RESEARCH ARTICLE A REVIEW ON AUTOMATED INSPECTION AND EVALUATION SYSTEM OF WELD DEFECT DETECTION ON RADIOGRAPHIC IMAGE

This paper discuss on overview development of automated detection system to inspect and evaluate the existence of weld defect on radiographic image. In general, there are four stages in development of automation analysis: image digitization, image processing, feature extractions and classification. The purpose of the automation process is to improve the inspection results given by radiography inspector by reducing the subjectivity, inconsistency of analysis results while reducing the analysis time. In order to digitized xray film that contain defect, appropriate scanner is used. Then, the digitized image can be manipulated digitally using image processing techniques for further analysis. The used of x-ray film is still popular in industries because it is quite expensive to convert to new technology of digital radiography. This paper provides a comprehensive review in developing automated weld defect detection to assist radiographer for accurate weld defect analysis.
