I have NO welding experience or knowledge so please excuse my ignorance! My boyfriend currently has a job as a Welder and I'm trying to help him prepare for the LA Certified Welder Exam so that he can be certified. I'm trying to find the best book for him to study for the exam, he already has extensive welding knowledge but I've been searching all over the internet and all of the books appear to be for CWI and I'm not sure if that kind of book would be okay to use as well? Below are a few that were looking like the best options, can anyone recommend on of these below or perhaps a better book I should be looking for. ANY help is so appreciated - thank you for your time! :)
~Welding Licensing Exam Study Guide (McGraw-Hill's Welding Licensing Exam Study Guide)
~QuickPass Certified Welding Inspector AWS/CWI Study Guide
