The API Welding Inspection And Metallurgy blueprint spans 9 domains — including Metallurgy, Terminology and Symbols, Refinery and Petrochemical Welding Issues. Read the weightings as priorities: the points concentrate where the percentages do. The full outline above covers every subtopic.
The API Welding Inspection And Metallurgy is API's exam for the ICP Programs certification, a Professional-level credential. It's a hot topic because certified candidates stand out in job competition — the credential opens possibilities that uncertified resumes can't. Related credentials include API 510 Pressure Vessel Inspector, API 570 Piping Inspector, API 653 Aboveground Storage Tank Inspector.
Delivery is instant: payment triggers an automatic email within a minute, and the test engine opens easily without extra software installation. Nothing after 2 hours? Check spam and contact our round-the-clock support. If you fail the corresponding API-577 exam within 60 days of purchase, we give a full refund — send a scanned enrollment slip plus the official Score Report PDF within 2 days of the exam, processed within 7 days. Exclusions: exams within 3 days of purchase, candidate names that don't match the payer, and free or expired products. Or exchange for two equal-value products free.
195 minutes for 110 questions. That's a pace you can train: run timed simulations in the Lead2Passed engine until answering at speed feels normal, and use the analyses to make every wrong answer count.
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. Vendors revise eligibility rules over time, so confirm the current requirements on the official page (official API-577 exam page) before you register.
