, technology, and application of welding
Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material that cools to become a strong joint, with pressure sometimes...

Brazing is a metal-joining process whereby a filler metal is heated above and distributed between two or more close-fitting parts by capillary action. The filler metal is brought slightly above its melting temperature while protected by a suitable atmosphere, usually a flux...

Soldering is a process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, the filler metal having a lower melting point than the workpiece...

, but also conducts events and individual section and district meetings throughout the United States and in international locations. The organization is perhaps best known for its code and certification procedures, which provide industry standards for the welding and joining of metals, plastics and other materials. Through their publications, internet forums, member services, local and national events, educational resources, networking activities, and certification procedures, AWS keeps welding professionals and those interested in materials science up to date with the most current advances and procedures in the industry. As of September 2006, the society contains about 50,000 members, most within the United States.

History of the American Welding Society

The roots of the American Welding Society stretch back to World War I
World War I
World War I , which was predominantly called the World War or the Great War from its occurrence until 1939, and the First World War or World War I thereafter, was a major war centred in Europe that began on 28 July 1914 and lasted until 11 November 1918...

, when the sudden demands of swiftly producing military equipment brought about the need for standardization of the manufacturing industry. President Woodrow Wilson

Thomas Woodrow Wilson was the 28th President of the United States, from 1913 to 1921. A leader of the Progressive Movement, he served as President of Princeton University from 1902 to 1910, and then as the Governor of New Jersey from 1911 to 1913...

By 1919, industry leaders agreed that dependable and objective information on welding was crucial for further U.S. industrial development, and the two organizations merged together to create the American Welding Society.

An immediate need was to create a publication that could objectively cover the scientific advances of the industry, and in 1922, AWS started publishing the Welding Journal. The Welding Journal now appears monthly, and contains peer-reviewed articles on welding and materials science along with industry news and information about society events and members.

AWS also became concerned about welding and safety standards, and began offering certification standards and safety procedures to offer guidance on secure welding techniques and safety procedures. Today, AWS publishes more than 100 codes and procedures detailing welding standards for multiple metals, composite materials, and plastics.

AWS Codes and Specifications

AWS publishes codes on multiple aspects of welding and materials joining. The code books are assigned specific letters and numbers for easy reference, and many welders will refer to a specific code letter/number combination when referring to the code book. Different welding methodologies, inspection methods, and metals are published under different codes. For example, AWS B1.11 explains how to visually examine welds; AWS B2.1-1-004 explains welding carbon steel of thickness range of 18 through 10 gauge with semiautomatic metal gas arc welding; and AWS C2.20/C2.20M explains metalized zinc cathodic protection systems. Some codes also describe the standards used by AWS to certify welders, inspectors, and welding educators. All codes are available in hard copy, and in recent years AWS has started to make most codes available online.

AWS Certification

AWS certifies welders, inspectors, engineers, fabricators, radiographic interpreters, and robotic arc welders. Certification consists of detailed testing procedures. The Radiographic Interpretation Certification, for example, includes a detailed general knowledge exam, a test of specific information from the AWS Code book on radiographic quality and interpretation, and a practical exam testing the individual's ability to read radiographic films. Certification typically needs to be renewed after a period of nine years. AWS requires certification exams to be taken at an AWS accredited testing facility.

AWS Foundation

The AWS Foundation supports welding education through multiple scholarships and awards for students studying welding, welding engineering and materials science at the post secondary and graduate level. Scholarships are both need and merit based.
