There are, therefore, often several ways to specify a given weld. Part A of this standard covers welding symbols, Part B deals with brazing symbols, and Part C describes symbols for specifying nondestructive examinations.Īlthough the basic symbol system is uniform, there is a need for some flexibility, as specific circumstances differ from one shop to another and field operations may involve entirely different situations. ![]() The current American standard for welding symbols was originated by the American Welding Society and approved by the American National Standards Institute as ANSI/AWS A2.4:2012, Standard Symbols for Welding, Brazing and Nondestructive Examination. The need for consistency in both the application of welding symbols to engineering drawings, and the accurate interpretation by personnel directly involved in manufacturing or construction, led to the development of a standard for these activities. Welding symbols, when properly applied to drawings and, as importantly, when correctly interpreted, offer a potentially convenient way of controlling the welding of a particular joint. Summary: The following article is a part of National Board Classic Series and it was published in the National Board BULLETIN.
