Double Wall Double Image (DWDI) technique in X-ray radiography
Double wall double image (DWDI) technique is frequently used for inspecting the quality of small welded steel pipes in radiography. This paper trends to apply DWDI technique to inspect the quality of a welded steel pipe of 60mm diameter. This result is based on radiographic standards and acceptance limits of ASTM (USA) and DIN (Germany).
