Abstract

In Friction stir welding, microstructure degradation and mechanical strength loss in the weldment and heat affected zone normally occur when the weld cools from 500 ℃ to 100 ℃. As can be understood, the variation in the rate of cooling the weldment controls the variation in tensile strength, impact strength and other mechanical and metallurgucal properties. The proposed model is derived through friction stir welding tests conducted to approximate the time taken for wedment to cool from 500 ℃ to 100 ℃. Also, the proposed model takes material characteristics, process parameters, and environments into account in “friction stir welding”. A combination of parameters, which are without dimensions, was generated, and the coefficient of this combination was determined by using the experimental data-driven MATLAB software for the non-linear analysis. The proposed model was checked using experimental work and the results of other researchers on the cooling time. The reason behind the discovery of the model was predicting the time of cooling of AA 6063 T6 plate welding by the use of friction stir welding with 97% accuracy.
