Welding Symbols on Drawings (Free PDF)

File Size: 740 Kb

This book is an updated version of Weld symbols on drawings published in 1982. It describes the application of weld symbols in British/European Standard BS EN 22553, International Standard ISO 2553 and American Standard ANSI/AWS A2.4-98.

References to ISO 2553: 1993 and ANSI/AWS A2.4-98 have been shortened, for convenience, to ISO and AWS where the full reference is not of primary concern and the context makes the abbreviated reference clear. The BS EN 22553 Standard is identical to ISO 2553 so any reference to the ISO standard applies equally to the British standard.

Only the representation of a given weld on a drawing is covered in this book. This does not include the design of the welded joint. The drawings are not necessarily to scale and the weld shapes shown are for the purpose of illustration only and do not represent recommended practice.
