API 577 Welding Inspection And Metallurgy


API 577 Welding Inspection & Metallurgy


3 months online training in preparation for the API 577 examination


The objective of the API 577 Welding Inspection and Metallurgy certification program is to provide documented evidence of advanced knowledge and expertise in the area of Welding Inspection and Metallurgy based on the information contained in API RP 577.

API 577 training course is an excellent reference code covering several welding techniques, basic metallurgy, and inspection methods. This valuable qualification demonstrates that inspectors, welders, engineers or QA/QC personnel have obtained excellent knowledge in welding processes.

The course provides an understanding of the welding requirements for fabrication, inspection, and testing requirements of ASME Codes for new construction and how they work with API Codes for post-construction inspection, repairs, and alterations.

It provides the process, oil, gas, petrochemical, and other process industries with the assurance that personnel trained and certified under this internationally recognized program have the required knowledge and experience for the job in the field.

The training is conducted online with lecturer support when required.


The API 577 training course provides participants with the knowledge necessary to pass the exam and includes:

  • Welding inspection
  • Welding processes
  • Welding procedures
  • Welding materials
  • Welder qualification
  • Welding procedure review
  • Non-Destructive Examination
  • Metallurgy
  • Refinery and Petrochemical plant welding issues
  • Terminology and symbols
  • Actions to address improperly made production welds


The American Petroleum Institute (API) offers a certification program for individual in-service inspectors handling the in-service inspection of pressure vessels, pipework and storage tanks. API also manages an expansive catalog catalogue of API ‘codes’ which standardize practice. The certifications are a legal requirement for inspectors in many US states. However, the extension of US ownership to include international facilities and onshore plants, along with the lack of a similarly broad scope of recognized standards in other countries, has resulted in the widespread adoption of API practice within international plant industries. Many other countries regulatory authorities also use these codes to assess evidence of inspector competence. The API certification program is broken down into a series of API programs, programmes known as Individual Certification Programmes (ICPs).

Before applying for the API ICP exam candidates must ensure that they meet the minimum requirements defined by API. The table sets out the requirements for API 510/570/653;


EducationYears of Industry ExperienceExperience Required
BS or higher in engineering or technology1 yearSupervision or performance of inspection activities as described in API 510
2-year Associate’s degree or certificate in engineering or technology2 yearsDesign, fabrication, repair, operation, or inspection of pressure vessels, of which one year must be in supervision or performance of inspection activities as described in API 510
High school diploma or equivalent3 yearsDesign, fabrication, repair, operation, or inspection of pressure vessels, of which one year must be in supervision or performance of inspection activities as described in API 510
No formal education5 or more yearsDesign, fabrication, repair, operation, or inspection of pressure vessels, of which one year must be in supervision or performance of inspection activities as described in API 510

API certificates have become the most regarded, desired, and demanded credentials in the in-service inspection industry, providing a method to improve technical and code knowledge and strengthening the holder’s overall competence and career prospects.

The API examination is held within a Prometric Test Centre. There is a vast range of Prometric Test Centres located worldwide. Please visit the Prometric website to check available Prometric test centre locations near you.

The API exam application is completed online at the API website. You will be asked to provide evidence of previous relevant employment and experience. This experience will be verified by API who will contact the references you provide. At the time of completing your application, you will be asked to pay the relevant API registration fee. This varies depending on the exam you are registering for. Following API’s successful review and approval of your application, you will be provided with an exam eligibility ID number. You will need this number to book your exam with PROMETRIC. You will be provided with a link to PROMETRIC during your
API application. They have a range of locations throughout the world, with the UK sites located in Manchester, London, Glasgow, and Edinburgh. For information on further test center locations please visit the PROMETRIC website for further information.

The API exam application deadline is the date in which you must submit your application to API for review for the given exam cycle.

The API examination window is the period in which you can sit your exam. The examination window typically opens the day immediately after our classroom training; however, we do stagger some of our training dates to accommodate individuals who may be on different work rotations and unable to attend specific classroom dates.

Please contact our helpful team at Wilkinson Coutts for advice should your API application be rejected. Thankfully, rejection of exam applications are rare and so please do not worry about this process.
