Given sufficient volumes and proper technology setup, in-die welding can save big over stamping then welding as a secondary process. Here's the proof. The best path from point A to point B is a straight line. Obviously, that's the shortest distance and most direct route - with no detours along the way. An ideal lean stamping operation will have similar attributes. The ultimate-material into the press, finished parts and components exiting the press. Given sufficient volumes and efficient technology, many secondary operations - those pesky detours that eat up time, productivity and profit - can be incorporated into press work via in-die operations. In-die welding is an excellent example. The payoff to eliminating welding as a secondary operation: higher productivity, higher quality and simplified scheduling.
