Provided around a prechamber (41) is a magnetic shield (91) for the purpose of intensifying the magnetic blowing action on an arc formed between the arc guide rails (51, 61) of the prechamber. In addition, a blowing loop (81) is inserted in the arc-quenching circuit and extends in sections parallel to an arc guide rail (61). Prechamber insulation having a bulge constricting the arc area likewise serves the purpose of optimizing the arc run.Type: ApplicationFiled: December 9, 2004Publication date: July 14, 2005Applicant: ABB Schweiz AGInventors: Gerhard Schneider, Siegfried Mayer, Norbert Papok

Publication number: 20050150871Abstract: An apparatus and method arranged to use a combination of at least electrical resistance heating and mechanical friction heating to case a base material and/or a consumable material to reach a combination of temperature and pressure sufficient to cause welding. The method and apparatus configured for the simultaneous or substantially simultaneous application of both electrical resistance heating and friction heating to achieve welding is referred to as an electrofriction process, method or apparatus. This combination of resistance and friction heating allows the heating to be more localized within a relatively small weld zone, thereby improving the efficiency of the overall process and allowing the size, weight and strength and/or the cost of the application equipment and/or associated fixtures and power supplies to be reduced while enhancing its capability for operation in confined spaces and providing satisfactory welding performance.Type: ApplicationFiled: January 12, 2004Publication date: July 14, 2005Inventor: Henry Offer

Publication number: 20050150872Abstract: The invention relates to a protective covering for welding devices, in particular spot welding pliers, said covering being resistant to welding projections and being non-flammable. The inventive covering comprises a front panel and a rear panel which can be connected to each other by connecting means enabling the distance between the two panels to be adjusted, said panels being substantially planar and protecting the part of the device provided with welding pliers and the part opposite thereto, also comprising a tubular rim which is placed between the front and rear panels and which protects the part located between them, said rim consisting of several panels which are joined to each other in a non-detachable manner such that the rim corresponds substantially to the circumference of the welding device.Type: ApplicationFiled: April 14, 2003Publication date: July 14, 2005Inventor: Alain Robillot

Publication number: 20050150873Abstract: A drive device, especially for a pair of welding tongs comprising a pair of limbs, essentially arranged between the adjusting ends of the limbs, which are located opposite to the welding ends embodied with welding electrodes, for adjusting at least one limb between a welding position and a standby position. In order to improve said type of drive device in such a way that the construction length thereof is small, the drive device can be continuously controlled and monitored for the actuation of the welding tongs, the structure thereof is simple, economical and easy to maintain, and the noise of said drive device is significantly reduced, the inventive drive device is provided with an electric motor-driven screw-thread drive with a rotating nut and a rotating spindle which is axially displaceable between an extended and a return position, said spindle being movingly connected with the free extending end thereof to an adjusting end of the limb.Type: ApplicationFiled: February 5, 2003Publication date: July 14, 2005Inventors: Stefan Schmitt-Walter, Robert Hartmann

Publication number: 20050150874Abstract: A method of monitoring a resistance welding system is provided. The method utilizes a sensor for isolating and determining movement of a pin that typically supports an object to be welded such as a fastener. The movement of the pin is used to determine various present welding operation parameters to reduce cycle time, and increase efficiency and quality of the weld. The present welding operation parameters are compared to learned or stored welding operation parameters, for example, to determine whether a fault should be generated or whether an acceptable weld was achieved.Type: ApplicationFiled: December 1, 2004Publication date: July 14, 2005Inventors: Daniel Cabanaw, David Beneteau

Publication number: 20050150875Abstract: According to the present invention, a case housing a product and a lid made of material that transmits a laser beam are fixed to each other with a bonding member interposed between them, and thereafter, a laser beam is focused onto the bonding member through the lid so that the bonding member is melted. By doing so, the case and the lid are welded together via the bonding member.Type: ApplicationFiled: July 6, 2004Publication date: July 14, 2005Applicant: Seiko Epson CorporationInventors: Jun Amako, Kazushige Umetsu, Hideo Tanaya

Publication number: 20050150876Abstract: A plurality of stretches of laser weld are executed on a structure to be welded by means of a device for focusing and orientation of the laser beam, which is associated to a component element of a manipulator robot. The focusing head is kept in the proximity of, but not closely adjacent to, the different areas to be welded and can consequently follow a simplified path, whilst the device for orientation of the laser beam aims the latter on the different areas of the structure to be welded, so that the speed of travel of the laser beam spot along the longitudinal direction of the weld stretch is independent from the speed of travel of the robot end element.Type: ApplicationFiled: December 14, 2004Publication date: July 14, 2005Inventors: Roberto Menin, Arturo Baroncelli, Enrico Mauletti
