4.1 General
A preliminary welding procedure specification/welding procedure specification (pWPS/WPS) shall provide all the necessary information required to make a weld. The information required in a pWPS/WPS is given in 4.2 to 4.4. For some applications, it can be necessary to supplement or reduce the list. Welding procedure specifications cover all certain range of the necessary information to make a weld. Some manufacturers prefer additionally to prepare work instructions for each specific job as part of detailed production planning.
Ranges and tolerances, according to the relevant standard (see 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
(see ISO 15607).
4.3 Information related to the parent material
4.3.1 Parent material type
— Designation of the material(s), and reference standard(s).
— Number(s) of the group(s) as given in ISO/TR 15608.
A WPS may cover more than one group of materials.
4.3.2 Material dimensions
— Thickness ranges of the materials.
— Outside diameter ranges for pipes.
4.4 Information common to all welding procedures
4.4.1 Welding process
The welding process(es) in accordance with ISO 4063.
4.4.2 Joint design
— A sketch of the joint design/configuration and dimensions or reference which provide such information.
— Weld run sequence given on the sketch, if essential for the properties of the weld.
4.4.3 Welding position
Applicable welding positions in accordance with ISO 6947.
4.4.4 Joint preparation
— Surface condition, cleaning, degreasing, including methods to be used.
— Jigging, fixtures and tack welding.
4.4.5 Welding technique
— Leftward or rightward welding.
— Blowpipe and/or wire/strip angle (if required).
