WPS (ASME Section IX format) template

Welding procedure specification laid out by the QW-482 variable groups: joints, base metals, filler metals, positions, preheat, PWHT, gas, electrical and technique.

What you’ll need

  • WPS and supporting PQR numbers
  • Base metal P-numbers and thickness range
  • Filler classification, F-number and A-number
  • Electrical and technique parameters

How to fill in this WPS

Start with the WPS number, revision, welding process and supporting PQR numbers. Keep the supporting test record beside the draft: the WPS states the variables to use in production, while the PQR records the test that supports the procedure. Do not copy a range from another procedure without checking its supporting record and the applicable code edition.

  • Identify the joint design, root spacing and any backing.
  • Enter the base-metal specification, P-Numbers and applicable thickness and diameter ranges.
  • Record the filler classification, F-Number and A-Number where relevant.
  • Give the position, preheat, interpass and postweld heat-treatment details.
  • State the gas, electrical ranges and technique for each process used.

For example, if a job uses WPS-014 revision 2, enter its actual supporting PQR reference in the first group, then compare each material, filler and parameter range with that PQR before issuing the WPS. The example reference is fictional; it supplies no qualified ranges.

This page follows the groups in ASME's suggested QW-482 WPS format. The generator organises information you provide; it does not qualify a procedure or check it against Section IX. Have the responsible welding personnel review the source PQR, project requirements and final document before use.
