DOWNLOAD EBOOK →This book is chiefly concerned with the conventional fusion welding processes and their problems and will be of value to practical welding engineers, inspectors and metallurgists. The author also has inmind the needs of those concerned with design and specification, recognising the importance of dealing with problems at the design stage.

DOWNLOAD EBOOK →This book describes the fundamental metallurgical principles that control microstructure and properties of welded stainless steels. It also serves as a practical "how to" guide that allows engineers to select the proper alloys, filler metals, heat treatments, and welding conditions to insure that failures are avoided during fabrication and service.

DOWNLOAD EBOOK →When considering the operational performance of stainless steel weldments the most important points to consider are corrosion resistance, weld metal mechanical properties and the integrity ofthe weldedjoint. Mechanical and corrosion resistance properties are greatly influenced by the metallurgical processes that occur during welding or during heat treatment of welded components. This book is aimed, there fore, at providing information on the metallurgical problems that may be encountered during stainless steel welding. In this way we aim to help overcome a certain degree of insecurity that is often encountered in welding shops engaged in the welding of stainless steels and is often the cause of welding problems which may in some instances lead to the premature failure of the welded component. The metallurgical processes that occur during the welding of stainless steel are of a highly intricate nature. The present book focuses in particular on the signif icance of constitution diagrams, on the processes occurring during the solidification of weld metal and on the recrystallization and precipitation phenomena which take place in the area of the welds. There are specific chapters covering the hot cracking resistance during welding and the practical welding of a number of different stainless steel grades. In addition, recommendations are given as to the most suitable procedures to be followed in order to obtain maximum corrosion resistance and mechanical properties from the weldments.

DOWNLOAD EBOOK →Describes the weldability aspects of structural materials used in a wide variety of engineering structures, including steels, stainless steels, Ni-base alloys, and Al-base alloys Welding Metallurgy and Weldability describes weld failure mechanisms associated with either fabrication or service, and failure mechanisms related to microstructure of the weldment. Weldability issues are divided into fabrication and service related failures; early chapters address hot cracking, warm (solid-state) cracking, and cold cracking that occur during initial fabrication, or repair. Guidance on failure analysis is also provided, along with examples of SEM fractography that will aid in determining failure mechanisms. Welding Metallurgy and Weldability examines a number of weldability testing techniques that can be used to quantify susceptibility to various forms of weld cracking. Describes the mechanisms of weldability along with methods to improve weldability Includes an introduction to weldability testing and techniques, including strain-to-fracture and Varestraint tests Chapters are illustrated with practical examples based on 30 plus years of experience in the field Illustrating the weldability aspects of structural materials used in a wide variety of engineering structures, Welding Metallurgy and Weldability provides engineers and students with the information needed to understand the basic concepts of welding metallurgy and to interpret the failures in welded components.

DOWNLOAD EBOOK →The existing possibilities of steelmaking imply that ultra low sulfur contents can be obtained. The weldability of these steels had not yet been clearly defined as good or not. In this study the welding behavior has been determined both for normalized steels, and quenched and tempered steels. Results concern underbead hardness in the heat affected zone (HAZ) and critical preheat temperature determined by the implant test. Ultra low sulfur steels appear to present a significant improvement in weldability. The underbead hardness is not affected by a sulfur content decrease. The preheat temperature is the same for different stress directions (that is, longitudinal and short transverse) only for steels with a sulfur content lower than about 15/20 ppm. The influence of the weld metal's hydrogen content on cold cracking prevention is reduced with ultra low sulfur steels.

DOWNLOAD EBOOK →Creep-resistant steels are widely used in the petroleum, chemical and power generation industries. Creep-resistant steels must be reliable over very long periods of time at high temperatures and in severe environments. Understanding and improving long-term creep strength is essential for safe operation of plant and equipment. This book provides an authoritative summary of key research in this important area.The first part of the book describes the specifications and manufacture of creep-resistant steels. Part two covers the behaviour of creep-resistant steels and methods for strengthening them. The final group of chapters analyses applications in such areas as turbines and nuclear reactors.With its distinguished editors and international team of contributors, Creep-resistant steels is a valuable reference for the power generation, petrochemical and other industries which use high strength steels at elevated temperatures. Describes the specifications and manufacture of creep-resistant steels Strengthening methods are discussed in detail Different applications are analysed including turbines and nuclear reactors
