The thesis presented is dedicated to the forming of the weld cladded work pieces. The proposed idea is based on reversing the classical fabrication layout of simple cladded preforms by performing the hot forging process after the weld cladding. The expected benefits are structural refinement of fusion weld solidification by hot forging structure and the ease of automation of MIG cladding on simple preforms. Initially a methodology is setup for the MIG cladding process on simple shapes which is based on two approaches: the statistical experimental study of a single bead cladding and the determination of the optimum bead overlapping by using two overlapping models to setup the link between dilution rate, nominal energy of welding and metallur...
