Engineering Fundamentals by Roger L. Timings

Book description :
Engineering Fundamentals by Roger L. Timing book is designed to meet the latest course requirements for engineers and brings together the essential material from Roger Timings' previous engineering texts: Fundamentals of Mechanical Engineering, Fundamentals of Engineering, Basic Engineering Technology and General Engineering. A highly readable book is supported by numerous illustrations, learning objectives and exercises at the end of each chapter, making Engineering Fundamentals a complete student-focused course that is ideal for classroom, workshop and independent study.

Book Description :

Welding Metallurgy by Sindo Kou book presents the fundamental aspects of fusion welding for students and serves as a handy reference for practising engineers and research workers involved with the welding of engineering alloys. This book deals with the metallurgy of welding, complementing existing welding handbooks and manuals, which tend to emphasise procedures for welding various materials. Book examines the thermal, chemical and mechanical aspects of welding; the metallurgical aspects of welding in three different regions of the weld the fusion, the partially-melted, and the heat affected zones and the micro structure and properties of the weld. Outlines the difficulties in producing sound welds and practical approaches to overcome them. Also covers several important alloy systems and their representative heat affected zone phenomena.
