The API-577 exam leads to the Welding Inspection and Metallurgy Certification certification, a Specialist-level credential from API. It validates the skills measured by the API Welding Inspection And Metallurgy syllabus and is a recognized step for IT professionals building their careers, and it sits alongside related credentials such as API 510 Pressure Vessel Inspector, API 570 Piping Inspector, API 653 Aboveground Storage Tank Inspector.

The API Welding Inspection And Metallurgy exam includes 110 (100 scored, 10 pre-test) questions and gives you 195 minutes to complete them. That works out to a fairly tight pace, so reading each question carefully but decisively matters more than perfectionism. If a question stalls you, flag it and move on; banking the easier points first keeps time pressure from snowballing near the end. Before test day, run at least one full timed session with the ExamPrepAway practice test so the rhythm feels familiar rather than rushed.

You need Scaled score, approximately 70% to pass the API-577 exam, and the official registration fee is $440 USD. Keep in mind that a failed attempt means paying the full fee again to retake the exam, so it pays to be honest with yourself before booking a seat. A practical benchmark: work through the 112 practice questions at ExamPrepAway until you can score comfortably above the passing line in timed mode, then schedule your exam.
