Friction Welding of magnesium alloys

摘要

Magnesium alloys were welded by friction welding. The mechanical properties of the joint were investigated; the effects of welding parameters on flanging amount, wear amount and tensile shear load of the joints were discussed. The results show that the joint strength increases with the increase of friction force and decreases with the increase of upset force. As a result, we could obtain high quality weld joint when friction pressure is 2 kN, and upset pressure is 2 kN.
