The CWI exam consists of three parts

Part C Code Book Applications

Part A is a closed-book exam that consists of 150 questions on the welding fundamentals, terms and definitions, welding processes, nondestructive examination, procedures, symbols, calculations, safety practices, and duties and responsibilities of a CWI

Part B is a practical hands-on test to find the ability to visually identify welding discontinuities and to determine the acceptance or rejection of a weld

Part C is an open book test of Code application to evaluate the applicant’s familiarity and ability with a selected code application

The pass marks for Part A Part B and C is 72 percent
