  • Patent number: 11213918
    Abstract: A weld is formed in a workpiece such as a pipeline by first activating a melting device, such as a laser, to form a molten weld pool in the workpiece and then activating a welding device, such as a GMAW torch, to initiate a weld in the weld pool. The weld therefore incorporates the weld pool homogeneously. Relative movement between the activated welding device and the workpiece continues and completes the weld while the melting device remains deactivated.

  • Patent number: 11148226
    Abstract: A method of laser spot welding a workpiece stack-up (10) that includes at least two overlapping steel workpieces (12, 14, 150) is disclosed. The method includes directing a plurality of laser beams (24, 24?, 24?) at the top surface (20) of the workpiece stack-up to create a molten steel weld pool (92) that penetrates into the stack-up. The molten steel weld pool is then grown to penetrate further into the stack-up by increasing an overall combined irradiance of the laser beams while reducing the total projected sectional area (88) of the laser beams at a plane of the top surface of the workpiece stack-up. Increasing the overall combined irradiance of the laser beams may be accomplished by moving the focal points (66, 66?, 66?) of the laser beams closer to the top surface or by reducing the mean angle of incidence (86) of the laser beams so as to reduce the eccentricity of the individual projected sectional areas of the laser beams.

  • Patent number: 10960603
    Abstract: A method, apparatus, and program for additive manufacturing. In one aspect, the method and program comprises forming an at least partially solidified portion within a first scan region by irradiating a build material at a first energy density value along a first irradiation path. A second at least partially solidified portion is formed within a second scan region that is spaced with respect to the first scan region, wherein the solidified portion within the first scan region is formed by irradiation a build material at a second energy density value along a second irradiation path. The space between the first scan region and the second scan region is at least partially solidified by irradiating a build material at a third energy density value that less than the first energy density value and the second energy density value.

  • Patent number: 10953497
    Abstract: A method of laser welding a workpiece stack-up (10) of overlapping steel workpieces (12, 14) involves heat-treating a region (64) of the stack-up (10) followed by forming a laser weld joint (66) that is located at least partially within the heat-treated region (64). During heat-treating, one or more pre-welding laser beams (68) are sequentially directed at a top surface (20) of the workpiece stack-up (10) and advanced along a pre-welding beam travel pattern (70) so as to reduce an amount of vaporizable zinc within the stack-up (10). Thereafter, the laser weld joint (66) is formed by directing a welding laser beam (82) at the top surface (20) of the workpiece stack-up (10) and advancing the welding laser beam (82) along a welding beam travel pattern (84) that at least partially overlaps with a coverage area of a pre-welding beam travel pattern (70) or a shared coverage area portion of multiple pre-welding beam travel patterns (70).

  • Patent number: 10953494
    Abstract: A method of laser welding a workpiece stack-up (10) that includes at least two overlapping metal workpieces (12, 14) comprises advancing a laser beam (24) relative to a plane of a top surface (20) of the workpiece stack-up (10) from a start point (84) to an end point (86) along a beam travel pattern (78) at a high laser beam travel speed of greater than 8 meters per minute. The two or more overlapping metal workpieces (12, 14) may be steel workpieces or they may be aluminum workpieces, and at least one of the metal workpieces (12, 14) includes a surface coating (40). Advancing the laser beam (24) along the beam travel pattern (78) forms a weld joint (76), which includes resolidified composite workpiece material derived from each of the metal workpieces (12, 14) penetrated by a molten weld pool (80), that fusion welds the metal workpieces (12, 14) together. The relatively high laser beam travel speed contributes to improve strength properties of the weld joint (76).

  • Patent number: 10946485
    Abstract: A method for welding two components is provided. The method includes providing a first component, which has a convex elevation, and providing a second component, which has a through-hole. The method also includes placing the two components one against the other such that the convex elevation of the first component protrudes into the through-hole in an interlocking manner, and welding the two components along the rim of the through-hole by way of a laser welding device. The welding is performed without the use of a welding filler and the laser welding device is repeatedly switched on and off in a pulsed manner during the welding of the two components along the rim of the through-hole.

  • Patent number: 10946479
    Abstract: A method of laser welding a workpiece stack-up (10) that includes at least two overlapping aluminum workpieces comprises advancing a laser beam (24) relative to a plane of a top surface (20) of the workpiece stack-up (10) and along a beam travel pattern (74) that lies within an annular weld area (82) defined by an inner diameter boundary (86) and an outer diameter boundary (84) on the plane of the top surface (20). The beam travel pattern (74) of the laser beam (24) surrounds a center area encircled by the annular weld area (82) on the plane of the top surface (20) so as to force entrained porosity inwards into a region of the weld joint (72) beneath the center area on the plane of the top surface (20) of the workpiece stack-up (10).

  • Patent number: 10888956
    Abstract: The present disclosure relates to a system for forming a material layer that may make use of an optical light source for generating an optical beam, and a beam shaping subsystem configured to shape the optical beam to generate a complex beam intensity profile. The complex shaped beam may be used to selectively melt at least portions of a bed of powder particles residing on a substrate during formation of the material layer, as the optical light source is moved. A computer may be used to control the optical light source. The complex beam intensity profile enables control over the microstructure of grains formed during melting of the powder particles as the material layer is formed.

  • Patent number: 10857624
    Abstract: While a laser-beam application position is moved along a locus which circularly or elliptically circles around a locus center so as to cross a weld line that is a boundary between a first metal plate and a second metal plate overlapped with each other, the locus center is moved in a direction parallel to a weld line. A moving direction of the laser-beam application position is set such that the laser beam is first applied to the first metal plate and then to the second metal plate when the laser beam passes through an unmelted zone of the first metal plate and the second metal plate. The unmelted zone is located downstream of a range through which the laser beam has already passed in the direction parallel to the weld line.
