The present work aims at investigating the feasibility of Friction Stir Welding (FSW) process in joining blanks in thermoplastic polymer material, additively manufactured by performing 3D printing processes. To this purpose, ABSplusTM-P430 blanks were realized by means of the fused deposition modeling process and subjected to FSW operations. Different tool sinking values, rotational and welding speeds were investigated. Then, the effect of welding parameters on the mechanical performances of joints were studied by means of flexural tests at room temperature. Finally, an optical microscope investigation was carried out to observe the fracture surfaces of deformed specimens and to investigate the welding mechanisms.

Abstract

The present work aims at investigating the feasibility of Friction Stir Welding (FSW) process in joining blanks in thermoplastic polymer material, additively manufactured by performing 3D printing processes. To this purpose, ABSplusTM-P430 blanks were realized by means of the fused deposition modeling process and subjected to FSW operations. Different tool sinking values, rotational and welding speeds were investigated. Then, the effect of welding parameters on the mechanical performances of joints were studied by means of flexural tests at room temperature. Finally, an optical microscope investigation was carried out to observe the fracture surfaces of deformed specimens and to investigate the welding mechanisms.
