| Abstract Scope |
In Wire Arc Additive Manufacturing (WAAM), changing the height of a layer usually requires adjusting the machine's speed or the rate at which wire is fed. However, fluid dynamics create a problem: making a weld bead taller naturally makes it wider. This often leads to poor overlapping between tracks, uneven shapes, and unpredictable heat buildup. This research offers a mechanical solution instead of changing welding settings. We use "micro-meander" toolpaths that change shape to control how much metal is deposited. A specialized algorithm automatically adjusts the width and frequency of these small zig-zag patterns based on their location. This ensures the edges of each track line up perfectly. By separating the machine’s movement speed from the amount of metal being added, we keep the welding arc stable and the temperature consistent. This method allows for smooth surfaces and variable heights without the physical issues found in standard WAAM. |
