Include the standard, position, material, and process for each certification. AWS format example: 'AWS D1.1 CW, 3G/4G position, Carbon Steel, GMAW.' This level of specificity helps employers immediately understand your qualification scope. Include the issuing body and expiration date — welding certifications typically expire after 6 months to 3 years depending on the standard.

Welding markets vary significantly: structural (bridges, buildings), pipe (oil and gas, power generation), aerospace (high-tolerance materials), shipbuilding, and manufacturing each have specific code and process requirements. Identify the industry you're targeting and use its specific terminology — pipe welders cite API 1104; aerospace welders cite AWS D17.1.

Note quality standards you've worked under (AWS, ASME, API) and any non-destructive testing (NDT) exposure. If you've maintained low or zero defect rates on certified work, quantify it. 'Maintained less than 0.5% weld rejection rate over 1,200 certified weld joints on pipeline project' signals consistent high-quality output.
