Abstract:

Friction welding of Al 7075-T6 alloy and 316 L stainless steel carried out for different times under a constant friction and forging pressure, a forging time, rotational speeds. Microstructures of the welds were examined by scanning electron microscopy and optical microscopy. The results showed that all of the welded samples were free of any or crack along the weld interface. The chemical compositions of the interface of the welded joints were determined by using energy dispersive spectroscopy. The micro hardness of the welded samples was measured. The strength of the welds was determined by the shear tests. It was observed that the shear strength of the welds depended on the welding time. The maximum shear strength was 210, 7 MPa.
