Abstract

Joining Advanced Pore Morphology (APM) sandwich panels with Friction Stir Welding (FSW) has been investigated in this work. APM foam based sandwich panels are compound of APM foam bonded to two 1 mm thick sheets of EN AW 6082-T6 aluminium alloy. Several different concepts of butt joint were investigated with and without additional material between panels. A classic tool for FSW was used with tilt angle of 1.5°. Tool rotation speed was constantly 1900 min-1. Welding speed varied from 95 to 235 mm/min. Through several iterations, the parameters were changed together with joint design. From the visually acceptable joints specimens for macrographs and mechanical testing were prepared. Charpy impact test and tensile strength test were conducted. A joint design with welding parameters was determined at which acceptable welds can be obtained. Suggestion for the further research is to increase the number of samples considering investigation of higher welding speed. The unique properties of APM sandwich panels make them an attractive alternative as a cost effective and easily applicable material that can be joined with FSW.
