Course Description API 577


The main emphasis of this program is on improving and ensuring safety through the use of own-
er / user or third-party welding inspectors specialised in Oil and Gas requirements in a manner that protects employees, the public, and the environment.

The course also provides the understanding of the welding requirements for fabrication, inspection and testing portions 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.

Course participants aspiring to be certified by American Petroleum Institute will undergo a rigor-
ous program to get them well versed with the various code books and standards, including API

Standards that cover maintenance, inspection, rating, repair and alteration of related equipment.

Who Should Attend

No Course pre-requisites requirement.  However, participants who wish to sit for the API exam should have an experience stated below.

AWS-CWI experience listed below.

Welding Engineers, Welding Inspectors, Welding Supervisors, Foreman, NDT Examiners and those seeking an understanding of welding QA/QC will find the course useful. Those aspiring to be qualified to AWS-CWI and/or API 577. Personnel working in the process, oil, gas and petrochemical industry, and who are involved in the design, procurement, engineering construction, operation, maintenance and inspection of welded components and related facilities. Inspectors, engineers, maintenance and QA/QC personnel who work for owner-user companies, inspection companies, fabricators, Ship Building/Ship Repair and Construction, Offshore Fabrication, Railways, maintenance service and repair companies, and EPC’s from petrochemical plants, refineries, power plants, gas / oil pipeline companies, resources companies and palm oil

Training Methodology


Facilitator lead classroom training modules with study of API and ASME Codes Reviewing example problems and solutions Solving practice problems and reviewing detailed solutions.
There will be quizzes throughout the course, and an API 577 /AWS-CWI mock test at the end of the



API Recommended Practice 577: Advanced Welding Inspection and Metallurgy

• American Society of Mechanical Engineers (ASME),
• Boiler and Pressure Vessel Code Section V,
• Nondestructive Examination Section IX, Welding and Brazing Qualifications, Welding and
mechanical testing only
NOTE: Participants are required to bring their own HARDCOPY VERSION of the Reference

Effective May 2013, candidates applying for the API 577 certification program are no longer
required to hold a current API 510, API 570 or API 653 certificate in order to qualify. If you do
hold any of these certificates you automatically qualify for the API 577 exam.
If you do not hold a current certification in either API 510, 570 or 653, then you must have
one of the combinations of education and experience listed in the grid below.
• The minimum years of experience required is based upon your level of education and must
have been acquired within the last ten years.
• CWI examination candidates are required to pass an eye examination.

Pre-course reading requirements are required and candidates are required to purchase required
AWS-API Documentation before attending the course.
Education Minimum (AWS) Experience required
BS or higher in engineering 1 year of experience in the petrochemical industry
2 year technical degree 2 years of experience in the petrochemical industry
High school diploma or Equivalent 3 years of experience in the petrochemical industry
No formal education 4 years of experience in the petrochemical industry
