摘要

Task Friction stir welding that controls the temperature difference between AS (Advancing Side) and RS (Retrieving Side) at friction stir welding according to the state of the members to be joined and the joining conditions and enables high quality (high precision) joining Apparatus and friction stir welding method. SOLUTION: A welding tool comprising a shoulder portion and a probe portion and inserted in the member to be joined and rotating, a device main body for holding the joining tool, a control device for controlling the operation of the joining tool, an AS A first temperature sensor for measuring the temperature of the material to be joined (advancing side), and a second temperature sensor for measuring the temperature of RS (retrieving side) of the member to be joined, Wherein at least one of a rotational speed and a traveling speed of the welding tool is controlled based on a joining temperature measured by the first temperature sensor and the second temperature sensor.BACKGROUND OF THE INVENTION
