Up Topic Welding Industry / Technical Discussions / 4 WPS to cover all thickness & diameter
- - By melayu Date 01-19-2006 02:48
I'm new to this forum.

I am developing welding procedure to cover all thickness and diameter for pipeline welding. I now there are 4 PQR that we can do to qualify all thicknes and diameter to be welded. But I forgot what is it.

Appreciate if any of the forum members can remind me what is it?

I believe you will find the breakdown of information if you refer to API 1104.

Depending on the, process used, base metal, joint design, position, filler metal, wall thickness and many other variables, you may need any number of PQRs. However, pipe diameter is not an essential variable.
