MIG welding with preheat

Last night I finished up the mounts for the leveling feet of the utility benches I’m making. Of every thing that needed to be done, the mounts where the one thing I was concerned about.  Somehow I needed to figure out how to weld the two pieces together, without imparting a lot of distortion in the final part. After reading a bunch of posts on Welding Web, and asking a few question I determined that the best way to do this was by pre-heating the two pieces before welding them together. I used a cheap propane torch to preheat them to over 500°F. I’ll let the pictures do the talking, but I think it worked because the beads are nice and fluid looking.
