The Study of Field Application of Digital Radiography Testing for Power Plant Weldments

Abstract:

Since Power Plant has tens of thousands welded parts in its structures, the quality on the welded parts are always a key factor for ensuring the reliability of the structures. Film based Radiography Test (hereinafter called “FRT”) is a generally accepted solution in inspecting the welded structure. However, the RT demands complex workflow, high cost, hazardous waste disposal, and etc…. In an effort to get over such shortcomings from FRT and present alternative inspection tools, this study was intended to evaluate a Digital Radiography Test (hereinafter called “DRT”). In this study, the evaluation were focused on if a DRT is applicable to the inspection of Welded structure in Power Plants, and what benefits can be generated in a use of DRT.
