Abstract: A laser welding method and a laser welding device is provided. The laser welding device is configured to weld workpieces stacking multiple using a laser. The laser welding device includes a first laser irradiator and a driving device configured to enable one of the first laser irradiator and the workpiece to move relative to the other one of the first laser irradiator and the workpiece. A laser irradiation angle of the first laser irradiator is configured to be located on a side opposite to a welding proceeding direction. Through adjusting a height of the first laser irradiator relative to the workpiece, the first laser irradiator irradiates the laser to the workpiece in a focused manner.

Abstract: This invention relates to a method for manufacturing a metal part which comprises attaching a powder forged or wrought outer raced ID splined plate to a powdered metal inner splined connection gear, wherein the outer raced ID splined plate incorporates a female ID profile on the race, wherein the inner splined connection gear contains a mail OD profile on the exterior of the part, and wherein the splined plate and the splined connection gear are attached together by (1) sinter brazing, (2) laser brazing, (3) laser welding, (4) sintering a mechanical joint, or (5) staking. In practicing this method a tight mechanical joint is formed between the splined plate and the splined connection gear which can be made of highly dissimilar materials, such as a wrought metal and a sintered powder metal.

Abstract: Methods for welding materials such as superalloys, hard-facing materials, and aluminides that are difficult to weld without cracking. Instead of welding one layer at a time on the weld surface like existing methods, the weld comprises stacks of weld beads that are first built up vertically to a desired weld height. After a first stack is produced, the weld surface is translated relative to the filler material source and a second adjacent stack is produced. The process is repeated, traversing the weld surface. The stacks are preferably deposited at an angle to the filler material deposition direction. By building the thickness of the weld first, the heat of welding is preferably concentrated into a sufficiently small area on the weld surface so that weld pre-heating is not required, and each portion of the weld and weld surface undergoes only one heating and cooling cycle, reducing cracking.

Abstract: Systems and methods of a laser welding device are disclosed. The laser welding device includes a laser generator configured to generate welding-type lasing power. A lens focuses the welding-type lasing power at a focal point on a workpiece to generate a puddle during a welding-type operation. A wire feeder is configured to feed wire to the puddle generated by the laser generator. A laser scanner controls the lens to move the focal point of the welding-type lasing power in multiple dimensions over the workpiece during the welding-type operation. In some examples, the feed wire is used in an additive manufacturing process.
