20100288736 | WELD STUD - A weld stud 10 comprises a weld flange adapted to be welded to a workpiece and a portion integrally formed with the weld flange. The flange has a surface to be welded. The surface includes a flattened annular portion of a predetermined radial width at an outer periphery thereof and a conical recess conically formed from the annular portion to the center thereof, so that only the annular portion is welded to the workpiece. | 11-18-2010 |
20110033260 | FASTENER ASSEMBLY FOR FASTENING A MEMBER TO WORKPIECE - A fastener assembly comprises a stud bolt including a bolt portion and a weld end to be welded to a workpiece, and a nut member to be screwed into the stud bolt. The nut member screwed into the stud bolt before welding is formed out of an electrically conductive material to allow the welding current to flow through the nut member into the stud bolt and weld the nut member to the workpiece while connected to the stud bolt. Then an attachment member is disposed on top of the workpiece, and the attachment member is fastened to the workpiece when the nut member is turned in the fastening direction. | 02-10-2011 |
20110278275 | ARC WELDING METHOD AND ARC WELDING APPARATUS - An arc welding apparatus welds a bracket held by a welding head to a pipe by arc welding. A hollow tubular member is provided in the bracket, which tubular member is formed in a hollow conical shape or funnel, so that the diameter thereof increases from the bracket to an open mouth therein. The open mouth of the tubular member of the bracket held by the welding head is pulled up from a condition of being in contact with the pipe, an electric arc is generated between the mouth of the tubular member and the pipe to effect melting, and the open mouth is pressed against the pipe, whereupon the bracket is welded to the pipe. | 11-17-2011 |
