Has anybody come across this method of joining sheet metal prior to welding in inaccessible places where you can't easily clamp (hopefully pic is attached)?
Apart from seeing it on a mini restoration site I have also seen it used on the tv show Fantomworks.
I am not sure how the studs are inserted, maybe with a special tool.

They are called celco pins/clamps. There are lots of how-to and videos on the net

You can also use self tapping screws to hold panels together, seems dodgy but gives you the same finish and is way cheaper.
