Poor weld strength is one of the major problem experienced in the application of such weldments. It is mainly due to improper selection of process parameters. In order to achieve satisfactory weld strength optimization of welding process parameters is indeed essential. In this present context, the USW has been carried out to join dissimilar materials like A1100 aluminum alloy and CuZn37 brass plates of thickness 0.1 mm using Taguchi’s L16 orthogonal array design of experiments. The process parameters like amplitude, weld pressure and weld time have been taken into consideration. Taguchi’s S/N ratio concept has been employed to study the effect of different process parameters on the response like tensile strength; and finally, the optimum setting of process parameters has been decided in view of maximizing...

Pin-on-disc wear test of the composite was carried out and compared according to Taguchi design-ofexperiment. An orthogonal array exhibited and examined the influencing parameters like % of fly ash debris, typical load, sliding speed and track distance on the composite. Signal to noise ratio analysis optimizes the parametric condition that yields minimum wear rate, minimum frictional force and minimum coefficient of friction. A multi-criteria decision analysis method, TOPSIS is used to optimize the output, and confirmation test has been done to verify the projected model. ANOVA shows that applied normal load plays a vital role in increasing dry sliding wear of epoxy composites.

Pin-on-disc wear test of the composite was carried out and compared according to Taguchi design-ofexperiment.
An orthogonal array exhibited and examined the influencing parameters like % of fly ash
debris, typical load, sliding speed and track distance on the composite. Signal to noise ratio analysis optimizes
the parametric condition that yields minimum wear rate, minimum frictional force and minimum
coefficient of friction. A multi-criteria decision analysis method, TOPSIS is used to optimize the output,
and confirmation test has been done to verify the projected model. ANOVA shows that applied normal
