Abstract: A surface treatment system includes a holder configured to secure an object within the holder and a surface treatment device that is configured to treat a surface of the object within the holder with two types of surface treatments. The device is capable of producing a plasma or a flame at its nozzle for surface treatment. By controlling the materials supplied to the device and the way in which is operated, either a flame or plasma is produced. Thus, the surface treatment system is capable of treating a wide range of materials for printing by a direct-to-object printer.

Abstract: The shaping precision is improved without performing finishing processing. A three-dimensional laminating and shaping apparatus includes a material ejector that ejects a material of a three-dimensional laminated and shaped object onto a shaping table on which the three-dimensional laminated and shaped object is shaped, a light beam irradiator that irradiates the ejected material with a light beam, a cutter that cuts a bead formed when the material irradiated with the light beam is melted and solidified, and a controller that controls ejection of the material by the material ejector, irradiation with the light beam by the light beam irradiator, and cutting of the bead by the cutter. The cutter cuts an upper surface of the bead by a dimension which is smaller than a laminating height and is ½ or less of a bead thickness.

Abstract: A process for identifying existence of a welded spot on a cut-out part and retention of the cut-out part on a workpiece in a wire electrode is disclosed which makes it possible to go ahead process steps while identifying automatically the retention of the cut-out part on a workpiece, ensuring unmanned work of the wire electrode discharge processor. The process includes an inspection step to detect whether the wire electrode comes into contact with a welded spot while moving the wire electrode along the cutting path of kerf in the workpiece, after the wire electrode has come into contact with the welded spot, a step goes ahead to one of next procedures, and after the wire electrode has come into no contact with the welded spot, a step goes ahead to generate an alarm and the wire electrical discharge is ceased.

Abstract: A welding system comprises a two manipulators and a controller. A first manipulator has a joint detection device and a first welding device, usually of the laser type while the second manipulator has a second welding device, usually of the arc weld type. The joint detection device is operative to read welding joint characteristics along a welding joint. The controller determines a corrected trajectory based on a predetermined welding trajectory and on the welding joint characteristics read by the joint detection device. This corrected trajectory is transmitted with a first time delay to the first manipulator and with a second time delay to the second manipulator. The second time delay is a function of a distance between the joint detection device and the second welding device. A corresponding method for welding components along a welding joint is also disclosed.
