Abstract

Wire arc additive manufacturing (WAAM) is an effective method for fabricating lattice structure. The WAAM equipment of lattice structure, the design and fabrication technology of Al-based flux-cored wire, the laser constrained arc process and the diameter and angle control method of lattice rod were studied. Typical lattice structure application parts were manufactured. The WAAM equipment of lattice structure is composed of additive manufacturing unit, laser unit and monitoring unit. The Al-Cu-NiO alloy system of in-situ Al,2,O,3, phase Al alloy core wire was designed. The core wire with a diameter of 1.2 mm was prepared, and the deposition rod had low thermal conductivity. Laser excites a large number of neutral particles to ionize, so that the charged particles in the arc greatly increase the arc, which has a restraining and stabilizing effect on the arc and improves the forming accuracy. By controlling the volume and number of droplets in WAAM, lattice unit rods with different diameters of 2.5~7.0 mm can be manufactured. By controlling the lift and offset between the layers of the welding torch during WAAM process, lattice unit rods with different angles of 15°~90° can be prepared. The high-precision forming of planar lattice, cylindrical lattice and curved busbar lattice structures is fabricated by using the lattice structure WAAM technology. The average compressive strength of the lattice structure is 58.53 MPa. The uniform heat source is applied to the upper surface of the lattice test piece. The heat source temperature is 500 ℃. When the heat source is applied for 600 s, the lower surface temperature of the test piece is about 93 ℃, which has high bearing performance and thermal insulation performance.
