Which CWI endorsement should you get?
Quick answer
Which AWS Certified Welding Inspector endorsement should I get?
It depends on your industry. Structural steel work points to the D1.1 endorsement, pipeline and oil-and-gas work points to API 1104, and refinery or power-plant piping points to the ASME Section IX plus B31.1 and B31.3 endorsement. If you are just starting out in general fabrication, you may not need any endorsement yet. This tool maps your industry to the right code, or tells you honestly to wait.
How the recommender works
Each endorsement maps to a welding code and a set of industries. Pick the closest match and the tool returns the endorsement or endorsements that unlock that work, the code each covers, and whether passing it can satisfy your 9-year recertification. The full comparison, with question splits and recert value, lives on the endorsement matrix.
