Removing panels via spot welds, Question about re-use Options

[Gint]

I got one of these:

And I did some of this:

I know I went too deep on some of those holes. Getting used to using a new tool, you know how it goes. But, this is a 3/8, and I'll probably get a 1/4. These holes are awfully large. How do you got about filling that large void on relatively thin sheet metal when you re-use this part?

One more fun fact... the piece being "removed" would generally be the one getting the holes and the piece you would want to keep would be on the bottom.

Sometimes that's not possible (depending on the location of the weld path) and the rosette weld thing is the only way to go.

Let's say you had a large quarter panel cut off anotehr car. You would use your spot weld cutter/drill from the "backside" and pick the front portion off. The tool is designed to cut around the weld leaving the weld in tact. Then to prep the panel you would grind the remaining welds down and either spot weld as the factory did (not too many people use this option because the tub was put together in a certain sequence with numerous lenth spot arms) or MIG weld (most common).

Again, when using a MIG and you want to replicate/duplicate spot welds you would use a rosette pattern.
