摘要： PROBLEM TO BE SOLVED: To provide a friction stir welding tool capable of satisfactorily performing friction stir welding on a weld zone.
SOLUTION: The friction stir welding tool 13 includes a shoulder part 13a having a round shoulder face 31 that imparts frictional heat to a workpiece, with a probe 13b provided in a hanging condition along the center axial line of the shoulder face. In the probe, a machining pattern is formed such that, on the upper side of the probe, stirring is performed in the probe circumferential direction parallel to the shoulder face and that, on the lower side of the probe, convection is produced downward. The shoulder face is a face orthogonal to the axial line and, in the shoulder face, there is formed a forced moving pattern of the frictional heat going from the outer circumference to the center relative to the shoulder rotating direction.

摘要： PROBLEM TO BE SOLVED: To perform joining in the state in which a base plate and a filler material can be easily aligned flat, eliminating a risk that the base plate and a groove line may deviate forward and backward or right and left, and releasing a softened area of the base plate from a risk of tear.
SOLUTION: The friction stirring and joining apparatus comprises a bottom pressing member, a top pressing member, and a bobbin tool 1 composed of the two pressing members which are connected together by a fixed or changeable mother plate stirring shaft (probe shaft) 12 or facing each other. Sliding faces for friction heat input contacting the mother plate have different diameters between the two pressing members. The bottom pressing member is connected to the stirring shaft 12, while the top pressing member is loosely fitted to the stirring shaft 12, and the rotational direction of the top pressing member is set in the reverse direction of the bottom pressing member. A fitting hole, which has a rotation control part and a axial direction control part on the inside periphery, is prepared at the starting point of the friction stirring. The friction stirring and joining is started after the bobbin tool 1 is fitted into the fitting hole, while the stirring shaft is attached with the filler material to be fitted into the fitting hole.

SOLUTION: A friction stir welding apparatus uses a bobbin tool having a back surface pushing member and a front surface pushing member, the distance between which is variable. The means for making the distance between both pushing members variable is composed of a plurality of pushing means. That is, the pushing means is composed of a first pushing means for raising the temperature up to at least a softening point and a second pushing means for carrying out the friction stir welding by generating the force higher than that of the first pushing means. The friction stir welding apparatus is characterized in that the first pushing means is a mechanical pushing means, and the second pushing means is a magnetostrictive means or an electromagnet attractive means.
