Research and analysis of friction stir welding parameters on aluminium alloys (6082-T6)

Abstract

Research field related to geometrical and mechanical parameters in friction stir welding process is current and insufficiently explored, it is particularly present considering the class of aluminum alloy series 6000 (AlMgSi). The research paper is related to the friction stir welding of aluminum alloy 6082-T6 (AlMgSi1Mn) with the thickness of 7.8 mm. The research paper includes forces measurement: the down force - Fz, which is known as the welding force, traversing force Fx - and side force - Fy, as well as mechanical testing - tensile testing of welded joints and tensile testing of welding zone using standard machines and standard test pieces. The paper includes the drawings of the designed supporting equipment which allows measurement of forces by the friction stir welding process, the analysis and discussion of the process are included, as well as results. The experiment was performed in the laboratory of the Mechanical Engineering Faculty in Podgorica.
