Aspects of the Influence of the Taper Profile of the Welding Tool pin on the Dimensions of FSW and SFSW Welded Joints in EN AW 1200 Aluminum Alloy

Abstract:

The joining of metallic materials by using the friction stir welding process is carried out with rotating welding tools having different geometries. The paper presents aspects that show the influence of the conical profile of the welding tool pin on the dimensions of friction stir welded joints FSW in air and SFSW in liquid environment for EN AW 1200 aluminum alloy. The tools analyzed in the experimental research have had smooth conical pin and conical pin with four flat chamfers respectively, macrostructural investigations being carried out to a comparatively analyze of the welded joint dimensions. The results are useful for experimental research on FSP processing in air and SFSP in liquid environment of aluminum alloys that will be carried out within the Nucleu PN 23 37 01 02 project underway at ISIM Timisoara.
