A method for supplying, positioning and processing fixing elements using a transport means which moves the fixing elements from a starting position to a processing position whereby the individual fixing elements are introduced into a chuck provided with two clamping jaws, are held by the clamping jaws in an engaging position and, once the chuck has been positioned, are taken up from this position by a driving element and the chuck presses them against a locating device and a connection is made to a component part by the driving element when the chuck is opened, wherein the upward motion of the chuck, while feeding the fixing element to the locating device, prevents the supply of further fixing elements to the chuck.

A device for holding a stud with a radially flange and an axial shank. The holding device comprising a collet including a clamping section and a hollow insertion section defining an insertion axis such that the stud can be inserted via the insertion section to the clamping section. The holding device further comprising a tubular securing sleeve located radially inward of and concentric with the insertion section. A clearance is defined between a bottom end of the securing sleeve and a top end of the clamping section and is adapted to releasably receive the stud flange. A first air flow channel in a first direction is adapted to blow feed the stud into the collet; and a second airflow channel oriented in a second different direction is adapted to maintain the stud shank substantially in line with the insertion axis.

A light module projects multiple light beams onto an installation surface to form multiple light indicia spaced apart in a pattern on the installation surface, with the light indicia identifying installation locations on the installation surface where construction mounts are then installed. Embodiments include systems in which the light module includes a light emitter that projects a source light beam and a diffractor that diffuses the source light beam into the multiple light beams, systems in which the light module is adjustably mounted to and movable with a handheld tool used to install the construction mounts, systems in which the light module is adjustably mounted to a static-use support, and methods of using these systems to install the construction mounts.

A Y-shaped refractory anchor, a plurality of Y-shaped refractory anchors, and a method of installing a plurality of Y-shaped refractory anchors in a hexagonal pattern is disclosed. The Y-shaped refractory anchor comprises a singular folded metal plate comprising a stem that comprises at least one triangular section to be welded to a backing surface and a folded stem base and a branch section comprising two branches, wherein the singular metal plate is folded together at the stem base, such that the stem of the Y-shaped anchor is twice as thick as the two individual branches.

An apparatus and method for forming a wear resistant stud for a vehicle. The method comprising providing an elongate threaded stud member having a top surface, locating a body of tungsten carbide on the top surface, surrounding the body of tungsten carbide with a weld pool and while the weld pool is hot, slowly cooling the weld pool. The apparatus comprises an elongate threaded stud member having a top surface, a body of tungsten carbide on the top surface and a weld pool surrounding the body of tungsten carbide and the top surface of the stud member wherein the weld pool is slowly cooled from a hot applied state

A stacked output structure of a capacitive power supply for welding equipment, having a plurality of capacitors to be connected in parallel, two electrodes of each capacitor are respectively provided with a pin including a long pin and a short pin; at least two PCB bus plates placed in stack are provided above the capacitor is provided. A lower PCB bus plate is connected with the short pin; and a pass-through hole is provided, at a position corresponds to the long pin, on the lower PCB bus plate. The long pin passes through the pass-through hole in the lower PCB bus plate and is connected with an upper PCB bus plate. There is a gap between the long pin and an inner wall of the pass-through hole.

A system and method is provided. The system includes a first power supply that outputs a welding current that includes welding pulse currents and a background welding current. The system also includes a second power supply that outputs a heating current that includes first heating pulse currents at a first polarity and second heating pulse currents at an opposite polarity. The system also includes a controller that synchronizes at least one of the first heating pulse currents and the second heating pulse currents with at least one of the welding pulse currents and the background current to influence a position of an arc relative to a molten puddle based on magnetic fields created by the welding current and the heating current.

The present disclosure teaches systems and methods for robotic welding of studs onto the surface of I-beams. These systems and methods will find industrial applicability in, for example, the steel erection industry.
