Occasionally I have this problem and thought I would ask for some
expert advice. I fabricate quite a few Sterling silver half-round
bands on a regular basis… Sometimes I find that I get pitting
along the solder seem during the finishing/polishing process. I may
make 50 rings that turn out fine and then have 5 in a row that I get
pitting (always in the seam) and can’t figure out why. Has anyone
had this problem? I prepare the joining ends so that the connection
is sound and there are no voids. The metal is clean when I
solder…and I use plenty of flux… Are there any suggestions as to
what I’m doing wrong?
It can drive one crazy when they’re at the polishing stage only to
find that they have to saw through, resolder, and refinish!
Thanks so much for any input…
