Publication number: 20150174697Abstract: Providing a rotary tool for friction stir spot-welding, which makes it possible to join together two aluminum members superposed on each other, with a high degree of joint strength. The rotary tool has a probe which is provided in a central part of a distal end portion of a cylindrical tool body so as to extend coaxially with the tool body and which has a stepped structure consisting of an intermediate probe and a central probe which extend coaxially with each other. Distal end faces of the tool body and the intermediate probe respectively give a first shoulder surface and a second shoulder surface which are gradually recessed in a radially inward direction and connected to proximal portions of the respective intermediate and central probes.Type: ApplicationFiled: March 2, 2015Publication date: June 25, 2015Inventor: Toshihiko FUKUDA

Patent number: 9051633Abstract: An aluminum alloy material is welded by performing friction stir welding to form a welded section in an aluminum alloy welded component. The aluminum alloy material contains Mg: 0.3-6.0% (mass %, hereinafter the same), Cu: 0.2% or less, Si: 0.1% or less, Fe: 0.1% or less, the balance being Al and inevitable impurities. Second phase particles dispersed in the aluminum alloy material have a grain size of 5 ?m or less as observed with an optical microscopic. Because the second phase particles are homogeneously dispersed in a welded section equivalent portion of the aluminum alloy welded component as compared to other portions, variations in pit formation caused by etching during anodizing are reduced, thereby eliminating color tone variations in the anodized coating formed on the aluminum alloy welded component.Type: GrantFiled: October 8, 2010Date of Patent: June 9, 2015Assignee: SUMITOMO LIGHT METAL INDUSTRIES, LTD.Inventors: Yoshikazu Ozeki, Toshihiko Fukuda, Kenji Katou
