Laser cladding is an additive manufacturing process that a laser generates a melt-pool on the substrate material while a second material, as a powder or a wire form, is injected into that melt-pool. Among all laser processes, laser cladding offers the most extensive variety of possibilities to alter a component at its surface. Despite immense potentials and advancements, the process model of microstructure evolution of laser cladding process has not been fully deve...$28.00

The behavior of assist gas flow in the groove of different material thickness was investigated. Based upon the real shapes of cutting grooves, simulation model was established using the CAD drawings. The cross section in the direction perpendicular to the cut have a throat at both side walls in the groove owing to the effect of focal position. The simulation results shows that these throats can make accepted the assumption of the equation of continuity of gas flow under the boundary ...$28.00
