  • Patent number: 9193320
    Abstract: An impact absorbing member is formed by bending one sheet of a metal plate material and then joining adjacent end parts thereof. The impact absorbing member includes the following integrally-connected portions: a fixing plate, an impact absorbing part having two first side wall plates and two second side wall plates, two flange plates, and two bridge plates. The impact absorbing part overall has an approximate square or rectangular tube shape after being bent. Joining parts are provided at each opposing end parts of the first and second side wall plates. The adjacent end parts of the first and second side wall plates overlap and are joined. The end parts of the two flange plates are also joined to the end parts of the two bridge plates.

  • Publication number: 20090250144
    Abstract: A method of joining heat-treatable aluminum alloy members by friction stir welding, including the steps of: a T4-treatment-performing step of performing a T4 treatment on heat-treatable aluminum alloy members so as to impart T4 temper to the heat-treatable aluminum alloy members; a joining step of joining the heat-treatable aluminum alloy members with T4 temper by friction stir welding to provide a joined product; and a reversion-treatment-performing step of performing a reversion treatment, the reversion-treatment-performing step being carried out prior to or after the joining step.

  • Patent number: 6921010
    Abstract: Method of joining together two planar members, by a friction stir welding operation wherein a rotary tool having a probe is moved relative to a joint region defined between the mutually butted planar members such that the probe is rotated and inserted in the joint region. The welding operation is performed by using a tab plate having a cutout formed in its end face such that the cutout has a width not smaller than a radius of a peripheral circle to be described by the shoulder surface, and a depth not smaller than a minimum radius of the probe and not larger than the radius of the peripheral circle.

  • Patent number: 6892928
    Abstract: Method of manufacturing a tubular end product, wherein an aluminum plate is formed into a generally cylindrical body such that opposite end sections of the cylindrical body are flattened and butted together along a joint region extending parallel to an axis of the cylindrical body, and such that each of the opposite flattened end sections has a predetermined width L as measured normal to the joint region, and the opposite flattened end sections are joined together at the joint region, by a friction stir butt welding operation wherein a rotary tool having a circular shoulder surface and a probe extending from the shoulder surface is moved relative to the cylindrical body while the shoulder surface is in rubbing contact with the flattened end sections, with the probe being rotated with the rotary tool and inserted in the joint region.
