AWS-Certified Welding Inspector (CWI) -Welding Metallurgy-1
Module- 2 . Welding Metallurgy- Part-1/2/3/4
Description
The CWI exam consists of three parts
Part A – Fundamentals
Part B – Practical,
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, B & C is 72%
