Industrial Laser Cladding Systems: FPGA-Based Adaptive Control

Laser cladding is a deposition process, depicted in Figure 1, which uses a laser beam to melt the surface of a metallic substrate and a substance added in the form of powder flow so that the two materials are fused by metallurgical bonding. Usually, laser cladding consists of a processing head, where the laser beam and powder flow are generated, that moves over the target part. The melted powder particles and a thin layer of the substrate form a clad, whose thickness and penetration depend on the control parameters of the process.
