How do artists mitigate thermal distortion when welding aluminum figurative sculptures?
Welding aluminum figurative sculptures presents unique challenges, particularly thermal distortion, which can warp delicate details. Artists employ several strategies to minimize this issue. First, they use controlled heat input by selecting low-heat welding methods like TIG (Tungsten Inert Gas) welding, which offers precision. Preheating the aluminum evenly can also reduce thermal stress. Additionally, artists often weld in short, staggered sections to distribute heat and allow cooling between passes. Clamping or jigging the sculpture helps maintain alignment during welding. Finally, post-weld heat treatment or mechanical straightening may correct minor distortions. By combining these techniques, artists achieve stunning, distortion-free aluminum sculptures.
