Certified Welding Inspector Exam is one of the best exams for checking skills and leadership roles. So many applicants appear in the CWI exam every year including reappear ones. But all cannot meet the success due to proper study materials and guidance. The test requires hard work and knowledge of basic concepts of welding. For cracking the CWI exam, applicants should read AWS books, welding publications, handbooks, attend seminars, etc. The following are questions and answers for the CWI exam on weld joint geometry and welding symbols.
