Foreword

Designing Weldments by Ramesh Singh, addresses the importance of how properly designed welds in a structure can change the approach to its design, leading to greater structural integrity and potentially reduced cost. This book seeks to strengthen frequently neglected elements of design engineering involving structural load-bearing members of various metals, but particularly those of steel, and aluminum manufacture. Ramesh’s real-world experiences have led him to conclude that many engineers possess only a basic education about the welding. Consequently, many are ill-equipped with sufficient understanding of how welded structures respond to loading versus, for example, a wrought steel member in a structure. How do the presence of welds within the structure change stress types and concentrations, thereby having significant impact on the long term integrity of the structure? How can the designer take strategic advantage of welding technologies to strengthen the structural design while also reducing its weight and finished cost. Finally, this book also addresses the differences between a cast structure and a welded structure, and what factors need to be addressed when converting a cast structure design to a welded structure design, as might be done for a machine component.

The importance of the type of weld joint preparation, for full penetration, or partial penetration, butt weld or fillet weld, or a combination of fillet and groove welds is addressed in detail. The book also provides an introduction to various welding processes, materials of construction, and their classifications.

I have worked professionally with Ramesh for more than two decades. He is passionate about his work in metallurgy, corrosion, fabrication and welding, which spans more than half a century and multiple industries. Unlike many whose background is primarily academic; his knowledge has been acquired through practical experience in a variety of settings around the globe. An avid long distance bicycle rider, and dedicated marathon runner, Ramesh brings that same level of devotion and commitment to his profession.

Designing Weldments will be an important resource and reference tool for structural designers and engineers. The book is replete with illustrations, tables and figures to bring visual clarity and substance to the technical nomenclature necessary for such a complex subject.
