摘要
Certain embodiments relate to a heat exchanger plate capable of performing friction stir welding at a deep position of the heat exchanger plate, and improving air-tightness and water-tightness. A method may include a lid groove closing process to insert a lid plate into a lid groove formed at a periphery of a concave groove opening to a surface of a base member. The method may also include a primary joining process to perform friction stirring while relatively moving a primary joining rotary tool equipped with a stirring pin along a butting portion of a side wall of the lid groove and a side surface of the lid plate. In the primary joining process, the rotating stirring pin may be inserted into the butting portion, and the friction stirring may be performed in a state of only the stirring pin being in contact with the base member and the lid plate.
