20100176093 | METHOD OF SHORT-TIME STUD JOINING - The invention relates to a method of short-time stud joining, a first workpiece, such as a stud for example, being joined with its end face onto a joining surface of a second workpiece, such as a metal sheet for example, with the steps of: a) creating an arc between the end face and the joining surface in order to begin melting the end face and/or the joining surface, and b) lowering the first workpiece onto the second workpiece and switching off a joining current (I | 07-15-2010 |
20100276400 | FRONT LOADING STUD WELDING HEAD - The invention relates to a joining head arrangement for joining components, such as studs, onto a workpiece. The joining head arrangement comprises a housing and a slide that is mounted on the housing and is movable, by means of a linear drive, in a joining direction in relation to the housing. The joining head further comprises a component holder, arranged on the slide, and operable to hold a component during a joining operation. A feed device delivers components, at a transfer location, to the component holder. The component holder is rotatable about an axis, which is aligned transversely relative to the joining direction, from a transfer position to a joining position. | 11-04-2010 |
20100288735 | METHOD AND APPARATUS FOR DETERMINATION OF ELECTRICAL WELDING CIRCUIT VARIABLES - A method for determination of electrical variables of a welding circuit which is connected to an electrical power supply device and operable to provide either a welding current or a lesser pilot current, the method including the steps of (a) determining the resistance of the welding circuit and (b) determining the inductance of the welding circuit. | 11-18-2010 |
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 |
