This new edition of Welding Essentials retains its original purpose: a book that makes learning welding easy and serves as a reliable quick reference for experienced professionals. It presents essential material in small, easy-to-read, and understandable units and is designed for beginning welders, students, educators, hobbyists, welding inspectors and supervisors, contractors and manufacturers employing welders, and anyone who has an interest in or needs to know about welding. Its unique and comprehensive question-and-answer format will allow you to quickly find the information you need and fully understand it.
Some of the changes in the second edition include: oxygen-acetylene welding and cutting chapters have added information on how to choose the correct size welding nozzles or cutting tips; a chart has been added to better clarify the identification of the gas metal arc welding wires in wire-feeding chapter; non-consumable electrode welding chapter has added information about gas tungsten arc welding electrode properties and their use; survey of the welding processes chapter adds friction stir welding; inspection and discontinuities chapter has improved information about inspection processes and procedures; welding symbols chapter includes more in-depth explanations of each section of the figures; qualification and certification chapter has added information concerning welding procedure specifications and forms; the appendix includes an expanded and improved index.
Welding Essentials continues to address safety hazards and required precautions in detail and provides solutions to common problems for each process. It discusses the difference between constant voltage and constant power supplies and traces the development of welding power supplies from motor-generator sets to transformers to the inverters of today. And it carefully explains step-by-step setup and shutdown procedures, along with why equipment grounding and GFI's are needed and the way in which they work. In fact, no other welding text covers electrical safety as thoroughly as Welding Essentials. Finally, a metallurgy chapter explains how welding heat affects metals' properties and how to minimise its negative effects and provides a clear explanation of hardening, tempering and heat treating steel.
Welding Essentials uses more than 300 illustrations to clarify and explain every topic and it includes a comprehensive glossary in English and Spanish.
