Experimental Investigation of Friction Welding on Similar Al Plate and Tube

The similar metal joint of ‘Al' plate to ‘Al' tube is essential in all most all industries now a days because of less weight, no inter metallic formation, environmental friendliness. For this work, friction welding process using an external tool was attempted to join ‘Al' plate to ‘Al' tube. Friction welding finds increasingly widespread industrial application as manufacturing method for joining parts in Fabrication, Automobile industries. Friction welding method as a mass production process is finding increasing industrial acceptance, for joining similar materials. For this present study, an experimental set up was designed and friction welding of ‘Al' plate to ‘Al' tube. Metals are taken in commercially pure form so as to understand the basic mechanism of joining. Firstly seeing the macrostructure for the samples having different hole diameters on the tube. Secondly finding the tensile strength. Later, finding the vicker's hardness test for the samples by comparing with tube, base metal and interface. Finally the results obtained were shown and discussed.
