LASER METAL DEPOSITION DEVICE AND METHOD

Patentradars sammanfattning

Procada AB's invention addresses process instability in laser metal deposition of wire (LMD-w) by introducing closed-loop force-feedback control. A multi-axis (XYZ) force sensor mounted at or near the wire nozzle measures real-time contact forces between the wire tip and substrate, and a controller drives a multi-axis actuator to reposition the wire nozzle relative to the laser beam accordingly. The controller can simultaneously adjust laser output power, wire heating current, and deposition traverse speed based on the same force data. This enables reliable deposition of very thin beads (sub-200 µm) by automatically detecting and correcting stubbing events and wire curvature-induced misalignment.
