Anyone else have to fix a CPP bolt in notch?

[8mpg]

Just got the notch in today and while it looks like great penetration and teh outside welds look great, Im less than impressed. Im going to have to go back and weld the inside seams. There was a lack of penetration though the heat rings make it look like it was a good weld. Here are some pics:

Looks good from far:


Closer up, all you see is a gap between the pieces of steel:

Here is the typical penetration for the whole thing...1/8" or so. The thing in my mind is about 1/2 welded and 1/2 as strong as it could be.


Anyone else have a problem with theirs? I sure wouldnt feel safe just bolting it on out of the box. To give them some credit...I just looked over it some more and some of the welds are nice and penetrate better than others, but definitely not 100% on the 1/4" steel. Im gonna say at most its 75% penetration on 30-40% of the welds.
