In some embodiments, the hole may be reshaped prior to inserting the plug. For example, the hole may be drilled out and/or a countersink may be created on one or both ends of the hole. Furthermore, the plug may extend outside of the hole prior to its reshaping and, in some embodiments, even after reshaping.

  • Patent number: 10369748
    Abstract: A method for solid state joining of dissimilar materials using a friction stir welding device wherein a pin is inserted through an aperture defined in a first material and a second material to hold the materials together and then held in place by friction stir welding a portion of the pin to a material adjacent said pin, or by friction stir welding a cap or plug that holds the pin in place to the adjacent material. The result is a connection or join wherein the central portion of the pin is not friction stir welded but the portions holding the pin in place (the ends or caps) generally are.

  • Patent number: 10335895
    Abstract: A friction stir welding device includes: a control device which causes a pin part to be inserted into members to be joined while causing a joining tool to rotate and which causes a joining head to move along a joint line via a robot main body; and an image pickup device which detects a junction deviation that is a deviation between the joining head and a direction along the joint line. Also, when a junction deviation is generated, this control device causes the joining head to move in a direction toward the joint line and thus resolves the junction deviation.
