BS 499-1:2009 - welding terms and symbols (glossary)

A full revision of the standard, this publication introduces charts showing the derivation of welding, cutting and allied processes that are given. This standard has been aligned, as far is as practicable, with existing European and international lists of terms and definitions for welding including BS EN 1792, PD CEN/TR 14599, BS ISO 857 (all parts) and BS EN 13622. Commonly used friction stir welding terms are included.

BS499-1 defines terms relating to more than one section, welding with pressure, fusion welding (welding without pressure), testing, weld imperfections, cutting, health and safety.

Where it was felt that an existing definition needed clarification, this has been done while striving not to contradict the existing definition. As far as practicable, the numbering system used in this standard follows that of BS EN 1792, with new numbers allocated to terms that are not in the European standard.

BS 499-1:2009 supersedes BS 499-1:1991, which is withdrawn.

BS 499-1:2009 (ISBN 978 0 580 58471 8) is available from BSI at 216 (plus packaging and postage) or 108 for members of BSI.
