American Welding Society (AWS)-accredited testing facilities (ATF) play a huge role in maintaining the quality and standards of the welding industry. These facilities are authorized to conduct performance qualification tests for welders seeking AWS certification. At an ATF, individuals can demonstrate their welding skills through hands-on testing in various processes, including SMAW, GMAW, GTAW and FCAW, in accordance with AWS codes, such as the D1.1 for structural steel.
