|Applicants with 8th Grade||9 years of work experience in welding|
|High School Diploma or Equivalent Approved Diploma||At least 5 years of welding work experience|
|For Vocational and Trade Courses||Should have 4 years of welding-based work experience|
|Engineering and Technical Courses – Bachelor or Higher degrees in Welding||Must have 3 years of welding work experience|
|Associate or Higher Degrees in Welding or Non-welding related Engineering Technology, Engineering or Physical Science||Requires 2 years of work experience in welding|
|Bachelor or Higher Degree in Welding Technology or Welding Engineering||Minimum 1 year of welding-based work experience|
Certified Welding Inspector Exam Preparation
After confirming the CWI eligibility, aspiring candidates need to prepare for a certified welding inspector exam. They require an extensive and comprehensive study on welding facts. In addition to this, they need to go deep into the facts and understand all concepts. Memorize all the theories and principles of welding. Besides this, the prospective candidates should select only standard books including handbooks.
Go for Seminars while preparing for the CWI exam. They are full of welding knowledge and provide an intensive experience of welding inspection science, techniques, and documentation. Further, the instructors review the body of knowledge (CWI) and prepare candidates for the CWI exam. Normally, the seminars go for six days.
The seminars consist of lectures, practice questions, online resources, homework assignments, and hands-on learning experiences.
AWS seminars also address three parts of the CWI exam i.e. practical inspection, fundamental knowledge, and code-book navigation. Hence, seminars will take your career to the next level.
Note: Candidates need to register for AWS seminars. Together with this, AWS offers some of the packages to its members.
