Welding Symbols on Drawings by E.N. Gregory and A.A. Armstrong

Welding Symbols on Drawings is an extensive handbook on welding symbols on drawings. E.N. Gregory and A.A. Armstrong have authored this weld symbol application book. There was a book published in 1982 with a name, Welding Symbols on Drawings. And it is an updated version of this book. Besides this, the book explains the use of welding symbols in British/European Standard BS EN 22553, International Standard ISO 2553 and American Standard ANSI/AWS A2.4-98.

All the symbols are revealed by keeping in mind the standards of ISO, BS-EN, and ANSI-AWS. The manual is very helpful in preparing any of the welding tests i.e. certified welding inspector exam. The following is all about the contents of the handbook.
