Joining phenomena and tensile strength of friction welded joint between pure aluminum and pure copper

This paper describes the joining phenomena and the tensile strength of friction welded joint between type 1070 pure aluminum (CP-Al) and oxygen free copper (OFC). When the joint was made at a friction pressure of 30 MPa with a friction speed of 27.5 s-1, the upsetting (deformation) occurred at the C...

When the joint was made at a friction pressure of 30 MPa with a friction speed of 27.5 s-1, the upsetting (deformation) occurred at the CP-Al side. When the joint was made at a friction time of 2.0 s, the whole weld interface on the OFC side had the transferred CP-Al, and it was obtained approximately 30% joint efficiency. Then, the joint efficiency increased with increasing friction time, and it was obtained approximately 63% joint efficiency at a friction time of 12.0 s. The joint fractured at the weld interface, which had a CP-Al adhering to the weld interface on the OFC side. When the joint was made with friction times of 2.0 s and 6.0 s, the joint efficiency increased with increasing forge pressure and then the joint was obtained the CP-Al side fracture at a forge pressure of 135 MPa or higher. However, the joint did not achieve 100% joint efficiency because the adjacent region of the weld interface at the CP-Al side was softened. In addition, the joint at a friction time of 2.0 s had no intermetallic compound (IMC) layer at the weld interface although the not-joined region was slightly observed. On the other hand, the joint at a friction time of 6.0 s did not have the not-joined region at the weld interface although the IMC layer was slightly observed. In conclusion, to obtain higher joint efficiency with fracture on the CP-Al side, the joint should be made with higher forge pressure, and with the suitable friction time at which the entire weld interface of the OFC side had the transferred CP-Al.Masaaki KIMURAYuusuke INUIMasahiro KUSAKAKoichi KAIZUAkiyoshi FUJIThe Japan Society of Mechanical Engineersarticlefriction weldingpure aluminumpure copperjoining phenomenatensile strengthfriction welding conditionnot-joined regionintermetallic compoundMechanical engineering and machineryTJ1-1570ENMechanical Engineering Journal, Vol 2, Iss 1, Pp 14-00328-14-00328 (2014)
