cast iron repair and something different with CorTen

admin

First job doing cast iron repair using the Nickel 99 repair electrode.  Didn't know which polarity to use at first, but seemed like DCEN gave much better results.  I didn't feel like fussing with preheat, as this was a woodstove door with the glass still in place, and no easy way to remove it.  So I just welded a pass (1") and found something else to do while it cooled.  It was a bunch of passes, maybe 20 or so, but I don't mind getting paid to learn new stuff.    The other one is a sculpture I made out of some leftover 3/8" CorTen (A588) and some old damp 7018.  The shape is called a rhombic dodecahedron.  I made a regular dodecahedron a while back, only about 6" tall, but I didn't want to try and fit up pentagonal pieces on something this large, so I decided on the rhombic version.  Lots of grinding, but only had two spots of porosity in all 30+ feet of weld.  It stands about three feet tall, and I am working on a swivel base for it, so you can spin it.
