billet edge delamination

I am attempting to make a spider web design in my billet. When I pinched the billet in the center my outside edges delaminated some. The delamination mostly occured where I had inserted two thin pieces of 15n20 between the bars. The billet seemed to be welded well before I started pinching.

What can I do to avoid this and can I save the billet with the delamination? The delamination doesn't seem to have gone to far into the billet, just the outside edges.

Hey Mark,
What your refering to is a pretty common thing to happen with those types of manipulations. They can be a real pain sometimes and other times no problem. All I can say is flux thoroughly before the next weld and weld the billet from one end to the other being careful to overlap your welds as you go.
