Studying the construction of some commercial custom NSF sinks & trying to figure out how to fab something similar in construction & appearance. These appear to be TIG welded from separate press-brake-bent sections - as opposed to the common deep-drawn single sheet stampings of "home" sinks.
On the visible surfaces, the weld beads are ground flush and then the material is brushed to a uniform finish where the joints are invisible. The outside or non-visible surfaces show conventional weld beads.
What I don't get is how they keep the sheets so flat. Why haven't all the weld lines shrunk and turned it into a wavy pretzel? How do you weld something like this, continuous beads, watertight, and keep it looking so good?
I'm no master of distortion control, but this is way beyond what I think I know about distortion control in typical structural projects. What techniques are used in a production shop? Fast automatic welding? Heat sinks? Annealing and/or flattening after welding?
thx
