Automatic Image Processing For Welding Inspection
نویسندگان
چکیده
This paper deals with the automatic detection of defects within various welding. The authors propose a method based on taking an X-ray image of the welding and then applying various image processing algorithms for the detection of possible defects. This method has a significant improvement in the detection success ratio compared to classical detection techniques (by using human operators). Key-Words: defect detection, industrial inspection of welding, image processing

متن کاملAutomatic Detection and Localization of Surface Cracks in Continuously Cast Hot Steel Slabs Using Digital Image Analysis Techniques
Quality inspection is an indispensable part of modern industrial manufacturing. Steel as a major industry requires constant surveillance and supervision through its various stages of production. Continuous casting is a critical step in the steel manufacturing process in which molten steel is solidified into a semi-finished product called slab. Once the slab is released from the casting unit, th...

The present paper proposes a new concept of image processing method based on vector representation for visual inspection test. The method was applied to detect defects and extract their profiles from digital 2D image of welded rough surface of the structures aiming at the development of automated visual inspection system. The potential availability of the new technique based on vector represent...
متن کاملAUTOMATIC X-RAY IMAGE CHARACTERISATION for NON- DESTRUCTIVE EVALUATION
In this paper, firstly we introduce an automatic welding defect inspection system for X-ray image evaluation, then, a novel image segmentation approach is proposed. In this approach, we first apply an adaptive morphological filter (AMF) with an appropriate structuring element to remove noise and most of the background image which is useless for defect identification. Secondly, edges were derive...
