Nondestructive Evaluation (NDE) Roadmap Steel: Fabrication Quality Assurance (QA)
For decades, nondestructive evaluation (NDE) has been an essential part of the extraordinary quality and performance achieved in modern steel bridges. Steel bridges have evolved with the use of new materials and fabrication practices, but the NDE methodologies deployed have generally remained the same. The goal of this umbrella topic is to capitalize on the many opportunities to improve fabrication practices with new and improved NDE for measurement and inspection.
