AWS A2.4:2007, Standard Symbols for Welding, Brazing, and Nondestructive Examination Now Available

Miami, FL, June 28, 2007 – In today’s environment, where quality control and manufacturing efficiency is paramount, it is increasingly critical that joining processes and examination methods are conveyed in a consistent manner. To maintain this uniformity in communication, the American Welding Society (AWS) today announced their newly published standard, AWS A2.4:2007, Standard Symbols for Welding, Brazing, and Nondestructive Examination. AWS is the world’s largest nonprofit organization dedicated to advancing the science, technology and application of welding.

This American National Standards Institute (ANSI)-approved standard establishes a method for specifying certain welding, brazing, and nondestructive examination information by means of symbols.  These symbols are intended to be used to facilitate a standard dialogue as it pertains to the areas of joining and examination, particularly among design, fabrication and inspection personnel, to help accelerate and ease the production process. In addition, the standard also provides a means for placing welding, brazing, and nondestructive examination information on drawings. Detailed information and examples are provided for the construction and interpretation of these symbols. 

This seventh edition of the standard represents the culmination of many years of work by the AWS A2 Committee on Definitions and Symbols. It was developed in response to industry demand for standard symbols to streamline communication between fabrication, design and inspection personnel as joining technology is increasingly advancing and expanding.

The standard contains 138 pages, and is priced at $144 for non-members or $108 for AWS members. AWS publications may be purchased in the United States and Canada by calling toll-free 888-WELDING (888-935-3464); elsewhere, call 305-824-1177, fax to 305-826-6195, or order online at http://www.awspubs.com. A catalog listing all AWS standards and other documents is available for download from the AWS web site, www.aws.org/catalogs.

The American Welding Society (AWS) was founded in 1919 as a multifaceted, nonprofit organization with a mission to advance the science, technology and application of welding and allied joining and cutting processes, including brazing, soldering, and thermal spraying. Headquartered in Miami, Florida, and led by a volunteer organization of officers and directors, AWS serves more than 50,000 members worldwide and is composed of 22 districts with 250 sections and student chapters.
