Real-time operational control in information management system for flash-butt welding of rails
Journal Title: Mining – Informatics, Automation and Electrical Engineering - Year 2017, Vol 529, Issue 1
Abstract
Operational control of welding quality is the fundamental element of the entire rail manufacturing process. In practice, real-time systems are used for this purpose. This article features a new method that makes use of fuzzy logic to analyze the data from mechanical tests and from the ultrasound inspection of connections.
