AWS Certified Welding Inspector, Part-2 -SAW/GMAW/FCAW/EGW

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%
