New Technology for NDT Weld Inspections – Phased Arrays and Diffraction Sizing

Abstract:

This article describes new techniques and technology for inspecting welds using automated ultrasonics. The prime new technology is phased arrays, while the new techniques are Time-of-Flight Diffraction and S-scan back diffraction. The relationship of phased arrays with North American codes is briefly given, along with an inspection result, comparing radiography, pulse-echo phased arrays and TOFD.
