ABSTRACT:
Welding head1for friction stir welding, adapted for connection and driving of a tool2intended for simultaneous friction stir welding from two opposite surfaces on an object for welding, comprising a tool holder9, a force-generating device3, 13and a rotary driving device5which, during operation, can impart to the connected tool2a cyclic movement around the centre axis10of the tool and relative to the object for welding arranged in conjunction with the welding head. The force-generating device is controllable during operation and adapted so as, during operation, to act between a primary shoulder6and a secondary shoulder7on a tool2connected in the tool holder9. The invention also comprises a welding system for friction stir welding, with the force between the shoulders of the tool being controlled depending on the current torque for rotary driving. Also indicated are a method for initiating friction stir welding and computer program for such a method.
