Writing of a Welding Procedure specification (WPS)

A typical working procedure specification is written with all the factors of production in mind. Both experience and latest technological awareness help to write an acceptable or successful WPS. The WPS is a list of the following welding variables with the proper values of these entered accordingly.

  1. Welding process
  2. Base metal
  3. Joint design
  4. Filler metal
  5. Position
  6. Preheat / inter pass / post heat
  7. Electrical characteristics
  8. Post weld heat treatment
  9. Gas(es)
  10. Techniques (stringer I weave bead transfer mode, orifice dia, etc.)
