I have the Certification Manual for Welding Inspection and will be given the Welding Inspection Technology book upon arrival at the seminar. Has anyone compared these texts? I assume some redundancy, but thought I'd ask the forum for any help I can get. While I'm here I'd also like to ask if the AWS Practical Reference Guide for Radiographic Inspection Acceptance Criteria is as handy as it sounds. My job experience in film acceptance was never all that formal and I'd like to know more.
