What is CWI: Certified Welding Inspector?
CWI, or Certified Welding Inspector, is a designation earned by those who have met specific qualifications in welding inspection and quality control. CWI’s are often employed by welding contractors, manufacturers, and other organizations that utilize welding in their operations.
The duties of a CWI include ensuring that welders are qualified for the work they are performing, inspecting welds for defects, and maintaining records of welding inspection activities.
To become a CWI, one must first meet certain requirements in education and experience. A minimum of a high school diploma or equivalent is required, along with at least three years of welding experience OR two years of welding experience and an Associate’s degree in welding technology or related field.
In addition, candidates must pass a written examination administered by the American Welding Society (AWS).
