For our stainless steel time capsules, we grind the welds off
*manually*.  It is a long and arduous process (especially for new
stainless steel of the thickness we use, which is about 1/8").  We
had to do this for the City of Ontario (CA) capsule.  We were able
to salvage the bottom shell, but had to make a new top for it.  The
edges of the shell had to be filed down, too. While this is
expensive (time-wise), no heat is used other than that manually

As you grind the welds, some of the filings will inevitably fall
into the container.  For my capsules, this is not much of a problem,
since I use proper archival enclosures & boxes, but one needs to be
aware of the dusting, etc.

This may not help you much with the brass, and we are discussing
this now. I will let you know if we find anything that is more
