Butt Joint Question

[JoshStratton]

You know, the only way I know that I am making progress on my project is that questions keep popping into my head the further I go.

I have welded 2 sheets of steel together using a butt joint. I have a large 4 or 5 inch overlap that, while presenting a nice support, is also in the way. Do you normally flip the piece over and weld up the hanging side of the joint, or cut some of it off?



I am going to need to cut a 4 inch hole right in the middle of it and am not quite sure how to handle it.





Oh yeah! I am getting some Blow-through from time-to-time. Can I reduce this by slowing the wire speed just a bit?
