Friction Welding Machine
Friction Welding Machine is used for welding of copper to aluminium for manufacturing bi-metal cable lugs. It has a workhead assembly having a rotatable chuck for forcefully displacing the first workpiece into frictional engagement with the second workpiece. The workhead includes a shear mechanism having a shear tool mounted for selected displacement along the chuck's rotational axis. An industrial computer is used to control the machine and to store all weld data. Graphs are plotted for all important weld parameters against time during welding and these are stored for each and every weld. It is difficult to weld copper to aluminum as the oxide layer on the copper cannot be removed by the rubbing action alone. ETA Technology has developed a special purpose friction welding machine.
