WELDING AND METAL FABRICATION employs a unique hands-on, project-based learning strategy to teach welding skills effectively and keep students highly motivated. This groundbreaking new text connects each welding technique to a useful and creative take-home project, making exercises both practical and personal for students'and avoiding the tedium of traditional, repetitive welding practices. To further enhance the learning process, every welding project includes a set of prints with specifications, like those used in production fabrication shops. This full-featured approach to skill-building reflects the reality of professional welding, where following prints and instructions precisely and laying out, cutting out, and assembling weldment accurately are just as essential as high-quality welding. The included projects are small to conserve materials during the learning process, but detailed instructions and abundant photos and illustrations guide students through a wide range of fabrication skills. Key steps and techniques within the small projects are also linked to larger projects presented at the end of each chapter, enabling students to apply what they have learned by fabricating and welding something more substantial. This thorough, reader-friendly text also covers relevant academics, such as shop math and measurement, and prepares students for real-world success by having them document their time and materials for each project and prepare a detailed invoice.

 This book is a comprehensive presentation of the fundamental concepts and applications of metal fabrication technology. Designed primarily for undergraduate and postgraduate students of mechanical engineering and production engineering, the book will also be useful for students of engineering diploma programmes in the above fields and certificate courses in metal fabrication and erection, as well as for practising engineers and consultants involved in welding, fabrication, erection, production planning, testing and design.

The initial chapters of the book provide an overview of the metal fabrication industry, as well as an exhaustive discussion of the properties of the various engineering materials, heat treatment processes, and frame analysis. The focus then shifts to production planning and control, production line design, as well as drawing, marking and layout. The ensuing chapters explain elaborately the various metal cutting processes, metal forming methods, and manufacturing processes. Assembly and erection, joining and welding, fault analysis and inspection, and metal finishing are covered subsequently. The various systematic guidelines for erection as well as the different prohibited welding methods and welding defects are elucidated. The final chapter of the book is devoted to health and safety issues relevant to fabrication and erection.

The book contains numerous illustrations that enable the students to gain a thorough understanding of the subject matter. The review questions at the end of each chapter help to test their comprehension of the underlying concepts.
The revised and updated second edition of this book gives an in-depth presentation of the basic principles and operational procedures of general manufacturing processes. It aims at assisting the students in developing an understanding of the important and often complex interrelationship among various technical and economical factors involved in manufacturing. The book begins with a discussion on material properties while laying emphasis on the influence of materials and processing parameters in understanding manufacturing processes and operations. This is followed by a detailed description of various manufacturing processes commonly used in the industry. With several revisions and the addition of four new chapters, the new edition also includes a detailed discussion on mechanics of metal cutting, features and working of machine tools, design of molds and gating systems for proper filling and cooling of castings. Besides, the new edition provides the basics of solid-state welding processes, weldability, heat in welding, residual stresses and testing of weldments and also of non-conventional machining methods, automation and transfer machining, machining centres, robotics, manufacturing of gears, threads and jigs and fixtures. The book is intended for undergraduate students of mechanical engineering, production engineering and industrial engineering. The diploma students and those preparing for AMIE, Indian Engineering Services and other competitive examinations will also find the book highly useful. New to This Edition : Includes four new chapters Non-conventional Machining Methods; Automation: Transfer Machining, Machining Centres and Robotics; Manufacturing Gears and Threads; and Jigs and Fixtures to meet the course requirements. Offers a good number of worked-out examples to help the students in mastering the concepts of the various manufacturing processes. Provides objective-type questions drawn from various competitive examinations such as Indian Engineering Services and GATE.
From the world’s #1 body language expert* comes the essential book for decoding human behavior

Joe Navarro has spent a lifetime observing others. For 25 years, as a Special Agent for the FBI, he conducted and supervised interrogations of spies and other dangerous criminals, honing his mastery of nonverbal communication. After retiring from the bureau, he has become a sought-after public speaker and consultant, and an internationally bestselling author. Now, a decade after his groundbreaking book What Every BODY is Saying, Navarro returns with his most ambitious work yet. The Dictionary of Body Language is a pioneering “field guide” to nonverbal communication, describing and explaining the more than 400 behaviors that will allow you to gauge anyone’s true intentions.

Moving from the head down to the feet, Navarro reveals the hidden meanings behind the many conscious and subconscious things we do. Readers will learn how to tell a person’s actual feelings from subtle changes in their pupils; the lip behaviors that betray concerns or hidden information; the many different varieties of arm posturing, and what each one means; how the position of our thumbs when we stand akimbo reflects our mental state; and many other fascinating insights to help you both read others and change their perceptions of you.

Readers will turn to The Dictionary Body Language again and again—a body language bible for anyone looking to understand what their boss really means, interpret whether a potential romantic partner is interested or not, and learn how to put themselves forward in the most favorable light.
