Abstract: A method of laser welding steel sheets that have a thin corrosion protective coating of zinc. The steel sheets are positioned vertically. A pulsed laser beam, which is positioned normal to the sheets is applied to the sheets to melt the material of the sheets and create a weld. During welding, the laser beam is pulsed ON and OFF and the sheets and pulsed laser beam are moved vertically relative to each other such that laser heating of the material creates a cavity. Liquid or molten material flows vertically downwardly by gravity to elongate the cavity and thereby facilitate the escape of zinc vapors from the cavity.

Abstract: Galvanized steel sheets or a galvanized steel sheet and a sheet of another metal are welded to each other by a laser beam. An intermediate layer for suppressing evaporation of zinc is formed between the galvanized steel sheets (1, 4) or the galvanized steel sheet (1) and the sheet of another metal. A laser beam (8) is applied to the galvanized steel sheet (1) or the sheet of another metal, thereby welding the sheets with the laser beam. As a result, porosity is prevented from being formed in a weld bead (9), and the weld bead (9) has a constant width.

Abstract: A transfer apparatus includes a transfer member, for example, a transfer drum with a line of small closely spaced laser drilled vacuum holes to hold a receiving sheet to the drum surface. To maintain the continuity of a transfer field but be free from clogging, the holes are narrow near the surface of the drum but wider as they extend deeper in the drum.Conical holes are drilled in the drum by a laser. In one embodiment, a short focal length lens focuses a laser bear near the surface of the drum which beam spreads below the surface to form a conical hole.

Abstract: A laser system and processing method exploits the absorption contrast between the materials from which a link (12) and an underlying substrate (22) are made to effectively remove the link from the substrate. Laser output in a wavelength range of 1.2 to 3 mu m (30) optimizes the absorption contrast between many materials (e.g., metals, polysilicon, polycides, or disilicides) and integrated circuit substrates (e.g., silicon, gallium arsenide, or other semiconductors) and permits the use of laser output in a wider range of energy or power levels, pulse widths, and spot sizes without risking damage to the substrates or adjacent circuit structures. Existing link processing laser systems can be readily modified to operate in the 1.2 to 3 mu m range.

Abstract: Upper and lower shell members of aluminum-plated steel panels have respective flanges overlapping each other and welded to each other by a laser beam, forming a fuel tank. One of the flanges has a stepped region spaced from the other of the flanges, defining a gap between the stepped region and the other flange. The laser beam is applied to the flanges closely to the gap for discharging unwanted components such as aluminum from a welded area of the flanges into the gap. Therefore, the amount of aluminum contained in the welded area is reduced to increase the bonding strength of the welded area.
