Weld Distortion Detection by Non-contact Dimension Measurement Based on Image Processing

Aiming towards the problem of traditional weld distortion measurement method that they are less efficient and can cause errors in measurement. Study of the non-contact measurement system for weld distortion is mentioned in this paper. The hardware part of non-contact dimension system consists of a camera, lens and welded object. Processing is done on the images of the welded object. In order to improve detection, various algorithms are mentioned. Advantages of the mentioned method are that it avoids human mistakes, decreases the cost, higher the speed of control line and coincidence with new production standards. It improves the efficiency of distortion measurement system and gives better results. This paper describes the study of various methods of weld distortion measurement.
