The creation of metal sculptures, whether abstract or figurative, involves distinct technical approaches that shape their final forms. Abstract metal sculptures prioritize unconventional shapes and experimental techniques, often employing cutting, welding, and bending to achieve non-representational designs. Artists working in this style frequently use industrial tools like plasma cutters and angle grinders to create geometric or organic forms that challenge traditional perspectives.

Figurative metal sculptures, by contrast, require precise technical skills to represent recognizable subjects. These works often begin with detailed sketches or maquettes before metal fabrication begins. Techniques like repoussé (metal hammering), chasing, and careful welding are employed to create human or animal forms with accurate proportions. Many figurative sculptors use armatures or internal frameworks to support their compositions.

Both styles share common metalworking fundamentals but diverge in their execution. Abstract pieces allow for more improvisation in joining methods and surface treatments, while figurative works demand controlled craftsmanship to maintain anatomical correctness. The finishing processes also differ significantly - abstract sculptures often showcase raw metal textures, whereas figurative works may incorporate patinas or polishing to enhance realism.

Modern sculptors sometimes blend these approaches, using abstract techniques to interpret figurative subjects or incorporating representational elements into abstract compositions. Regardless of style, mastery of metal properties - from steel's strength to copper's malleability - remains essential for successful sculpture creation.
