Title: Method for joining aluminum
Inventor: SATO SHOICHI
IPC: B23K1/19
Filed: 1992-06-10
Abstract: PURPOSE:To satisfactorily join aluminum materials with each other in a short time and to reduce cost. CONSTITUTION:Al-Si brazing filler metal 1 containing flux is interposed between the joining surfaces of two aluminum materials A1, A2. Both aluminum materials A1, A2 are pressurized in the direction pushing the joining surfaces at 0.01-20kg/mm<2> pressurizing force. Ultrasonic vibration is imparted to at least one side of the aluminum material A1 to break oxide films on the joining surfaces of both aluminum materials A1, A2 and the surface of the brazing filler metal 1. Further, by imparted ultrasonic vibration, friction heat is generated among both aluminums A1, A2 and the brazing filler metal 1. At the same time of this, by conducting the current between both aluminum materials A1, A2, resistant heat is generated. By melting the brazing filler metal 1 with the friction heat and the resistant heat, both aluminum materials A1, A2 are brazed.
