Abstract: The invention relates to a method for preheating at least one working roll for rolling, involving phases of:



determining a target thermal expansion profile,
determining an effective mean temperature profile of longitudinal segments of the working roll and for determining a target mean temperature profile,
activating a plurality of inductors distributed along the working roll in order to reduce a difference between the effective mean temperature and the target mean temperature.

Abstract: The invention relates to a tool (1), intended for a friction stir welding station, the tool being capable of being rotated and including: a body (10), defining a transverse surface, forming a shoulder (11); a pin (12), extending, from the shoulder (11), along a longitudinal axis (Z), to an end (13), the pin (12) becoming slimmer between the shoulder (11) and the end, the distance between the end (13) and the shoulder (11) corresponding to a height of the pin (h).
