This specification prescribes the composition, dimensions, soundness, and properties of weld metal from more than 30 classifications of nickel and nickel-alloy covered electrodes. Major topics include general requirements, testing, manufacturing, identification, and packaging. A guide to using the specification is included in an annex.

This specification makes use of both U.S. Customary Units and the International System of Units (SI). Since these are not equivalent, each system must be used independently of the other.

The American Welding Society is the largest organization in the world dedicated to advancing the science, technology, and application of welding and allied processes, including joining, brazing, soldering, cutting, and thermal spraying. Headquartered in Miami, Florida, USA, AWS serves almost 50,000 members in the United States and around the world.

In 2005, the FABTECH INTERNATIONAL & AWS Welding Show—the largest welding, metal forming, & fabricating event—will take place November 13-November 16, 2005, in Chicago, IL, USA. www.aws.org/expo For more information on AWS programs and publications, visit the Society's web site, www.aws.org.
