SAW procedures for what?
The source of your SAW procedures is your qualification.
Or, you can prequal, or purchase standardized WPS's. See AWS, and/or a manufacturers web site for 'suggested' parameters.
This may sound gruff but If you do not know what you are doing a WPS is NOT going to help.
You need to engineer and understand your welding process.
And you need skilled welding operators that can take that piece of paper and make it mean something.
If you have skilled WO's develope your own PQR.
