Designing experiments to study welding processes: using the Taguchi method

Abstract

Identification of significant process parameters using experiments needs to be carefully formulated as it can be a resourcedemanding process. Using appropriate statistical techniques such as the Taguchi method of factorial design of experiments,the number of necessary experiments can be reduced and the statistical significance of parameters can be safely identified.In the case of linear friction welding it was found that the frequency of oscillation, power input and forging pressure arestatistically insignificant for the range of friction pressures studied.
