Weld Rainbow Makes For Neat Logo

I haven't done any metal work for quite some time. One of the big reasons is that I've been waiting to get some of my welding gear back from a friend who lost it in his overcrowded basement. (Yes, I'd still like it back, thanks)

I finally gave up and bought a new pair of oxy welding goggles. I took a close up of the metal's discoloration after I made a really large weld.

The bar was salvaged from the Freemont transfer station, languished in my garage for a few years, then had it's nasty rust knocked off with a grinder about a week ago. I then welded a bunch of stuff to it (The weld was about 2 inches from the discoloration). I absolutely love weld discoloration. It's like God's extra rainbows of love for people forced to breathe metal fumes all day.
