Design and manufacture of an impact–electric current discharge joining machine

An impact–electric current discharge joining machine, which can simultaneously apply impact load and electric current, has been designed and manufactured to produce a high-strength joint between materials with little change in their appearance. The objective functions of the designed and manufactured impact–electric discharge machine are almost satisfied. Partial joining is achieved between FCD450/FCD450 samples and between FCD450/Al samples and the joints exhibit low fracture stress. Process parameters can be controlled to improve joint strength, by adjusting the setting values of the functions provided in the machine.
