It is aimed at welding professionals moving into supervisory roles, experienced welders who want to strengthen their grasp of efficiency, quality control, and safety, manufacturing and construction personnel responsible for welding operations, welding educators broadening their credentials, and business owners or managers improving welding quality and compliance. Eligibility requires a high school diploma or a state or military approved high school equivalency diploma, plus welding work experience: at least three years of practical welding work in a fabrication, construction, or welding-related industry, or at least two years of such work combined with three years of teaching experience in welding or related subjects.
