Latest Patents

Jiejie Xu's latest patents include a "Method and system for laser additive manufacturing based on keyhole effects." This patent describes a method where a welding wire and a laser beam are positioned at specific angles relative to a substrate. The laser beam generates a deep penetration melting keyhole, allowing the welding wire to absorb energy and melt in a deep penetration mode. This process facilitates the formation of a cladding layer on the substrate's surface.

Another notable patent is the "Micro-region semi-solid additive manufacturing method." This method utilizes rod-shaped materials as consumables, which are heated to a semi-solid state using high-energy beams or electric arcs. The consumables undergo shearing, agitation, and extrusion to create metallurgical bonding with the underlying metal. This innovative approach allows for the formation of objects or stack layers in unique shapes.
