The reliability of experimental data obtained in friction welded titanium alloy and stainless steel with copper interlayer by using various interlayer thicknesses and upset time are investigated using the maximum likelihood method for the estimation of the Weibull parameters of the results. The results indicate that among the various process parameters, interlayer thickness was significant. Further the reliability of the tensile strength was estimated using weibull distribution. Using this technique in conjunction with the experimental data, we can predict the output, in this case tensile strength more accurately and minimize their impact. Titanium alloy when directly bonded to stainless steel, improper bonding happens. Hence an interlayer in the form of copper is added to have successful joints.
