Friction stir welding (FSW) of aluminium foam sandwich panels

Blog Article

The article focuses on the influence of Devils Claw welding speed and tool tilt angle upon the mechanical properties at the friction stir welding of aluminium foam sandwich panels.Double side welding was used for producing butt welds of aluminium sandwich panels applying insertion of extruded aluminium profile.Such insertion provided lower pressure of the tool upon the aluminium panels, providing also sufficient volume of the material required for the weldment formation.Ultimate tensile strength and flexural strength for three-point bending test have been determined for samples Headwear taken from the welded joints.Results have confirmed anticipated effects of independent variables.
