High Frquency Induction jointing hammer

Induction jointing is a form of jointing that uses electromagnetic induction to heat the workpiece. 
The jointing apparatus contains an induction coil that is energised with a high-frequency electric current.

Induction jointing is used for long production runs and is a highly automated process, usually used for jointing the seams of pipes. It can be a very fast process, as a lot of power can be transferred to a localised area, so the faying surfaces melt very quickly and can be pressed together to form a continuous rolling joint.
