Abstract
This paper discusses the effect of weld parameters on peak temperature during the friction stir welding process. The weld parameters such as rotational speed and welding speed are considered for this analysis. Friction stir welding trails were conducted on 6 mm AA6061-T6 plates for different combination of process parameters using Taguchi orthogonal array. Thermocouples were inserted into the plates at different distances from weld center line and temperatures were measured during friction stir welding at regular intervals. Using the Taguchi method, Peak temperature is calculated for untried combinations of process parameters. Graphs depicting the effect of different weld parameters on the peak temperature were presented and analyzed.
