AWS specifies minimum fillet sizes based on the thickness of the parts being joined. My question is what to do if a part has already been welded with a size below the code minimum.
I am OK with the smaller weld size based on strength required at that joint, but not sure what to do about code compliance. Options as I see them:
1. Build up the weld to the minimum size. However, it seems like that would not address the underlying reason for the minimum sizes, which is based on getting a quality weld with good ductility and fusion. You could just be covering up a poor weld.
2. Gouge out and reweld at the correct size. Certainly would fix it, but more work than I want to do
3. Leave as is. I have mag particle testing showing the welds are good, and I am good with the strength of the as-welded size. Only concern here might be that MT would not necessarily reveal sub-surface fusion issues.
I am leaning toward #3. I think I would feel comfortable defending that.
Anyone out there have any thoughts to share?
