Whilst doing some MIG welding, a bit of spatter landed on my wedding ring:

It is quite well bonded, but whether it's "welded" could be argued. I'd
say it's a matter of whether the steel was molten at the time of
contact. If so, it's welded, if not it's gold brazed. G - how much
gold brazing have you done?
