Abstract
A method of welding two work pieces that define a connecting zone between them is described. A friction pin is fed at a starting point into the connecting zone and into opposite regions of the work pieces on both sides of the connecting zone. The friction pin is moved in a welding direction along the connecting zone resulting in the work pieces being welded. The friction pin is led out of the connecting zone after welding the work pieces. The friction pin is fed into a sacrificial element while lifting the friction pin.

A method of welding two work pieces that define a connecting zone between them, which comprises the steps of:
- feeding a friction pin at a starting point into the connecting zone and into opposite regions of the work pieces on both sides of the connecting zone;
- moving the friction pin in a welding direction along the connecting zone resulting in the work pieces being welded;
- leading the friction pin out of the connecting zone after welding the work pieces;
- and
- feeding the friction pin into a sacrificial element while lifting the friction pin.
