Speech Title:Solid Bonding Testing Methods and Welding Seam Strength for Hollow Extrusion of Aluminum Alloy 7075
Abstract: In recent years, the demand for high performance and light materials is increasing. Aluminum alloy is commonly applied to aerospace, precision and defense industries, given its high specific strength, light weight and good corrosion resistance. Aluminum Alloy 7075 has many good mechanical properties; however, its bonding strength is poor and is difficult to produce extruded hollow products. Although some researchers proposed several methods to study welding strength of Aluminum alloy, related study for high strength Aluminum alloy in hollow extrusion process is not enough. In this speech, several testing methods will be discussed, and then an easy and new testing method by using compression testing to mimic the bonding interfaces occur in hollow extrusion will be proposed. The guiding chamber effect on contact pressure of split materials during hollow extrusion processes are studied by finite element analysis. Further, finite element analysis to simulate two different types of hollow extruding die configurations for square tube extrusion process as well as non-symmetric cross-section hollow extrusion are studied to obtain the optimal extrusion parameters such as ram speed, billet temperature and die configurations. Experimental studies corresponding to the above hollow extrusion processes are conducted and compared.
