Where should we send the flowers after the explosion?

Very droll I'm sure. I'll be using a proper industrial Oxford
oil-cooled arc welder circa 1973 for this job, not some crappy Chinese
"turbo" fan-cooled, low-duty-cycle job, so there won't be any
explosions.

Can't you just cut the whole shebang out and weld a new bit in like they
have done for generations before this dent pulling carry on

Which decade of late 19thC are you referring to?
Light dents, fair enough. Trouble is, some dents are bad enough to
draw in the surrounding metal and depending on where this happens, the
only remedy is to fully restore the correct geometry around the
affected area, which can only be achieved by pulling whilst tapping
down the resulting 'caldera' with a metal shrinking hammer.
