Sheet metal welds

If you see a seam between panels on the back, it's not fully welded. Knowing that your panels will need stretching, you want full penetration. MIG welds are harder than TIG and may crack if over worked. Please let us know if they do crack. Curious just how much they can take.
There's nothing stopping you from tacking the unwelded seams showing in your pics from the back side.
