A perforation system is disclosed that utilizes an optical beamlet generator and a scanner (e.g., at least two moveable mirrors). The optical beamlet generator may be a lenslet array or a diffractive optical element. The optical beamlet generator outputs a plurality of beamlets from a single input laser beam. These beamlets are moved in at least two dimensions relative to a surface of a substrate to form perforations in the substrate.

Substrate perforation system and method using beamlets

An assembly is provided for induction welding. This induction welding assembly includes a fixture. The fixture includes a first support structure and a second support structure. The second support structure includes a frame and a plurality of trunks. Each of the trunks is connected to and repositionable on the frame. The fixture is configured to secure a workpiece vertically between the first support structure and the second support structure using the trunks during induction welding of the workpiece.

Fixtures and methods for induction welding

Various arrangements and methods are disclosed for forming one or more perforations on a substrate surface using a laser system, at least one rotating polygon mirror, and at least one other movable mirror. A rotating polygon mirror may be used to define a plurality of perforations in a row set or band on a substrate surface by incrementing (e.g., moving) a first mirror between a plurality of fixed (e.g., pointing) positions. A rotating polygon mirror may be used to define a plurality of perforations in a row set or band on a substrate using a first mirror that is maintained in a fixed (e.g., pointing) position. A first rotating polygon mirror and a second rotating polygon mirror may be used to define a plurality of perforations in a row set or band on a substrate surface, where the first and second polygon mirrors are used to define an extent of a given perforation in two dimensions on the substrate.
