Arc Welding Control

This book examines the new developments currently at the forefront of modern arc welding. It is divided into five main parts, with the first part giving an account of the dynamic behaviour of the arc welding process, its power sources and its effect on the technology of welding. Part 2 then goes on to describe ways of controlling the welding arc through modern electronics, covering unique and original methods. The third part of the book looks at the prospects of the arc sensor for automatic seam tracking in arc welding, and establishes the first mathematical model of the sensor on the basis of control theory. Part 4 describes an original new method for measuring the welding temperature field using the image colorimetric method, and Part 5 gives a detailed account of the recognition method of 3-dimensional weld grooves. Modern arc welding is essential reading for researchers, academics, students, technicians, engineers and other professionals currently involved in welding automation.
