Common Questions About the API API-577 Exam
The API-577 exam is the official American Petroleum Institute (API) exam behind the ICP Programs certification, validating the skills measured by the API Welding Inspection And Metallurgy credential. It sits at the Professional level of the American Petroleum Institute (API) certification program. It also connects to API 510 Pressure Vessel Inspector, API 570 Piping Inspector, API 653 Aboveground Storage Tank Inspector, so the knowledge you build here carries over to those tracks as well.
The API-577 exam contains 110 questions to be completed within 195 minutes. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the Lead2Passed test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.
Current API 510, API 570, or API 653 certification automatically qualifies a candidate. Otherwise, qualification is based on a combination of education and industry experience in welding inspection or related fields. Requirements can change when American Petroleum Institute (API) revises its certification program, so confirm the current eligibility rules on the official exam page before you register.
Yes. Lead2Passed provides a free API-577 PDF demo so you can review the question style and answer quality before purchasing. Every purchase also includes 365 days of free updates — if API revises the exam during that period, the updated material reaches you at no cost.
