Unlike other welding processes, different types of materials can be bonded, as long as their hardness differences are not too great. As a rule the parts to be welded do not have to be pre-treated. In the case of aluminum sheet, the maximum thickness is approx.2 mm, otherwise there is no limit.Excellent results are possible with pure aluminum and copper,they can also be bonded with other metals, e.g. gold, silver, silicon, nickel etc.
The conventional ultrasonic metal welding process,either on a continual basis or linear has broad applications today, particularly in the electronics sector.
The linear ultrasonic metal welding process is also suitable for ring welds with relatively small diameters.
