Sounds like one of those middle eastern jokes to see how guliable we Americans really are, nothing in any of the AWS Welding Handbooks or the Jefferson Welding Encyclopedia, Let me see a PQR and WPS.

All of the PQR 's and WPS's were done in   this country   in 1968.

Professor John Zotos of Northeastern University in Boston   did some of the early work in conjunction

I got to work there on one of my co - op jobs.

John Zotos   is afellow of the AWS
