Abstract

In this study, the laser edge-welding process is investigated as a mechanism for joining laminates and eliminating steps on the surfaces of tools fabricated by layered manufacturing techniques. An Nd:YAG laser (Lumonics JK706) was used to shape the edges and join the laminates together. The experiments were carried out on 1 mm thick mild steel. The effect of peak powers, peak power densities, welding speeds and beam-edge overlap percentages and the angle of the laser beam incidences were investigated. The work also shows the use of the optimum parameters in the production of hemispherical tool primitives. It also presents results of tests to ascertain the resistance of these tools to typical working environments.
