Welding Inspection System

Abstract

This Project aims at building an automated welding system that can track a weld seam, calculate its area and depth and accordingly do the welding and also consider to keep the defects to a minimum so that better quality of weld can be given as output. It consists of a laser sensor that illuminates the weld seam so that the CCD/CMOS camera used can get the image of the weld seam. Then this image is transferred to MATLAB for image processing where the image is converted to grey scale and the grey scale image is then divided into two parts first part consists of the seam section which is colored grey and have red dots and other sections is considered as white section which don’t have any utilization till the welding starts. After the image processing the part is carried to the welding section where the welding can be done with the help of the data abstracted from the above methods and then it minimizes the defect of welding and produces the output.
