Abstract:
A method of using a computer processor to perform simulation of the laser beam material deposition in which said computer processor executes computations according to an algorithm comprising the steps of:a) entering numerical data representing geometry of the part to be fabricated or repaired; b) entering the thermo-physical properties of the deposited material or materials; c) entering the thermo-physical properties of the alloy of the said materials; d) entering the distribution of the sizes of the powders of the said deposited materials or diameters of wires of the said deposited materials; e) computing the temperature of the said powers particles; f) computing the particle size decrease due to evaporation; h) computing the extinction of laser beam in the powder jet; and i) computing the thermal field and the shape of the molten pool for different locations of the beam on the surface of said deposited material.
