What materials can be welded using friction pulse bonding?


Friction pulse bonding (FPB) has been applied mainly to malleable materials such as copper and aluminium. These materials require less force and less deformation to achieve a joint. Harder/stiffer materials are more difficult and cause wear of the rotating, hardened steel wheel used in the process.

Using FPB, the weldability of a range of materials has been investigated. Results are summarised in the table:

Group 1: materials which are readily welded using FPBGroup 2: materials which are more difficult to weld using FPB
aluminium spring steel
copper aluminium to alumina
copper braid acetate film
copper track on printed circuit board polypropylene
copper wire to copper/polyimide flexible circuit high density polypropylene
PVC insulated copper ribbon cable PVC
