3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in prEN ISO 15607 apply.
4 Technical contents of Welding Procedure Specification (WPS)
4.1 General
The Welding Procedure Specification (WPS) shall give details of how a welding operation is to be successfully performed.
Welding Procedure Specifications may cover a certain range of thickness of the joined parts and may also cover a range of parent materials or welding consumables. Some manufacturers may prefer additionally to prepare work instructions for each specific job as part of detailed production planning.
Information listed in 4.2 to 4.4 is adequate for most gas welding procedures. For some applications it may be necessary to supplement or reduce the list.
Ranges and tolerances, according to the relevant standard of the series (see prEN ISO 15607) and to the manufacturer’s experience, shall be specified where appropriate.
An example of the WPS-format is shown in annex A.
4.2 Information related to the manufacturer
Identification of the manufacturer;
Identification of the WPS;
Reference to the Welding Procedure Qualification Record (WPQR) or other documents as required.
4.3 Information related to the parent material
4.3.1 Parent material type
Designation of the material, and reference standard;
Number of the group as given in CR ISO 15608.
A WPS may cover more than one group of materials.
4.3.2 Material dimensions
Thickness ranges of the joint ;
Outside diameter ranges for pipes.
