A deflection back and forth of the pulsed laser beam directed transversely or parallel to the feed direction is superposed on the pulsed laser beam moved in the feed direction. | 2021-01-14 |
20210008665 | METHOD FOR WELDING COATED STEEL PLATES - The disclosure relates to a method for welding steel sheets made of steel materials coated with an aluminum silicon anti-corrosion layer, in particular CMnB and CMn steel materials that can be hardened using the quench hardening method, wherein a welding filler rod is used in the welding of the sheets and the welding filler rod has the composition: C=0.80-2.28×% C base material, Cr=8-20, Ni<5, Si=0.2-1, Mn=0.2-1, Mo<2, with the rest being composed of iron and unavoidable smelting-related impurities and with all indications expressed in % by mass. | 2021-01-14 |
20210008666 | LASER-ARC HYBRID WELDING APPARATUS - A laser-arc hybrid welding apparatus includes a laser torch and a welding torch. The laser torch includes a DOE. The DOE enlarges a laser irradiated region in a direction of width of welding as compared with irradiation without the DOE and adjusts a shape of the irradiated region to allow a distribution in the width direction, of a quantity of heat input by laser to exhibit a prescribed profile. The prescribed profile refers to such a profile that a central portion in the width direction is not larger in quantity of heat input than an end in the width direction. | 2021-01-14 |
20210008667 | METHOD FOR LASER CARVING OF PAINT ON AN OUTER SURFACE OF A VEHICLE WHEEL - A method for laser carving of paint on an outer surface of a vehicle wheel includes a step of priming: priming an outer surface of the wheel to form a painted surface; a step of laser carving: carving the primer from a selected area of the wheel by laser to remove the painted surface from the selected area, the selected area having an exposed area with metallic luster, and a step of fine-polish: polishing the outer surface of the wheel to form a fine-polished area at the exposed area. The painted surface on the wheel can be quickly removed to disclose a selected area with metallic luster, while the wheel is prevented from corrosion so as to reduce manufacturing cost and increase precision. | 2021-01-14 |
20210008668 | LASER PROCESSING METHOD - A laser processing method includes a step of irradiating a workpiece, in which a metal layer made of a heat-resistant alloy and a protective layer made of a thermal barrier coating are laminated, with a first laser beam that is a short-pulse laser beam, and forming a through-hole penetrating the metal layer, and a step of irradiating the workpiece with a laser beam to expand the through-hole. | 2021-01-14 |
20210008669 | Abrasive Preforms and Manufacture and Use Methods - A method for applying an abrasive comprises: applying, to a substrate, the integral combination of: a self-braze material; and an abrasive embedded in the self-braze material; and securing the combination to the substrate. | 2021-01-14 |
20210008670 | Solder Alloy for Power Devices and Solder Joint Having a High Current Density - A solder joint which is used in power devices and the like and which can withstand a high current density without developing electromigration is formed of a Sn—Ag—Bi—In based alloy. The solder joint is formed of a solder alloy consisting essentially of 2-4 mass % of Ag, 2-4 mass % of Bi, 2-5 mass % of In, and a remainder of Sn. The solder alloy may further contain at least one of Ni, Co, and Fe. | 2021-01-14 |
