Properties of Cold Pressure Welded Aluminium and Copper Sheets

摘要：

Cold pressure welding has been used as an industrial process with an increasing rate for several years.In this study,cold pressure welding has been applied to aluminum and copper alloy sheets having commercial purity.Hydraulic press having 150 metric-ton capacities has been used for welding process.As the surface roughness and the weld deformation ratios of aluminum sheets increased,tensile strength of the joints also increased.Purchased specimens with original roughness had the lowest weld deformation as-is and it was not possible to join these sheets at 30％ weld deformations.Hardness increases due to local hardening at the interface as a result of cold deformation.Results showed that the cold pressure welding technique in lap form resulted in strong AlAl joints and the intermetallic layer formed in Al-Cu joints did not affect the joint strength to a great extent.
