Structural Welding Special Inspector S2 The S2 credential focuses exclusively on structural steel inspection protocols, whereas general welding inspector certifications cover broader fabrication contexts. While AWS D1.1 foundations matter for both, S2 demands specialized knowledge of load-bearing joint defects, fracture mechanics, and code compliance unique to buildings and bridges. Inspectors pursuing S2 gain narrower but deeper expertise than entry-level welding certifications.
