Low Transformation Temperature Welding Materials

This valuable reference for advanced students and practicing engineers provides a comprehensive overview of low transformation temperature (LTT) welding materials, detailing their design, properties, and weldability, and demonstrating their applications in preventing fatigue and improving corrosion performance in welded structures. Through this book, readers will gain a comprehensive understanding of how LTT actively controls welding residual stress to improve the fatigue life of welded structures and raise corrosion resistance. This book first provides a review of LTT welding materials, addressing the design of chemical compositions for LTT welding materials, the properties and weldability of LTT welding materials, compressive residual stress, and stress concentration, while providing practical application examples of LTT welding materials for preventing fatigue cracking. The authors provide experimental and numerically simulated data, photos, graphs, and tables to illustrate the information within this book and facilitate readers’ understanding. Last, this book discusses practical applications such as the successful prevention of fatigue cracks at the toe of fillet welds (such as boxed fillet welds in ship structures) and surface coating using wire-arc additive manufacturing to improve corrosion performance. These application descriptions are supported by an appendix that supplies digital data of LTT material properties and finite element mesh data for butt and fillet welds. This practical information will allow readers to apply this knowledge in real-world scenarios and also develop and extend the number of applications for LTT welding materials, contributing to improved corrosion performance in welded structures. Upper undergraduate and postgraduate students will find this a valuable resource for their learning as it provides additional information to supplement course materials. Practitioners will also benefit from the practical information including simulation and real-world data that will benefit their daily work.
