What can be found in a continuity log?

A continuity log specifically contains a detailed account of a welder's continuous work history, including the types of welds made. This documentation is essential in the welding industry as it tracks the qualifications and certifications of welders over time. By maintaining such records, it ensures that welders are compliant with industry standards and can demonstrate their skills and experience when required. This information is crucial for managing quality control and assuring that the welds performed meet the necessary specifications and safety regulations.

In the context of the options, while other logs can certainly document different aspects of equipment and operational performance, none capture the specifics of a welder’s experience and the nature of work as comprehensively as a continuity log does.
