I’ve received a lot of concerns from prospective students regarding Nondestructive Testing questions in the CWI exam.
Many who have taken CWI prep courses at other institutions found that the coverage of fundamental NDT knowledge is lacking. I imagine this is because most companies that offer CWI prep courses have instructors who may be knowledgeable in practical welding and visual inspection but may not have an NDT background.
AWS does not expect CWIs to be deftly knowledgeable in NDT methods but the newest version of the exam does expect CWIs to have a basic understanding of Ultrasonics, Radiography, Liquid Penetrant, Magnetic Particle and Electromagnetic Testing since NDT of welds is very ingrained in the CWIs work.
AINDT instructors are not only CWIs with a practical welding background but are also ASNT Level IIIs. I myself worked as a code welder am an SCWI and an ASNT level III.
AINDT not only provides CWI prep courses but we also provide Level I, II and III training for Nondestructive Testing in several methods. Rest assured that our CWI prep course will ensure you are sufficiently knowledgeable in Nondestructive testing.
