    TIG weld on Mild Steel_WPS parameters

    That's D1.1 right? By the look of your welding speed and wire size your WPS is for GTAW on all passes. The WPS your are trying to correct should at minimum record the processes. I would start at the beginning with a new WPS.

    Welding Procedure Specification

    I am a bit confused, in the summer edition of IT magazine the author said a common mistake is to list the positions as 1G,2G, 3G and 4G instead of F,V,H and OH. on WPS and PQR. Under Figure 4.3(see 4.3.4) Positions of Test Plates for groove welds it lists 1G Flat, 2G Horizontal, 3G Vertical and...

    welder qualifications when two methods are used

    I am bidding on a pipe job which requires our welders to use GTAW as a root and FCAW as a cover. How should I qualify our welders.
