Method and sealant for joints

A joint between one or more structural members (20,22) and an associated method are provided. The joint includes a friction stir welded joint or other connection between faying surfaces of the members, and an exothermically reacted sealant (28) disposed in an interface defined by the faying surfaces. The exothermic reaction of the sealant in the interface can be initiated before, during, or after joining the structural members such that the sealant at least partially seals the interface. The sealant can fill the spaces between the structural members to prevent the entry of chemicals, moisture, debris, and other substances, thereby reducing the likelihood of corrosion of the joint or structural members at the interface. Further, the sealant can form a bond with the structural members, thereby increasing the strength of the connection between the members.

Friction stir welding process to join two or more members in forming a three-dimensional joint

A three dimensional joint is formed by coupling (joining) a first structural member and a second structural member. This involves first aligning a first structural member to a second structural member. The first structural member has a channel with which to receive a portion of the second structural member. Once aligned, the first structural member and second structural member may be friction stir welded at the channel to plasticize the material adjacent to the channel of both the first structural member and the second structural member to form a friction stir weld joint. This allows three dimensional objects to be formed from the friction stir weld joined members as opposed to merely allowing the joining of flat two dimensional surfaces.

Method and apparatus for friction stir welding

Two members 10 and 20 are welded together by cutting a groove 41 having a determined cross-sectional shape using a cutting tool 60 along the abutted portion between the two members 10 and 20, inserting a filler member 30 substantially having the same cross-sectional shape to the groove so as to substantially eliminate the gap at the abutted portion, temporarily welding together the projections 12, 22 and the filler member 30, and thereafter, friction stir welding the members 10, 20 and the filler member 30 together completely using a rotary tool 81.

Friction stir welding method with prior welding of a buildup bead by using a buildup member

The invention provides a friction stir welding method with less weld defects upon welding a butted portion between a first member (80) and a second member (90). A first member (80) is butted against a second member (90), and then a round-bar buildup member is pressed against the upper surface of the butted portion and rotated to weld a buildup bead (35) thereon. The buildup bead (35) corresponds to a projection of the prior art friction stir welding method. Next, a pin (51) of the rotary tool (50) is inserted to the butted portion to perform friction stir welding. According to this method, the buildup bead (35) corresponds to a projection and fills the space formed to the butted portion, so a good weld joint is formed and the generation of defects is suppressed.
