This study aims to elevate the quality control standards in steel bridge fabrication by expanding the available testing options beyond conventional ultrasonic and radiographic inspection. The research evaluates the feasibility and effectiveness of phased array ultrasonic testing, an innovative technology, for its potential integration into bridge weld nondestructive inspection processes as an efficient alternative to radiographic testing.

This report is tailored for professionals involved in or overseeing steel bridge fabrication shop inspection, encompassing bridge owners, their quality control representatives, and third-party inspection firms. The findings and recommendations of this study empower these stakeholders to make informed decisions and embrace advanced inspection methodologies to enhance the overall quality control of steel bridge fabrication projects.
