Inspector

What Inspectors Do

Welding inspectors evaluate welds and welding processes to confirm they meet specific codes, standards, and specifications. They inspect completed welds for size, quality, and conformance to requirements. Inspectors review welding procedure specifications (WPS) and welder qualifications to ensure compliance with industry codes such as AWS D1.1, ASME Section IX, and API standards. They perform visual inspections and use non-destructive testing (NDT) methods to detect defects or problems. Inspectors document inspection results and generate detailed reports for management and clients. They advise welders and supervisors on quality issues and corrective actions needed to meet standards. Welding inspectors work in manufacturing facilities, construction sites, shipyards, power plants, oil and gas operations, and other locations where welded joints are critical to performance and safety. They ensure public safety by preventing costly failures and maintaining quality assurance standards.

Education Required

To become a welding inspector, candidates need a combination of welding experience, technical knowledge, and certification. Requirements include a high school diploma plus significant welding experience: five years of welding-related work experience with a high school diploma, two years with an associate's degree in welding technology or engineering, or one year with a bachelor's degree in welding engineering or technology. The most important credential is becoming an AWS Certified Welding Inspector (CWI), which requires passing a comprehensive three-part examination covering fundamentals, practical skills, and code knowledge. Inspectors must also have strong visual acuity, attention to detail, analytical skills, and good communication abilities. Additional certifications in non-destructive testing (NDT) are often beneficial for career advancement.
