Experimental Validation of a Laser Heat Source Model for Laser Melting and Laser Cladding Processes
Selective laser melting (SLM) and laser cladding are laser additive manufacturing methods that have been developed for application to the near-net-shape process and 3D printing. The temperature distributions and track profiles of SLM and clad layers require additional in-depth investigation to optimize manufacturing processes. This research involved developing a tailored laser heat source model...
متن کاملModeling of Heat Transfer and Fluid Flow in the Laser Multilayered Cladding Process
The current work examines the heat-and-mass transfer process in the laser multilayered cladding of H13 tool steel powder by numerical modeling and experimental validation. A multiphase transient model is developed to investigate the evolution of the temperature field and flow velocity of the liquid phase in the molten pool. The solid region of the substrate and solidified clad, the liquid regio...
متن کاملSeedling emergence response to temperature in safflower: measurements and modeling
Quantitative information about the response of seedling emergence totemperature for safflower (Carthamus tinctorius L.) is rare. The main objective ofthe present study was to develop a model for predicting days to emergence forsafflower as influenced by the temperature. In this regard, a field experiment with arange of sowing dates and four safflower cultivars were conducted to describe theresp...
