Friction stir welding aluminum alloy Amg2m thickness of 1.5 mm

Abstract

Among the huge number of different welding technologies, it is worth noting friction welding with mixing. This process does not involve the use of protective gases and consumable welding materials. At the same time, it is possible to obtain a high-quality connection without the use of high temperature. The technology is used in most cases in the processing of aluminum and some other alloys and is increasingly being used as an alternative method of joining, used instead of other types of welding – electric arc, laser, as well as bolt and rivet connections due to reduced energy consumption and the total weight of the resulting structures. At the same time, the quality of the resulting seam directly depends on the processing parameters and the material of the tool used. In this paper, in the course of experimental studies of the technology of friction welding with mixing of plates of aluminum alloy AMg2M known for its high corrosion resistance, ductility and good weldability with a thickness of 1.5 mm, a tool for friction stir welding was developed, welding modes were determined and the study of welded joints was conducted.
