This book was released on 2010-12 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weight reduction is important in the automotive industry. To achieve this, Tailor Welded Blanks (TWB s) are used: body panels consisting of sheets with different thicknesses and/or materials, welded together and stamped into the desired shape. Aluminium TWB s have been introduced only recently. Laser welding is a joining technique that shows high potential to produce the required strong yet deformable welds. In this work various aspects of the laser welding of these thin aluminium sheets are treated, like the development of a control system to ensure full penetration keyhole welding and a camera based monitoring system that allows coaxial in-situ process monitoring. Furthermore several models are presented which help to gain a better understanding the welding behavior. Finally five different laser based welding techniques are compared, among which laser welding with cold wire feeding, twin spot laser welding and laser/GMA hybrid welding.

Available in PDF, EPUB and Kindle. Book excerpt: Welding is a complex process, is increasingly automated, and operates at higher speeds in more difficult environments. Defects also need to be detected as they arise to ensure efficient, high-quality production. All these needs have led to a growing interest in the use of sensors to provide accurate, robust, real-time monitoring where this cannot be achieved by more traditional testing and inspection techniques. This important book reviews the range of monitoring techniques available and their applications. After an introductory chapter, the first part of the book reviews the range of sensor technologies in welding, from arc and optical sensors to infrared and ultrasonic techniques. Part two discusses the monitoring of particular aspects of welding such as weld seams and profiles, the analysis of weld penetration and weld pool surface, as well as monitoring of resistance and laser welding. With its distinguished editor and international team of contributors, Real-time weld process monitoring is a valuable reference to all those concerned with improving the quality of welding and welded components.

Book excerpt: The ability to monitor and control the depth of a laser weld in real-time is critical in many laser welding applications. Consequently, the authors have investigated the use of an optical method to sense weld depth. Welds were generated on kovar samples, using a pulsed Nd:YAG laser. The sensing method uses digital high-speed photography to measure the velocity of the plume of vaporized metal atoms ejected from the metal surface. An energy balance equation is then used to relate the plume velocity to the size of the weld. Numerical solution of the energy balance equation yielded values for weld depth that were within 8% of the actual measured values.
