BS 499-1:2009 Welding terms and symbols. Glossary for welding, brazing and thermal cutting

BS 499-1:2009 provides terms, symbols and definitions for welding, brazing and thermal cutting of metals. Some definitions might also apply to non-metals.

This standard is intended for designers, those drafting welding specifications, welding production, manufacturers and inspection personnel.

This is a full revision of the standard, and introduces the following principal changes:

  • Charts showing the derivation of welding, cutting and allied processes are given
  • Commonly used friction stir welding terms are included.

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.

BS 499-1 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 to not 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BS 499-1:2009 supersedes BS 499-1:1991, which is withdrawn.
