    Abstract: A method of welding metal components (24, 26) together including moving a laser beam (20) in a first direction (A) along an interface (22) between a pair of metal components such that in the vicinity of the focused beam, metal from each component is vaporized to produce a keyhole (28) in a pool of molten metal (30). The laser beam (20) is oscillated in a direction (B) different from (e.g., transverse to) the first direction (A) such that the keyhole (28) oscillates through the pool of molten metal (30) and molten metal (30) fills into the keyhole (28) as the position of the keyhole (28) changes.

    Abstract: Portable friction stir welding apparatus having a crawler (200) which supports a motor (308) for rotating a Friction Stir Welding tool (213) and is coupled to a drive mechanism for urging the crawler along a predefined weld path on work pieces. The crawler can comprise one member (201) or a set of two or three physically separated members (201, 202, 203) each rotatably coupled to the friction stir welding tool. When one member is used to make a weld, it is located on top of the work pieces. When two members are used to make a weld, one member is located on the top of the work pieces and the second member is located on bottom of the work pieces. When three members are used to make two welds simultaneously on an upper work piece and a lower work piece, one member of the crawler is located on the top surface of the upper work piece, a second member is located between the two work pieces, and a third member is located on the bottom surface of the lower work piece. The friction stir welding tool for making the weld is rotatably coupled to each member and restricts axial displacement of the physically separate members relative to each other. The members are adapted to engage rails on the work pieces which provide at least one of guiding, alignment, fixturing, torque compensation for the members as the friction stir welding tool is rotated and the crawler is moved along a joint.

    Abstract: Structural connectors (500) for watercrafts, buildings and aircrafts are disclosed. In general, each structural connector includes at least a pair of members (510A, 512A) extending outwardly from and substantially perpendicular to a body (502) of the structural connector, the members spaced apart from one another so as to form a recess (514A) therein between. In some embodiments, the recess may be sized and shaped for receiving supporting members (550) including the likes of stringers and support plates.
