Little known fact: I cut my welding wires in half before I use them. When they're new and long like that, it distracts the heck out of me.

My first attempt to shoot street in a long while now. I wasn't as thrilled as I thought I would be. I think I'll stick to still life and other non-living things.
This man has been working with this metal rack throughout the summer. I think its for the stuff he sells in his store in the tunnel at Slussen.
Lucinda Lee Katz and Don Alexander learn to Arc Weld and cut steel with the Oxy-Acetylene torch. Assisted by Richard Carrico they design and weld a 9' tall tree sculpture out of recycled rebar from the step #1 and #2 construction. The tree will be planted on Ring Mountain and have wind chimes hung on it by MCDS students after the planting.
In less than 30 seconds, molten steel runs into the join and the overflow goes into the pans. When cool, they remove the jig and grind down the seam.
Crude, but effective. Lots of welding practice here.
3/4" x 065 A36 hot rolled seamed square tubing (doesn't weld too cleanly) for the frame.
0.125" 1018 cold rolled strip (welds better) for the caster mounting pads.
Welding a grating that must stand up to vehicle traffic on a beachfront property. Four welds per joint.

Mild steel (A366/1008) is cheap to buy ($3.50 or so per. sq. ft.) but getting it sheared to the sizes I wanted (1.5" x 4" coupons) kicked the price up to almost $50.....
Luckily, Hahn Rossman down at Alki foundry was willing to help me out. As a bonus, I got to visit his shop which is always entertaining since he always has a lot of interesting projects on the go.
48 pieces here, or 24 practice T joints. Should help me make some progress.
I didn't do this weld. Someone else did. It sure screwed up the experiment, though; there's supposed to be a high vacuum (< 1e-5 torr) inside that tube!
The part is supposed to be a cryogenic adsorption pump for an instrument (www.qdusa.com)

Benefits:
-Oscilating laser focus results in wide weld bead in a single path.
-High quality weld from the side or through the top plate eliminates flipping of large plates.
-Self-fixturing tab&slot design eliminates tooling.
-Process enables complex geometries.
