A unique and practical introduction to the basics of Gas Metal Arc Welding is found in this book. Written for beginners, the classroom book presents concepts in digestible chunks and reinforces the content with Knowledge Checks interspersed throughout, a wealth of chapter-end review questions, and a variety of welding exercises. Safety is emphasized throughout, especially through Arc Alert feature boxes. The accompanying lab manual (available separately) offers the student a variety of additional review exercises, especially focusing on math, measuring, and problem solving.CLASSROOM MANUAL: PREFACE.
