Creating metal sculptures with modular components involves a blend of artistic vision and technical skill. One of the most popular techniques is welding, which allows artists to fuse metal pieces seamlessly, creating durable and cohesive structures. Another method is bolting, where components are joined using nuts and bolts, offering flexibility for disassembly or rearrangement. Interlocking systems, such as tabs and slots, provide a secure yet reversible connection, ideal for dynamic or transportable artworks.

Casting is also employed, where individual modules are molded and later assembled into the final sculpture. Additionally, some artists use riveting or adhesive bonding for specific aesthetic or functional needs. Each technique offers unique advantages, from the permanence of welding to the adaptability of bolted designs, enabling artists to explore endless creative possibilities in modular metal sculpture.
