The first edition of Welding processes handbook established itself as a standard introduction and guide to the main welding technologies and their applications. This new edition has been substantially revised and extended to reflect the latest developments. After an initial introduction, the book first reviews gas welding before discussing the fundamentals of arc welding, including arc physics and power sources. It then discusses the range of arc welding techniques including TIG, plasma, MIG/MAG, MMA and submerged arc welding. Further chapters cover a range of other important welding technologies such as resistance and laser welding, as well as the use of welding techniques for cutting, surface cladding and hardfacing, soldering and brazing. A final group of chapters discuss more general issues such as mechanisation, safety, residual stress and distortion, welding design, costs and quality assurance, as well as the welding of steel and aluminium. The new edition of Welding processes handbook confirms its reputation as a concise, authoritative and practical introduction to welding and its applications for both students and engineers.

The welding of aluminium and its alloys provides a basic understanding of the metallurgical principles involved in the way that alloys achieve their strength and how welding can affect their properties. The book is aimed at engineers with little or no knowledge of metallurgy and perhaps only the briefest acquaintance with welding processes. It is intended as a practical guide for the shop-floor engineer and covers weldability of aluminium alloys, process description, advantages, limitations, proposed weld parameters, health and safety issues, preparation for welding, quality assurance and quality control issues along with problem solving. The book includes sections on parent metal storage and preparation prior to welding. It describes the more frequently encountered processes and has recommendations on welding parameters that may be used as a starting point for the development of a viable welding procedure. Included are hints and tips on how to avoid some of the pitfalls of welding these sometimes problematic materials. The content is both descriptive and qualitative, and the author has avoided the use of mathematical expressions to describe the effects of welding. This book is essential reading for welding engineers, production engineers, production managers, designers and shop-floor supervisors involved in the aluminium fabrication industry.

This edition of Health and safety in welding and allied processes has been extensively revised to take into recent account advances in technology and legislative changes both in the UK and USA. Beginning with a description of the core safety requirements, it goes on to describe the special hazards found in the welding environment – noise, radiation, fume, gases and so on in terms of their effects and the strategies that can be adopted to avoid them. The book takes each major joining technology in turn and discusses the key hazards that are most relevant to each process. There are chapters covering: the common arc and gas welding processes; specialised welding processes; brazing, soldering and thermal spraying; welding and flame spraying of plastics; radiographic inspection; mechanical hazards; noise and vibration; radiation; compressed gases; fume and ventilation; fire and first aid; and welding in situations of increased hazard, such as those requiring special precautions to ensure safe working on vessels contaminated by flammable materials. The aim throughout the book is to explain the hazards clearly and concisely, describe how they arise, and suggest practical methods to achieve safe working. Health and safety in welding and allied processes is an essential resource for welders, their managers and all health and safety practitioners who have welding and related processes taking place in their workplaces. A completely revised new edition of the definitive work on welding health and safety Provides detailed risk analysis for all the major processes Shows how to set up effective workplace systems for risk assessment, first aid and reporting

Friction stir welding (FSW) is a highly important and recently developed joining technology that produces a solid phase bond. It uses a rotating tool to generate frictional heat that causes material of the components to be welded to soften without reaching the melting point and allows the tool to move along the weld line. Plasticized material is transferred from the leading edge to trailing edge of the tool probe, leaving a solid phase bond between the two parts. Friction stir welding: from basics to applications reviews the fundamentals of the process and how it is used in industrial applications. Part one discusses general issues with chapters on topics such as basic process overview, material deformation and joint formation in friction stir welding, inspection and quality control and friction stir welding equipment requirements and machinery descriptions as well as industrial applications of friction stir welding. A chapter giving an outlook on the future of friction stir welding is included in Part one. Part two reviews the variables in friction stir welding including residual stresses in friction stir welding, effects and defects of friction stir welds, modelling thermal properties in friction stir welding and metallurgy and weld performance. With its distinguished editors and international team of contributors, Friction stir welding: from basics to applications is a standard reference for mechanical, welding and materials engineers in the aerospace, automotive, railway, shipbuilding, nuclear and other metal fabrication industries, particularly those that use aluminium alloys. Provides essential information on topics such as basic process overview, materials deformation and joint formation in friction stir welding Inspection and quality control and friction stir welding equipment requirements are discussed as well as industrial applications of friction stir welding Reviews the variables involved in friction stir welding including residual stresses, effects and defects of friction stir welds, modelling thermal properties, metallurgy and weld performance
