A coaxial laser metal deposition head includes a wire guide and a plurality of laser optical units. The wire guide defines a wire guide axis. The laser optical units are distributed around the wire guide axis. Each of the laser optical units is connected to a separate laser and each defines...
Laser metal deposition with coaxial wire feeding is a directed energy deposition process that enables near-net-shape and direction-independent additive manufacturing of metal parts. However, the high sensitivity of the process to disturbances poses a major challenge, as this frequently leads to defectiv...
As a result, the coaxial jet provides a highly versatile system to study the interaction of non-spherical particles with vortical structures and its possible application to the fabrication of “high-tech” surfaces by controlled particle deposition. 5.2. Heat Transfer As mentioned in this review, ...
Other known planarization or mechanical forming techniques, for example, mechanical finishing such as mechanical machining, diamond turning, plasma etching, laser ablation, and the like, may additionally or alternatively be used. Through surface planarization, the total thickness of a given layer can ...
laser bonding and the like. A commonly used automatic wire bonder is modified to ball bond gold, gold alloy, copper, copper alloy, aluminum, nickel or palladium wires 166 to the substrate surface 164 as shown in FIG. 11. The wire preferably has a diameter of 0.001 to 0.005 inches. If ...
Finally, the virtual sensing methodology presented here can also be applied to other AM and more general materials processing techniques, such as electron beam and directed energy deposition additive manufacturing, but also laser and electron beam welding/cutting. Table 2. Summary of the metallographic...
