材質は熱伝導が大きくて硬度も高い銅合金である。The holding device 80 behind the welding torch 55 prevents the entire work 10 from floating from the backing seat 15. For this reason, it is not necessary to install as close to the welding torch 55 as the holding device 60 in front of the welding torch 55. However, even in this case, since the roll 82 is heated to a high temperature, it needs to be cooled. The roll 82 is provided with a concave portion at the center in the axial direction for preventing contact with the weld bead. The roll 82 includes the left and right works 10, 1

The end of the work 11 has a protruding portion 11a protruding to the outer surface side (that is, the tool 100 side of the friction stir welding). The thick portion 11a is inclined toward the inside of the work 11. The end of the work 11 is vertical. These two workpieces 11 and 11 are butted. Tool 10
Reference numeral 0 denotes a large-diameter round bar 101 and a small-diameter round bar 102 at the end thereof. The small-diameter portion 102 is inserted into the butted portion while rotating the tool, and is moved along the joining line. The lower end of the large-diameter portion, that is, the boundary between the small-diameter portion 102 and the large-diameter portion 101 is located outside the upper surfaces of the plate portions 11b, 11b of the work 11, and is located inside the protruding portions 11a, 11a. .
