Welding symbols on drawings

This contemporary book provides an up-to-date review on the application of ISO and AWS standards and a comparison between them. Many thousands of engineering drawings are currently in use, which have symbols and methods of representation from superseded standards. The current European and ISO standards and the American standard are substantially similar, but the ANSI/AWS standard includes some additional symbols and also symbols for non-destructive testing. Although symbols in the different standards are similar, the arrows showing locations of welds are different, these important differences are explained. ISO contains limited information on brazed or soldered joints these are covered in ANSI/AWS. Some examples of the application of welding symbols are also included.
