Abstract

In this work, Aluminium AA7075-T6 to Carbon Fibre Reinforced Polymer (CFRP) tube joints using magnetic pulse welding technology were performed. The process was found suitable for joining this material combination when a rigid support is used to constrain the CFRP wall displacement. A minimum discharge energy of 2.5 kJ was seen to produce tight interfaces in tubular geometry for 1 mm of stand-off distance. A larger number of turns in the coil was found to reduce both the damages caused by the impact forces and to increase the joint axial resistance. To protect the CFRP tube from impacts and achieve a weld, an electrolytic Nickel coating was deposited over the CFRP tube. Welding was produced between the coating and the aluminium tube with no intermetallic compounds observed on the interface for the energies tested.
