MIG (GMAW) 4F and some 2G
(Peterborough, Ontario, Canada)
roughly a 2 meter long, x 1 M wide, x 1 M high frame and structure made from 2" x 4" x 2" x 1/4" c channel and 1/4 plate (gusset and channel extensions). what you are seeing is the support structure upon which sat a vibrating screen for the feed prep portion of the portable density medium separator i used to build. the frame was welded in position and not ever rolled. We properly sequenced the welding to the minimize distortion. at this point i had only been operating for about year when i built it and i have more pics of the plant if any one is interested. very informative web site by the way!
