Certified Resistance Welding Technician
CRWT: Equipment and Procedure Confidence
CRWT: Equipment and Procedure Confidence
Resistance welding is a robust process employed in automobile and appliance manufacturing. It creates strong, long-lasting welds by combining heat, time, and pressure, using sophisticated, high-value equipment managed by skilled technicians and engineers.
One such professional is the Certified Resistance Welding Technician (CRWT), a certification co-developed by the American Welding Society (AWS) and the Resistance Welding Manufacturing Alliance (RWMA). This certification showcases a technician's expertise in resistance welding principles, processes, and equipment, achieved through relevant education, experience, and examination. The CRWT certification is valuable to individual professionals like welders, engineers, and quality control managers, and can also enhance the credibility and skill set of teams within companies operating in a resistance welding environment.
