The welding pin is suitable for a joining arrangement for the aligned joining of structural parts. | 05-09-2013 |
20130259597 | WELD STUD - A welding stud including a head and a shank extending from the head. The shank has an end region opposite the head and the end region includes at least two angled surfaces which incline towards an axis of the shank in a direction moving away from the head. | 10-03-2013 |
20140219740 | COMPONENT TO BE INSERTED THROUGH THE SURFACE OF A WORKPIECE - A component for use with a rotary tool is designed to be inserted through a surface of a workpiece made of a first material showing friction-induced plasticity for attachment to the workpiece. The component has a head portion having a base and a working end being threaded at its outer surface, and further has an insert portion having a penetrating end and extending along an insertion axis. At least an outer surface of the insert portion is made of a second material harder than the first material. The insert portion is provided with a threaded bore closed at its penetrating end and extending along the insertion axis to initially receive the threaded working end. The head portion base is adapted to be secured to the rotary tool for rotation in a first direction while applying an axial force of a sufficient magnitude onto the head portion base to produce substantially full insertion of the insert portion along the insertion axis by plasticizing the first material through friction and to produce attachment after a sufficient setting time. | 08-07-2014 |
20150337886 | SELF-LOCKING MOLDED-IN BLIND INSERTS - Blind inserts for use with sandwich panels and methods for manufacturing the same. A blind insert can include a nut arranged in an insert. The insert can include a cavity at an end of the nut. When a screw is screwed into the nut, the screw can enter the cavity and dig into the insert. The interference between the insert and the screw can provide friction that prevents the screw from loosening in a vibrating environment. The blind insert can be made by placing a mandrel into the nut. The mandrel includes a nose that extends past the end of the nut. When the insert is molded around the nut, the mandrel prevents mold material from entering a threaded aperture of the nut and forms the cavity in the insert. The blind insert can also be made by placing a cap that defines the cavity on the end of the nut. The insert can be molded around the cap and the nut. | 11-26-2015 |
20160040706 | ARC WELD STUD HAVING A FORMING THREAD - An arc weld stud for fastening a member to a structure with an unthreaded nut includes a weld end having an ignition tip, and a threaded portion defined by a thread configured to form a corresponding counter-thread into a smooth bore of the unthreaded nut, wherein the arc weld stud comprises a material that is harder than the material of the unthreaded nut. | 02-11-2016 |
