Experiments on magnetic pulse welding of T2 copper rotating band to 50#carbon steel tube were carried out. The metallurgical joint between them shows the wavy bonding mode,where the wavelength and amplitude are 60 μm and 30 μm,respectively. Almost no iron element diffuses into copper. The axial and loop shear strength of the welded joint are 91 MPa and132.37 MPa,which are much higher than the initial yield strength of copper. The torsion instability and bulging crack occur in copper and the corresponding ma...
