Content Description

Chapter 2 from the Welding Handbook, Ninth Edition, Volume 2, “Welding Processes, Part 1,” has been selected by the AWS Product Development Committee as a service to industry professionals. This chapter covers the principles of operation, introduces the techniques that are applicable to the making of a weld, explains some of the metallurgical dynamics of the shielded metal arc weld, and describes the equipment and materials used in the process. Because they are of essential importance to the process and are definitive to the success of the weld, covered electrodes are discussed in detail. For the convenience of the reader, the text is arranged for easy reference to specific classifications of electrodes. Other topics discussed are welding variables, joint design and preparation, welding techniques, procedures, weld quality, economics and safe practices. References to pertinent standards and specifications are included throughout the chapter and listed in the bibliography at the end of the chapter.
