The welding industry is in the process of change and under pressure. New processes and new materials are being introduced in the wake of increasingly tough competition.
In this book, Richard Boekholt, a senior welding consultant with vast experience and a uniquely international outlook, has compiled and summarised international practice within the field of welding developed from a European Union study 'Working Life 2000. The Welding Industry in Technological Change: a Human Resource Perspective'.
The book looks at the impact of automation and explains that, while some people may feel that the use of robotics and computers will threaten welders' jobs, in fact robots and computers will help welders, not replace them. At present welders are in demand and companies are faced with difficulties in recruiting and retaining good staff. It is through improved working conditions, which are presently often environmentally unsafe with workers exposed to smoke, noise, vibration and heavy physical labour, that companies can attract and keep workers.
The book emphasises the importance of managing human resources and looks at new ways of doing this. A recognition of the importance of managing human resources and looks at new ways of doing this. A recognition of the importance of training, of instructors as well as workers, will be essential to achieve the dedicated, motivated and flexible workforce necessary to work with the new technologies of the 21st century.

Based on the European Welding Engineer (EWF) syllabus Part 3 - Construction and Design, this book provides a clear, highly illustrated and concise explanation of how welded joints and structures are designed and of the constraints which welding may impose on the design. It is therefore of value both to the welding engineer and the design engineer
Many engineers coming into the profession of welding engineering lack a background in design and construction of welded structures and plant. This book has been written with such engineers very much in mind.
The safe performance of a structure relies on materials and methods of fabrication which can respond to the explicit or implicit design requirements. It is essential that the welding engineer has the opportunity of making his specialist input to the design process, and an understanding of the basis of the design will help that contribution to be most effective. It is also important that the practising design engineer acquires a basic knowledge of the relevant aspects of welding to be able to execute satisfactory designs and, equally important, to know when to seek the input of a qualified welding engineer.
Designed for both students and practising engineers in welding and design, the book will also be of great value to civil, structural, mechanical and plant engineers. There is also much that will interest test houses, welding equipment and consumable manufacturers, classification societies and steel companies.

These recommendations present general methods for the assessment of fatigue damage in welded components, which may affect the limit states of a structure, such as ultimate limit state and serviceability limited state. Fatigue resistance data is given for welded components made of wrought or extruded products of ferritic/pearlitic or banitic structural steels up to fy = 700 Mpa and of aluminium alloys commonly used for welded structures.
