Electromagnetic impact welding of copper-to-copper sheets


Copper (Cu) has some properties, similar to aluminium (Al), like high thermal conductivity, high thermal expansion coefficient, relatively low melting point, brittleness at elevated temperatures and less viscosity of molten metal. These properties make the welding of Cu and Cu alloys difficult as compared to welding of carbon steels. The present study investigates the feasibility of electromagnetic impact welding of Cu-to-Cu sheets by using Al as the driver sheet. A study has been carried out to characterize the electromagnetic impact welding of 0.5 mm thick Cu sheets. The results of the microstructure and tensile shear strength tests are reported.
