A method for welding a ball onto a first component includes the following steps: providing a first component; creating a physical mark in or on the first component; positioning the ball in the place where the physical mark has been created; and welding the ball in a non-contacting manner to the first component using a laser welding device that is positioned at a distance from the first component and the ball.

Methods of fabricating formed glass articles are described herein. In one embodiment, a method for fabricating a formed glass article may include forming a glass ribbon, forming a parison, and shaping the parison to form a glass article. The glass article may be attached to the glass ribbon at an attachment region defining an edge of the glass article. The process may also include contacting the attachment region with a focal line of a laser beam and separating the glass article from the glass ribbon at the attachment region. The attachment region may be perforated by the laser beam and the focal line may be substantially perpendicular to the plane of the glass ribbon.

An orthopedic device, such as an intramedullary nail for internal fixation of a bone and a method of manufacturing the same. The orthopedic device may be formed from a medical grade powder via an additive manufacturing process. The forming process may include heat treating the additive manufactured component and machining the heat treated additive manufactured component to form the orthopedic device. Further, the orthopedic device may be formed to include an internal sensor probe channel that extends within at least a portion of the wall of the device, but which does not protrude through an outer portion of the wall. Embodiments further include a dynamizing intramedullary nail that accommodate adjustments in the relative axial positions of one or more sections of the orthopedic device. The devise may include features in an inner region of the orthopedic device that may alter an elastic modulus of the orthopedic device.

A method and a related system of forming laser etched indicia on an external surface of the golf club. The method includes directing a laser beam onto a golf club head, and etching a prescribed indicia into the golf club head. The etching is generated by at least one of: (i) rotating the golf club head relative to the laser beam; and (ii) rotating the laser beam relative to the golf club head.

Disclosed is a method for removing a film from a substrate by irradiating a plurality of unit pulse laser beams to an edge region of the substrate. The method includes a first irradiation operation for irradiating a plurality of unit pulse laser beams onto the substrate while the substrate is rotating, and a second irradiation operation for irradiating a plurality of unit pulse laser beams to regions of the substrate onto which the unit pulse laser beams are not irradiated in the first irradiation operation.

A laser drilling system is configured with a combination of system components including a fiber laser source, laser processing head, dynamic compensator, configured with one or multiple galvanometers, and stage supporting the workpiece to be laser drilled. The system components are all functionally coupled to one another to provide a plurality of trepanned holes in the workpiece each with the desired geometry. The laser head and stage are continuously displaceable relative to one another while the dynamic compensator pivots so as to keep the laser spot and the predetermined drilling location stationary relative to one another over a predetermined period of time sufficient for drill the hole. The laser source is selected from solid-state lasers configured with a single core or multi-core delivery fiber. The multicore delivery fiber is associated with adjustable mode beam (AMB) lasers to provide annular, polygonal or irregular holes.
