You didn't mention if this is being compared to prequalified joint details. If it's being compared to a prequalified partial pen BP1 joint (not beveled), I would consider it to be different. If it's being compared to a full pen BL1 joint (not beveled), there's a prequalified note that states "the orientation of the two members in the joints may vary from 135° to 180°", which allows the joint to be angled as you've described, but then it creates a problem with your 20° bevel, which is outside of prequalified +/- degree parameters, and, this prequalified 135° to 180° note doesn't apply to a partial pen joint with no bevels. Also, you didn't mention the base material thickness, so the prequalified minimum and maximum base material thicknesses need to be compared to the actual material thickness.
Here's a little more info. The PQ was run to Clause 4. The plates themselves were not beveled, and were welded at an angle so that the butt joint actually had a 20 degree included angle. I know that isn't technically correct, but that is the best way I can describe it. The weld test saw only 65% penetration, so it is not CJP. The plate thickness was 3/16.
So, does this qualify for a flat, single-V groove weld with a 20 degree included angle? Or are you limited to this joint orientation? That is what I'm really trying to figure out. Again, if I could post a picture it would help explain what I'm talking about...
Welcome to the Forum Matrix !
Curious about a couple things.
1. base metal thickness ?
2. Is the assembly restrained at the 20 degree preset, or does it come flat as the weld is completed?
3. SAW electrode size?
4. Current range qualified (amps)?
5. Polarity DC+, DC-, or AC ?
