate terminology matters when presenting and interpreting GWT results.
5. Minimum Technical Requirements for Reliable Guided Wave Testing of Pipelines
Reliable inspection starts with establishing appropriate technical requirements. This paper addresses the minimum technical requirements necessary for consistent and reliable guided wave testing of pipelines, with an emphasis on inspection consistency and reporting.
6. The Future of Guided Wave Testing — A Four-Part Framework for Reliable Inspection
This presentation introduces a four-part framework for the future development of guided wave testing. It explores a structured approach to improving inspection reliability and pipeline integrity, highlighting the importance of a comprehensive framework rather than relying on individual inspection techniques alone.
Supporting the Advancement of NDT
At GWA, we believe that advancing NDT technology requires more than developing inspection systems. It also requires sharing knowledge, challenging established assumptions, improving inspection practices, and making technical results more transparent and useful to the industry.
Our six contributions to NDTonline 2026 reflect this commitment. From fundamental inspection principles to practical reporting requirements and future frameworks, our goal is to help move guided wave testing toward greater technical consistency, reliability, and industry-wide understanding.
We appreciate the opportunity to support NDTonline 2026 as a sponsor and look forward to sharing our work with fellow NDT professionals around the world.
We look forward to connecting with you at NDTonline 2026!
