I have a pair of rimless glasses that are made out of titanium, and
the piece that hinges one of the arms of the glasses to the lens
split in half. Can it be soldered/brazed or welded (tac or arc
Possibly, but unlikely. I’ve had some success with laser welding
eyeglass frames, but I’ve also had several “comebacks.” The problem
is that titanium eyeglass frames are not monitored for titanium
content the way precious metals are. Your “titanium” frames may
contain as little as 1% titanium.
What works best in laser welding these frames is to weld a small
amount of white gold to each piece to be joined, then weld the gold
together. I’m not sure if it’s possible to do that with a torch. I
don’t know if arc, tack, mig, tig or any other options will work for
you, but you might be able to find a competent laser welder in your
