Take an AHSS with at least 590 MPa of tensile strength for rolling to circular ring of a rim. Apply low heat input welding, such as the cold metal transfer (CMT) welding or the gas tungsten arc welding/tungsten inert gas arc welding (GTAW/TIG), at the junction of the rim to form a hollow cylindrical rim. Then perform hole expanding and spinning/roll forming operations to the rim. Take another AHSS with at least 980 MPa of tensile strength for pressing and forming a disk. Apply low heat input welding, such as cold metal transfer (CMT) welding, to the rim and the disk to produce a wheel.

Patent number: 8704123Abstract: A method of creating a positive substance joint between components (1,2) involves the provisioning of the components (1, 2) and placing them at a joining position in relation to one another such that they contact at least one joining point or are kept apart by a narrow joining gap. The components (1, 2) feature a locating device that forces the components (1, 2) to fit and interlock in their relative position at the joining point. The components (1, 2) are then joined by a positive substance joint.Type: GrantFiled: April 25, 2011Date of Patent: April 22, 2014Assignee: Hella KGAAInventor: Steffen Rosenkranz

Patent number: 8678265Abstract: Disclosed herein is a strip joining apparatus for pipe mill equipment. The strip joining apparatus cuts a trailing end of a preceding steel strip and a leading end of a following steel strip, and puts the cut surfaces of the two steel strips into contact with each other, and then welds them to each other. Particularly, a cutting blade of a first cutting unit and a cutting blade of a second cutting unit are inclined in the downward direction at predetermined angles relative to each other. Thus, the ends of the two steel strips, which are respectively cut by the cutting blades, define a ‘V’-shape groove. In this state, the cut ends of the two steel strips are put in close contact with each other and are welded to each other, so that the quality of welding of the junction between the thick strips can be enhanced.Type: GrantFiled: May 8, 2012Date of Patent: March 25, 2014Assignee: Baek Chun Precision Co., Ltd.Inventor: Nak Chun Baek

Patent number: 8608048Abstract: A method of room-temperature bonding a plurality of substrates via an intermediate member, includes: forming the intermediate member on a surface to be bonded of the substrate by physically sputtering a plurality of targets; and activating the surface to be bonded by an ion beam. In this case, it is preferable that the target composed of a plurality of types of materials is physically sputtered. Since the materials of the intermediate member are sputtered from the plurality of targets arranged in various directions from the surface to be bonded of the substrate, the intermediate member can be uniformly formed on the surface to be bonded. Further, since the intermediate member is composed of the plurality of types of materials, the room-temperature bonding of substrates difficult to bond together when an intermediate member is composed of a single type of material can be performed without heating and excessively pressing the substrates during bonding.Type: GrantFiled: May 6, 2011Date of Patent: December 17, 2013Assignees: Mitsubishi Heavy Industries, Ltd., National Institute of Advanced Industrial Science and TechnologyInventors: Takayuki Goto, Jun Utsumi, Kensuke Ide, Hideki Takagi, Masahiro Funayama
