It's always hard to explain just exactly what I do for my 40 hours a week in just words, so here are a few pics of one of my projects I'm working on right now. It's a 48"x24" stainless sink for Grant hospital fabricated from 4 pieces of 16 ga. 304 stainless #4 finish. It started as a 48"x96" and a 48"x120" sheet that was sheared into the 4 pieces, notched with a portaband, and formed on our 60 ton press brake. Then the pieces were tacked together, welded, and at this point only a little bit of the finishing has been done. It's a pretty lengthy process, at the time of the last picture I have just over 30 hours into it. Some of that time was used making a punch and die from scratch to recess the drain in the bottom.
At this stage the first three pieces are welded together, first on the outside, then again on the inside, total of 160"s of weld.

Here is a closer shot of the inside weld, it's just a tad smaller than 1/16" wide.

Here the forth piece, "the skirt" has been added and welded. Another 120"s of weld

Here is just the start of the finishing. As you can see, when done it will be very difficult to see where there is a brake (bend) in the metal or a weld.
