I am hoping someone can help me understand an incident that occured
yesterday, from a metallurgic point of view.
Having recently remodeled, we are moving into our new “shop,” (ie,
the garage), and I am finding all sorts of pieces and parts to make
things out of. I had this old 24 ga rectangle of marriage of metal -
copper and sterling with a wave down the length, so I decided this
could be cut in two and made into hoop earrings.
I curled up the metal into the hoop shape, then decided it needed sq
wire along the edges to finish it off. So I soldered 18 ga SS wire to
each side edge (long edge of the rectangle), then the first short
edge. As I was soldering to the second short edge, (with easy solder
now) the thing EXPLODED right along the marriage seam. The joints
did not fail, per se, it literally burst apart! Fortunately it did
not hit me (but it did singe my bench top!). It exploded only seconds
after I put the torch on it.
Can anyone help me understand what happened here?
thanks a lot.
