Creating metal sculptures with interlocking parts requires a blend of artistic vision and technical skill. One of the most popular techniques is welding, which allows artists to fuse metal pieces seamlessly while maintaining structural integrity. Another method is riveting, where metal parts are joined using rivets, offering a sturdy yet decorative connection. Slotting, or the use of precisely cut grooves, enables pieces to fit together like a puzzle without additional fasteners. Forge welding, a traditional approach, involves heating and hammering metal to create interlocking joints. Lastly, cold connections like bolts or screws provide flexibility for disassembly and reassembly. Each technique offers unique aesthetic and functional benefits, empowering sculptors to bring intricate designs to life.
