OPTIMIZATION OF GAS METAL ARC WELDING DURING WELDING OF MPM SANDWICH SHEET METAL

Abstract

With increase of demands for lowering noise and vibration levels, there are many new materials developed that can satisfy these demands. One of these materials is metal – polimer – metal (MPM) sandwich panel used as anti-aqoustic element in industrial genera-tors and electric motor housings. Problems related to welding refer to the polymer interlayer, that is, buckling and separating of steel plates. In this paper, welding technology optimization is shown, so that the joining process is as economical and with as low evaporation of polymer interlayer as possible.
