That is the only real complaint I have about electrical welds in
decorative ironwork. Short of CNC TIG, the beads are just so unsightly
and add greatly to the CF (Cheese Factor) of a piece. Sometimes this
doesn't matter, but sometimes it REALLY matters. All my MIG'd joints
got the file or angle grinder treatment on anything that wasn't either
completely hidden or on "cheap" work. The only TIG joints I've seen
that I like as-welded are on the titanium bike frames by Merlin. Those
beads are works of art in themselves. If you ever run into a Merlin,
take a moment to observe the work and you will know what I mean. They
are truly beautiful.
