Laser Aided Manufacturing Process (LAMP) can be applied to repair steel die/molds which
are currently repaired using traditional welding process in industry. In order to fully
understand the advantages of laser deposition repair process over traditional welded-repair
process, the mechanical properties such as tensile strength and hardness of H13 tool steel
samples produced by these two processes were investigated. The microstructure and fracture
surface of the samples were analyzed using optical microscope and SEM (Scanning Electron
Microscope). Moreover, depositions on substrates with different shapes were studied to
evaluate the performance of LAMP on damaged parts with complicated geometric shape.Mechanical Engineerin
