Where to start???
I agree with Ravi's query, the edge prep is not acceptable based upon the pic. Though the notches/gouges may not be over 3/16" deep it does not meet 5.15.4.3 Roughness Requirements meeting with sample 3 (C4.1 Sample Gauge).
Second, Round bar for Backing? What grade? Hot rolled, cold rolled, pin stock, do they even know? What does the WPS or job specs call for? I 'presume' the steel falls into one of the D1.1 classifications. But does it match the flat bar/plate grade?
Third, angle... I don't think so. It would need to be opened up wider than that. It may have been right before bringing it around to that orientation, but now it is too tight.
As to rather it is even a prequalified joint if those items were corrected... I'm having a hard time picturing it. I need to take a better look at 3.3 & 3.4 details and notes.
Have a Great Day, Brent
Just curious, Why are they using the round bar for backing vs using a piece of 3/8" bent plate? I'm not sure how I feel about the round bar in that joint due to the outside intersections between the plate and the round bar may act like a stress raiser more so than if an appropriate bent plate was used.
Are you the TPI reviewing the WPSs that are in place to determine if it is appropriate for the welding that is to take place?
I'm trying to figure out which Pre-qualified joint detail would allow such an arrangement....C-U2a?
