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.

Welding process
Base metal
Joint design
Filler metal
Position
Preheat / inter pass / post heat
Electrical characteristics
Post weld heat treatment
Gas(es)
Techniques (stringer I weave bead transfer mode, orifice dia, etc.)
