Re: [MW:24535] 24528] WPS for SAW

Dear Laxman,

For IS pipes you can follow IS 7307 for WPS/PQR.

But You can not do welding of 20 mm and above with square butt, double V groove can give you satisfactory results.Tandem arrangements will be needed for the same.

Rest all parameters and essential variable you can find in IS 7307.

You can get format of WPS/PQR in IS 7307 OR ASME Section IX

Anosh Wankhade.

Pipe > 20mm manufactured with SAW longitudinal seam has a precisely machined weld preparation. It is not done with a square butt. Are you aiming for a low quality product or one for pressure piping or pipeline service.
