Surface-Critical Defects Analysis in Hot-Rolled Long Products, Wire Rod and Bars With Eddy Current and Artificial Vision Testing

摘要

The long products manufacturing market is evolving faster than ever. Customers demand more and more quality and conventional equipment is reaching its limits. In the age of internet of things, big data, artificial intelligence and industry 4.0 customer demands intelligent sensors, and intelligent equipment that can communicate directly with other devices to minimize human operations. The NDT (nondestructive testing) procedures have often the privilege to be located at the end of the production lines so they can get a lot of information that properly distributed can offer new levels of knowledge that will be key for processes and products improvement. But now the priority is to identify critical defects with a high accuracy, and the further step will be the analysis of the causes and fixing them. Integration of technologies represents a unique opportunity that can only be useful by using an analysis methodology.
