Description
This set of plastic replicas display structural steel groove weld flaws. Each inspector or welder should be able to evaluate these flaws for compliance with code requirements. In addition, a back-step sequence replica and cascade replica has been introduced. Being able to recognize these flaws will make you a better welder, fabricator, or inspector.
