I did research the code but was left without an answer Also if this is a work issue I would be caucus of posting work issues with your name on them.
Welding EngineerI would start with reading the code, I am assuming you have access if you are working with code related welding. Thank you in advance for your contributions on the above questions, By the way, how can one be sure to have removed the root pass after having finished the back gauge?Ĭ) If I had qualified two separate PQRs, one welded solely with FCAW and the other welded solely with SMAW: Am I allowed to issue a WPS that mixes the two methods any way I want it (root, pass, fill and capping any way I want it)?ĭ) If the drawing specifies a single sided T-joint: Am I allowed to perform gauging and weld a pass from the back side without violating the code, or would this be considered as a weld repair from the back side. 1) root + 2) fill + 3) Capping, all welded from one side in a T-joint they intend to backgouge and remove the root run and fill it up from the back side using FCAW-gas shielded.Ī) Is the above really supported by the code? To me it seems to be a flagrant example of unauthorize welding since you have not qualified FCAW for the root run I don't care that your intention is to remove this root pass later on using back gauging. We are facing a situation out in production where the workshop has used FCAW all the way i.e. We have qualified a PQR on heavy plate (single sided CJP butt weld) where we used SMAW for the root run and filled it up using FCAW-gas shielded.
