Abstract
The experimental investigation has been conducted to determine the emissivity, absorptivity and temperature distribution for a stationary and a moving Gaussian laser heat source on Ti6Al4V alloy plate workpiece. Also a three 3D transient finite element model has been developed to predict the temperature distribution in Ti6Al4V alloy plate workpiece. It is found that the temperature profile is strongly dependent on the parameters of the laser beam and material properties. Parametric study shows that the temperature on the incident surface increases with increasing laser power and decreases with increasing laser scan speed and laser spot size.
