ViDi Welding Seam Inspection


  • Welding seams exhibit a large variety of shapes and features which can hardly be described by classical means
  • Normal and expected variations in the welding process and material need to be tolerated
  • The highly reflective and irregular metallic surface renders as a complex texture in the image

Cognex ViDiWith ViDi Suite, the automated optical inspection of welding seams is now extremely simple. The software algorithm trains itself on a set of known good samples which are presented in front of the camera and creates its reference model.

With its powerful statistical algorithm, ViDi Suite can train on a large amount of images representing all the process and image variations. Once this training phase is completed, the inspection is ready to go. Defective welding seams can be reliably identified and reported.
