I produce a lot of products which are boxed and welded sheet metal. This usually leaves the majority of the corners welded which I cannot bend in a brake. As I go into production, I need a more efficient method of removing all of the excess meld material other than hand held grinders and flap wheels.
I saw an episode of "How Its Made" featuring the production of metal caskets. They have a similar issue and solution using a large belt sander, which appears to be a custom machine:

I have also seen larger belt sanders which seem to be for woodworking but would seem useful if they offered abrasive belts for steel.

Any help would be most appreciated!
