The first results showed poor behavior of mechanical properties; nevertheless, in modifying the process parameters, particularly rotation speed, advance speed and approximation speed, an adequate compromise of resulting mechanical properties were obtained. Tensile tests on joining dissimilar specimens ABS-PP, show as high as 90% of strength compared to the parent materials; in the best knowledge of the authors, no previous investigations have been reported for the joining of these two thermoplastic materials, using FSW joining technique. Furthermore, analysis of hardness near the welding zone and visualization with optical and scanning electronic microscope (SEM), were carried out in order to deduce the generalities of effect cause in the improvement of tension strength. 7th International Conference on Crack Paths Dissimilar joining of ABS and PP using friction stir welding (FSW) and mechanical properties evaluation M.A. Sánchez Miranda 1 , G.M.

Introduction The FSW technique to joint metals dates back to the last century, it was developed at the end of 1991 by the “The Welding Institute” in the United Kingdom [1]. The joining process implies a no-consumable rotating pin communicating energy by friction to the two facing surfaces, at the beginning metal alloys; nevertheless, in the last 1.
