摘要

Lap-joints of SPCC (steel)/6111-T4 (aluminium alloy) were fabricated using the magneticrnpressure welding method. Interfacial microstructures between SPCC and 6111 plates andrntensile properties of the weld joint were examined. The duration required for the presentrnwelding was less than 100 μs. This resulted in very little microstructural change in thernparent plates except for the vicinity of the weld interface. Characteristic wavy interfacernmorphology and formation of intermetallic compound layers were observed at the weldrninterface. Strong lap-joints were obtained and no tensile fracture took place in the weldrnregion when the adequate welding condition was selected.
